On the part of the new options added to the ffmpeg utility, the inclusion of -shortest_buf_duration to set the maximum duration of buffered frames (The more, the higher the accuracy in "-shortest" mode, but higher memory consumption and latency).Īnother added option is -stats_enc_pre, -stats_enc_post and -stats_mux_pre to write frame-by-frame information about selected streams in the specified file at different stages of encoding. We can also find in this new version, the implemented support for VAAPI and QSV (Quick Sync Video) to encode and decode VP9 and HEVC with 4:2:2 and 4:4:4 color subsampling, 10-bit and 12-bit color depth encoding.Īnother novelty that is presented is that added support for oneVPL library (oneAPI Video Processing Library) to use Intel QSV (Quick Sync Video) hardware acceleration technology, as well as QSV-based hardware accelerated AV1 encoder added.
