While being able to play videos on a framebuffer device would be nice,
I didn't need it, and couldn't even test it (buggy nvidia binary
drivers that disable framebuffers, buggy DirectFB that crashes when
using the X11 backend). It's just dead weight, get rid of it.
vo_directx was very horrible, and by today it's mostly useless. I didn't
remove it, because there was that-guy who told me in amazement how
awesome mplayer was, because it was the only video player fast enough
for fast playback on his system when using vo_directx. Sorry, that-guy.
When the internal mplayer MPEG demuxer was removed (commit 1fde09db),
the default demuxer when using dvdnav was set to libavformat. Now it
turns out that this doesn't work with libavformat. It will terminate
playback right after the audio runs out (instead of looping it like the
video, or whatever it's supposed to do). I'm not sure what exactly the
problem is, but since 1. even mplayer-svn can't handle DVD menus
directly (missing highlights), 2. DVD menus are essentially worthless,
and 3. I don't directly watch DVDs, don't bother with it and remove it.
For basic playback, there's still libdvdread support.
Also, use pkg-config for libdvdread, and drop support for in-tree
libdvdread. Remove support for in-tree libdvdcss as well.
Remove the win32 loader - the win32 emulation layer, as well as the
code for using DirectShow/DMO/VFW codecs. Remove loading of xanim,
QuickTime, and RealMedia codecs.
The win32 emulation layer is based on a very old version of wine.
Apparently, wine code was copied and hacked until it was somehow able
to load a limited collection of binary codecs. It poked around in the
code segment of some known binary codecs to disable unsupported win32
API calls to make them work. Example from module.c:
for (i=0;i<5;i++) RVA(0x19e842)[i]=0x90; // make_new_region ?
for (i=0;i<28;i++) RVA(0x19e86d)[i]=0x90; // call__call_CreateCompatibleDC ?
for (i=0;i<5;i++) RVA(0x19e898)[i]=0x90; // jmp_to_call_loadbitmap ?
for (i=0;i<9;i++) RVA(0x19e8ac)[i]=0x90; // call__calls_OLE_shit ?
for (i=0;i<106;i++) RVA(0x261b10)[i]=0x90; // disable threads
Just to show how utterly insane this code is. You wouldn't want even
your worst enemy to have to maintain this. In fact, it seems nobody
made major changes to this code ever since it was committed.
Most formats can be decoded by libavcodecs these days, and the loader
couldn't be used on 64 bit platforms anyway. The same is (probably)
true for the other binary codecs.
General note about how support for win32 codecs could be added back:
It's not possible to replace the win32 loader code by using wine as
library, because modern wine can not be linked with native Linux
programs for certain reasons. It would be possible to to move DirectShow
video decoding into a separate process linked with wine, like the
CoreAVC-for-Linux patches do. There is also the mplayer-ww fork, which
uses the dshownative library to use DirectShow codecs on Windows.
Libavformat does not distinguish between "no codec_tag given" and
"codec_tag given, value is 0". 0 can be a valid value. Change
demux_lavf to assume that 0 always means unset for audio. This
prevents incorrect selection of the PCM decoder, which includes
"format 0x0" in its codecs.conf entry. The video case accepts 0 iff
codec_id is RAWVIDEO, but there's no obvious similar check possible
for audio. Thus this could possibly cause issues if a file really uses
0 to mean uncompressed audio.
The libavcodec Musepack SV8 decoder returned 2 bytes consumed for 1
byte input, which triggered a crash due to negative input packet size
later. Add a sanity check to prevent crashes with this type of minor
decoder overreads. Also add a check to parser consumed data.
stream_file always printed "File not found" if it could not open a
file, even though this could be due to other reasons such as
permission problems. Print strerror() information instead. This
changes the output for "mplayer /etc/shadow" from
File not found: '/etc/shadow'
to
Cannot open file '/etc/shadow': Permission denied
Change "run" command to expand properties.

This happened on system without a vdpau driver installed. It's
especially bad because vdpau is the default VO.
I'm not sure when this bug was introduced, and it seems to exist in
upstream mplayer2 too.
init_best_video_out() did not manage the memory for vo->window_title
correctly, and free'd it twice when initialization failed (that's due
to talloc_free_children() being called). When the next VO was tried,
it reused the dangling pointer. Initialize this member somewhere else
lazily instead.
The terminal status line (showing playback status etc.) was too long
for the standard 80 column width in some cases. Shorten the output by
abbreviating some fields with single letters.
Change "(PAUSED!)" to "(Paused)". This looks nicer.
Move the speed field forward and omit the explicit "header". It's
probably intuitively clear that "x2.00" means double speed.
The field showing the playback time in seconds was padded with spaces.
This just takes space away and wasn't really needed.
This was a hack for .mov reference files. The mov demuxer, which
triggered this code, has been removed in commit 1fde09db6f.
The code serves no purpose anymore, and it was bogus in the first
place. (This mov feature should have been handled either by the core's
timeline support, or as normal playlist.)
The assumption is that JPG screenshots are more useful in general.
Lossless screenshots made from lossy videos are just a waste of space.
Increase JPEG quality a bit. There's a tradeoff between quality and
size, and since JPEG is the default now, attempt to balance the
JPEG settings to provide sane defaults for general use cases.
It's not clear why this video filter supported OSD rendering.
The manpage says:
"Can be used for placing subtitles/OSD in the resulting black bands."
But every single VO already does this if vf_expand adds black borders.
This feature is 100% pointless.
Rename -slave to -slave-broken to prevent slave mode applications from
working. Do this to prevent horrible user experiences, in case someone
should attempt to try this version of mplayer with smplayer and others.
This also makes it clear that we don't intend to keep slave mode
compatibility, because the slave mode protocol is horrible and bad.
See the changes in options.rst for further reasons and comments.
Since slave mode is not planned to be kept, this VO is useless and I'm
removing it.
This VO was useful for OSX GUIs. Since in cocoa you can't embed views in
windows from other processes, this VO was writing to a sharedbuffer with
mmap. The OSX GUIs would then read from the buffer and render the image
with an external renderer.
If in the future we will want to support GUIs we will need to reasearch the
IOSurface framework. This allows to share kernel managed image data
across processes and integrates well with OpenGL.
Commit 9c02ae7e95 set the sh variable (see diff) to the struct of
type sh_sub instead the one of sh_stream. Unfortunately this didn't
crash, and merely made the OSD show "unknown" for the language.
Commit 804bf91570 accidentally removed the display of the track
title. Add it back.
The documentation is mostly taken from the help text embedded in the
code of each output driver.
vo_v4l2 and ao_v4l2 have been removed.
Minor modifications to vo_xv, vo_directx and vo_gl.
Commit 7484ae8e2e attempted to introduce two ass_library handles
(as it was needed to deal with how ass_library manages fonts), but the
commit was completely bogus: it assumed osd_state->ass_library would be
used by osd_libass.c only, which is not the case. As result, some of the
subtitle code used the wrong ass_library handle.
We need two ass_library handles in osd_state. The one from the mplayer
core for subtitles (osd_state->ass_library), and one for OSD rendering
(osd_state->osd_ass_library).
The generic hardware pass-through decoder ad_spdif (imported from
mplayer-svn) was mistakenly prefered over the default decoder mpg123.
This is the same as mplayer-svn commit 34192.
The spidfmpa entry was marked as "untested", which for inconceivable
reasons is preferred over entries marked "working". (The probe order
is untested, working, buggy. Possibly to "force" untested codecs to be
tested?) I didn't know this behavior, and skipped the corresponding
mplayer-svn commit 34192, as it looked like it would move up the entry
in autoprobe order (not the reverse), which might have been slightly
dangerous, or at least not something we would have to bother with.
The only change in behavior the incorrect entry caused was that playing
a shoutcast mp3 stream displayed "inf" as time on the mplayer status
line, instead the time since joining the stream. (The same can be seen
when starting mplayer-svn with -ac spdifmpa,mpg123 .) I'm not sure why
this happens; I can only guess that when spdifmpa throws away header
data when it fails initializing, or messes up something else.
The entries of a playlist file usually refer either to local files (in
the same directory as the playlist), or absolute paths like URLs. In
the first case, you want to add the base path of the playlist file to
the files, so that mplayer can find the files. In the second case, the
URLs should not be changed.
Unfortunately, mp_path_join() recognizes URLs as relative paths, and
changes them. E.g. it tried to play /path/to/playlist/http://entry.
Add some code to deal with this properly. The added code uses the same
approach as m_option_type_custom_url in m_option.c, but because it's
so short and trivial, it's perhaps better not to rely on the option
parser code.
It's also unclear whether mp_path_join() should contain this logic,
but maybe it's better to keep the logic of that function clean.
Skipping past the last chapter as user action means playback of the
current file should be ended. The code did this by doing a relative
seek by 1000000000 seconds, which usually caused playback to stop.
However, it displayed a quite ugly and arbitrary looking number in the
status display.
Fix this by explicitly skipping to the next file, instead of issuing a
seek command. (If there is no next file, the player will exit, just as
before.)
(Note: an alternative way to solve this could have been comparing the
mpctx->video_pts with the mpctx->last_seek_pts in print_status(). If
they're the same, it's likely that the video_pts was set to the seek
request time, and we could print another PTS or no PTS instead.)
osd_libass.c used the same ASS_Library object as the player core. This
caused a problem: when playing a new file, all fonts loaded by the
ASS_Library object were unloaded, including the OSD font. Parts of the
OSD would stop being rendered correctly.
Solve this by creating a separate ASS_Library, with its own set of
fonts.
Commit 168293e0ae assumed the OSD drawing routines (which have the
functions osd_draw_text/_ext as entrypoint) would always be called, and
relied on that to reset the change flag.
Some VOs, such as vo_null, didn't do this. Pausing could turn into
endless framestepping in some cases. Restore the part of the OSD drawing
logic that dealt with this. (Alternatively, the VOs could be obliged to
always call the OSD drawing routines, even if the VO doesn't actually
draw the OSD. But it seems even more messy to rely on that.)
This transition to a new VO API started over 4 years ago. It's time to
finally end it, and get rid of the horrible hacks.
Also removes some previously undetected dead code from spudec.c.
The only reason the old VO related header old_vo_defines.h was included
was probably to gain access to the current VO struct in the function
change_movie_aspect(). Make that function take a parameter instead.
This function seems to be unused.
The commit 74df1d8e05 (and f752212c62) replaced the configure
endian check with byte order macros defined by standard headers. It
turns out that MinGW-w64 actually doesn't define these macros in the
sys/types.h system header. (I assumed it does, because a quick test
seemed to work. But that was because gcc -W -Wall doesn't warn against
undefined macros. You need -Wundef for that.) MinGW-w64 has a
sys/params.h header defining these macros, but sys/types.h doesn't
include it, so it's useless without special casing the mplayer code.
Add a hack top configure instead. Define the macros directly, and
assume MinGW-w64 only works on little endian machines.
The other changes are basically random typos and superficial oversights.
The removed VO and AO took MPEG data and decoded it with V4L2. I'm not
exactly sure what's the use of this today, but get rid of it.
As far as feeding video data to V4L2 is concerned, there are other
ways. For example, there is this script, that feeds yuv4mpeg formatted
raw video data to V4L2:
https://raw.github.com/umlaeute/v4l2loopback/master/examples/yuv4mpeg_to_v4l2.c
No effort was put into moving static variables into a priv struct. The
VO wasn't tested, because DirectFB's X11 backend didn't work for me (it
crashed, not just with mplayer, but also SDL applications).
There is lots of badly and inconsistently formatted code left, which
leaves us with the frequent need for cleaning up. This uncrustify
profile can be used for automatic reformatting. The author of this file
is (perhaps) uau.
It's different from mplayer-svn's TOOLS/mp-uncrustify-style.cfg. The
differences and origins of these files are unclear, but the file added
with this commit is probably more consistent with the heavily cleaned
up areas of mplayer2 and this fork.
Although slightly less precise, this sounds less clunky.
This change also causes the --screenshot-filetype option to be renamed
to --screenshot-format.
The encoding branch by divverent can handle of these via libavformat.
Note: for some reason, libav/ffmpeg have a GIF muxer only, and no
demuxer. The gif configure checks needef for the mplayer internal gif
demuxer can't be removed yet.
Most of these are useless or probably even dangerous. Support them
anyway, because it's easy, and we want to replace vo_jpeg without any
disadvantages.
