thanx for the quick reply
I found the same, but would have expected more users to have the issue.
As I only updated mythtv, there maybe where some additional things to
update?
i.e. libavcodec
I get the impression it's a buggy stream; or perhaps the 'anomaly
checker' has got activated?
Hmmm... could it be my frontend (kodi)?
'anomaly checker' never heard of that?
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
It apparently got into myth in one of jya's big ffmpeg commits, 18
months ago:
https://lists.gt.net/mythtv/firehose/594425
golomb: always check for invalid UE golomb codes in get_ue_golomb
Ok, sounds right, but then again I am out of my deepth.
Looks like there is a patch?
