| * amr demuxer: do not set AVCodecContext.frame_size.Justin Ruggles2012-03-051-2/+0
| | | | | | | | it is not necessary.
| * aiffdec: do not set AVCodecContext.frame_sizeJustin Ruggles2012-03-052-30/+36
| | | | | | | | | | | | | | | | | | 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.
| * mov: do not set AVCodecContext.frame_sizeJustin Ruggles2012-03-051-13/+0
| | | | | | | | It is not necessary.
| * ape: do not set AVCodecContext.frame_size.Justin Ruggles2012-03-051-1/+0
| | | | | | | | prevents lavf from setting incorrect packet durations.
| * rdt: remove workaround for infinite loop with aacJustin Ruggles2012-03-051-3/+0
| | | | | | | | avformat_find_stream_info() no longer hangs while waiting for AAC frame_size
| * avformat: do not require frame_size in avformat_find_stream_info() for CELTJustin Ruggles2012-03-051-3/+0
| | | | | | | | | | 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.
| * avformat: do not require frame_size in avformat_find_stream_info() for MP1/2/3Justin Ruggles2012-03-051-3/+0
| | | | | | | | | | It was only needed to avoid a bad time base (and thus non-monotone timestamps) for stream copy to avi.
| * avformat: do not require frame_size in avformat_find_stream_info() for AACJustin Ruggles2012-03-051-1/+0
| | | | | | | | We already will get the needed info because of CODEC_CAP_CHANNEL_CONF
| * swfenc: use av_get_audio_frame_duration() instead of AVCodecContext.frame_sizeJustin Ruggles2012-03-051-5/+1
| | | | | | | | | | This way we can do stream copy without having the demuxer wait until frame_size has been set.
| * rtpenc: use av_get_audio_frame_duration() for max_frames_per_packetJustin Ruggles2012-03-051-2/+9
| | | | | | | | | | It is more reliable than AVCodecContext.frame_size for codecs with constant packet duration.
| * riffenc: use av_get_audio_frame_duration()Justin Ruggles2012-03-051-5/+23
| | | | | | | | | | | | 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.
| * avcodec: add av_get_audio_frame_duration() function.Justin Ruggles2012-03-054-1/+157
| | | | | | | | | | 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.
| * avcodec: add av_get_exact_bits_per_sample() functionJustin Ruggles2012-03-052-11/+33
| | | | | | | | | | | | 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.
| * lavf: deobfuscate read_frame_internal().Anton Khirnov2012-03-056-172/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * lavf: make read_from_packet_buffer() more flexible.Anton Khirnov2012-03-051-12/+20
| | | | | | | | | | | | | | | | 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().
| * lavf: factorize freeing a packet buffer.Anton Khirnov2012-03-051-17/+13

| * x86: clean up ff_dsputil_init_mmx()Mans Rullgard2012-03-051-417/+475
| | | | | | | | | | | | | | | | 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>

* | Revert "wmaenc: check final frame size against output packet size"Michael Niedermayer2012-03-051-6/+4
| | | | | | | | | | | | | | | | This condition cannot happen, if it can it is a bug that MUST be fixed. And i very happily volunteer to fix it if someone reports a case to me that fails. This reverts commit 5d652e063bd3a180f9de8915e5137aa4f938846d.
* | alsa: fix timefilter usage.Nicolas George2012-03-052-1/+3
| | | | | | | | | | The period argument is supposed to be the number of samples since the last update.
* | timefilter: allow variable periods.Nicolas George2012-03-051-2/+2
| | | | | | | | Initially found and designed by Michael Niedermayer.
* | timefilter: internally compute feedback factors.Nicolas George2012-03-054-17/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The feedback factors for the timefilter are directly computed from the expected period. This commit changes the init function to accept the period itself and compute the feedback factors internally, rather than having all client code duplicate the formulas. This commit also actually fixes the formulas: the current code had sqrt(2*o), but the correct formula, both theoretically and according to experimental testing, is sqrt(2)*o. Furthermore, it adds an exponential to feedback factors larger than 1 with large periods.

| | | | | | | | | | | | | | 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.
