> I'm surprised to hear that you have buffer overruns in this case as your recording scenario (uncompressed with no concurrent qctools reporting) seems about as simple as feasible. Yes...

mmm.. I've also noticed there's a gradual but significant delay in the vrecord display and this increases until the buffer underruns occur. As a test at the moment, 53 minutes...

Disk Speed Test is what I'd expect on one of my injest drives: 

Upgraded to vrecord 2018-07-03 and still getting buffer overruns after around 30 mins of recording... Going to revert to an earlier version to test...

Yes, same behaviour with 2018-07-03 I've just reverted to 2018-05-14 and this resolved the issue - I managed to get through 60 minutes of uncompressed recording with no buffer overruns..

Hi @dericed - no all the issues have been when using component inputs and analogue audio, although I haven't tested to check the digital inputs yet.. Using ffmpeg 4.0.1 at...
