Crash on playback #120

Open dnehring7 opened 6 years ago

dnehring7 commented 6 years ago

vdr crashes deterministically when starting a playback under the following circumstances:

the current channel is deinterlaced by vaapi (for me: motion-compensated). Instanty, after starting a playbay, vaapidevice crashes. If I disable deinterlacing, everything works. Attached is a backtrace and the system info:

Works for me, as far as it didn't crash instantly. Nevertheless the video isn't viewable most of the time (bad flicker / wrong sequence)

Maybe my (work-in-progress) patches will help...
