Hello,
I use this command to compress videos made by my family members with their
mobile phones, DSLR cameras, etc.
ffmpeg -i [INPUT-FILE] -y -f mp4 -c:a libfdk_aac -b:a 192k -c:v libx264
-crf 23 -preset slow -map_metadata 0 [OUTPUT-FILE]
I have noticed that I get a bunch of warnings when compressing videos made
by a GoPro camera.
FFprobe:
"Unsupported codec with id 0 for input stream 2"
FFmpeg:
"No pixel format specified, yuvj420p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players. "
FFmpeg does do the job though and I am able to open the output file with
VLC player.
I was wondering if there is something I should be aware about. Just don't
want to run into issues with the produced files in future.
Any tip/advice would be greatly appreciated.
full outputs of FFprobe and FFmpeg posted below.

Thanks,
Andrey
