* avformat/pcm: decrease target audio frame per sec to 10Marton Balint2024-03-1615-29/+29
| | | | | | | | | | This makes the wav and pcm demuxer demux bigger packets, which is more efficient. As a side effect of the bigger packets, audio durations can become less exact for command lines such as "ffmpeg -i $INPUT -c:a copy -t 1.0 $OUTPUT". Signed-off-by: Marton Balint <[email protected]>
* avformat/riffenc: don't force WAVEFORMATEXTENSIBLE for flt/dbl LPCMGyan Doshi2023-12-282-4/+4
| | | | | | | | | | | | 2c2a167ca7 forced WAVEFORMATEXTENSIBLE for all LPCM streams with greater than 16 bits per sample. However, WAVEFORMATEX allows IEEE Float samples or any depth where raw depth == coded depth, see Remarks section at https://learn.microsoft.com/en-us/windows/win32/api/mmreg/ns-mmreg-waveformatex and samples M1F1-float32-AFsp, M1F1-float64-AFsp at https://www.mmsp.ece.mcgill.ca/Documents/AudioFormats/WAVE/Samples.html There are hardware devices and likely software players requiring float samples that fail to qualify files with WAVEFORMATEXTENSIBLE headers.
* fftools/ffmpeg: propagate frame durations to packets when encodingAnton Khirnov2023-04-199-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove now-obsolete code setting packet durations pre-muxing for CFR encoded video. Changes output in the following FATE tests: * numerous adpcm tests * ffmpeg-filter_complex_audio * lavf-asf * lavf-mkv * lavf-mkv_attachment * matroska-encoding-delay All of these change due to the fact that the output duration is now the actual input data duration and does not include padding added by the encoder. * apng-osample: less wrong packet durations are now passed to the muxer. They are not entirely correct, because the first frame duration should be 3 rather than 2. This is caused by the vsync code and should be addressed later, but this change is a step in the right direction. * tscc2-mov: last output frame has a duration of 11 rather than 1 - this corresponds to the duration actually returned by the demuxer. * film-cvid: video frame durations are now 2 rather than 1 - this corresponds to durations actually returned by the demuxer and matches the timestamps. * mpeg2-ticket6677: durations of some video frames are now 2 rather than 1 - this matches the timestamps.

* avformat/mpegtsenc: get rid of packet counting for sdt/pat/pmtMarton Balint2019-08-231-2/+2
| | | | | | | | | | | | | The packet counting based approach caused excessive sdt/pat/pmt for VBR, so let's use a timestamp based approach instead similar to how we emit PCRs. SDT/PAT/PMT period should be consistent for both VBR and CBR from now on. Also change the type of sdt_period and pat_period to AV_OPT_TYPE_DURATION so no floating point math is necessary.

* | adpcm: Write the proper predictor in trellis mode in IMA QTMartin Storsjö2014-06-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The actual predictor value, set by the trellis code, never was written back into the variable that was written into the block header. This was accidentally removed in b304244b. This significantly improves the audio quality of the trellis case, which was plain broken since b304244b. Encoding IMA QT with trellis still actually gives a slightly worse quality than without trellis, since the trellis encoder doesn't use the exact same way of rounding as in adpcm_ima_qt_compress_sample and adpcm_ima_qt_expand_nibble.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Partially undoes commit 2c4e08d89327595f7f4be57dda4b3775e1198d5e: riff: always generate a proper WAVEFORMATEX structure in ff_put_wav_header A new flag, FF_PUT_WAV_HEADER_FORCE_WAVEFORMATEX, is added to force the use of WAVEFORMATEX rather than PCMWAVEFORMAT even for PCM codecs. This flag is used in the Matroska muxer (the cause of the original change) and in the ASF muxer, because the specifications for these formats indicate explicitly that WAVEFORMATEX should be used. Muxers for other formats will return to the original behavior of writing PCMWAVEFORMAT when writing a header for raw PCM. In particular, this causes raw PCM in WAV to generate the canonical 44-byte header expected by some tools. Signed-off-by: Michael Niedermayer <[email protected]>
