[FFmpeg-user] Get fatal error informations

Thank you for your feedback.

Are you asking for -loglevel fatal?
No, it was -loglevel error but you've helped me to get it.
But now I understand that ffmpeg is mixing standard output and error output which is a problem for me because I need to calculate progression using the log.

Error output is including the error log with the progress, how can I get them separately.

Example :

Standard output :

Press [q] to stop, [?] for help
frame=   46 fps= 42 q=0.0 size=   15463kB time=00:00:02.26 bitrate=56016.7kbits/s dup=1 drop=0
frame=   57 fps= 35 q=32.0 size=   15477kB time=00:00:02.70 bitrate=46795.5kbits/s dup=1 drop=0
frame=   60 fps= 28 q=34.0 size=   15515kB time=00:00:02.81 bitrate=45134.3kbits/s dup=1 drop=0
frame=   66 fps= 24 q=31.0 size=   15568kB time=00:00:03.07 bitrate=41513.5kbits/s dup=1 drop=0
frame=   73 fps= 22 q=30.0 size=   15596kB time=00:00:03.34 bitrate=38145.1kbits/s dup=1 drop=0

Keep me informed if you need precision.

This certainly has security issues.

While these funny options are probably meant to
increase security...

Are you asking for -loglevel fatal?
