Describe the bug This command results in the error below:

ffmpeg -hide_banner \
  -i movie.mkv \
  -c:v av1_amf \
  -quality quality \
  -rc vbr_peak \
  -align 64x16 \
  -preanalysis 1 \
  -t 600s \
  out.mp4

Conversion failed!

However once -preanalysis 1 is removed from the command, everything works.

Setup:

• OS: NixOS 24.11 - kernel 6.10.9
• Driver Version:
  • AMD open source driver 2024.Q3.2 (LLPC)
  • OpenCL 2.1 AMD-APP (3602.0) - FULL_PROFILE
• GPU: RX 7800 XT
• Which component has the issue: AV1 Encoder

Expected behavior I'd expect ffmpeg to continue working.

Please let me know if this is the wrong place for this issue or how I could provide more context
