Only tangentially related to Emby but I think this forum will have people who know... I am beginning to transcode my media collection to HEVC (with audio copy, so Emby can't do this directly for me) and I know my i7-7500U will support multiple decode/encodes with ffmpeg but I cannot find any stated limits.
Mostly BluRay rips but there will be HD-DVD/DVD MPEG2 files as well.
Any experience of how many parallel transcodes my HD620 will handle and/or pointers to wider sources of benchmarks/info?
For now I'm just kicking off 4 transcodes in parallel and it seems to be coping.
