* lavf: don't set AVCodecContext.has_b_frames in compute_pkt_fields().Anton Khirnov2012-02-22
| | | | | | | | | | | It is not supposed to be done outside lavc. This is basically a revert of 818062f2f346df30f4ec0c0c1f54e8025cc3a80a. It is unclear what issue this was supposed to fix, if it reappears again it will have to be fixed in a more proper place. The wtv-demux test change is because the sample starts with a B-frame.
* avcodec: add duration field to AVCodecParserContextJustin Ruggles2012-02-20
| | | | | This will allow parsers to export the duration of the current frame being output, if known, instead of using AVCodecContext.frame_size.

* lavf: add functions for accessing the fourcc<->CodecID mapping tables.Anton Khirnov2012-01-31
| | | | Fixes bug 212.
* lavc: set AVCodecContext.codec in avcodec_get_context_defaults3().Anton Khirnov2012-01-31
| | | | | | | | | This way, if the AVCodecContext is allocated for a specific codec, the caller doesn't need to store this codec separately and then pass it again to avcodec_open2(). It also allows to set codec private options using av_opt_set_* before opening the codec.
* lavc: add avcodec_is_open().Anton Khirnov2012-01-31
| | | | | | | It allows to check whether an AVCodecContext is open in a documented way. Right now the undocumented way this check is done in lavf/lavc is by checking whether AVCodecContext.codec is NULL. However it's desirable to be able to set AVCodecContext.codec before avcodec_open2().

* lavf: prevent infinite loops while flushing in avformat_find_stream_infoJanne Grunau2012-01-26
| | | | | | | | | If no data was seen for a stream decoder are returning 0 when fed with empty packets for flushing. We can stop flushing when the decoder does not return delayed delayed frames anymore. Changes try_decode_frame() return value to got_picture or negative error. CC: libav-stable@libav.org

* lavf: force single-threaded decoding in avformat_find_stream_infoJanne Grunau2012-01-20
| | | | | | | The H.264 decoder needs SPS and PPS for initialization during multi-threaded decoding. When probed single-threaded SPS and PPS are copied to extradata and are available for proper initialization of the decoder before the first frame is decoded.
* lavf: free packets for muxers implementing interleave_packet().Anton Khirnov2012-01-18

* lavf: flush decoders in avformat_find_stream_info().Anton Khirnov2012-01-03
| | | | | This means that avformat_find_stream_info() now works properly with multiple threads, so there's no need to force thread count to 1.

* lavf: force threads to 1 in avformat_find_stream_info()Anton Khirnov2011-12-18
| | | | | Fixes avformat_find_stream_info() on streams with number of frames < thread count.
* lavf: dealloc private options in av_write_trailerLuca Barbato2011-12-13
| | | | Fix the iformat/oformat typo.
* lavf: add avformat_close_input().Anton Khirnov2011-12-12
| | | | | | | It sets the supplied AVFormatContext pointer to NULL after freeing it, which is safer and its name is consistent with other lavf functions. Also deprecate av_close_input_file().
* lavf: deprecate av_close_input_stream().Anton Khirnov2011-12-12

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* lavf: estimate frame duration from r_frame_rate.Anton Khirnov2011-11-30
| | | | | If r_frame_rate is set, it should be more reliable for this than either codec or stream timebase.
* pthread: do not touch has_b_framesJanne Grunau2011-11-22
| | | | | | | | | | | | | | | | | | Adding the thread count in frame level multithreading to has_b_frames as an additional delay causes more problems than it solves. For example inconsistent behaviour during timestamp calculation in libavformat. Thread count and frame level multithreading are both set by the user. If the additional delay caused by frame level multithreading needs to be considered in the calling code it has all information to take it into account. Should it become necessary to calculate a maximum delay inside libavcodec it should be exported as its own field and not reusing an existing field. Based on a patch by Michael Niedermayer.

* avformat: Accept the ISO8601 separate format as input, tooMartin Storsjö2011-11-16
| | | | | | | | This makes the function accept the format of creation_time as output by demuxers (e.g. the mov demuxer), making the creation timestamp stay intact if transcoding. Signed-off-by: Martin Storsjö <martin@martin.st>
* avformat: Interpret times in ff_iso8601_to_unix_time as UTCMartin Storsjö2011-11-16
| | | | | | | | | | This function is used in muxers for parsing the 'creation_time' metadata key, for converting it to a time value. This makes it match the behaviour of the exported 'creation_time' metadata from demuxers, where it is in UTC, too. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | All current usages of it are incompatible with localization. For example strcasecmp("i", "I") != 0 is possible, but would break many of the places where it is used.
