I want to ask if ffmpeg
supports VP9 encoding, and if not: how can I encode VP9 videos?
I try using the command:
./ffmpeg-vp9 -y -i /home/mc/test.mkv -t 00:00:30 -c:v libvpx-vp9 -strict -2 -quality good -b:v 600k -speed 16 -rc_lookahead 25 -pass 1 2.webm
but it shows an error in splitting the command appeared (for vp9
).
This is the output of ffmpeg -codecs | grep vpx
:
./ffmpeg -codecs|grep vpx

DEV.L. vp8 On2 VP8 (decoders: vp8 libvpx ) (encoders: libvpx )
I tried to use vpxenc
but i don't know the meaning of its parameters exactly.
Thanks in advance.
2out of curiosity, why on earth vp9? :-) – Fredrik Pihl – 2013-05-20T20:18:03.250
