Hello,. when i enable conversion of DTS HD MA 7.1 to eac 7.1, channel's set to no downmix The log always shows this line: avwriter: hevc, #2:dca/7.1 -> eac3/mono/768kbps, ac3, And the output file gets mono track When i downsampled to 5.1, it worked fine

UPDATE:" tried again with FFmpeg and got: eac3, 48000 Hz, 5.0, So its also broken

Edit 2: Started using AAC codec for quality and file size, no issue,

I have the same issue, but it's with a TrueHD audio track as source

What are the raw commands being generated for those? (please exclude file names)

Need to see if this is error in FastFlix or if we need to see if the encoders themselves are having some issue.

This looks to be a limitation of their encoders. I tried to manually set 7.1 and got: 

[eac3 @ 000002545d219bc0] Specified channel layout '7.1' is not supported

So will need to add a way a limiter to only allow 5.1 as max for eac
