Uoti Urpala fd50478659 core: improve sub and audio start after timeline part switch
When switching to a timeline part from another file, decoders were
reinitialized after doing the demuxer-level seek. This is necessary
for audio because some decoders read from the demuxer stream during
initialization and the previous stream position before seek could have
been at EOF. However, this initialization sequence could lose first
subtitles or first part of audio.

The problem for subtitles was that the seek itself or audio
initialization could already have buffered subtitle packets from the
new position, and the way subtitles are reinitialized flushes packet
buffers. Thus early subtitles could be lost (even if they were demuxed
- unfortunately demuxers may not know about still active subtitles
earlier in the file, but that's another issue). Fix this by moving
subtitle and video reinitialization before the demuxer seek; they
don't have the problems which prevent that for audio.

Audio initialization can already decode and buffer some output.
However, the seek_reset() call done last would then throw away this
buffered output. Work around this by adding an extra flag to
seek_reset().

wm4 7a699cea28 mixer: reindent/cosmetic changes
There should be no real semantic changes.

Remove the mixer_setbothvolume macro, as it was unused.

Uoti Urpala 7040968be4 core: restructure main play loop, continue audio after video
Restructure parts of the code in the main play loop. The main
functionality difference is that if a video track ends first, now
audio will continue to be played until it ends too.

Now the process also wakes up less often if there's no need to update
video or audio. This will reduce unnecessary wakeups especially when
paused, but may make handling of input events laggier when fd-based
notifications are not supported (like most input on Windows).

Uoti Urpala 06c702ec52 terminal output: if audio/video pts is missing, show "???"
Change the terminal status line to show "???" instead of a huge
negative number if audio or video pts is missing (there was a partial
workaround for audio before, but not video or A-V difference).

Uoti Urpala a816810266 vo_gl: improve 10-bit YUV->RGB conversion accuracy slightly
Modify the YUV->RGB conversion matrix to take into account the
difference between the same color value being x/255 in a 8-bit texture
and x*256/65535 in a 16-bit texture (actually things are stored as
x*4/65535 for 10-bit color, but that can be ignored here). This 0.4 %
difference in the shader float value could make shades of gray in
10-bit (or generally more than 8 bit) YUV produce RGB values with
green slightly higher than red/blue.

Uoti Urpala 3f659fd176 configure: disable live555 by default
Latest liblivemedia version disables APIs we need. The code still
exists in the library and the changelog says the old interface can be
enabled with "#define RTSPCLIENT_SYNCHRONOUS_INTERFACE". However, the
code on the library side is disabled by default too, and seems to be
disabled in distro packages, so defining that in the player does not
help (just delays the failure until link time). It's possible the
distro packages will be changed to enable this, but since dropping
live555 support is desirable anyway, change configure to disable
support by default at least for now.

The live555 code is the only part of the source that's in C++.
Including C headers in code compiled as C++ has caused issues at
times, so deleting this code would have a maintenance benefit.
Reportedly the rtsp support in Libav has improved, so there should
be less need for live555.

Uoti Urpala 7576885677 core: remove old EDL mode (--edl option)
Remove the old EDL implementation that was activated with the --edl
option. It is mostly redundant and inferior compared to the newer
demux_edl support, though currently there's no support for using the
same EDL files with the new implementation and the mute functionality
of the old implementation is not supported. The main reason to remove
the old implementation at this point is that the mute functionality
would conflict with following audio volume handling changes, and
working on the old code would be a wasted effort in the long run as at
some point it would be removed anyway.

The --edlout functionality is kept for now, even though after this
commit there is no code that could directly read its output.

wm4 8a6b0b813a af: fix crash when trying to use volume controls with AC3 pass-through
Changing the volume when softvol is enabled or if the audio output driver
doesn't support volume controls causes insertion of the "volume" filter.
This fails with AC3. Since the filter wasn't removed after that, and the
filter chain was in a bogus state, random crashes occured past this
point.

Fix it by reinitializing the filter chain completely on failure. Volume
controls simply won't work. (This can't be fixed, because AC3 is a
compressed format, and would require additional decoding/encoding passes
in order to support arbitrary volume changes.)

This also affects balance controls.

wm4 a1244111a7 windows support: unicode filenames
Windows uses a legacy codepage for char* / runtime functions accepting
char *. Using UTF-8 as the codepage with setlocale() is explicitly
forbidden.

Work this around by overriding the MSVCRT functions with wrapper
macros, that assume UTF-8 and use "proper" API calls like _wopen etc.
to deal with unicode filenames. All code that uses standard functions
that take or return filenames must now include osdep/io.h. stat()
can't be overridden, because MinGW-w64 itself defines "stat" as a
macro. Change code to use use mp_stat() instead.

This is not perfectly clean, but still somewhat sane, and much better
than littering the rest of the mplayer code with MinGW specific hacks.
It's also a bit fragile, but that's actually little different from the
previous situation. Also, MinGW is unlikely to ever include a nice way
of dealing with this.

wm4 24be34f1e9 cleanup: Silence compilation warnings on MinGW-w64
Some of the code, especially the dshow and windows codec loader parts,
are extremely hacky and likely full of bugs. The goal is merely getting
rid of warnings that could obscure more important warnings and actual
bugs, instead of fixing actual problems. This reduces the number of
warnings from over 500 to almost the same as when compiling on Linux.

Note that many problems stem from using the ancient wine-derived
windows headers. There are some differences to the "proper" windows
header. Changing the code to compile with the proper headers would be
too much trouble, and it still has to work on Unix.

Some of the changes might actually break compilation on legacy MinGW,
but we don't support that anymore. Always use MinGW-w64, even when
compiling to 32 bit.

Fixes some warnings in the win32 loader code on Linux too.

wm4 25417a626d windows: fix format string attributes on MinGW
MinGW maps the "printf" format string archetype to the non-standard
MSVCRT functions, even if __USE_MINGW_ANSI_STDIO is defined and set
to 1. We need to use "gnu_printf" to use the format strings as provided
by vsnprintf and similar functions to get correct warnings.

Since "gnu_printf" isn't necessarily available on other GCC compatible
compilers (such as clang), do this only on MinGW.
2012-03-01 00:22:29 +02:00
wm4 eebe9309ec configure: add __USE_MINGW_ANSI_STDIO on MinGW
This makes MinGW redirect certain stdio functions (such as the sprintf
family) from the MSVCRT libc to a standard compliant MinGW
implementation.

This fixes a crash in talloc.c when compiling mplayer with MinGW-w64.
The problem is most likely with talloc_vasprintf(), which calls
vsnprintf with a small buffer and checks its return value to find out
how much space the formatted string requires. Without this commit,
vsnprintf would always return -1, and then the code calls abort().
(lachs0r figured out this one.)

wm4 3dbb18d91a windows support: remove _UWIN define
The _UWIN define causes the mingw headers not to declare deprecated (on
Windows) function names such as open and mkdir. But the code uses these. I
have no idea why this used to work (if it even did), but the original
reason why it was defined seems to have vanished.

wm4 7332ae76b7 configure: allow changing pkg-config binary with --pkg-config 2012-02-29 23:52:27 +02:00
wm4 2e2c03ecb1 configure: use cross toolchain if --target is given
If --enable-cross-compile is specified, passing
--target=i686-w64-mingw32 for example will check if
i686-w64-mingw32-gcc can be used. This is only done if the compiler
isn't specified via --cc or the CC environment variable.

The same is done for some other build tools, such as pkg-config.
(Only the C compiler will try to use a fallback in this case.)

wm4 cca0b196ba configure: disable cross compilation auto detection
This didn't work very well when cross compiling from Linux to Windows:
it tries to execute an .exe file, which succeeds if wine is installed.
As consequence it detects "no" as result.

In general this won't work if emulation for the target architecture is
available. Remove it.

Uoti Urpala 0c2a302948 configure: show PKG_CONFIG_PATH and CFLAGS in config.log
When the build wrapper repo scripts run configure they set a custom
PKG_CONFIG_PATH environment variable. Show the value of this in
config.log to make it easier to rerun configure with a tweaked version
of the same parameters. Also show CFLAGS if set, as it's likely to
break things.

Uoti Urpala c3ef8607ae vo_png: set AVCodecContext parameters before opening it
Instead of opening avctx in preinit() and setting paramters later,
(re)open it in config() where parameters can be set first. This fixes
a failure to open the codec with new libavcodec versions that check
pix_fmt during avcodec_open2().

Uoti Urpala 9f63c7f17f configure: remove obsolete messages for mtrr / no w32codecs
Remove "Please check mtrr settings at /proc/mtrr" and "NOTE: Win32
codec DLLs are not supported on your CPU" messages printed at the end
of a configure run. mtrr should be irrelevant on today's machines, and
the DLLs are a lot less important nowadays. Also remove mtrr detection
logic that was only used to decide whether or not to print that
message. Bizarrely, there were --enable-mtrr and --disable-mtrr
options for this too (with no effect except for the message).

Uoti Urpala 0e752d5863 vo: reject vo_redraw_frame() if no frames have been drawn
vo_xv crashed if existing frames had been lost due to a config() call
in the middle of a file and vo_redraw_frame() was called. Add checks
to reject vo_redraw_frame() unless at least one frame has been flipped
after the the last configuration change, so individual VOs do not have
to deal with this case.

Uoti Urpala a43a4aafd0 configure, build: support compiling without libpostproc
libpostproc has been removed from Libav and the library now exists as

Uoti Urpala 8d20859716 configure: simplify pkg-config handling, drop other tests
Add helper function pkg_config_add() that checks for the presence of a
package and also adds cflags/ldflags if it is found. Change existing
pkg-config-using feature tests to use that. Also change the freetype
test that used a separate libfreetype-config binary before; using
pkg-config instead helps cross-compiling. Drop other kinds of checks
(such as test compiles) from these tests. It's possible that this
could cause problems on some (broken) systems, but that can't be
verified without user testing.

Uoti Urpala 9f9bbb3c8b demux_lavf: update growing file size info for AVSEEK_SIZE
demux_lavf was returning a static size value when libavformat queried
file size with AVSEEK_SIZE. Add code to query the stream for possibly
changed value first. This at least improves seeking with growing MPEG
files; before seeks would never go beyond the part of the file that
existed when the stream was first opened.

Uoti Urpala d0bae74702 osd: erase terminal OSD line with mp_msg() instead of printf()
The terminal OSD line was written with mp_msg(MSGT_CPLAYER, ...) but
erased with printf(). This meant that disabling MSGT_CPLAYER messages
would prevent the terminal line from being printed, but a line
(probably unrelated) would still be cleared. Change the clearing code
to use mp_msg(MSGT_CPLAYER, ...) too.

wm4 e796c7495c screenshot: fix libav API use (pix_fmt and some other things)
Libavcodec started checking that avctx->pix_fmt is set when opening
an encoder. The existing code (originally from vf_screenshot.c) only
set it afterwards, which now made screenshots fail. Fix the code to
set parameters before calling avcodec_open2().

Also fix some minor things, which seems to make it work for other
encoders. This could be used to add more libavcodec based image
writers. Fix memory leak (missing av_free(avctx)).

Uoti Urpala da52c9400d vd_ffmpeg: fix flushing of buffered frames
The vd_ffmpeg decode() function returned without doing anything if the
input packet had size 0. This meant that flushing buffered frames at
EOF did not work. Remove this test. Have the core code skip such
packets coming from the file being played instead (Libav treats
0-sized packets as flush signals anyway, so better assume such packets
do not represent real frames with any codec).

Uoti Urpala b317b92819 vd_ffmpeg: adjust buffered frame count based on threads again
Libav has changed back to not modifying avctx->has_b_frames based on
the extra buffering caused by thread use. Add back the code to do the
adjustment on the player side once again.

The timing mode using the buffering info is no longer the default, so
in most cases having this right or not won't matter for playback.

Uoti Urpala fc6a9e4a3e build: switch to libavutil bswap.h and intreadwrite.h
Remove the private bswap and intreadwrite.h implementations and use
libavutil headers instead.

Originally these headers weren't publicly installed by libavutil at
all. That already changed in 2010, but the pure C bswap version in
installed headers was very inefficient. That was recently (2011-12)
improved and now using the public bswap version probably shouldn't
cause noticeable performance problems, at least if using a new enough
compiler.

Uoti Urpala cdb6d157cc demux_lavf: use Libav RIFF tag lists directly
Change demux_lavf to use CodecID -> RIFF tag mappings that are now

ffmpeg_files/taglists.c. That can now be deleted.

Uoti Urpala db8cdc73e3 Update Libav API uses
Change various code to use the latest Libav API. The libavcodec
error_recognition setting has been removed and replaced with different
semantics. I removed the "--lavdopts=er=<value>" option accordingly,
as I don't think it's widely enough used to be worth attempting to
emulate the old option semantics using the new API. A new option with
the new semantics can be added later if needed.

Libav dropped APIs that were necessary with all Libav versions
until quite recently (like setting avctx->age), and it would thus not
be possible to keep compatibility with previous Libav versions without
adding workarounds. The new APIs also had some bugs/limitations in the
recent Libav release 0.8, and it would not work fully (at least some
avcodec options would not be set correctly). Because of those issues,
this commit makes no attempt to maintain compatibility with anything
but the latest Libav git head. Hopefully the required fixes and
improvements will be included in a following Libav point release.

Uoti Urpala c4093e7d87 vd_ffmpeg: explicitly set thread count even if 1
Libav started automatically enabling threaded decoding a while ago.
This is not safe, as it means callbacks can suddenly get called from
other threads and outside calls to libavcodec. We need to know when
threading will be used and disable thread-unsafe callbacks in those
cases. Explicitly set thread count to 1 instead of leaving it at 0
(which triggers the autodetection) when we are not requesting more
threads; this should make sure that autodetection on libavcodec side
will not be used.

wm4 668654098e audio: change default preference order of AO drivers
Now PulseAudio is preferred over ALSA, which in turn is preferred over
OSS. This should give best results on all systems. On systems with
PulseAudio, we will always use it natively, rather than through the
suboptimal ALSA emulation (which the default ALSA output is normally
redirected to when PulseAudio is active; ALSA hardware devices will
not be, but to use those the user must set AO explicitly in any case,
so changing the defaults makes no difference). The fallback from
ao_pulse to ao_alsa causes no noticeable delay on systems without
PulseAudio. On systems with ALSA, we won't attempt to use OSS anymore.

Also, move OpenAL above SDL. OpenAL should generally work better than
SDL.

wm4 6cecbf38c1 af_volume: do not change data when volume is 1
When the volume multiplier is 1, the data shouldn't be changed, but the
code actually multiplied each sample with 255/256. Change the factor to
256, and hope there wasn't a good reason for the value 255.

Additionally, don't work on the data if it wouldn't be changed anyway.
This is a micro-optimization.

This doesn't touch the code path for the float format.

wm4 5489d0e89a core: print pause status message only once on console
Since the recent OSD redraw changes, every GUI expose event causes the
message "=====  PAUSE  =====" to be printed on console. This was a bit
annoying, so change it so that it is only printed once when going into
paused mode. It's also printed again if the cache status changes (when
playing URLs), or when the status line is printed during pause mode (when
you seek while paused).

This also removes some minor code duplication.

Uoti Urpala 30afc64532 stream_ffmpeg: switch to libavformat avio API
stream_ffmpeg was using the libavformat URLContext API. This API has

Uoti Urpala 1bd5871762 Libav API updates (remove most deprecated-in-0.7 uses)
Update various code using Libav libraries to remove use of API
features that were deprecated at Libav release 0.7. I think this
removes them all with the exception of URLContext functions still used
in stream_ffmpeg.c (at least other uses that generated deprecation
warnings with libraries from 0.7 are removed).

Uoti Urpala 37e4a928ca configure, build: require at least Libav 0.7
Require versions of the Libav libraries corresponding to Libav release

libavutil   51.7.0
libavcodec  53.5.0
libavformat 53.2.0
libswscale   2.0.0
libpostproc 52.0.0

Also disable the fallback to simple header check if these libraries
could not be found with pkg-config; now compiling without pkg-config
support for these always requires explicitly setting --enable-libav
and any needed compiler/linker flags. The simple check would have let
compilation proceed even if a version mismatch was detected.
