FFmpeg H264 Encoding causes dmesg error "Failed to load firmware binary. filename=linlon-v52_v76-80-2/h264enc.fwb"

[RogerHardiman]

Hardware H264 encoding on the F3 is failing with a firmware binary error.

ffmpeg command

ffmpeg -y -v 99 -f lavfi -i testsrc -pix_fmt nv12 -g 15 -c:v h264_v4l2m2m  out.264

 

dmesg error

[ 4834.438234] MVX if: Failed to load firmware binary. filename=linlon-v52_v76-80-2/h264enc.fwb.
[ 4834.450002] MVX if: Firmware binary was loaded with error.
[ 4834.450020] MVX session: ffffffd905a1a0f8 send event error. error=-22

 

ffmpeg

Gets some way into initialising. It detects the Linlon H264 encoder, checks images are NV12 format, but then fail with this error

[h264_v4l2m2m @ 0x2abf834870] Failed to set gop size: Invalid argument

 

 

Where do I find this .fwb file, and should it be shipping with Armbian?
