Anton Khirnov 8d900aa4d0 lavfi: remove disabled FF_API_GRAPH_AVCLASS cruft 2012-06-26 13:14:59 +02:00
Anton Khirnov a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init() 
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.
 2012-06-26 13:13:48 +02:00
Anton Khirnov 19ad567311 avconv: fix -force_key_frames 
parse_forced_keyframes() relies in encoder timebase being set, so call
it from transcode_init() after it is known.
 2012-06-26 13:10:33 +02:00
Anton Khirnov 980e65f119 ape: create audio stream before reading tags. 
Tags may contain attached picture, which will be exported as video
streams.

This ensures that the audio stream is always the first.
 2012-06-24 07:55:33 +02:00
Anton Khirnov a7b8ff94b1 mov: make a length variable larger. 
Right now, it's uint16_t, but for itunes metadata a 32bit number is
stored in it.
 2012-06-24 07:54:29 +02:00
Anton Khirnov fd269d6253 avconv: remove a forgotten debugging printf. 2012-06-24 07:15:32 +02:00
Anton Khirnov df98bf22cb avconv: use more descriptive names for hardcoded filters. 
Also ensure that all such filters get a non-NULL name. Should fix FATE
failures on some architectures after
58b049f2fa.
 2012-06-24 07:15:32 +02:00
Anton Khirnov 6fc7d9a078 avconv: remove redundant handling of async. 
Because of a mistake during merging the code for simple and complex
filtergraphs, -async inserts an asyncts filter both on input and output.
Remove the output hunk.
 2012-06-24 07:15:31 +02:00
Anton Khirnov 7a8059eb9c doc/filters: fix typo. 2012-06-24 07:15:31 +02:00
Anton Khirnov dc07fb6f7b lavfi: add join audio filter. 
It joins multiple input streams into one multi-channel output.
 2012-06-22 21:26:18 +02:00
Anton Khirnov f75be9856a lavfi: allow audio filters to request a given number of samples. 
This makes synchronization simpler for filters with multiple inputs.
 2012-06-22 21:23:42 +02:00
Anton Khirnov 58b049f2fa lavfi: support automatically inserting the fifo filter when needed. 
This breaks libavfilter ABI.
 2012-06-22 21:06:01 +02:00
Anton Khirnov fa06623930 lavfi/audio: eliminate ff_default_filter_samples(). 
It currently does the following:
1) get a zeroed audio buffer
2) copy some properties (but not the data) of the input buffer to it
3) pass this buffer to the output filter
This looks useless and is indeed not used by any filters, therefore
delete it.

Make ff_null_filter_samples() (just pass the buffer to the next filter)
the new default.
 2012-06-22 20:58:19 +02:00
Anton Khirnov 9ee3334840 libspeexenc: add supported sample rates and channel layouts. 2012-06-22 19:03:24 +02:00
Anton Khirnov e026c9b390 lavfi/audio: don't set cur_buf in ff_filter_samples(). 
It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.
 2012-06-21 09:27:05 +02:00
Anton Khirnov 4a97ff2fa7 lavfi/fifo: add audio version of the fifo filter. 2012-06-21 07:38:35 +02:00
Anton Khirnov 27570e211a fifo: fix parenthesis placement. 2012-06-21 07:38:28 +02:00
Anton Khirnov 394a2a0452 lavfi: rename vf_fifo.c -> fifo.c 
It will be used for audio too.
 2012-06-21 07:38:14 +02:00
Anton Khirnov a50b756280 lavc: remove stats_in from AVCodecContext options table. 
Its documentation states that it is allocated/freed by the caller, but
it is declared as an AV_OPT_TYPE_STRING AVOption. Since
367732832f the AVOptions system frees
strings automatically. This can be considered an API break, since it
won't work when the caller doesn't use av_malloc() to allocate the
memory or wants to use the string after closing the codec.

Since there is not much value in this field being an AVOption, the best
solution is to remove it from the options table.
 2012-06-21 07:36:44 +02:00
Anton Khirnov ae702edf43 flacdec: read attached pictures. 2012-06-16 17:10:23 +02:00
Anton Khirnov a5db8e4a1a lavf: don't segfault when a NULL filename is passed to avformat_open_input() 
This can easily happen when the caller is using a custom AVIOContext.

Behave as if the filename was an empty string in this case.

Anton Khirnov 9baeff9506 lavfi: replace AVFilterContext.input/output_count with nb_inputs/outputs 
This is more consistent with naming in the rest of Libav.
 2012-06-13 11:13:22 +02:00
Anton Khirnov 9d0bfc5052 lavfi: make AVFilterPad opaque after two major bumps. 
It will allow adding new fields to it without ABI breaks.
 2012-06-13 11:11:33 +02:00
Anton Khirnov 84b9fbe055 lavfi: add avfilter_pad_get_type() and avfilter_pad_get_name(). 
This will allow making AVFilterPad opaque for the calling apps, since
those are the only two fields that can be useful to the users.
 2012-06-13 11:10:17 +02:00
Anton Khirnov 6d58358a3a lavfi: make avfilter_get_video_buffer() private on next bump. 
They are only useful inside filters and we don't allow user filters for
now.
 2012-06-13 11:09:15 +02:00
Anton Khirnov d625136877 lavfi: add channelsplit audio filter. 2012-06-12 21:38:59 +02:00
Anton Khirnov 47b812e9ce avconv: support only native pthreads. 
Our w32pthreads wrapper has various issues and is only supposed to be
used in libavcodec.
 2012-06-12 13:44:38 +02:00
Anton Khirnov 5db5169e46 avconv: multithreaded demuxing. 
When there are multiple input files, run demuxing for each input file in
a separate thread, so reading packets does not block.

This is useful for achieving low latency when reading from multiple
(possibly slow) input streams.
 2012-06-10 08:12:23 +02:00
Anton Khirnov b0f0dfc485 Bump lavu minor and add an APIChanges entry for audioconvert functions. 2012-06-10 08:04:01 +02:00

 2012-06-10 08:02:02 +02:00
Anton Khirnov 803391f719 lavfi: remove request/poll and drawing functions from public API on next bump 
They are only useful inside filters and we don't allow user filters for
now.
 2012-06-05 09:38:16 +02:00
Anton Khirnov fa417fcd27 lavfi: make avfilter_insert_pad and pals private on next bump. 
They are only useful inside filters and we don't allow user filters for
now.
 2012-06-05 09:38:08 +02:00
Anton Khirnov b74a1da49d lavfi: make formats API private on next bump. 
It is only useful inside filters and we don't allow user filters for
now.
 2012-06-05 09:37:30 +02:00
Anton Khirnov 67339f6eb4 avplay: use buffersrc instead of custom input filter. 
We do not allow user filters, so avtools shouldn't use them either.

It also allows to reuse buffer management code from avconv, thus
reducing duplication.
 2012-06-05 09:36:10 +02:00
Anton Khirnov d55c2e05b5 avtools: move buffer management code from avconv to cmdutils. 
It will be used by avplay.
 2012-06-05 09:35:58 +02:00
Anton Khirnov 3ffa233595 avconv: don't use InputStream in the buffer management code. 
Use just the pointer to the head of the buffer pool.

This will allow sharing the code with avplay.
 2012-06-05 09:35:39 +02:00
Anton Khirnov e58b75f7ff avconv: fix exiting when max frames is reached. 
frame number should never be strictly larger than max frames, so the
if() was never triggered.
 2012-06-05 09:35:08 +02:00
Anton Khirnov 2b1f105f1b doc/avconv: add some details about the transcoding process. 2012-06-04 14:22:16 +02:00
Anton Khirnov a982e5a031 avidec: make scale and rate unsigned. 
The specs say they are unsigned 32bit integers.
 2012-06-04 14:18:49 +02:00
Anton Khirnov bb7431f4fc avconv: check output stream recording time before each frame returned from filters 
There may be multiple frames returned, so with just one check we can
write more than requested to the output.
 2012-06-04 14:18:34 +02:00
Anton Khirnov a508e7a1ff avconv: split selecting input file out of transcode(). 2012-06-04 14:18:18 +02:00
Anton Khirnov 2f51ec2b94 avconv: split checking for active outputs out of transcode(). 2012-06-04 14:17:52 +02:00
Anton Khirnov 8eb9bf0933 avfiltergraph: make some functions static. 
They are not used outside of avfiltergraph.c
 2012-06-04 14:17:39 +02:00

Anton Khirnov a91943bcef librtmp: don't abuse a variable for two unrelated things. 2012-06-03 15:46:16 +02:00
Anton Khirnov 007aedeebf librtmp: add rtmp_app and rtmp_playpath private options. 
This makes it easier to switch between native rtmp and librtmp.
 2012-06-03 15:45:55 +02:00
Anton Khirnov cf3a1948e9 avpacket: fix duplicating side data.

 2012-06-03 10:22:42 +02:00
Anton Khirnov c9cc76290f avconv: extend -r to work on any input stream. 
This is done by automatically inserting a setpts filter.
 2012-05-29 19:19:17 +02:00
Anton Khirnov 4f81a5072a doc/avconv: expand documentation for the -s option. 2012-05-29 19:19:16 +02:00

Anton Khirnov 8daf21d567 avconv: merge configuration code for complex and simple filters 
Some tests change because -s now inserts the scaler to the end instead
of beginning of the filtergraph.
 2012-05-29 19:19:16 +02:00
Anton Khirnov a977d91e28 avconv: split configuring input filters out of configure_complex_filter 2012-05-29 19:19:16 +02:00

Anton Khirnov ce353a881f lavfi: fix incorrect comment. 
poll_frame()/request_frame() are used for audio too.
 2012-05-22 21:37:44 +02:00
Anton Khirnov c04c533f62 lavfi: remove avfilter_null_* from public API on next bump. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.
 2012-05-22 21:36:23 +02:00
Anton Khirnov 43c7a01e98 lavfi: remove avfilter_default_* from public API on next bump. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.
 2012-05-22 21:33:26 +02:00
Anton Khirnov ccefa89f39 avfiltergraph: smarter sample format selection. 2012-05-22 21:29:36 +02:00
Anton Khirnov 0629f6128e avconv: rename transcode_audio/video to decode_audio/video. 
Those functions do only decoding now, encoding is run from
poll_filters().
 2012-05-22 21:29:06 +02:00
Anton Khirnov f297dd3812 asyncts: reset delta to 0 when it's not used. 
Fixes an invalid write.

Anton Khirnov 39885a4bd7 avconv: reindent 2012-05-18 19:41:58 +02:00
Anton Khirnov 74b961db77 avconv: replace -vsync cfr code with the fps filter. 
Invented timestamps for the h264 tests return to something resembling
sanity.

In the idroq-video-encode test when converting 25 fps -> 30 fps the
fifth frame gets duplicated instead of the sixth.
 2012-05-18 19:38:40 +02:00
Anton Khirnov 755cd4197d mov: enable parsing for VC-1. 
This makes lavf discard broken timestamps for non-B frames in
samples/isom/vc1-wmapro.ism.
 2012-05-18 19:38:21 +02:00
Anton Khirnov 54c5dd89e3 lavfi: Add fps filter. 
Partially based on a patch by Robert Nagy <ronag89@gmail.com>
 2012-05-18 19:33:54 +02:00

Anton Khirnov 01e98b1b00 avconv: fix behavior with -ss as an output option. 
Don't return from poll_filters() immediately, there may be other frames
and/or other streams to handle.

Fixes a memleak.
 2012-05-17 19:37:58 +02:00
Anton Khirnov d894752387 avprobe: don't print format entry name when only one was requested 
This is easier to parse with automated tools.
 2012-05-16 18:35:05 +02:00
Anton Khirnov d89eca507c Add missing version bumps and APIchanges/Changelog entries. 2012-05-15 06:57:31 +02:00

Anton Khirnov 4c64fed37c lavfi: move formats-related functions from default.c to formats.c 
It's more convenient to have them all in one file.
 2012-05-15 06:52:01 +02:00
Anton Khirnov c5432d3ca4 lavfi: move video-related functions to a separate file. 
This is easier to follow than having them randomly scattered in
avfilter.c and defaults.c.
 2012-05-15 06:51:23 +02:00
