Cut audio data written to AO at the point where current timeline part
ends (before, AO buffers were always completely filled, but playback
of the "extra" audio was then cut short by resetting the AO when
switching timeline parts). This doesn't make much difference for
current playback behavior, but will be used by timeline support for
audio-only files and is necessary for future encoding support where
"playback" of written audio cannot be aborted later.
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
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).

configure had a check for some libraries specific to the maemo
platform. Apparently the code which would have used the results of
this check was never added. Remove the unused check.
Previously the default with --enable-translation was to install all
language files if --language-msg was not explicitly specified. Change
the default to the languages set with the --language option or LINGUAS
environment variable if those are set; if neither is set then the
default is still to install all message languages.
The XML documentation was badly outdated, with various obsolete,
useless and and sometimes actively harmful advice. Delete a lot of the
obsolete stuff, without spending much effort to replace it for now.
In the FAQ section I removed some questions completely; in other cases
I only removed the answer if I thought the entry might be worth
keeping but the answer would need to be updated.
Abort if FFmpeg libraries are not found unless --disable-ffmpeg was
explicitly specified. Note that even if you disable FFmpeg, libavutil
and libswscale are still required and you'll need to add linker flags
for them manually; I didn't try to clean up that case (few people
will want to do that).
Also fix the fallback test used if pkg-config doesn't find the
libraries: fix wrong header name and drop forced -lavcore which isn't
present in all FFmpeg versions. This shouldn't make a difference for
normal use since the pkg-config test should succeed if the libraries
are available.
af_lavcac3enc: use old SampleFormat names without AV_ prefix, the
latter were only added in 2010-11
vd_ffmpeg: add ifdef around CODEC_ID_LAGARITH use
demux_real: use ffmpeg_files/intreadwrite.h
stream/http.c, stream/realrtsp/real.c: define AV_BASE64_SIZE macro for
old libavutil versions lacking it
Enter and Tab are the only named keys (rather than identified by the
printable character they produce) with code below 256. Add a special
case to recognize the Shift modifier with them.
The keycodes.h file contains a KEY_CTRL define, then various control
keys expressed as "KEY_CTRL + 0" and so on. Back in 2002 when the key
name table in input.c was created this KEY_CTRL define was mistakenly
interpreted as a key name, apparently confusing it with the Ctrl key
(even though the input system didn't handle that key back then). As a
result there was an incorrect key name entry with the same key code as
backspace and name "CTRL". This incorrect entry was used when printing
the name of the key. Delete it.
vo_x11_create_vo_window() only called vo_x11_update_geometry() if no
window position had been specified by -geometry or -xineramascreen, to
avoid overwriting the specified position with values from the existing
window. However window size should be initialized to the existing
window here, and setting new window title for -use-filename-title is
also done in vo_x11_update_geometry() (for whatever reason, it doesn't
match what else that function does). Change the code in
vo_x11_create_vo_window() to always call vo_x11_update_geometry() for
size variable and window title updates, but add a flag that tells it
not to update position variables.
The libavcodec AC-3 encoder was changed to use floats, and take
floating point samples as input (the fixed-point version is still
available under the new name "ac3_fixed"). This broke af_lavcac3enc
because it blindly assumed without checking that the "ac3" encoder
would take signed 16-bit integer samples. Improve af_lavcac3enc so
that it checks the sample formats supported by the encoder and can
handle either int16_t or float.
Perhaps an option to keep using integer input but instead switch the
encoder name to "ac3_fixed" for new libavcodec versions would have
some value. Then again, maybe not. Using the preferred data format of
the default "ac3" encoder should normally be best, so probably better
not add such an option unless real need appears.
One of two alternative code parts passing codec extradata to
libavcodec didn't add the buffer padding that libavcodec requires,
resulting in invalid reads beoynd allocated memory area. Fix.
libvorbis and libvorbisidec cannot both be enabled at the same time.
Change configure to enable libvorbis by default if both are
available. It's the more common library, and if someone want to do a
special build for FPU-less systems he can select the library
manually.
Drop internal copy of the tremor library. Note that the internal ogg
demuxer (which is still sometimes useful to work around libavformat
ogg demuxer problems, though it's itself quite buggy) now cannot be
compiled without either external libvorbis or libvorbisidec (tremor).
The "Core dumped ;)" message printed after finishing a stream dump is
known to confuse users but was kept as "humor". Change it to say
"Stream dump complete." instead.
About the only useful part of the BUGS section on the manpage was a
link to mplayerhq.hu, and that doesn't really apply any more (includes
references to Subversion etc). Remove that section and update/remove
some outdated info.
