HW acceleration on Kaltura transcoding

Hello,

Has kaltura support hardware acceleration on transcoding ?

Hello,

Can you please be more specific? in general, Kaltura uses FFMPEG and, in the event of failure, Mencoder in order to perform transcoding. We make an attempt to utilize all the aforementioned project features to provide the best transcoding possible per source.

Thanks,

Hello,

Currently our installed kaltura transcode videos on CPU. I want to transcode videos on GPU with NVENC of NVIDIA. Is it possible to replace kaltura ffmpeg 0.6 and ffmpeg 2.1.3 with custom built ffmpeg which is supported NVENC of NVIDIA.

or is it possible to add NVENC support into pre-built ffmpeg that provided by kaltura ?

Hello,

Looking here: http://www.phoronix.com/scan.php?page=news_item&px=MTg0NTY I see this requires specific, none official branches of FFMPEG. It was never tested by us.
You can try to compile FFMPEG from parallel versions with this support and check how it behaves with the platform but I must say I don’t really recommend it and we will not be able to provide you with support on issues it may raise.

Thanks,
