Anton Khirnov 4735784f1c FATE/opus: increase fuzz for the celt tests 
This seems to be needed on some 32bit arches.
 2014-05-16 14:35:20 +02:00
Anton Khirnov 3b2fbe67bd lavc: properly handle subtitle_header in avcodec_copy_context() 2014-05-15 07:51:39 +02:00
Anton Khirnov efc7df6c1f lavc: preserve the original private data in avcodec_copy_context() 
If a non-NULL codec was passed to avcodec_alloc_context3(), private data
will be already allocated in dest.
 2014-05-15 07:51:16 +02:00
Anton Khirnov c9281a01b7 lavf: drop the zero-sized packets hack 
There should not be any valid reason anymore for passing completely
empty packets to lavf.
OTOH side data-only packets can be useful.
 2014-05-15 07:50:47 +02:00
Anton Khirnov 0c1959b056 lavf: add AVFMT_FLAG_BITEXACT. 
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.
 2014-05-15 07:42:07 +02:00
Anton Khirnov b70d7a4ac7 lavc: add a native Opus decoder. 
Initial implementation by Andrew D'Addesio <modchipv12@gmail.com> during
GSoC 2012.

Completion by Anton Khirnov <anton@khirnov.net>, sponsored by the
Mozilla Corporation.

Anton KhirnovandLuca Barbato 1839fafa95 avconv: Support VDA hwaccel 
Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
 2014-05-11 15:00:03 +02:00
Anton KhirnovandLuca Barbato 67afcefb35 lavc: Add new VDA hwaccel 
It leverages the new hwaccel 1.2 features:

- get_buffer2 is never called
- the internal context is automatically initialized/deinitialized

Anton KhirnovandLuca Barbato 31a46750c7 vda: use hwaccel private data for internal bitstream buffer 2014-05-11 15:00:03 +02:00
Anton KhirnovandLuca Barbato 66e6c8a7b4 lavu: Add a pixel format for new VDA hwaccel 
The current hwaccel is broken and cannot be fixed in a compatible
way. It will be deprecated and replaced with a new one.
 2014-05-11 14:59:59 +02:00
Anton KhirnovandLuca Barbato dd2d3b766b lavc: Add hwaccel private data and init/uninit callbacks 2014-05-11 14:59:07 +02:00
Anton KhirnovandLuca Barbato a871ef0cc9 hwaccel: Rename priv_data_size to frame_priv_data_size

 2014-05-11 14:59:07 +02:00
Anton KhirnovandLuca Barbato 08bb256758 lavc: document which parts of AVHWAccel are private. 2014-05-11 14:59:07 +02:00
Anton KhirnovandLuca Barbato 5c1d7246cd lavc: set AVCodecContext.hwaccel in ff_get_format() 
This way each decoder does not have to do the same thing manually.
 2014-05-11 14:59:07 +02:00
Anton KhirnovandLuca Barbato 632ad2248e lavc: Add an internal wrapper around get_format() 
It will be useful in the following commits.
 2014-05-11 14:59:07 +02:00
Anton Khirnov 9580818c5d avconv: rename OutputStream.opts to OutputStream.encoder_opts 
This makes it more clear what is this variable for exactly.
 2014-05-03 21:44:24 +02:00
Anton Khirnov 01947f07b8 avconv: remove a useless line 
Doing anything with that field when we are doing streamcopy (so the
encoder is not opened) should have absolutely no effect.
 2014-05-03 21:44:10 +02:00
Anton Khirnov 65ed9e7585 avconv: rename 'codec' to 'enc_ctx'

Also, move its declaration into the block where it is actually used.
 2014-05-03 21:43:43 +02:00
Anton Khirnov 650a5206a9 avconv: rename 'icodec' to 'dec_ctx'

 2014-05-03 21:43:24 +02:00
Anton Khirnov f3a6ad22c9 avconv: rename InputStream.opts to InputStream.decoder_opts 
This makes it more clear what is this variable for exactly.

Anton Khirnov ba71c74017 lavc: deprecate AVCodecContext.codec_name 
It is undocumented and has no real use.
 2014-05-01 09:31:32 +02:00
Anton Khirnov e7fc9796d8 lavc: do not use AVCodecContext.codec_name in avcodec_string() 
That field will be deprecated.
 2014-05-01 09:26:57 +02:00
Anton Khirnov ef9732162c rmdec: do not export anything to AVCodecContext.codec_name 
That field will be deprecated and the value that is written there is not
particularly useful.
 2014-05-01 09:26:51 +02:00
Anton Khirnov 6072184e70 asfenc: use codec descriptors instead of AVCodecs to write codec info 
Also, stop using AVCodecContext.codec_name as fallback, since it will be
deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.
 2014-05-01 09:26:20 +02:00
Anton Khirnov 92e4b643df oggparseskeleton: do not use AVCodecContext.codec_name 
That field is undocumented, of dubious use, and will be deprecated.
 2014-05-01 09:26:02 +02:00
Anton Khirnov 18f2514c40 mov: export stsd Compressorname in metadata 
Stop using the undocumented to-be-deprecated AVCodecContext.codec_name
field.

Anton Khirnov 5fccedaa67 lavc: deprecate CODEC_FLAG_INPUT_PRESERVED

Anton Khirnov 6a13505c06 mpegvideo: move the MpegEncContext fields used from arm asm to the beginning 
This should reduce the frequency with which the offsets need to be
updated.
 2014-04-29 14:49:42 +02:00
Anton Khirnov a61c2115fb configure: rework dxva in avconv handling 
Move the dxva check after the dependencies have been detected, make sure
the ole32 library exists.

Fixes build on non-Windows.
 2014-04-28 23:02:56 +02:00
Anton Khirnov 1eb57e1d9b lavc: eliminate tb_unreliable() 
If framerate estimation is enabled, it makes sense to always apply it,
instead of limiting it to a few specific cases.
 2014-04-28 11:34:59 +02:00
Anton Khirnov f9157463db lavf: do not use the parser duration for video 
The parser has no way of knowing video duration, and therefore no video
parsers set it.
 2014-04-22 07:46:03 +02:00
Anton Khirnov 1ae8198bca avconv: always reset packet pts after decoding an audio frame 
Currently, if a decoder sets AVFrame.pts, we'd send the same timestamp
to it twice, which is wrong.
 2014-04-22 07:45:49 +02:00
Anton Khirnov b19a5e5198 lavc: improve AVCodecContext.delay doxy 2014-04-22 07:44:40 +02:00
Anton Khirnov a4ed995cab txd: do not set the codec timebase. 
It is not supposed to be changed from outside of lavc.
Set the stream timebase and average framerate instead.

Anton Khirnov 21d8f4da91 resample: remove an unneeded context variable 2014-04-17 20:08:19 +02:00
Anton Khirnov ac976ed91e lavr: allocate the resampling buffer with a positive size 
This fixes cases where very few input samples (fewer than needed for one
output sample) are passed to lavr at the beginning.

negative source index anymore.

Anton Khirnov b9dea23766 resample: fix avresample_get_delay() return value 
The correct "next" input sample is not the first sample of the
resampling buffer, but the center sample of the filter_length-sized
block at the beginning.

Anton Khirnov baeb59d89b avconv: rewrite output data size tracking 
Store a variable per OutputStream instead of globals for

2pass with multiple output streams.

Anton Khirnov e854b8f9f4 Work around broken floating point limits on some systems. 
The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
    [....]
}
