Video Codecs. The H.264 codec is a very flexible codec for efficient video encoding. It comes in a number of profiles which can accommodate different capabilities when it comes to color bit-depth, chroma sub-sampling, resolution, and intra or inter-frame compression. The H.265 / HEVC codec is even more efficient, at the cost of higher complexity. Codecs are also the fodder of lots of technical debate, arguments and not enough alcohol consumption (in my opinion). With WebRTC, Google decided to initially use a codec called VP8. The alternative was H.264. Like shark’s teeth, there are always new codecs such as AV1, VP9, and H.265 emerging.

This may be useful because there are lots of devices on the market which support H264 hardware decoding and do not support VP8/VP9. This extension has new features such as manual blocking of H264, VP8, VP9, AV1 codecs and 60fps video. By default it blocks everything but H264 and 60fps video. It works only on YouTube. From a quality perspective, the two codecs are very close, as they are in playback CPU, though VP9 does seem to have clear advantage in encoding efficiency. Overall, as with H.264 and VP8, it appears that the winner or loser between HEVC and VP9 will be selected by the politics of the situation, not based upon pure codec quality and performance. "FFV1" stands for "FF video codec 1" and is a lossless video codec, on arithmetic- and entropy-coding algorithms. The arithmetic coder of FFV1 is very similar to (and based on) that of H.264. FFV1 is implemented as part of the free, open-source libraries of the project FFmpeg . In a subjective quality comparison conducted in 2014 featuring the reference encoders for HEVC (HM 15.0), MPEG-4 AVC/H.264 (JM 18.6), and VP9 (libvpx 1.2.0 with preliminary VP9 support), VP9, like H.264, required about two times the bitrate to reach video quality comparable to HEVC, while with synthetic imagery VP9 was close to HEVC.
