* lavf: rewrite the av_write_frame() doxyAnton Khirnov2014-02-10
| | | | | Remove some vague / incorrect statements and make the text more specific and less confusing.
* lavf: rewrite the av_interleaved_write_frame() doxyAnton Khirnov2014-02-10
| | | | | Remove some vague / incorrect statements and make the text more specific and less confusing.
* pcmdec: replace a reachable assert with an error checkAnton Khirnov2014-02-10
| | | | | | Libavformat should not make any assumptions about values returned from other libraries. This assert is easily reachable by using a non-raw codec id.
* mxfdec: free descriptor extradata in .read_close()Janne Grunau2014-02-09
| | | | Fixes memleak in fate-mxf-demux.
* lavf: default .ogg audio to libvorbis if we canAndrew Kelley2014-02-09
| | | | | | | | | | | | Since 2007, the Xiph.org Foundation recommends that .ogg only be used for Ogg Vorbis audio files. Source: http://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions However we only do it if we have libvorbis available because the built in vorbis encoder is not as good.

* lavf: improve handling of sparse streams when muxingLuca Barbato2014-02-04
| | | | | | | | | | | | | | | | | | Currently ff_interleave_packet_per_dts() waits until it gets a frame for each stream before outputting packets in interleaved order. Sparse streams (i.e. streams with much fewer packets than the other streams, like subtitles or audio with DTX) tend to add up latency and in specific cases end up allocating a large amount of memory. Emit the top packet from the packet_buffer if it has a time delta larger than a specified threshold. Original report of the issue and initial proposed solution by mus.svz@gmail.com.

* lavf: ignore attachment streams for interleaving purposesAnton Khirnov2014-02-04
| | | | Those streams should never get any packets by definition.
* lavf: do basic sanity checking on muxed packetsAnton Khirnov2014-02-04
| | | | Reject packets for non-existing or attachment streams.
* mxf: Read field dominance flagMatthieu Bouron2014-02-01

* mxf: Handle negative edit_rateLuca Barbato2014-02-01
| | | | Default to 1/25.
* lavf: include 60 fps in guessed standard frame ratesJanne Grunau2014-01-31
| | | | | Due to what looks like an off-by-one error 60 * 12 * 1001 / 12 * 1001 is not tested as standard frame rate in avformat_find_stream_info().
* avformat: utils: Refactor duplicated PRINT macroDiego Biurrun2014-01-29

* avformat: utils: K&R formatting cosmeticsDiego Biurrun2014-01-26
| | | | Also adjust some comment wording / spelling and reorder header #includes.
* rtpdec_asf: Copy the need_parsing field from the chained demuxerMartin Storsjö2014-01-23
| | | | | | | This fixes playback of mp3 streams in rtp/asf. This used to work until c6f1dc8, but mostly by coincidence. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Send a full, absolute timestamp if it isn't monotonically growingMartin Storsjö2014-01-20
| | | | | | | | The normal differential timestamps can't handle negative differences, thus send a full packet header with an absolute timestamp in these cases. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmpproto: Avoid using uninitialized memoryMartin Storsjö2014-01-20
| | | | | | | If the url ends with .flv, we stripped it but didn't initialize rt->playpath, doing av_strlcat on an uninitialized buffer. Signed-off-by: Martin Storsjö <martin@martin.st>
* mov: do not set avg_frame_rate in the demuxerJustin Ruggles2014-01-20
| | | | | | | | | | | The track duration is often not reliable or is not the duration represented by the number of frames. In those cases, avg_frame_rate was reported incorrectly. Removing this code falls back to the default calculation in avformat_find_stream_info(). This is a partial revert of commit c3aeaa540. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* mov: Free an earlier allocated array if allocating a new oneMartin Storsjö2014-01-15
| | | | | | | | | | | It could probably also be considered an error if the pointer isn't null at this point, but then we might risk rejecting some slightly broken files that we might have handled so far.

* mov: Free intermediate arrays in the normal cleanup functionMartin Storsjö2014-01-15
| | | | | | | | | | | | | These arrays are normally freed at the end of mov_read_trak, but make sure they're freed in case mov_read_trak returned early (due to errors) or in case the atoms that allocate arrays are encountered at some other point than within a trak (which we don't have checks against).

* flv: Workaround for buggy Omnia A/XE encoderBenjamin Larsson2014-01-11
| | | | | | | | | The Omnia A/XE encoder writes the explicit extra data incorrectly and wrongly disables parametric stereo. Truncating the extra data by setting the size to 2 works around this. The AAC extra data parser will then only parse the correct parts. Bug-id: 599
