[mythtv-users] Mythtranscode TRASHES file to 123KB when re-encoding with cut list

Mon May 23 20:13:00 UTC 2011

I automatically run mythtranscode on all my new recordings (all are
originally OTA mpeg2 in HD or SD) to convert them to mpeg4.

Then after watching them, I manually create a cut list to eliminate
commercials and other unwanted stuff. Then I re-run mythtranscode
manually from within mythfrontend.

This always worked until just now when I notice that a 725MB file was
reduced to about 123KB (when I was just cutting about 5%). I tried
again just to make sure I hadn't mistakenly cut the whole file and the
same thing happened again.

I am running myth-0.24 fixes.
The only "new" thing is that I recently updated to include the
backported fix for the mythtranscode 6-channel audio problem though I
wouldn't think this would effect my problem (and the channel I am
dealing with is not 6-channels since it transcoded fine the first time
before the fix).

The only potentially unusual lines in the log are:
1] "Found video height of 1088.  This is unusual and more than likely
   the video is actually 1080 so mythtranscode will treat it as such."

2] "SampleRate: Attempted to add a rate 32000 Hz, which is not in the
   list of allowed rates." 
However, both of these messages have occurred before and never were an
issue (actually #2 always occurs)

Here is the full text of the relevant log:
