I am running ffmpeg version 4.2.2 on macOS Sierra and I cannot decode a RAW video.
First I create the .Y4M video:
ffmpeg -y -i inputfolder/GH012088.MP4 temp_raw_video.Y4M
Then I try to input it to ffmpeg:
ffmpeg -i temp_raw_video.Y4M
However I get the following error in the terminal: temp_raw_video.Y4M: Operation not permitted
I have checked the permissions for the 'temp_raw_video.Y4M' file and I have both read and write permissions.
I have tried the above with .MOV videos from an iPhone and it works fine.
The problem seems to be with the .MP4 videos I am trying to convert. These videos were taken with a GoPro camera.
What is going on here? Please see the GH012088.MP4 file info below:

Apparently, the pixel format yuvj420p
is throwing a spanner. I will debug it later.
The header is overflowing the limit assumed by the demuxer. Patched in git master.
For now, use,
ffmpeg -y -i inputfolder/GH012088.MP4 -pix_fmt yuv420p temp_raw_video.Y4M
