[mythtv-users] Transcode breakage in MythTV 0.35

I have been transcoding video files for years, always using  "autodetect" .

Upgrading Fedora yesterday meant upgrading MythTV, and now transcoding
is broken.

The error is the same every time:

 CoreContext transcode.cpp:174:TranscodeFile  AVFormat mode not set.

It appears mythtranscode needs another flag.  When I ran it manually
with --infile (to fix the result of transcoding from h264 to mpeg2), I
found that adding a "-m" to the command line made it work.

What do I have to do with a transcoding profile to make it work from MythTV?
