ffmpeg output video size limits to 4GB

I have a video file of .mp4 format. I want to convert it into .mpeg. But when the output file size reaches 4GB, the conversion stops with a message something like "av_interleaved_write_frame() file too large"

My file system is ext4.

The commands I used are as below :

ffmpeg -i "input_file.mp4" -q:v 0 -q:a 0 -c:v mpeg2video "output_file.mpeg"

ffmpeg -i "input_file.mp4" -q:v 0 -q:a 0 -c:v mpeg2video -fs 8G "output_file.mpeg"

I understand that the conversion target defaults to DVD, so, the 4GB is the upper limit. can I tweak the target ?

Or, is it possible to dump the output to a subsequent file2Out.mpeg once file1Out.mpeg reaches 4GB

For instance, if your input lasts for 2 hours, you can convert the first hour to one file, and the second hour to another file by using -to option to stop at a certain position and -ss (placed before -i) option to start from a certain position:

ffmpeg -i "input_file.mp4" -to 1:00:00 -q:v 0 -q:a 0 -c:v mpeg2video "output_file_h1.mpeg" && \
ffmpeg -ss 1:00:00 -i "input_file.mp4" -q:v 0 -q:a 0 -c:v mpeg2video "output_file_h2.mpeg"

Yes, the reason is the filesystem format. FAT32 doesnt allow an mpeg file to exceed 4GB. thank you
