Server Version#: Version 1.15.1.710 Player Version#: Latest as of 2/2018 I recently upgraded to a QNAP TS-453 2018 Model. It works great except i have notice thumbnail generation is hilariously slow. Not bad for keeping up to date, but can be days if a new show is added. I understand that this i…

[image] Jumbs: Does thumbnail generation not use the hardware decoding? Nope [image] Jumbs: If not, is that a bug or expected result? WAD, aka Working as designed When said, it’s a good idea, so re-tagged your port to Feature Suggestions and voted for it :wink:

Thanks! At least i know why now.

Remember to vote as well :wink:

Voted. In my very uninformed guess, i assume since the transcoding works using HW, it shouldn’t be a major implementation.

[image] Jumbs: it shouldn’t be a major implementation. I sadly disagree here, since there’s so many platforms to consider, as well as all the different HW used. It’s very complicated

[image] Jumbs: QNAP TS-453 2018 Ok. Well make it work for the QNAP TS-453be 2018 first then…

Could it be possible to use the VAAPI MJPEG encoder combined with the qsv filters for Intel GPUs at least? NVENC also has an MJPEG encoder. Even if you had to do it in 2 passes, first pass to encode the resized and 0.5 fps mjpeg file, and then extract all frames from that to build the bif file. Is t…

ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mkv -r 1/2 -c:v mjpeg_vaapi -vf 'scale_vaapi=w=320:h=-1:format=nv12' -global_quality 90 -f image2 img-%06d.jpg This works on my Xeon E3-1245V6 using Linux with ffmpeg 4.0.4 with very little CPU usage.

Ill take any system that speeds it up!
