[FFmpeg-user] Crash on DAR/SAR source change while HW transcoding

[Dennis Mungai]

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?
