Media tool with support for multiple codecs, filters, and containers. Include your actual command and the complete console output when asking questions involving FFmpeg tools. An easy way to do this is by adding `-report` to your command and pasting the contents of the logfile generated. For help with CLI use only of ff* binaries - ffmpeg, ffprobe, ffplay. For help with API usage, post on Stack Overflow.
