4.1.1163 vs 4.0.7 - Doubled CPU load on transcoding

Added by Marco Jakobs almost 9 years ago

Hi,

I've updated my mature stable 4.0.7 to 4.1.1163 as I've read that there are improvements in transcoding in the 4.2 alpha.

Unfortunately it seems it's the opposite: HD transcoding down to 2MBit for mobile access took around 150-180% CPU for the TVH process (6 VM cores assigned). With 4.1.1163 the same needs around 350%.

I know this is an alpha and things might be broken, but is this a known issue or does this need reporting?

I'd log it as a problem - to my knowledge, the transcoding code hasn't changed, so something else must be in play. It's possibly an ffmpeg issue, I suppose, but could be something else.

I've not seen anyone else mention it.

Nah, it was definitely nothing else running but this single transcoding ...
