* avformat: do not require frame_size for Speex.Justin Ruggles2011-10-20
| | | | | Having it there forces decoding of a frame in order to get frame_size, but it is not really needed for proper demuxing or decoding.
* lavf: add avformat_new_stream as a replacement for av_new_stream.Anton Khirnov2011-10-19
| | | | It takes a codec parameter, thus enabling codec-specific defaults.
* lavf: deprecate AVFormatContext.file_sizeAnton Khirnov2011-10-17
| | | | It's too unreliable to be useful. avio_size() should be called instead.
* avformat: add AVInputFormat flag AVFMT_NO_BYTE_SEEK.Justin Ruggles2011-10-13
| | | | This will prevent seeking by bytes for formats that cannot handle this.
* avformat: don't unconditionally call ff_read_frame_flush() when trying to seek.Justin Ruggles2011-10-13
| | | | | This prevents flushing the packet buffer when the input format does not support seeking.
* lavf: fix signed overflow in avformat_find_stream_info()Mans Rullgard2011-10-08
| | | | | | | | | | 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>
* lavf: Avoid using av_malloc(0) in av_dump_formatMartin Storsjö2011-09-30
| | | | | | | On OS X, av_malloc(0) returns pointers that cause crashes when freed. Signed-off-by: Martin Storsjö <martin@martin.st>
* oggdec: add support for Xiph's CELT codecNicolas George2011-09-26
| | | | | | | This patch also introduces CODEC_ID_CELT. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavf: do not set codec_tag for rawvideoMans Rullgard2011-09-25
| | | | | | | | | | | | 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>

* probe: Fix insane flow control.Alex Converse2011-07-29

* lavf: rename enc variable in utils.c:has_codec_parameters()Stefano Sabatini2011-07-17
| | | | | | | 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>

* lavf: restore old behavior for custom AVIOContex with an AVFMT_NOFILE format.Anton Khirnov2011-07-02
| | | | | | | | | | 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>

* asfdec: do not fall back to binary/generic searchVladimir Pantelic2011-05-17
| | | | | | | | | | 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.
