Allow the use of both the CPU and the GPU when generating Trickplay images - Bravo-Mike - 2024-05-16
I had an idea that could potentially speed up the generation of Trickplay images in a significant way:

I'd love to know your thoughts on the feasibility of this method and the effort required to implement it as an option.

My understanding is that the current process can use the GPU for decoding and CPU for encoding. Part/most of the reason it takes so long is that the entire file needs to be decoded. Based on some other observations, I believe that is a limitation of ffmpeg and not of Jellyfin.

We have an alternate approach that is even faster pending for 10.10: https://github.com/jellyfin/jellyfin/pull/11511
This will make an hour video's trickplay images to be generated in 5-6 seconds, but the thumbnail will be less precise and some hardware video decoder is not compatible with this(so you have to use CPU in these cases)
