Marton Balint	44b2769619	avformat/pcm: decrease target audio frame per sec to 10 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".

Marton Balint	9c2c0c37f8	avformat/pcm: factorize and improve determining the default packet size - 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.

Martin Storsjö	3fcfde2cea	aviobuf: Increase the default SHORT_SEEK_THRESHOLD to 32 KB The previous threshold, 4 KB, maybe was reasonable when it was set (in 2010), but in today's settings and with typical network speeds and data sizes, it's pretty small. 32 KB probably is a more reasonable default now, regardless of input. This changes the test references for two seek tests. When using the normal seek function, which boils down to the lseek(2) function, a seek to an out of bounds position doesn't return an error, but that condition is only reported when doing the subsequent read (which returns EOF). When doing more seeks by fast forwarding, the fact that the seeked to destination is out of bounds is noticed and reported sooner in these cases.

Philipp M. Scholl	040b28aecc	avformat/pcm: decrease delay when reading PCM streams. Thanks for the discussion. Here's the next version, now with /25 and removed ff_log2(). The blocksize of the PCM decoder is hard-coded. This creates unnecessary delay when reading low-rate (<100Hz) streams. This creates issues when multiplexing multiple streams, since other inputs are only opened/read after a low-rate input block was completely read. This patch decreases the blocksize for low-rate inputs, so approximately a block is read every 40ms. This decreases the startup delay when multiplexing inputs with different rates.

Nicolas George	dd9555e94b	ffmpeg: remove obsolete workaround in trim insertion. The bug it was working seems to have been fixed. This change causes ffmpeg to use the trim filter to implement the -t option. FATE tests are updated due to the more accurate handling of the last packets.	11 years ago
Anton Khirnov	a83c0da539	avconv: make -t insert trim/atrim filters. This makes -t sample-accurate for audio and will allow further simplication in the future. Most of the FATE changes are due to audio now being sample accurate. In some cases a video frame was incorrectly passed with the old code, while its was over the limit.	12 years ago
Janne Grunau	abab0435d4	fate: split dependencies for fate-seek tests Each fate-seek test depends now only on the corresponding fate-acodec, fate-vsynth2 or fate-lavf test which creates the file seek-tests operates on. The tests and references are renamed to match the test they depend on.	12 years ago
