Debugging VLC transcoding. HowTo?
Posted: 29 Mar 2010 23:37
Hello
I have a live transcoding VLC. What instrument do I need to use to get information what parameters do I need to tune to get better quality, perfomance, etc.??
Maybe I need to watch my encoded video with vlc player and to look into log files? Or you can advice some better way?
