• ffmpeg vaapi hardware acceleration with some videos not working

  15 juillet 2020, par Maisen1886

  I have a problem with transcoding various videos on my Synology NAS. Some videos work, some do not.

  


  ffmpeg command :

  


  sudo /volume1/@appstore/VideoStation/bin/ffmpeg -y -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i '/path/to/my/video/IMG_8647.MOV' -vf hwupload,scale_vaapi=w=640:h=-1:format=nv12 -c:v h264_vaapi -b:v 2M -movflags +faststart 'path/to/output4.mp4'


  


  After i enter the command above, i get following error output :

  Unfortunately I do not know that much about transcoding videos. Does anyone know what the problem here could be ?

  


  Without hardware support (without -hwaccel_output_format vaapi) it works.

  


  thanks a lot !

  


• FFMPEG for thumbnail from video distorted when downloaded

  17 juillet 2020, par bjacobs

  I am grabbing a thumbnail image from an mp4.

  


  When I use -c:v mjpeg, the thumbnail appears fine in the browser, but is completely distorted when I preview it on my Mac. If I use -c:v jpeg2000 the image looks fine on my Mac, but it does not show in the browser.

  


  Full command :

  


  ffmpeg -ss 3 -i https://some_site/some_video.mp4 -vf thumbnail,scale=480:480 -q:v 2 -frames:v 1 -f image2 -c:v jpeg2000 -r 1 -vframes 1 tmp/my_thumbnail.jpg

  


  -vs-

  


  ffmpeg -ss 3 -i https://some_site/some_video.mp4 -vf thumbnail,scale=480:480 -q:v 2 -frames:v 1 -f image2 -c:v mjpeg -r 1 -vframes 1 tmp/my_thumbnail.jpg

  


  What encoding do I need to use in order for the generated thumbnail to both be viewable in the browser and also preview-able on Mac ?

  


  This is what the distorted image looks like :


  


  I'm beginning to think this is an macOS issue, but even if it is, I'd like to know if FFMPEG would have a solution for it so that even users with the buggy OS can properly preview the image.

  


  Output :
