Looking for validation of config file

Hi, I’m currently looking to verify if following things can be achieved using SMA

Question 1: After qBitt has downloaded the video, it will call SMA on the file (Changed settings in qBitt as described in wiki) SMA has to convert the video(any codec format) to H264 8bit codec (Ignore if it’s already in this format) and replace the old file SMA will finish transcoding and hand back control to qBitt, which will hand back the new transcoded file to *arr

Is this what’s happening under the hood?

Question 2: I want SMA to transcode the video using my custom ffmpeg with h264_v4l2m2m encoder/decoder only (H/W accl is possible using h264_v4l2m2m on raspberry pi 4 for 64bit OS’es) Example on how SMA should call ffmpeg: ffmpeg -c:v h264_v4l2m2m -b:v 8M -c:a copy -i input.* output.mp4

Does the config file below suit the above behaviour?

Thanks man! I shall setup SMA in my Pi right away!

Got it, this can technically be solved by setting the pix-fmt option in autoProcess but I went ahead and just hard-coded it for the h264_v4l2m2m class
