Hello,

We are trying to setup ffmpeg on a CentOS7 system without hardware acceleration so that we can convert *.mov files to *.mp4.

ffmpeg V4.3.2 was configured with: “./configure --prefix=/opt/vince --disable-cuda-llvm --disable-cuvid --disable-hwaccels”

The following command, which works on a Mac does not work on the Linux system:

$ ffmpeg -i /scratch/general/video/CE11009_232.mov -c:v h264  CE11009_231.mp4

The output is as follows, but after looking up the error – I still cannot get my head around the solution. Please help.

Thank you.
Vincent Andrews.
