[FFmpeg-user] After disabling Dolby codecs, no conversion to MP4 possible

[Takashi]

Hi,

I have disabled Dolby codecs in the ffmpeg configuration statement due
to licensing issues.

Now I can't convert to MP4 anymore. (I have this setup for a while now
and it seems to be a regression, as far as I can remember, it worked
before).

Would you mind to help me find the needed settings?

The following command shows that I can't encode to MP4:

$ /opt/ffmpeg_no_dolby/bin/ffmpeg -formats | grep mp4
