Jan Ekström	453b2f3c15	ffmpeg: add a data size threshold for muxing queue size This way the old max queue size limit based behavior for streams where each individual packet is large is kept, while for smaller streams more packets can be buffered (current default is at 50 megabytes per stream). For some explanation, by default ffmpeg copies packets from before the appointed seek point/start time and puts them into the local muxing queue. Before, it getting utilized was much less likely since as soon as the filter chain was initialized, the encoder (and thus output stream) was also initialized. Now, since we will be pushing the encoder initialization to when the first AVFrame is decoded and filtered - which only happens after the exact seek point is hit as packets are ignored until then - this queue will be seeing much more usage. In more layman's terms, this attempts to fix cases such as where: - seek point ends up being 5 seconds before requested time. - audio is set to copy, and thus immediately begins filling the muxing queue. - video is being encoded, and thus all received packets are skipped until the requested time is hit.	4 years ago

Lynne	45070eec4c	libwavpackenc: remove libwavpackenc wrapper The manual states "there is virtually no reason to use that encoder.". It supports less sample formats than the native encoder, is less efficient than the native encoder and is also slower and pretty much remains untested. libwavpack also isn't being fuzzed, which given that we plug the parameters without any sanitizing them looks concerning.	4 years ago
Anton Khirnov	68918d3b7f	lavu/buffer: add a convenience function for replacing buffers A common pattern e.g. in libavcodec is replacing/updating buffer references: unref old one, ref new one. This function allows simplifying such code and avoiding unnecessary refs+unrefs if the references are already equivalent.	4 years ago

Nicolas George	ddba05afe4	lavfi/vsrc_testsrc: switch to activate. Allow to set the EOF timestamp. Also: doc/filters/testsrc*: specify the rounding of the duration option. The changes in the ref files are right. For filter-fps-down, the graph is testsrc2=r=7:d=3.5,fps=3. 3.5=24.5/7, so the EOF of testsrc2 will have PTS 25/7. 25/7=(10+5/7)/3, so the EOF PTS for fps should be 11/7, and the output should contain a frame at PTS 10. For filter-fps-up, the graph is testsrc2=r=3:d=2,fps=7, for filter-fps-up-round-down and filter-fps-up-round-up it is the same with explicit rounding options. But there is no rounding: testsrc2 produces exactly 6 frames and 2 seconds, fps converts it into exactly 14 frames. The tests should probably be adjusted to restore them to a useful coverage.	4 years ago
