Anton Khirnov 5f7aecde02 pictordec: break out of both decoding loops when y drops below 0 
Otherwise picmemset can get called with negative y, resulting in an
invalid write.

Anton Khirnov fa09e76010 FATE: add a TAK test 2013-08-08 22:59:42 +02:00
Anton Khirnov 488a0fa689 avconv: support -t as an input option. 
It limits the duration of the data read from a given input.
 2013-08-05 10:54:19 +02:00
Anton Khirnov 811bd07846 avconv: make input -ss accurate when transcoding 
Insert (a)trim filters on the corresponding inputs, so the extra frames
are decoded and discarded.
 2013-08-05 10:53:41 +02:00
Anton Khirnov 56ee3f9de7 avconv: distinguish between -ss 0 and -ss not being used 
Using -ss 0 to drop frames with negative timestamps is a perfectly valid
use case.
 2013-08-05 10:53:12 +02:00
Anton Khirnov 2e661f26f8 avconv: insert extra filters in the same way for both graph inputs and outputs 
This will allow using the same code when one filter can be inserted both
on input and output.
 2013-08-05 10:52:22 +02:00
Anton Khirnov 3799376dd3 lavfi/fifo: fix flushing when using request_samples 
If any samples are still buffered when request_frame returns EOF, they
won't be returned currently.
 2013-08-05 10:52:00 +02:00
Anton Khirnov 06cd4c5a68 avconv: fix usage of deprecated lavfi API 2013-08-05 10:51:41 +02:00
Anton Khirnov 612a5049d9 avserver: do not use a static string as a default for a string option 
Fixes an invalid free.

Bug-id: 448
 2013-08-04 18:47:22 +02:00
Anton Khirnov 51fc88e746 avconv: improve some variable names 
'filter' is too generic, since the functions in question deal with
several filters.

Also add const qualifiers to those variables.
 2013-08-04 15:46:19 +02:00
Anton Khirnov 77cc958f60 lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter() 
This function should never modify the filter.
 2013-08-04 15:46:19 +02:00
Anton Khirnov 8ad3267ce3 oggdec: do not fall back on binary search in the generic code. 
Binary search is already attempted in the format-specific seek function,
so the fallback is only reached if binary search failed already.
 2013-07-02 10:37:22 +02:00
Anton Khirnov 720a1de52f lavc: free the padded last frame during audio encoding properly 2013-06-20 16:49:11 +02:00
Anton Khirnov eeeb5c291d vsrc_movie: do not free avoption variables in uninit() 
The generic code frees them as well. Since av_free was used to free them
instead of av_freep, this would result in a double free.
 2013-06-20 13:27:14 +02:00
Anton Khirnov c9c7bc4493 lavfi: switch ff_default_get_audio_buffer() to av_frame_get_buffer() 
This simplifies the code and avoids using libavcodec-specific
avcodec_fill_audio_frame().
 2013-06-18 11:21:16 +02:00
Anton Khirnov 84d3ff50cd lavc: add a libwavpack encoder wrapper 2013-06-10 21:33:48 +02:00
Anton Khirnov 799f57ac96 lavc: use AVFrame API properly in pad_last_frame(). 
This also simplifies the code.
 2013-06-10 21:19:51 +02:00
Anton Khirnov e816aaacd6 apetag: use int64_t for filesize 
CC: libav-stable@libav.org
 2013-06-04 17:20:19 +02:00
Anton Khirnov 274e134e49 avconv: check that the output format context exists before accessing it 
Fixes a segfault in exit_program() if opening an output file fails.
 2013-06-04 17:20:04 +02:00
Anton Khirnov 8b7dffc2d6 lavfi doxy: improve/extend AVFilter doxy. 2013-06-04 17:18:33 +02:00
Anton Khirnov 2d2d6a4883 lavf: add a raw WavPack muxer. 2013-05-28 18:19:19 +02:00
Anton Khirnov 88de0c7901 apetag: add support for writing APE tags 
This will be useful in the WavPack muxer.
 2013-05-28 18:19:03 +02:00
Anton Khirnov 01656fd476 matroskaenc: support muxing WavPack 2013-05-28 18:18:57 +02:00
Anton Khirnov 794ca87d2b wvdec: split block header parsing into a separate file 
It will be reused by other muxers and demuxers.
 2013-05-28 17:47:59 +02:00
Anton Khirnov 0a1a94450a lavf: rename wv.c to wvdec.c 
wv.c will be used for shared wavpack functions.
 2013-05-28 17:47:30 +02:00
Anton Khirnov 89806691b1 wavpack: check that all the channels were coded. 2013-05-28 17:47:24 +02:00
Anton Khirnov eae1b8451a wavpack: check that there aren't too many blocks per packet 2013-05-28 17:47:17 +02:00
Anton Khirnov 7d039e70a5 wavpack: extract channel information from the bitstream 
This way we don't require the caller to parse the block header. It also
allows the channel configuration to change mid-stream.
 2013-05-28 17:47:04 +02:00
Anton Khirnov 78f75b6fa4 wavpack: extract sample rate from the bitstream 
This way we don't require the caller to parse the block header. It also
allows the sample rate to change mid-stream.
 2013-05-28 17:46:03 +02:00
Anton Khirnov 9b6f47c448 matroskadec: export full wavpack blocks. 
This allows us to get rid of demuxer-specific hacks in the decoder and
will allow streamcopy from matroska once we have a wavpack muxer.
 2013-05-28 08:14:35 +02:00
Anton Khirnov 5074f4545c wavpack demuxer: export full wavpack blocks. 
Currently the demuxer shaves the blocks and exports only the
information that is useful to the decoder.

Exporting the blocks just as they are stored is simpler to understand
and will make remuxing wavpack easier.
 2013-05-28 08:14:05 +02:00
Anton Khirnov 72dee5f40b wavpack: don't set sample format in init. 
We don't know whether it will be float until we look at the data.
 2013-05-28 08:04:07 +02:00
Anton Khirnov 35596bd4f4 wavpack: remove a useless parameter from wavpack_decode_block(). 
The decoder always returns output if an error does not occur.
 2013-05-28 08:03:57 +02:00
Anton Khirnov d1bec4be22 wavpack: return an error on 0-sized blocks 
Such blocks are not valid.
 2013-05-28 08:03:37 +02:00
Anton Khirnov 1d177200ce wavpack: remove a useless check. 
Number of samples in the first block is checked to be strictly positive
earlier in wavpack_decode_frame() and number of samples in all the other
blocks is checked to be equal to the first one.
 2013-05-28 08:03:24 +02:00
Anton Khirnov 0f3a0b24dd wavpack: add an error message to a failure. 2013-05-28 08:03:13 +02:00
Anton Khirnov 474fb0c9d9 wavpack: return 0 instead of samples count from decoding functions 
The caller never cares about the number of decoded samples, so this only
confuses the reader.
 2013-05-28 08:03:02 +02:00
Anton Khirnov 528daa3990 wavpack: switch to planar output 
This simplifies the code and makes it faster.
 2013-05-28 08:01:30 +02:00
Anton Khirnov a7ec3a9a4e wavpack: drop redundant if/else blocks 2013-05-28 08:01:16 +02:00
Anton Khirnov 7b44c99180 wavpack: remove the subframes codec cap 
The decoder always consumes full packets.
 2013-05-28 08:01:08 +02:00
Anton Khirnov c330eba84c lavf: preserve side data when parsing packets. 2013-05-28 08:00:07 +02:00
Anton Khirnov a3fc62e89e configure: make jack depend on pthreads 2013-05-27 21:56:14 +02:00
Anton Khirnov 538bf76737 avconv: make -aspect work with streamcopy 2013-05-27 21:26:06 +02:00
Anton Khirnov 564b7e0c00 matroskadec: silently skip CodecState element. 
mkvmerge apparrently uses it for mpeg1/2 video, but it contains the same
information as CodecPrivate, so it can be ignored.
 2013-05-27 21:25:53 +02:00
Anton Khirnov 8a994b7406 vf_fade: support slice threading 2013-05-24 09:33:05 +02:00

 2013-05-24 09:28:18 +02:00
Anton Khirnov 2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu. 
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.
 2013-05-24 09:28:00 +02:00
Anton Khirnov 90f9a5830b w32pthreads: move from lavc to compat/ 
It will be used in other places than lavc.
 2013-05-24 09:26:54 +02:00
Anton Khirnov e69222c507 doxy: enable TYPEDEF_HIDES_STRUCT 
This means that typedef struct SomeStruct {...} SomeStruct will only be
documented as SomeStruct in the doxy, without a pointless entry in the
typedefs list.
 2013-05-24 09:12:00 +02:00
Anton Khirnov f36d7831d9 pixdesc: mark gray8 as pseudopal 
Many functions treat it as such already.
Fixes Bug 499.

Anton Khirnov 30e256430e lavc/pthread: remove obsolete checks 
Those were useful when avcodec_thread_init() was a public functions. It
was deprecated and removed some time ago, so those checks are not needed
anymore.
