softhddevice - Sender in 1920x1090 - VDR startet neu

Thanks for your answers! I now know lot more about the situation regarding VDPAU, NVDEC etc. which might come in handy in the future.

For the meantime though I solved the issue via a workaround without causing any real drawback in my opinion.

I knew softhddevice had command line arguments but not that one of them lets you disable the hardware decoder. I stumbled across that feature by accident and added the argument "-w no-hw-decoder" to try it out. That not only instantly solved the issue this topic is about but along the way improved FFWD, FRWD, slow motion and pause behaviour during 1080i playback. So it looks like the crash is caused by the Nvidia hardware decoding.

I expected that disabling the hardware decoder would also mean loosing the advanced Nvidia scaling & deinterlacing but luckily it did not apparently. CPU load of my AMD A8-7600 went from 5 - 8% to 11-15% which is fine for me. I did not yet measure how it affected power usage of the whole system but I guess GPU load might have gone down in exchange to the CPU increase. I wish I discovered this years ago since the whole thing feels much better than it did during my time with easyVDR 3.5 (no offense to easyVDR, it was just that with the included combination of software components the Nvidia GT220/VDPAU/softhddevice always had issues which were absent before with Gen2VDR 4 IIRC). But then I was still using an Athlon XII CPU so maybe with that CPU letting the GPU do the decoding was still needed, I don't know.

So unless I overlooked something major I can only recommend this workaround.

@villeneuve can you give me recording of you problem channel?

I'd try. How long should it be?

At least 5-10 minutes.

Ok, I've uploaded two samples from two different 1080i channels that are hit by this problem:

Sample from BBC One HD

Sample from Movistar Formula 1

I hope downloading works, the daily traffic is limited.

I downloaded.

But these recordings play beautifully with vdpau and this softhddevice.

You tried it?

Nvidia GT1030, Ubuntu 18.04.

Thanks for trying! Your GT1030 is a much more current GPU and therefor I don't think you're using the Nvidia legacy driver I need to use with my GT220 as I stated above. My uneducated guess is that's what makes difference.

GT220 => kein nvdec => kein softhddevice mit nvdec

Ja klar, aber um nvdec gings hier jetzt nicht und lnj verlinkte ja auch auf das normale softhddevice.

But vdpau must works.

Looks like this discussion is going nowhere. No problem for me though, since the workaround works perfectly and in the long term I'm looking forward to be able to get rid of the Nvidia crap anyway.

*EDIT* Mit den aktuellen und nackten Testversionen von MLD und yaVDR konnte ich das Problem nicht mehr reproduzieren. Unter MLD hab ich dann nach und nach auch meine üblichen Plugins installiert aber auch damit ist das Problem nicht mehr aufgetreten. Also entweder ist der Fehler tatsächlich behoben oder aber er taucht erst auf, wenn irgendetwas auf eine bestimmte Weise konfiguriert wird. Ggf. werde ich dann wieder berichten.
