[mythtv-users] transcoding not working in 0.12 (for me ;-)

[Joshua Goldenhar]

Hey all,

I had read that transcoding didn't work in 0.11 (rpm's) - that you lost
audio, so I never tried it.

I've since upgraded to the latest rpm's via apt-get and updated the
video DB - no problems with any of that.  Myth seems to be working as
well as before.

So I enabled the 'transcode in background' to make the mpeg2's (from my
PVR250) into smaller mpeg4's.

It doesn't work - I was seeing the "ivtv: Not enough free buffers,
stream 0" in the messages file, so I updated ivtv drivers to latest CVS
tarball from ivtv.sf.net.

I don't see the old message any more, but I do see these:

So the transcoding starts, creates a .tmp file for each recording it
attempts to transcode but fails - leaving a 130-180K .tmp file behind.

This is a redhat 9 system, apt-get maintained, 2.4 GHz Celeron with
512MB RAM.

Clues?
