Hello, i'm trying to encode some bluray h264 remux to vp9 webm. Actually i'm using this line for encoding:
Code:
ffmpeg -i /Rambo.mkv -c:v libvpx-vp9 -b:v 1400 -threads 8 -speed 1 -c:a libopus -b:a 96 -f webm /Rambo.webm
Problem is that the original audio is "DTS Master Audio, English, 7.1 channels, 24 bits, 48kHz" and when i run this line, ffmpeg reports that will generate libopus in 5.1 and i want it in Stereo
I tried putting --downmix-stereo but it doesn't work "Unrecognized option '-downmix-stereo' appear, i need help to determine the parameter to encode DTS to Opus in Stereo.
Thanks!
