Does anyone had success to use the FFMPEG Consumer to record a video including the alpha channel?
I tried the following:
- libx265 with yuva420p, the video is then simply recorded without alpha channel
- prores_* uses so much CPU, that is can barely handle more than 10 frames per second. I wanted to tune the speed settings but all passed private options are ignored (e.g.
- I tried to use
libvpxbut again I fail because I can’t set the private options from the coded (would need to set
-auto-alt-ref 0to support aloha channel)
Does anyone knows a successful combination of codec/options or someone knows how to pass private options to the FFmpeg consumer?
I’m using CasparCG 2.2
Thanks for the help,
