[mythtv-users] DVBRead mpeg/mpegstreamdata.cpp:362 (AssemblePSIP) Error: offset>181, pes length & current cannot be queried

[Brian J. Murrell]

Running 0.25-fixes, I was doing a 3 program multirec last night on an
HVR-950Q and all three recordings just stopped suddenly.  During the
window of the recordings (1 @ 20:00 and 2 @ 20:30 all ending at 21:00)
the backend log reports:

Apr 18 20:01:18 pvr mythbackend[1857]: I ProcessRequest recorderbase.cpp:386 (GetKeyframePositions) RecBase(2:/dev/dvb/adapter0/frontend0): GetKeyframePositions(1813,9223372036854775807,#10) out of 93
Apr 18 20:01:18 pvr mythbackend[1857]: I ProcessRequest recorderbase.cpp:386 (GetKeyframePositions) RecBase(6:/dev/dvb/adapter1/frontend0): GetKeyframePositions(1936,9223372036854775807,#3) out of 133

And similar:

Apr 18 20:30:32 pvr mythbackend[1857]: I ProcessRequest recorderbase.cpp:386 (GetKeyframePositions) 
RecBase(3:/dev/dvb/adapter0/frontend0): GetKeyframePositions(634,9223372036854775807,#21) out of 72
Apr 18 20:30:32 pvr mythbackend[1857]: I ProcessRequest recorderbase.cpp:386 (GetKeyframePositions) RecBase(1:/dev/dvb/adapter0/frontend0): GetKeyframePositions(808,9223372036854775807,#4) out of 73

And then this:

Apr 18 20:32:04 pvr mythbackend[1857]: E DVBRead mpeg/mpegstreamdata.cpp:362 (AssemblePSIP) Error: offset>181, pes length & current cannot be queried

At the end of the recording the following messages were reported:

Apr 18 20:59:59 pvr mythbackend[1857]: I TVRecEvent tv_rec.cpp:812 (FinishedRecording) TVRec(2): FinishedRecording(2917_2012-04-18T20:00:00) damaged recq:<RecordingQuality overall_score="0" key="2917_2012-04-18T20:00:00" countinuity_error_count="0" packet_count="3257088">#012    <Gap start="2012-04-18T20:32:03" end="2012-04-18T21:00:00" duration="1677" />#012</RecordingQuality>

Apr 18 20:59:59 pvr mythbackend[1857]: I TVRecEvent tv_rec.cpp:812 (FinishedRecording) TVRec(1): FinishedRecording(4097_2012-04-18T20:30:00) damaged recq:<RecordingQuality overall_score="0" key="4097_2012-04-18T20:30:00" countinuity_error_count="0" packet_count="228902">#012    <Gap start="2012-04-18T20:32:01" end="2012-04-18T21:00:00" duration="1679" />#012</RecordingQuality>

Notice that all three of those report a RecordingQuality that includes
a "Gap" that starts at 20:32:01-03 which is within a second or two of
the above "AssemblePSIP" error.

Additionally, the following is logged at the end of those three
recordings:

Apr 18 20:59:59 pvr mythbackend[1857]: W DeviceReadBuffer DeviceReadBuffer.cpp:525 (Poll) DevRdB(/dev/dvb/adapter0/frontend0): Poll took an unusually long time 1674946 ms

There is nothing in my kernel log buffer during that window other than
a firmware load for the HVR-950Q device.

Any ideas what happened at 20:32:04?

Cheers,
b.
