Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	dabf8dd34a	SBR DSP: unroll sum_square The length is even, so some unrolling can be performed. Timings are for x86: - 32bits: 102c -> 82c - 64bits: 82c -> 69c Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	294c05ce8a	rv34: remove dead code in intra availability check This was an incorrect copy-and-paste to a code not needing the original code. Spotted by Jason in a previous review but forgotten in the commit. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Reimar Döffinger	b5161908e0	SBR DSP: fix SSE code to not use SSE2 instructions. movq from SSE register _to_ memory is an SSE2 instruction.

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
