Very interesting. I don't think this patch is the proper fix though. There never should be an active cuda context when returning from a function, at least that's the premise under which I wrote all cuda related functions so far. This must mean that before, cuvid or something else must somehow have leaked a bound cuda context to nvenc. So that might need fixing as well. Thank you very much for finding this! _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
