Hi folks,
Since updating my Ubuntu box and also the MythTV version that comes with
it to version 31, I've noticed a problem with mythcommflag sometimes not
completing.
The recording in question is one where the schedule is set up to end
recording early. (i.e. a negative "End Late" value).
Before the upgrade, this worked OK other than some aspects of mythtv
thinking that the recording was still going on despite it having ended
early. I think it was the entry in MythWeb that still showed it as
recording if memory serves me correctly.
Anyway, now that I've updated things, I've noticed that mythcommflag
shows as still running in MythWeb without making any progress. And sure
enough, there's a mythcommflag process still running for the recording
in question, without it making any progress.
Looking at the log file, I see entries for the problematic show like:
mythcommflag[1168394]: I CoreContext ClassicCommDetector.cpp:372 (go)
Finding Logo
mythcommflag[1168394]: I CoreContext ClassicCommDetector.cpp:550 (go) 0%
Completed @ 133.156 fps.
mythcommflag[1168394]: I CoreContext ClassicCommDetector.cpp:550 (go)
10% Completed @ 115.144 fps.
mythcommflag[1168394]: I CoreContext ClassicCommDetector.cpp:550 (go)
20% Completed @ 65.368 fps.
mythcommflag[1168394]: E Decoder mythplayer.cpp:3358 (DecoderGetFrame)
Player(0): Decoder timed out waiting for free video buffers.
At this point, mythcommflag is completely stuck, never to complete. If
I watch the show in MythTV, it shows up as no commercials flagged at all.
Now, if I run mythcomflag (with either the file or the channel +
starrtime option) manually from a command prompt it goes all the way to
100%. Granted it reports an "End of file" error at the end and an exit
code of 6, but the commercials are successfully flagged, and MythTV
shows this.
Does anybody know what might be going on here? Or how I may be able to
address it in a non-hacky way?
As an aside, now that I'm looking at the mythcommflag logs, I'm seeing
that it's reporting "VDPAUHelp: VDPAU is NOT available" "VAAPIDec: VAAPI
functionality checked failed" and "NVDEC: No NVDEC decoders found",
eventually falling back to ffmpeg. In the process of configuring
MythFrontend, I know that at least VDPAU and NVDEC are indeed both
available, at least to the mythfrontend process. Is this expected
behavior? I'd think that mythcommflag using something other than ffmpeg
for video decoding would result in better performance, no?
Thanks
