* avformat/pcm: decrease target audio frame per sec to 10Marton Balint2024-03-161-1/+1
| | | | | | | | | | 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 <cus@passwd.hu>

* avformat/pcm: factorize and improve determining the default packet sizeMarton Balint2024-03-162-12/+30
| | | | | | | | | | | | | | - Remove the 1024 cap on the number of samples, for high sample rate audio it was suboptimal, calculate the low neighbour power of two for the number of samples (audio blocks) instead. - Make the function work correctly also for non-pcm codecs by using the stream bitrate to estimate the target packet size. A previous version of this patch used av_get_audio_frame_duration2() the estimate the desired packet size, but for some codecs that returns the duration of a single audio frame regardless of frame_bytes. - Fallback to 4096/block_align*block_align if bitrate is not available.

* avformat/fifo_test: Move into tests/fifo_muxer.cAndreas Rheinhardt2024-03-125-160/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This muxer solely exists to test the fifo muxer via a dedicated test tool in libavformat/tests/fifo_muxer.c. It fulfills no other role and it is only designed with this role in mind. The latter can be seen in two facts: The muxer uses printf for logging and it simply presumes the packets' data to contain a FailingMuxerPacketData (a struct duplicated in fifo_test.c and tests/fifo_muxer.c.); in particular, it presumes packets to have data at all, but this need not be true with side-data only packets and a segfault can easily be triggered by e.g. encoding flac (our native encoder sends a side-data only packet with updated extradata at the end of encoding). This patch fixes this by moving the test muxer into the fifo test tool, making it inaccessible via the API (and actually removing it from libavformat.so and libavformat.a). While this muxer was accessible via e.g. av_guess_format(), it was not really usable for an API user as FailingMuxerPacketData was not public. Therefore this is not considered a breaking change. In order to continue to use the test muxer in the test tool, the ordinary fifo muxer had to be overridden: fifo_muxer.c includes lavf/fifo.c but with FIFO_TEST defined which makes it support the fifo_test muxer. This is possible because test tools are always linked statically to their respective library.

In the documentation section, point #2 was wrong: ccextractor extracts the Closed Captions data and stores normalized bits similarly to this muxer. Signed-off-by: Marth64 <marth64@proxyid.net>
