<br /> I get the impression it's a buggy stream; or perhaps the 'anomaly checker' has got activated?</blockquote>
<br /> <span style="white-space: nowrap;">Hmmm... could it be my frontend (kodi)?</span><br /> <br /> <span style="white-space: nowrap;">'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 style="white-space: nowrap;"><a href="https://lists.gt.net/mythtv/firehose/594425">https://lists.gt.net/mythtv/firehose/594425</a></span><br /> <br /> <span style="white-space: nowrap;">golomb: always check for invalid UE golomb codes in get_ue_golomb</span></div>

<p>Ok, sounds right, but then again I am out of my deepth.</p>
<p>Looks like there is a patch?</p>
