<br /> I get the impression it's a buggy stream; or perhaps the 'anomaly checker' has got activated?</blockquote>
<br /> <span>Hmmm... could it be my frontend (kodi)?</span><br /> <br /> <span>'anomaly checker' never heard of that?</span></blockquote>
<br /> I thought that might be a compiler option. Your error is in the backend log, so kodi seems an unlikely suspect - but I thought this was a decoding issue, which sounds more frontend-ish<br /> <br /> It apparently got into myth in one of jya's big ffmpeg commits, 18 months ago:<br /> <br /> <span><a href="https://lists.gt.net/mythtv/firehose/594425">https://lists.gt.net/mythtv/firehose/594425</a></span><br /> <br /> <span>golomb: always check for invalid UE golomb codes in get_ue_golomb</span></blockquote>
<br /> <span>Ok, sounds right, but then again I am out of my deepth.</span><br /> <br /> <span>Looks like there is a patch?</span></blockquote>
<br /> I haven't seen one. I've just been trying to select stuff from google. But the only reference to get_ue_golomb that I find in the myth code, outside ffmpeg, is in<br /> <br /> <span>libs/libmythtv/mpeg/H264Parser.cpp</span><br /> <br /> <span>And there's external/FFmpeg/libavcodec/tests/golomb.c</span><br /> <br /> which looks as if it might be instructive if I knew how to point it at something.<br /> <br /> <span>Cheers,</span><br /> <br /> John<br /><br /></div>

<div>As far as I can see I have no issues with tunes, recording etc. and I would therefore suspect it is a bug.</div>

<div> </div>
<div>Do you think I can turn down the level of logging in mythtv - just to remove the "noise" it makes in my logging?</div>
