Crash in AVC encoding pass 1
#8
Quote:One odd thing, so far when using Hybrid I have generally seen the audio processing and file swapping etc tends to be either single threaded or IO-bound, so the CPU is running at 25-50% utilisation in those phases, but the video encoding passes (with the default "0 threads" setting to use the default threading) are entirely CPU bound, so the CPU sits nailed at 100% for 1-2 hours for a full feature film.
Nothing odd about it. Audio compression generally doesn't really use multithreading.

Quote:Running the pipeline for this DVD rip, with more filters involved, the CPU only seemed to reach about 50% utilisation. Obviously with more filtering you'd expect a longer processing time, but I wondered whether there were also some changes I should be making to the threading configuration to get the best throughput?
Some filters are slow others are fast, I doubt that tweaking the threading settings will change much.

As genera hint:
Do not use the ffmpeg filters. Anything that can be done with those filters can be (better) done with Avisynth/Vapoursynth.

Quote:If there are any good guides to the options available that would be good to know.
Nope. Avisynth and Vapoursynth filters have their own Preview which normally helps checking out the effect of the filters.
