Hi All,
We're seeing failures on our production instance in encoding certain
files. The failure is consistent and always happens at the encoding of
the presentation for the hold state preview. The log message looks as
follows:
2012-02-16 15:44:28 INFO (AbstractCmdlineEncoderEngine:233) -

and null
The error seems to happen when some or all of the presentation is the
epiphan capture card (seen when no source was connected). I can reliably
reproduce this with certain recordings on both our production and
development environments (separate admin/worker) but not my local build
(all in one). This, with the error "Operation not permitted" suggests
some kind of workflow/file repository error - the ffmpeg docs lean
towards this being 1 of the files doesn't exist. However this doesn't
explain its reproducibility with certain packages and not others.
So far I have verified:
1) The profile creates a valid working copy (i.e ffmpeg isn't encoding
to to 0b file)
2) the file doesn't exist at:
/data/matterhorn/workspace/mediapackage/eeaa4715-e6c5-444e-88eb-4c0835263a25/632f74bf-0dfe-4323-9a5a-ae6f44fbf619/Presentation.mp4
But I don't know if one expects it to be cleaned up after the failure ...
Any help in solving this is apreciated
David
