We already had the WMV vs Quicktime vs Real fiasco in the early 2000s, and we'd all had enough. H.264 was the format, with a short interlude by On2 VP6 FLV. The ship had sailed, and Youtube was a latecomer. They got to the party at 5 a.m., after everybody had gone home. Since 4K hasn't happened yet, VP9 has a chance.
h.264는 국제 표준화기구인 itu-t와 iso에서 공동으로 제안한 차세대 동영상 압축기술로 대개 h.264/avc 혹은 avc/h.264, h.264/mpeg-4 avc, mpeg-4/h.264 avc라고 불린다. MPEG4에 비해 40% 정도, MPEG2에 비해 60% 이상 전송속도가 빠르다.
Jun 07, 2020 · So it can contain Mpeg4, H264, x264, XAVC, VP9 (YouTube codec), H265 and even Mpeg2 (super logical, we agree …). That’s why so many people get confused with codecs! MP4 is widely used, but unfortunately it is not supported everywhere.
In the table below you can view which audio, video, and file formats the K-Lite Codec Pack supports. As you can see, even the smallest pack already supports playback of almost everything! The difference between the packs lies mostly in the included tools.

I encoded a source video with the different encoders, and then computed the PSNR value from ffmpeg ( ffmpeg -i P4160098.x265_crf26.mkv -i P4160098.MOV -lavfi psnr="stats_file=psnr.log" -f null - )
Jun 17, 2013 · H.264/MPEG-4 AVC (MP4) HEVC (MP4) VP8 (WebM) VP9 (WebM) AV1 (WebM) Android browsers Chromium: Depends on the build Google Chrome Microsoft Edge (Modern Chromium based versions) Only if hardware decoding is available Falkon: Mozilla Firefox: if ffmpeg supports it Safari (macOS/iOS) only for WebRTC GNOME Web: if gstreamer codecs are present
Also if/when Google stops supporting h.264 on Youtube in favour of webm (they say they are still going through with it, though personally I think it very much depends on webm becoming the official HTML5 video codec) you will need VP8/VP9 to watch the content.
VP9 is an open and royalty-free video coding format developed by Google. VP9 codec was developed with the intention of reducing bit rate by 50% compared to VP8, while having the same video quality. The VP9 video codec is supported on Mozilla, and Google’s Chrome browser.
