For example, specify “-b:v 299k -bufsize 299k” on the command line to start encoding at 299kbit/sec, then to adjust the encoder bitrate to 200kbit/sec during encoding, type:

Its not that you shouldnt use gotos but rather that you should write
readable code and code with gotos often but not always is less readable
