[FFmpeg-user] Not using all resources

[Henk D. Schoneveld]

Hi all,

I’m encoding from several DVB-S sources, satellite, with always the same parameters but recordings from some sources CPU-load is about 50% of what it could be, others use max. available as attachments show.

The 1st inserts a srt file while the 2nd doesn’t but because there’s no IO-bottleneck that should be a problem I think.
 
Any idea what could be the cause of it ? It’s not really problematic, just curious.
