And with CUVID, in particular: It's decoders are very fragile. You did mention that disabling hwaccel (cuvid?) raised your processor load significantly, correct? Can you confirm whether you're applying any filters down the encoder pipeline? Also, what processor are you using? On 6 June 2018 at 1

In production, drop this: -hwaccel cuvid -c:v mpeg2_cuvid There's a reason mpv devs do not recommend cuvid, in particular. https://github.com/mpv-player/mpv/commit/dbef5b737e2f994f02923c8214cba368b663a655 On 5 June 2018 at 11:55, Mitja Pirih wrote: > Hi, > > I am transcoding a live channel fro

Hi, I am transcoding a live channel from live source. Everything works as expected until SAR/DAR changes then ffmpeg crashes out. It happens only when I use HW transcoding. Have you seen this behavior before? Any ideas how to solve this issue? /usr/bin/ffmpeg -hwaccel cuvid -c:v mpeg2_cuvid -i ud
