[mythtv] regression with 7f00642b

[Piotr Oniszczuk]

Peter,
With this commit, many mplexes started to have following codec information:

May 10 16:44:31 mythtv mythbackend[7670]: TVRec[17]: TuningNewRecorder - CreateRecorder()
May 10 16:44:34 mythtv mythbackend[7670]: DTVRec[17]: Music Choice program detected
May 10 16:44:36 mythtv mythbackend[7670]: TVRec[17]: Changing from WatchingLiveTV to None
May 10 16:44:36 mythtv mythbackend[7670]: Finished Recording: Container: MPEG2-TS Video Codec: none (0x0 A/R: 0 25fps) Audio Codec: ac3
May 10 16:44:36 mythtv mythbackend[7670]: TVRec[17]: FinishedRecording(15457_2018-05-10T14:44:31Z) damaged recq:<RecordingQuality overall_score=„0"

pls look at video codec…

looking on recorder code, I see that ‚Music Choice program detected’ detection is based stream rate evaluating.
There is no video codec reported - I suspect recorded stream has filtered-out video part - so bit rate becomes v.low.
this low bitrate causes that dtvrecorder detects such stream as Music Choice program….

> If it says "Music choice program detected" that will not normally cause a failure. It indicates that there is a very slow frame rate. It does not treat those much differently, just uses increased timeout values, which should not cause a problem. Probably the "Music choice detected" is a symptom of something else happening.
