Error transcoding

[ArneR]

First, Select Intel Quicksync and enable AV1 decoding.
Second, AV1 encoding, according to this thread N150 doesn't support encoding to AV1:

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (native) -> av1 (av1_qsv))
  Stream #0:1 -> #0:1 (aac (native) -> aac (libfdk_aac))
Press [q] to stop, [?] for help

Your processor does not support Encoding in AV1, turn that off.

Then enable
Hardware Encoding Options:
Enable Intel Low-Power H.264 hardware encoder
Enable Intel Low-Power HEVC hardware encoder
Enable VPP tonemapping and Enable tone mapping.

You should be good to go now.
