Convert FLV to MP4

-
Use the following command to convert FLV file to MP4.

ffmpeg -i source.flv output.mp4

If you received error (Codec is experimental but experimental codecs are not enabled, try -strict -2) when trying to use the command above, you can try

ffmpeg -i source.flv -strict -2 output.mp4

If you would like to change the bit rate, you can add in ar option.

ffmpeg -i source.flv -ar 22050 output.mp4

What are filesystem capabilities?    For the purpose of performing permission checks, traditional Unix implementations distinguish two categories of processes: privileged processes (whose effective user ID is 0, referred to as superuser or root), and unprivileged processes (whose effective UID is non-zero). Privileged processes bypass all kernel permission checks, while unprivileged processes are subject to full permission checking based on the process's credentials (usually: effective UID, effective GID, and supplementary group list).  Starting with kernel 2.2, Linux divides the privileges traditionally associated...
