This option is enabled by +default as most video and all audio filters cannot handle deviation in input frame properties. +Upon reinitialization, existing filter state is lost, like e.g. the frame count @code{n} +reference available in some filters. Any frames buffered at time of reinitialization are lost. +The properties where a change triggers reinitialization are, +for video, frame resolution or pixel format; +for audio, sample format, sample rate, channel count or channel layout. + @item -filter_threads @var{nb_threads} (@emph{global}) Defines how many threads are used to process a filter pipeline. Each pipeline will produce a thread pool with this many threads available for parallel processing. _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
