[mythtv-users] MPEG2->MPEG4 transcoding under .12

[Ellen Spertus]

I have a RH9 PVR-350 system and upgraded to .12 today via sources.  I
can't get working auto-transcoding from MPEG2 (done in hardware by the
PVR-350) to MPEG4.  Specifically, I get the error "Illegal profile :
autodetect".  Here are the relevant lines from mythbackend.log file
(with verbose logging enabled):

The last line of the log file suggests that the problem is with
profiles.  I'm using the default profile settings.  The only change I
may have made is enabling auto-transcoding.  Specifically, the relevant
parts of the relevant profiles are:

Group: MPEG-2 Encoders (PVR-250, PVR-350)
Profile: Default
- Auto transcoding enabled
- Codec: MPEG-2 Hardware Encoder
  - Stream Type: MPEG2-PS
  - Aspect Ratio: 4:3
  - Bitrate: 4500
  - Max Bitrate: 6000

Group: Transcoders
Profile: RTjpeg/MPEG4
- Auto transcoding enabled
- Codec: MPEG-4

The recording works correctly, and I have confirmed that it is in MPEG-2
format.  Any suggestions of what I should do to get transcoding to
MPEG-4 working?

Thank you.
