MJPEG hardware encoding on notebook?

[marcorocchini]

Hi ca*s,

please I wonder if there is a way to do an hardware MJPEG encoding (to improove the speed) also using a special GPU on laptop pc's?

thanks

NVidia should support mjpeg, other GPU's proably also (if they support MPEG-2 then i see no technical issues to support MJPEG).
Perhaps Intra MPEG-2 or Intra H.264 will be ok for you?

mm mpeg-2 or other really not, I try to encode in mjpeg at the fastest way possibile so that I try to understand if is there a way to do an hardware encoding

Try PicVideo's MJPEG encoder. I get about 160 fps (i5 2500K) out of if when encoding 1920x1080p -- but I'm limited by reading the source. It supports YUV 4:4:4, 4:2:2 and 4:1:1, and interlaced encoding.

MPEG-2 Intra (or H.264 Intra) are comparable or better (for example significantly better defined and standardized) than MJPEG - they should be very fast (same or faster than MJPEG - HW).

I know cat but my dino-NLE can manage only mjpeg

Sky Lake and Kaby Lake Quick Sync both support hardware MJPEG encoding.

Sky Lake and Kaby Lake Quick Sync both support hardware MJPEG encoding.

And it should be accessible through ffmpeg /avconv through vaapi if configured with support

ah thanks but support: 4:2:2?

4:2:0 for vaapi

MJPEG

The MJPEG encoder only accepts YUV 4:2:0 surfaces and encodes them as baseline DCT using the standard quantisation and huffman tables. The one usable option is global_quality, which sets JPEG quality (to scale the standard quantisation tables) in the range 1-100.

so there is not a way to get hardware encoding in 4:2:2?
