seems like the codecs='something' is REALLY nitpicky. managed to get a test video to play with:
I made the video by encoding some random clip with
ffmpeg -i random_video.mp4 -c:v libaom-av1 -crf 30 test.mp4
(seems to work just as well withlibsvtav1
)As for how are you supposed to know the "4d401f"? beats me, found it here: https://caraya.github.io/av1-video-demo/
edit: https://developer.mozilla.org/en-US/docs/Web/Media/Formats/codecs_parameter#av1 does say that the codec string should look a bit different, but... I dunno, not a video-understanding-webmonke.
edit2: and now I realize that since it works with the codecs=avc1 - it's the older av1 variant? Not really what you were asking. Whoopsiedaisy.
avc1 is the name for H.264 (also called AVC) which is admittedly pretty confusing
Thanks @[email protected] ,
by any change I've tried
codecs="avc1.4d401f"
with my videos but of course it's not working.Whats drive me crazy, is when open trough
file:///
Firefox can play it, but once inside an html page, you have to specify the right codec !? WTFand you're absolutely sure the files are av1? if you try to open the video files with ffmpeg, eg:
ffmpeg -i videofile.mkv
, what does it say the codec is?at least my av1 videos say:
Stream #0:0[0x1](und): Video: av1 (libdav1d) (Main) (av01 / 0x31307661), yuv420p(tv, progressive), 854x854, 464 kb/s, SAR 1:1 DAR 1:1, 30 fps, 30 tbr, 16k tbn (default)
ffmpeg -i FooBar.mkv
