DVB-T2 Radio failing following e54b9b6fd6 / 3944ca9ad0

Reported by: Nigel Jewell Owned by: jpoet

Component: MythTV - Recording Version: 0.26-fixes
Severity: high Keywords: DVB Radio

Description

Since the latest round of fixes committed to 0.26-fixes on the 1st March I am finding that all radio recordings from a DVB-T2 tuner are failing. It manages to record < 1024 bytes, appears that it is continuing to record and finishes, but the file does not get any bigger.

Nigel, can you apply the attached debug patch, and then attach a log from trying to record one of these radio streams?

Thanks Nigel. Please test dtvrecorder-dont-buffer-audio-only.patch to see if it fixes the problem.

Hi John,

I pleased to say that with stock 0.26-fixes and your patch I am once again able to record radio without issue. Thanks for the quick turnaround.

Regards, Nige.

Hi John,

some weeks ago I cherry-picked myself 87a15e1c (DTVRecorder: buffer up each payload until we know if the payload is a keyframe) from master to fixes/0.26. After that I recognised that I couldn't hear to or record audio only channels (DVB-S radio) any more. So I applied the dtvrecorder-dont-buffer-audio-only.patch​ and radio worked again. So after you commited these patches to fixes/0.26 I decided today to revert my own changes and upgrade to stock fixes/0.26. But now radio again doesn't work any more. Please give me some advice what info from me now is needed to track down to the problem.

Regards Sascha
