2011-09-30lavf: Avoid using av_malloc(0) in av_dump_formatMartin Storsjö
On OS X, av_malloc(0) returns pointers that cause crashes when freed. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-09-26oggdec: add support for Xiph's CELT codecNicolas George
This patch also introduces CODEC_ID_CELT. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>
2011-09-25lavf: do not set codec_tag for rawvideoMans Rullgard
If the demuxer did not set a codec_tag, there is none and inventing one makes no sense. This change stops the rawvideo "decoder" over-writing user-supplied pixfmt with one derived from the codec_tag. The pixfmt-codec_tag-pixfmt round-trip is lossy since several pixfmts map to the same codec_tag. This fixes fate-lavf-pixfmt with avfilter disabled. Signed-off-by: Mans Rullgard <mans@mansr.com>

A loop control variable was shadowed inside the loop and never updated.
2011-07-17lavf: rename enc variable in utils.c:has_codec_parameters()Stefano Sabatini
Rename it to "avctx", the old name was confusing as the function is used also with decoder contexts. Signed-off-by: Anton Khirnov <anton@khirnov.net>

2011-07-02lavf: restore old behavior for custom AVIOContex with an AVFMT_NOFILE format.Anton Khirnov
av_open_input_stream used to allow this, even though it makes no sense. Make it just print a warning instead of failing, thus restoring compatibility. Note that avformat_open_input() will still reject this combination. Signed-off-by: Anton Khirnov <anton@khirnov.net>

Parenthesis are misplaced in calculation of max_time. Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-05-18asfdec: do not fall back to binary/generic searchVladimir Pantelic
asf_read_seek() inside the asf demuxer already does the right thing, it tries the index and if that fails it uses binary search. If binary search is called from outside of asfdec.c it will fail because the asf code cannot clean up after itself. Therefore introduce AVFMT_NOBINSEARCH that prevents the seek code to fallback to binary search and AVFMT_NOGENSEARCH that prevents the seek code to fallback to generic search.

2011-05-12lavf: fix av_find_best_stream when providing a wanted stream.Marton Balint
In the main loop, stream_number is incremented after checking the stream type, so the search usually will not find the wanted stream. This patch eliminates the useless stream_number variable and introduces a new one, called real_stream_index to store the real stream index of the current stream, no matter if we are looping through all the streams or only the streams of a program.

2011-05-12lavf: fix av_find_best_stream when decoder_ret is given and using a related ↵Marton Balint
stream. Yet another fix for the code originally designed for use without related_stream. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-05-10lavf/utils: fix ff_interleave_compare_dts corner case.Vitor Sessak
This should fix behavior introduced by commit 96573c0d7605672d69b42ae1dcf18764ce47c71a. Av_rescale_rnd() is not lossless so if two timestamps are equal after being rescaled they are not always actually identical. This patch use av_compare_ts() to get always a correct result.

2011-04-30lavf: inspect more frames for fps when container time base is coarseAnssi Hannula
As per issue2629, most 23.976fps matroska H.264 files are incorrectly detected as 24fps, as the matroska timestamps usually have only millisecond precision. Fix that by doubling the amount of timestamps inspected for frame rate for streams that have coarse time base. This also fixes 29.970 detection in matroska.
