Martin Storsjö	338978a7c1	libx264: Allow overriding the sliced threads option Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	39da3b223f	avconv: fix counting encoded video size. avcodec_encode_video2() return value is 0 on success, encoded frame size is stored in the packet.	13 years ago
Reimar Döffinger	632eb1bbae	cdxl demux: do not create packets with uninitialized data at EOF. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Alex Converse	3574a85ce5	Replace computations of remaining bits with calls to get_bits_left().	13 years ago
Alex Converse	b70feb4053	amrnb/amrwb: Remove get_bits usage. It is used to parse fixed sized fields out of a single octet. The code is simpler without it.	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	11ac796f7a	dca_parser: parse the sample rate and frame durations	13 years ago
Justin Ruggles	85469f1c9e	libspeexdec: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	adbf61ff8a	libopencore-amr: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	0efa4073bf	alsdec: do not set AVCodecContext.frame_size It is not necessary	13 years ago
Justin Ruggles	f1e73100d9	siff: do not set AVCodecContext.frame_size also, properly set AVCodecContext.bits_per_coded_sample, AVStreasm.start_time, and AVPacket.duration.	13 years ago
Justin Ruggles	ec2e767bf3	amr demuxer: do not set AVCodecContext.frame_size. it is not necessary.	13 years ago
Justin Ruggles	8d1a20aa7c	aiffdec: do not set AVCodecContext.frame_size It is unnecessary. Also, for some codecs we're reading more than 1 frame per packet. Instead we use a private context variable to calculate the bit rate, stream duration, and packet durations. Updated FATE seek test, which has slightly different timestamps due to a more accurate bit rate calculation.	13 years ago
Justin Ruggles	237a855caf	mov: do not set AVCodecContext.frame_size It is not necessary.	13 years ago
Justin Ruggles	9727264220	ape: do not set AVCodecContext.frame_size. prevents lavf from setting incorrect packet durations.	13 years ago
Justin Ruggles	2dd18d4435	rdt: remove workaround for infinite loop with aac avformat_find_stream_info() no longer hangs while waiting for AAC frame_size	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
Justin Ruggles	620b88a302	swfenc: use av_get_audio_frame_duration() instead of AVCodecContext.frame_size This way we can do stream copy without having the demuxer wait until frame_size has been set.	13 years ago
Justin Ruggles	14aecc50fa	rtpenc: use av_get_audio_frame_duration() for max_frames_per_packet It is more reliable than AVCodecContext.frame_size for codecs with constant packet duration.	13 years ago
Justin Ruggles	c019070fda	riffenc: use av_get_audio_frame_duration() For encoding, frame_size is not a reliable indicator of packet duration. Also, we don't want to have to force the demuxer to find frame_size for stream copy to work.	13 years ago
Justin Ruggles	9524cf79df	avcodec: add av_get_audio_frame_duration() function. This is a utility function for the user to get the frame duration based on the codec id, frame size in bytes, and various AVCodecContext parameters.	13 years ago
Justin Ruggles	6699d07480	avcodec: add av_get_exact_bits_per_sample() function This only returns bits per sample when it is exactly correct. That is, the codec contains only raw samples with no frame headers or padding. This applies to basically all PCM codecs and a small subset of ADPCM codecs.	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
Fabian Greffrath	c9dbac36ad	Fix format string vulnerability detected by -Wformat-security. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Diego Biurrun	0a41f47dc1	dv: Do not redundantly initialize struct members to zero.	13 years ago
Mans Rullgard	356ee8d7de	x86: clean up ff_dsputil_init_mmx() This splits ff_dsputil_init_mmx() into multiple functions, one for each MMX/SSE level, somewhat simplifying the nested conditions. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Anton Khirnov	3faa141d15	cmdutils: use new avcodec_is_decoder/encoder() functions. Fixes listing encoders.	13 years ago
Anton Khirnov	44fe77b350	lavc: make codec_is_decoder/encoder() public.	13 years ago
Anton Khirnov	02beb9826b	lavc: deprecate AVCodecContext.sub_id. In most places where it's used, it's as a pointless write-only field. Only rv10 decoder actually reads from it, but it stores some internal version info in it. There is no reason for it to be in a public field.	13 years ago
Anton Khirnov	87392b1fd5	libcdio: add a forgotten AVClass to the private context.	13 years ago
Ronald S. Bultje	1c97b5c4a3	swscale: remove "cpu flags" from -sws_flags description.	13 years ago
Kostya Shishkov	4db4b53dc8	proresenc: give user a possibility to alter some encoding parameters This allows user to select quantisation matrix from different profile, stamp frames with custom vendor string and change target bitrate.	13 years ago
Justin Ruggles	1ba08c94f5	vorbisenc: add output buffer overwrite protection	13 years ago
Justin Ruggles	fe78470a8b	libopencore-amrnbenc: fix end-of-stream handling Use CODEC_CAP_DELAY and CODEC_CAP_SMALL_LAST_FRAME to properly pad and flush the encoder at the end of encoding. This is needed in order to have all input samples decoded.	13 years ago
Justin Ruggles	b0350c1c30	ra144enc: fix end-of-stream handling Use CODEC_CAP_DELAY and CODEC_CAP_SMALL_LAST_FRAME to properly pad and flush the encoder at the end of encoding. This is needed in order to have all input samples decoded.	13 years ago
Justin Ruggles	29e2c85310	nellymoserenc: zero any leftover packet bytes fixes writing of uninitialized packet data	13 years ago
Justin Ruggles	6c7a01621c	nellymoserenc: use proper MDCT overlap delay	13 years ago
