Anton Khirnov	a6733202cc	lavf: make av_interleave_packet_per_dts() private. There is no reason for it to be public, it's only meant to be used internally.	13 years ago
Anton Khirnov	3c90cc2ef2	lavf: deprecate av_read_packet(). The caller can achieve the same effect (i.e. getting raw unparsed/mangled packets) with av_read_frame() and AVFMT_FLAG_NOPARSE \| AVFMT_FLAG_NOFILLIN	13 years ago
Anton Khirnov	40b41be3fa	lavf: use AVStream.discard to disable queueing attached pictures.	13 years ago
Anton Khirnov	01fcc42b90	lavf: requeue attached pictures after seeking. This allows the caller to get them without special code even after seeking before receiving any data.	13 years ago
Martin Storsjö	57151f8674	libavformat: Use AVFormatContext.probesize in init_input This was forgotten in the transition from av_open_input_file to avformat_open_input, see `603b8bc2a1`. This doesn't change anything for the default case where the option isn't set, since PROBE_BUF_MAX is 1048576 (which was used as max probe size earlier) while the default value for the probesize option is 5000000, which for the probe function is clipped to PROBE_BUF_MAX anyway.

Anton Khirnov	8bc5d90a7e	lavf: remove some disabled code.	13 years ago
Anton Khirnov	f35f8eeb0d	lavf: only set average frame rate for video.	13 years ago
Anton Khirnov	9ade26ee91	lavf: remove a pointless check. Timebase is already checked in avpriv_set_pts_info().	13 years ago
Anton Khirnov	cd9a3c3512	lavf: don't select an attached picture as default stream for seeking.	13 years ago
Justin Ruggles	94cf64b81f	cosmetics: reindent	13 years ago
Justin Ruggles	8c1d6ac66a	avformat: do not require a pixel/sample format if there is no decoder Also, do not keep trying to find and open a decoder in try_decode_frame() if we already tried and failed once. Fixes always searching until max_analyze_duration in avformat_find_stream_info() when demuxing codecs without a decoder.	13 years ago
Justin Ruggles	a7fa75684d	avformat: do not fill-in audio packet duration in compute_pkt_fields() Use the estimated duration only to calculate missing timestamps if needed.	13 years ago
Justin Ruggles	6c65cf58fd	lavf: Use av_get_audio_frame_duration() in get_audio_frame_size() Also, do not give AVCodecContext.frame_size priority for muxing. Updated 2 FATE references: dxa-feeble - adds 1 audio frame that is still within 2 seconds as specified by -t 2 in the FATE test wmv8-drm-nodec - durations are not needed. previously they were estimated using the packet size and average bit rate.	13 years ago
Justin Ruggles	9c365fe8ae	avformat: do not require frame_size in avformat_find_stream_info() for CELT In Ogg/CELT, frame_size is found in the same place as the sample_rate and channels, so we do not need to force the frame_size to be parsed.	13 years ago
Justin Ruggles	fbc8c59679	avformat: do not require frame_size in avformat_find_stream_info() for MP1/2/3 It was only needed to avoid a bad time base (and thus non-monotone timestamps) for stream copy to avi.	13 years ago
Justin Ruggles	84b6ae0808	avformat: do not require frame_size in avformat_find_stream_info() for AAC We already will get the needed info because of CODEC_CAP_CHANNEL_CONF	13 years ago
Anton Khirnov	27c7ca9c12	lavf: deobfuscate read_frame_internal(). Split off packet parsing into a separate function. Parse full packets at once and store them in a queue, eliminating the need for tracking parsing state in AVStream. The horrible unreadable loop in read_frame_internal() now isn't weirdly ordered and doesn't contain evil gotos, so it should be much easier to understand. compute_pkt_fields() now invents slightly different timestamps for two raw vc1 tests, due to has_b_frames being set a bit later. They shouldn't be more wrong (or right) than previous ones.	13 years ago
Anton Khirnov	dcee811505	lavf: make read_from_packet_buffer() more flexible. Make packet buffer a parameter, don't hardcode it to be AVFormatContext.packet_buffer. Also move the function higher in the file, since it will be called from read_frame_internal().	13 years ago
Anton Khirnov	52b0943f10	lavf: factorize freeing a packet buffer.	13 years ago
Justin Ruggles	5602a464c9	avcodec: add a Vorbis parser to get packet duration This also allows for removing some of the Vorbis-related hacks.	13 years ago
Anton Khirnov	393fd0d89e	id3v2: remove unused ff_id3v2_read(). Rename ff_id3v2_read_all to ff_id3v2_read().	13 years ago
Anton Khirnov	079ea6ca5f	lavf: export id3v2 attached pictures as streams.	13 years ago
Anton Khirnov	dd2a4bcfd7	lavf: generic code for exporting attached pictures.	13 years ago
Anton Khirnov	7929e22bde	lavf: don't guess r_frame_rate from either stream or codec timebase. Neither of those is guaranteed to be connected to framerate in any way (if it even exists). Fixes bug 56.	13 years ago
Anton Khirnov	d3783f47ee	lavf: don't set codec timebase in avformat_find_stream_info(). It's not supposed to be set outside of lavc.	13 years ago
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

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
