SOLVED: Transcoding not working with A310

Your iGPU is enabled.

Code:

[AVHWDeviceContext @ 0000023c4b0b3f00] Using device 8086:5912 (Intel® HD Graphics 630).

I didn't notice this initially, but the same message is in your original post (I had skipped to the end of the ffmpeg log).

Try different values in the QSV device field. Or properly disable your iGPU in your BIOS.
