FFmpeg convert mp3 to pcm error "could not find codec parameters"
20 février 2020, par Hanqing WuWhen I am trying to convert a mp3 file to pcm using the following code, I repeatedly get the error message

FFMPEG cannot encode .MP4 to usable .Y4M RAW video : "Operation not permitted"
26 janvier 2020, par Ham789I 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 :
