Anton Khirnov	655b24c01c	lavf: move the packet keyframe setting code. compute_pkt_fields() is for unreliable estimates or guessing. The keyframe information from the parser is (at least in theory) reliable, so it should be used even when the other guessing is disabled with the AVFMT_FLAG_NOFILLIN flag. Therefore, move setting the packet keyframe flag based on parser information from compute_pkt_fields() to read_frame_internal().	13 years ago
Anton Khirnov	0584e3ca97	lavf: don't set AVCodecContext.has_b_frames in compute_pkt_fields(). It is not supposed to be done outside lavc. This is basically a revert of `818062f2f3`. 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.	13 years ago
Justin Ruggles	e9cda85351	avcodec: add duration field to AVCodecParserContext This will allow parsers to export the duration of the current frame being output, if known, instead of using AVCodecContext.frame_size.	13 years ago
Andrey Utkin	e3cc617263	lavf: fix aspect ratio mismatch message. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	dd6d3b0e02	lavf: add functions for accessing the fourcc<->CodecID mapping tables. Fixes bug 212.	13 years ago
Anton Khirnov	bc90199848	lavc: set AVCodecContext.codec in avcodec_get_context_defaults3(). 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.	13 years ago
Anton Khirnov	af08d9aeea	lavc: add avcodec_is_open(). 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().	13 years ago
Rafaël Carré	420df8b7c4	avformat_write_header(): detail error message Give the exact aspect ratios when there is a mismatch between encoder and muxer. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Janne Grunau	b3461c29c1	lavf: prevent infinite loops while flushing in avformat_find_stream_info 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	13 years ago
Martin Storsjö	f1caf01d5e	libavformat: Add a flag for muxers that support write_packet(NULL) for flushing Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Janne Grunau	59297ad63d	lavf: force single-threaded decoding in avformat_find_stream_info 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.	13 years ago
Anton Khirnov	aa2e4bb058	lavf: free packets for muxers implementing interleave_packet(). Fixes a memleak.	13 years ago
Alex Converse	4df30f7114	utils: Check for extradata size overflows.	13 years ago

Anton Khirnov	6450599e22	lavf: refactor av_read_frame() to make it easier to understand.	13 years ago
Anton Khirnov	212fd3a1f1	lavf: flush decoders in avformat_find_stream_info(). This means that avformat_find_stream_info() now works properly with multiple threads, so there's no need to force thread count to 1.	13 years ago
Janne Grunau	e4e30256f8	threads: default to automatic thread count detection	13 years ago

Anton Khirnov	93fc5a9ff6	lavf: force threads to 1 in avformat_find_stream_info() Fixes avformat_find_stream_info() on streams with number of frames < thread count.	13 years ago
Luca Barbato	4badb386ce	lavf: dealloc private options in av_write_trailer Fix the iformat/oformat typo.	13 years ago
Anton Khirnov	526604545f	lavf: add avformat_close_input(). 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().	13 years ago
Anton Khirnov	3a7f7678eb	lavf: deprecate av_close_input_stream(). And remove all its uses.	13 years ago

Anton Khirnov	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Anton Khirnov	2092232581	lavf: estimate frame duration from r_frame_rate. If r_frame_rate is set, it should be more reliable for this than either codec or stream timebase.	13 years ago
Janne Grunau	0945eddec0	pthread: do not touch has_b_frames 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.

Martin Storsjö	18579f08e7	avformat: Accept the ISO8601 separate format as input, too 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>	13 years ago
Martin Storsjö	4a83541650	avformat: Interpret times in ff_iso8601_to_unix_time as UTC 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>	13 years ago
Mans Rullgard	52767d891c	lavf: fix multiplication overflow in avformat_find_stream_info() Converting to double before the multiplication rather than after avoids an integer overflow in some cases. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Reimar Döffinger	bb3244dee2	Replace all usage of strcasecmp/strncasecmp 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. Instead use our own implementations that always treat the data as ASCII.

Ronald S. Bultje	38a4be3fa7	lavf: use number of output pictures for delay checks. This fixes false positives of has_codec_delay_been_guessed() for streams where not every input picture generates an output picture, such as interlaced H264.	13 years ago
