Mans Rullgard	a31e9f68a4	lavf: fix signed overflow in avformat_find_stream_info() On the first iteration through this code, last_dts is always INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in an invalid manner. Although the result is only used if the input values are valid, performing the subtraction is still not allowed in a strict environment. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Martin Storsjö	e81e5e8ad2	lavf: Avoid using av_malloc(0) in av_dump_format On OS X, av_malloc(0) returns pointers that cause crashes when freed. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Nicolas George	4ca59d1948	oggdec: add support for Xiph's CELT codec This patch also introduces CODEC_ID_CELT. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Mans Rullgard	bb416bd68c	lavf: do not set codec_tag for rawvideo 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.

Anton Khirnov	4f731c4429	lavf: restore old behavior for custom AVIOContex with an AVFMT_NOFILE format. 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.

Vladimir Pantelic	69fa23961e	asfdec: do not fall back to binary/generic search 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.	14 years ago

Marton Balint	2c71581698	lavf: fix av_find_best_stream when providing a wanted stream. 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.

Vitor Sessak	ecc297308f	lavf/utils: fix ff_interleave_compare_dts corner case. This should fix behavior introduced by commit `96573c0d76`. 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.
