FFMPEG 100% when transcoding DTS

[Paul]

Hi Derek,

Who's Derek?

Applied those changes, but same problem - 100% CPU with that VC-1 file.

I tried a different movie - remuxed H264 + dts in a MKV and it played perfectly. Around 5-8%CPU transcoding the audio only.

So there's no way we can passthrough the VC-1 stream completely and just transcode the audio??

Yes, as I said, FFmpeg cannot encode VC1 at the moment, thus they cannot be remuxed like h264. Hopefully a future build of FFmpeg will allow encoding VC1 - we are constantly building new FFmpeg's to see what has changed and Mezzmo updates always come with the latest build.
