You can check decoder details such as ffmpeg -h decoder=h264. Choosing a decoderAV1 is the replacement project that supplanted Google's VP10 and is specifically designed for real-time applications and higher resolutions than those typically supported by H.264 or VP9.

AV1 is an open source & royalty-free video codec developed by the Alliance for Open Media (AOMedia), a non-profit industry consortium. Depending on the use case, AV1 can achieve about 30% higher compression efficiency than VP9, and about 50% higher efficiency than H.264. There are currently three AV1 encoders supported by FFmpeg: libaom (invoked with libaom-av1 in FFmpeg), SVT-AV1 ( libsvtav1 ), and rav1e ( librav1e ).Nov 11, 2020 · With NVIDIA's recently released RTX 30 series there is initial support for hardware-accelerated AV1 decoding. Merged today is now support in FFmpeg for making use of this hardware AV1 decode with RTX 30 via NVIDIA's "NVDEC" decode interface that is part of their Video Codec SDK. The commit adds just under 400 lines of code to the FFmpeg ... A codec is the logic to encoding or decoding a media stream, there are many different types with popular ones being H.264, HEVC (H.265) and MPEG-4.. Codecs are different to containers like MP4, MKV and MOV because a codec manages the bitrate, resolution and frames whilst the container organizes and returns the data as sequence.Nov 04, 2020 · The FFmpeg patch we talked about back in September has now been merged for allowing AV1 decode over the VA-API interface with this widely-used multimedia library.
