The timeline code previously added to support Matroska ordered
chapters allows constructing a playback timeline from segments picked
from multiple source files. Add support for a new EDL format to make
this machinery available for use with file formats other than Matroska
and in a manner easier to use than creating files with ordered
chapters.
Unlike the old -edl option which specifies an additional file with
edits to apply to the video file given as the main argument, the new
EDL format is used by giving only the EDL file as the file to play;
that file then contains the filename(s) to use as source files where
actual video segments come from. Filename paths in the EDL file are
ignored. Currently the source files are only searched for in the
directory of the EDL file; support for a search path option will
likely be added in the future.
Format of the EDL files
The first line in the file must be "mplayer EDL file, version 2".
The rest of the lines belong to one of these classes:
1) lines specifying source files
2) empty lines
3) lines specifying timeline segments.
Lines beginning with '<' specify source files. These lines first
contain an identifier used to refer to the source file later, then the
filename separated by whitespace. The identifier must start with a
letter. Filenames that start or end with whitespace or contain
newlines are not supported.
On other lines '#' characters delimit comments. Lines that contain
only whitespace after comments have been removed are ignored.
Timeline segments must appear in the file in chronological order. Each
segment has the following information associated with it:
- duration
- output start time
- output end time (= output start time + duration)
- source id (specifies the file the content of the segment comes from)
- source start time (timestamp in the source file)
- source end time (= source start time + duration)
The output timestamps must form a continuous timeline from 0 to the
end of the last segment, such that each new segment starts from the
time the previous one ends at. Source files and times may change
arbitrarily between segments.
The general format for lines specifying timeline segments is
[output time info] source_id [source time info]
source_id must be an identifier defined on a '<' line. Both the time
info parts consists of zero or more of the following elements:
1) timestamp
2) -timestamp
3) +duration
4) *
5) -*
, where "timestamp" and "duration" are decimal numbers (computations
are done with nanosecond precision). Whitespace around "+" and "-" is
optional. 1) and 2) specify start and end time of the segment on
output or source side. 3) specifies duration; the semantics are the
same whether this appears on output or source side. 4) and 5) are
ignored on the output side (they're always implicitly assumed). On the
source side 4) specifies that the segment starts where the previous
segment _using this source_ ended; if there was no previous segment
time 0 is used. 5) specifies that the segment ends where the next
segment using this source starts.
Redundant information may be omitted. It will be filled in using the
following rules:
- output start for first segment is 0
- two of [output start, output end, duration] imply third
- two of [source start, source end, duration] imply third
- output start = output end of previous segment
- output end = output start of next segment
- if "*", source start = source end of earlier segment
- if "-*", source end = source start of a later segment
As a special rule, a last zero-duration segment without a source
specification may appear. This will produce no corresponding segment
in the resulting timeline, but can be used as syntax to specify the
end time of the timeline (with effect equal to adding -time on the
previous line).
Examples:
----- begin -----
mplayer EDL file, version 2
< id1 filename
0 id1 123
100 id1 456
200 id1 789
300
----- end -----
All segments come from the source file "filename". First segment
(output time 0-100) comes from time 123-223, second 456-556, third
789-889.
----- begin -----
mplayer EDL file, version 2
< f filename
f 60-120
f 600-660
f 30- 90
----- end -----
Play first seconds 60-120 from the file, then 600-660, then 30-90.
----- begin -----
mplayer EDL file, version 2
< id1 filename1
< id2 filename2
+10 id1 *
+10 id2 *
+10 id1 *
+10 id2 *
+10 id1 *
+10 id2 *
----- end -----
This plays time 0-10 from filename1, then 0-10 from filename1, then
10-20 from filename1, then 10-20 from filename2, then 20-30 from
filename1, then 20-30 from filename2.
----- begin -----
mplayer EDL file, version 2
< t1 filename1
< t2 filename2
t1 * +2 # segment 1
+2 t2 100 # segment 2
t1 * # segment 3
t2 *-* # segment 4
t1 3 -* # segment 5
+0.111111 t2 102.5 # segment 6
7.37 t1 5 +1 # segment 7
----- end -----
This rather pathological example illustrates the rules for filling in
implied data. All the values can be determined by recursively applying
the rules given above, and the full end result is this:
+2 0-2 t1 0-2 # segment 1
+2 2-4 t2 100-102 # segment 2
+0.758889 4-4.758889 t1 2-2.758889 # segment 3
+0.5 4.4758889-5.258889 t2 102-102.5 # segment 4
+2 5.258889-7.258889 t1 3-5 # segment 5
+0.111111 7.258889-7.37 t2 102.5-102.611111 # segment 6
+1 7.37-8.37 t1 5-6 # segment 7
Remove code that tries to select audio track during demuxer
initialization from demux_mkv and demux_lavf. Just leave audio
disabled at that point; the higher-level select_audio() function will
call the demuxer to switch track later anyway.
Removing this unneeded code also fixes use of these demuxers as the
main demuxer with -audiofile. Before the automatic track selection
would have enabled an audio track (if the file had any); as the main
demuxer was not used for audio the unused packets from this enabled
track would accumulate until they reached queue size limits.
The select_audio() call was done on the main demuxer, not -audiofile
one (the "if (mpctx->num_sources)" test in the previous code was
always true). Call it on the -audiofile demuxer instead. The
-audiofile stuff still needs a proper cleanup later though.
Remove --with-glib-config, --with-gtk-config, --enable-gui,
--disable-gui, --enable-gtk1, --disable-gtk1. The only one of these
that still had any effect was --enable-gui which printed a warning
about GUI removal and exited. The --with options were still shown in
help output, the rest had already been deleted from that.
Commit de42015a97 ("demux_mkv: read tags") added code that
failed to initialize a loop variable. Fix. No visible problems caused
by the bug have been reported.
Delete mp3lib which has been the default mp3 decoder until now. In
addition to being an unnecessary embedded library it now fails to
compile correctly with the new gcc-4.6, producing noise.
After the deletion the default decoder priority for mp3 will be first
libmpg123 (a newer version of the code that mp3lib was based on) if
available, then ffmp3float which should be available in all normal
compiles. I think that some tweaking may be required as these decoder
alternatives get wider testing, but any problems should be solvable
and there should be no need for mp3lib.
Reordering to libavcodec channel order was broken with libavcodec
versions using float input to the ac3 encoder because the reordering
code still assumed int16 sample size. Fix.
Duration may now be set for packet types other than subtitles; as far
as I can tell nothing should care. A check requiring valid duration
values for subtitles is removed, because duration may not be properly
set for all bitmap subtitle types; hopefully this doesn't make the
behavior with (already broken) subtitles without duration worse.
In 59058b54a7 (from svn r31129) Aurelien
changed demux_lavf -vid indexing, but failed to change the initial
video stream selection based on -vid to match. Fix.
If the argument given to demux_lavf audio/video switch code is not one
of -2, -1, or valid audio/video ID the code will treat it the same as
-2 (switch to no sound / no video). However the returned index was not
set to -2 in this case. Fix. Also change the returned index from -1 to
-2 when staying at no sound / video.
Fix bugs in the handling of stream index values in video stream
switching. This is similar to what commit 90bedd0b87
did for audio.
Also clean up the corresponding audio code a little bit.
Windows pthreads requires certain functions to be called to initialize
itself. It can do that through DllMain but no such luck when linked
statically; mplayer needs to call the initialization explicitly.
Recent ffmpeg-mt versions changed the API for setting the number of
decoding threads to use (I'm not sure whether dropping backwards
compatibility was intentional or not). As a result only one thread was
used. Make the thread setting compatible with the new API to restore
proper multithreaded decoding.
Libavcore was merged back to libavutil. Change the mga_template.c
include of libavcore/imgutils.h to match. This means that split
libavcore/libavutil versions won't work any more; but since this only
affects people who enable vo_mga and there was no released version
using the split libs I won't bother with any conditionals for the
include.
Change license indicated for compiled binaries to GPL 3 to match
talloc.c which is LGPL 3+. Note that at least for now the source
licenses have NOT been changed - almost everything is still GPL 2+ or
compatible, not GPL 3+.
Disable compilation of demux_ty_osd.c because of its GPL v2-only
license. This only affects TiVo files with -subcc. After this no
v2-only code should get compiled (yuv4mpeg_intern.h has a v2-only
license, but the contents of the header look like they're not
copyrightable).
When doing a precise seek video_out->frame_loaded was left to true
while frames were being skipped. However vo_get_buffered_frame()
always returns success if a frame is already loaded; due to this the
EOF detection in update_video() never triggered, and a hr-seek past
EOF could cause a soft hang (commands were still processed and it was
possible to seek again to exit the loop). This could also happen with
Matroska files using ordered chapters if an underlying file was
actually shorter than the chapter that was supposed to come from it.
Then seeking to a timestamp after the end of the file but before the
end of the chapter would trigger the bug.
Fix the problem by setting frame_loaded to false when we decide to
skip the frame in question.
As things currently are the --ffmpeg-source-dir option will cause a
compilation failure. Maybe the video filters that depend on internal
FFmpeg headers to work should be deleted completely; for now I'll
remove the option from the help output as it can only confuse normal
users.
The internal libdvdcss version was only compiled if you used internal
libdvdread too; and libdvdread was not included in the sources, so
that'd only happen if you manually added libdvdread in the build
tree. Keeping libdvdcss for that case probably isn't worth it, so
delete it from the tree. The build system part is still there, so an
internal build is possible if you add the directory back.
Add new file timeline/tl_matroska.c. Move the code that parses
ordered chapter information from Matroska files and creates the
timeline structure based on that to the new file.
Initialize the format parameter given to open_stream() in the moved
code. The previous uninitialized value shouldn't have caused any
visible effects.
Drop support for specifying demuxer types by numeric ID (options
-demuxer, -audio-demuxer and -sub-demuxer). Stop printing the numeric
values in "-demuxer help" output. Convert the list of DEMUXER_TYPE_XXX
defines to "enum demuxer_type".
Remove some unused lines from demuxer.h. Make some demuxer.c functions
static. Move new_ds_stream() declaration from demuxer.h to stream.h
(the function is defined in stream.c). Clean up some code in mplayer.c
that had commented-out free_demuxer_stream() calls.
Force Makefile to always run version.sh to potentially regenerate
version.h. Drop compiler version and 'git-' prefix from version
number. Match only git tags starting 'v'+number when generating
version number; leave the 'v' out from the result.
Change DVB SPU stream format in TS demuxer so it can be decoded by
libavcodec (as soon as lavc is fixed not to fail just because of an
extra padding byte).
