Stefano Pigozzi c7bf5111c7 core: path: run uncrustify
Even if this is not so bad as other files, I need to add some stuff so...
why not!?

`uncrustify -l C -c TOOLS/uncrustify.cfg --no-backup --replace core/path.h`
`uncrustify -l C -c TOOLS/uncrustify.cfg --no-backup --replace core/path.c`

The header was unchanged by the tool.

Stefano Pigozzi 9201cfe2bd ass_mp: allow to use a custom fontconfig configuration file
This allows to use a fontconfig fonts.conf that is customized for mpv. The
configuration file is assumed to be located at `~/.mpv/fonts.conf`. If not
found the default fcontconfig config file is used.

wm4 5f999d94df video: silence warnings for missing libavutils pixel formats
Using vf_screenshot on Libav printed useless/misleading error messages
when playing 10 bit h264 with a VO that supports 8 bit yuv420p only:

    Unsupported format 444p14le
    Unsupported format 444p14be
    ...

The cause of this is that vf_scale is inserted to handle the format
conversion, and tries to find a pixel format with best quality. This
includes the 14 bit and 12 bit formats, which don't exist on Libav.
vf_screenshot tries to query whether Libav's libswscale supports it,
resulting in these error messages. (In theory, vf_scale is missing this
check, but it doesn't matter in practice.)

Since this warning is rather useless anyway, because all input video
comes from libavcodec, and only the conversion into the other could
possibly fail. Silence the warning by raising it to verbose message
level.

Closes #7.

wm4 962a97a2db sd_lavc: keep subs on subtitle track switching
Keep the currently displayed subtitles even when the user cycles through
subtitle tracks, and the subtitle is decoded by libavcodec (such as
vobsubs). Do this by not clearing the subtitles on reset(). reset() is
also called on seek, so check the start PTS whether the subtitle should
really be displayed (there's already an end PTS). Note that sd_ass does
essentially something similar.

The existing code has checks for whether the PTS reported by the demuxer
is invalid (MP_NOPTS_VALUE). I don't know under what circumstances this
can happens, so fall back to the old behavior if the PTS is invalid.

wm4 c6fbf91a89 manpage: mark HTTP related options as deprecated/broken
Commit c02f25 switched the "http://" protocol to use ffmpeg's HTTP
implementation (stream_lavf.c), instead of the mplayer internal one
(http.c). Unfortunately, it turns out that there are some network
related options that are not respected by stream_lavf.c, and
consequently do not work anymore for "http://" URLs. This might be
fixed later. Mark them as deprecated for now, as it might take
arbitrarily long until this is taken care of.

wm4 3f949cf50b mplayer: prefer audio PTS over video PTS for status line
This slightly improves display of the current playback time in files
with sparse video packets (like video tracks containing a slow MJPG
slideshows as in [1]), or audio files with cover art image attachments.
While the video PTS is always "stuck" at the last frame displayed or
the last seek, audio is usually continuous. Given sane samplerates and
working audio drivers (to query how much of the current audio buffer has
been played), the audio PTS should always be more reliable.

wm4 fdbf437055 core: allow disabling display of "album art" in audio files
ffmpeg pretends that image attachments (such as contained in ID3v2
metadata) are video streams. It injects the attached pictures as packets
into the packet stream received with av_read_frame().

Add the --audio-display option to allow configuring whether attached
pictures should be displayed. The default behavior doesn't change
(images are displayed).

Identify video streams, that are actually image attachments, with "[P]"
in the terminal output.

Modify the default stream selection such that real video streams are
preferred over attached pictures. (This is just for robustness; I do not
know of any samples where images are added before actual video streams
and could lead to bad default stream selection with the old code.)

wm4 74ab902dea audio: remove support for native alaw/mulaw/adpcm output
This is considered a worthless feature. Note that alaw/mulaw/adpcm input
is unaffected: such data is handed to libavcodec and "decoded" to linear
PCM.

wm4 071d24e19d audio/decode: remove ad_dvdpcm and use ad_lavc for DVD PCM
ad_dvdpcm reads MPEG specific headers directly (passed through codecdata
by demux_mpg), so you couldn't use ffmpeg's "pcm_dvd" with demux_mpg.
Change demux_mpg to set the correct audio parameters directly. The code
for this is taken from ad_dvdpcm.

ad_dvdpcm is evil because it still does partial packet reads (with
demux_read_data()), and it's redundant to libavcodec anyway.

wm4 2dd2d9bcfc audio/decode: remove ad_pcm and use ad_lavc for PCM
Since libavcodec doesn't have a "generic" PCM decoder, we have to go out
of out way to make it look like ad_lavc provides one: make it provide a
pseudo "pcm" decoder, which maps some format tags manually to the
individual libavcodec PCM decoders.

Format tags which uniquely map to one libavcodec could be mapped via
codecs.conf. Since defining these in tag_map[] is much shorter (one line
vs. a full codec entry in codecs.conf), and since we need tag_map[]
anyway, we don't use codecs.conf for these.

ad_pcm is evil because it still does partial packet reads (with
demux_read_data()), and it's redundant to libavcodec anyway.

wm4 180944fe28 stream_lavf/demux_lavf: export/use HTTP MIME type
This is a fix for web radio streams that send raw AAC [1]. libavformat's
AAC demuxer probe is picky enough to request hundreds of KBs data, which
makes for a slow startup. To speed up stream startup, try use the HTTP
MIME type to identify the format. The webstream in question sends an AAC
specific MIME type, for which demux_lavf will force the AAC demuxer,
without probing anything.

ffmpeg/ffplay do the same thing. Note that as of ffmpeg commit 76d851b,
av_probe_input_buffer() does the mapping from MIME type to demuxer. The
actual mapping is not publicly accessible, and can only be used by
calling that function. This will hopefully be rectified, and ideally
ffmpeg would provide a function like find_demuxer_from_mime_type().

wm4 222a5cf7c0 demux_lavf: make minimum probe score customizable, remove lavf_preferred
libavformat wants to read a full ~400KB of data to determine whether
it's really AAC. This causes slow startup with AAC web radio streams [1]
(possible due to a broken initial packet). There are similar issues
with other file formats.

Make the probe "score" (libavformat's mechanism for testing file
formats) configurable with the -lavfdtops:probescore option. This allows
lowering the amount of data read on probing. If the probe score is below
the probescore option value, demux_lavf will try to get a higher score
by feeding more data to libavformat, until the required score or the
max. probe size is reached.

Remove the lavf_preferred demuxer entry. This had a purpose in
mplayer-svn, but now there doesn't seem to be any good reason for it
to exist. Make sure that our native "good" demuxers are above
demux_lavf in demuxer_list[] instead (so that they are preferred).

wm4 eb787267c8 stream: handle mms streaming with ffmpeg
Use ffmpeg (stream_lavf) instead of internal mms support (asf_streaming.c)
for mms://, mmsh://, mmst:// URLs.

The old implementation is available under mp_mms:// etc.

There are some caveats with this:
- mms:// now always maps to mmsh://. It won't try mmst://. (I'm not sure
  if mms:// URLs really can use the mmst protocol, though.)
- MMS streams under the http:// prefix are not handled. (ffmpeg ticket
  #2001.) (Was already broken in mpv since c02f25.)
- It downloads all video streams now. MMS streams often have redundant
  video streams, which encode the main stream at different quality. The
  client is supposed to select one according to its bandwidth
  requirements. (Explicit MMS stream selection has been broken in mpv
  for a while, because MPOpts.vid maps to the stream number, not the
  demuxer's stream ID - but the old logic doesn't work anyway when
  using demuxer_lavf as opposed to demux_asf.)

wm4 b3fb7c2cad core: improve seeking in external files
This affects streams loaded with -subfile and -audiofile. They could get
out of sync when they were deselected, and the main file was seeked. Add
code to seek external files when they are selected (see
init_demux_stream()).

Use avformat_seek_file() under certain circumstances. Both av_seek_frame()
("old" API) and avformat_seek_file() ("new" API) seem to be broken with
some formats. At least the vobsub demuxer doesn't implement the old API
(and the old API doesn't fallback to the new API), while the fallback
from new API to old API gives bad results. For example, seeking forward
with small step sizes seems to fail with the new API (tested with
Matroska by trying to seek 1 second forward relative to priv->last_pts).
Since only subtitle demuxers implement the new API anyway, checking
whether iformat->read_seek2 is set to test whether the old API is not
supported gives best results. This is a hack at best, but makes things
work.

Remove backwards seeking on seek failure. This was annoying, and only
was there to compensate for obscure corner cases (see 1ad332). In
particular, files with completely broken seeking that used to skip back
to the start on every seek request may now terminate playback.

wm4 7288834a4c sub: use ffmpeg decoder for DVD subs
Do this only if demux_lavf is used. Using demux_mpg and the ffmpeg DVD
subtitle decoder doesn't work. The problem is probably that demux_mpg
doesn't join split sub packets, while demux_lavf does. The internal
DVD sub decoder (spudec.c) can, while ffmpeg's dvdsub can't. I do not
know whether this is the actual problem.

If DVD playback is used, create "fake" vobsub-style text extradata
(like .idx files) to pass resolution and palette information to the
ffmpeg decoder. We could use the "palette" AVOpt and avcodec_set_dimensions()
instead, but it's actually simpler this way. Note that the decoder
doesn't parse any other fields. Also note that DVD playback still uses
demux_mpg by default, so this code is inactive unless -demuxer lavf is
specified. This is mainly preparation for the case when we manage to get
rid of demux_mpg for DVD playback.

The subreader.c ASS parser (used when playing an external ASS subtitle

syntax instead of correctly reading it from the "Format: " line in the
file, but tried to support a varying amount of fields by guessing
where the text field (which should be last) begins. This guessing code
was buggy in many ways. Remove it and hardcode skipping 9 commas
before the text field, which should work for most files. I don't
consider the --no-ass case important enough to implement correct
parsing now. Also fix the code removing formatting tags, which failed
to remove the second in a pair of two consecutive tags.

wm4 3486f59fe2 core: automatically pause on low cache
When the cache fill status goes below a certain threshold, automatically
pause the player. When the cache is filled again, unpause again.

This is intended to help with streaming from http. It's better to pause
a while, rather than exposing extremely crappy behavior when packet
reads during decoding block the entire player.

In theory, we should try to increase the cache if underruns happen too
often. Unfortunately, changing the cache implementation would be very
hard, because it's insane code (forks, uses shared memory and "volatile"
etc.). So for now, this just reduces the frequency of the stuttering if
the network is absolutely too slow to play the stream in realtime.

wm4 c02f252938 stream_lavf: use ffmpeg for http/https streaming
The internal mplayer http implementation is terrible and old. Try to use
ffmpeg instead. Enable ffmpeg https as well (we don't have native
support for it and never will).

Enable the cache for ffmpeg streams. In theory, we want to enable the
cache for network streams only (or at least, not enable it for files),
but there doesn't seem to be any way to query this. ffmpeg has its own
read-cache, but apparently it doesn't get filled asynchronously (only
to the degree internal socket/kernel buffers do).

Should it turn out that the mplayer implementation is better than
ffmpeg's in some way (unlikely), this commit might be reverted until
ffmpeg is ready. So far, the ffmpeg implementation seems to work very
well though.

The original mplayer stream implementation is made available under
"mp_http://" and "mp_http_proxy://". This is for testing, until the
http implementation is completely removed. Note that this is unlikely
to happen soon: ffmpeg doesn't support Microsoft streaming, while
mplayer has some support. This code has dependencies on http.

Note: "http_proxy://" doesn't work anymore. Use "httpproxy://" to get

Using https requires enabling OpenSSL in ffmpeg by adding
the --enable-openssl switch to ffmpeg's configure.

wm4 6294c78549 cache: simplify further
This commit is separate from the previous one to separate our own
changes from changes merged from mplayer2 (as far as that was possible).

Make it easier for stream implementations to request being cached. Set
a default cache size in stream.c, and remove them from various stream
implementations. Only MS streaming support sets a meaningful cache size.

Make querying cache size saner. This reduces the amount of #ifdefs
needed.

Uoti Urpala 2d58234c86 cache: refactor how cache enabling is done
Code enabling the cache by default for network streams did that by
modifying the value of the "cache" option. This wasn't sane, as
multiple streams may be created and all share the same options. Change
the code to not modify options but store data in the stream instance
instead.

Conflicts:
	core/mplayer.c
	demux/demux.c
	stream/cache2.c
	stream/network.c
	stream/network.h
	stream/pnm.c
	stream/stream.c
	stream/stream_rtp.c

Merged from mplayer2 commit e26070. Note that this doesn't solve any
actual bug, as the playlist crashing bug has been fixed before.

Since the global cache size option value is not overwritten anymore, the
option doesn't need to be restored on end of playback (M_OPT_LOCAL).

Stephen Hutchinson c082240c62 video: add support for 12 and 14 bit YUV pixel formats
Based on a patch by qyot27. Add the missing parts in mp_get_chroma_shift(),
which allow allocation of such images, and which make vo_opengl
automatically accept the new formats. Change the IMGFMT_IS_YUVP16_LE/BE
macros to properly report IMGFMT_444P14 as supported: this pixel format
has the highest numerical bit width identifier (0x55), which is not
covered by the mask ~0xfc. Remove 1 bit from the mask (makes it 0xf8) so
that IMGFMT_IS_YUVP16(IMGFMT_444P14) is 1. This is slightly risky, as
the organization of the image format IDs (actually FourCCs + mplayer
internal IDs) is messy at best, but it should be ok.

Stephen Hutchinson 54ce8af6e0 build: identify the build time of the binary in the versioning output
Based on a patch by qyot27. Add export LC_ALL=C on top of version.sh to
make the output locale independent.

Note that the build time will not be updated on every "make" invocation,
but only when the git revision is updated. This is a good thing, as
repeated make invocations should not rebuild the binary. (This would
break "sudo make install" too.)

wm4 7146a57cfe demux_gif: remove this demuxer in favor of libavformat
The gif support in libavformat/libavcodec as of ffmpeg commit 5603b2
can handle animated gif. The internal demuxer is not needed anymore.

wm4 dd3260185a demux_lavf: add support for libavdevice
libavdevice supports various "special" video and audio inputs, such
as screen-capture or libavfilter filter graphs.

libavdevice inputs are implemented as demuxers. They don't use the
custom stream callbacks (in AVFormatContext.pb). Instead, input
parameters are passed as filename. This means the mpv stream layer has
to be disabled. Do this by adding the pseudo stream handler avdevice://,
whose only purpose is passing the filename to demux_lavf, without
actually doing anything.

Change the logic how the filename is passed to libavformat. Remove
handling of the filename from demux_open_lavf() and move it to
lavf_check_file(). (This also fixes a possible bug when skipping the
"lavf://" prefix.)

libavdevice now can be invoked by specifying demuxer and args as in:

    mpv avdevice://demuxer:args

The args are passed as filename to libavformat. When using libavdevice
demuxers, their actual meaning is highly implementation specific. They
don't refer to actual filenames.

Note:

libavdevice is disabled by default. There is one problem: libavdevice
pulls in libavfilter, which in turn causes symbol clashes with mpv
internals. The problem is that libavfilter includes a mplayer filter
bridge, which is used to interface with a set of nearly unmodified
mplayer filters copied into libavfilter. This filter bridge uses the
same symbol names as mplayer/mpv's filter chain, which results in symbol
clashes at link-time.

This can be prevented by building ffmpeg with --disable-filter=mp, but
unfortunately this is not the default.

This means linking to libavdevice (which in turn forces linking with
libavfilter by default) must be disabled. We try doing this by compiling
a test file that defines one of the clashing symbols (vf_mpi_clear).

To enable libavdevice input, ffmpeg should be built with the options:

    --disable-filter=mp

and mpv with:

    --enable-libavdevice

Originally, I tried to auto-detect it. But the resulting complications
in configure did't seem worth the trouble.

wm4 aa2c07542f demux_lavf: do not prefix filename passed to libavformat with "mp:"
Opening files with the libavformat AVISynth demuxer ("avs"/avisynth.c)
fails, because the filename we pass to avformat_open_input() is prefixed
with "mp:". Normally, this doesn't matter, because data is read with the
stream interface. The AVISynth demuxer can't use this, because the
Avisynth API (apparently) can't read scripts from memory, and requires
a filename.

The "mp:" prefix used to be required when mplayer's stream layer was
made available as protocol to ffmpeg. This was replaced by setting
custom stream callbacks in de4908 (svn commit 25499), but the prefix
wasn't removed. Since this prefix doesn't have any purpose anymore and
prevents AVS playback from functioning, remove it. Fixes #5.

wm4 3b4682183c vo_xv: try harder to get correctly aligned pointers/strides
To get guaranteed alignment for the chroma planes with typical YV12
playback, we have to double the alignment on the image width, as the
chroma planes have half the image width.

Clear the image with black instead of green to hide scaling artifacts
on the right border of the screen.

(It might be possible to create the image layout ourselves by not
calling XvShmCreateImage(), and filling in our own image width and exact
strides, but that's probably too risky: the Xv client library sends an
X protocol request to query the real image dimension and strides. It is
unknown to me whether X servers or drivers would generally accept an
image with mismatching parameters, even if the image is conceptually
valid.)

Allocate the image with av_malloc() in the non-SHM case. I suspect the
non-SHM case doesn't matter much, though.

wm4 9ace4f1f49 configure: don't check for inttypes.h, it always exists
The presence of inttypes.h is guaranteed by POSIX. We don't need to
check for it. We don't need to provide a compatibility header either.

Apparently libc5 systems didn't provide inttypes.h. libc5 is ancient,
unmaintained, and not used by modern Linux systems.
