Can't find usr/share/ffmpeg either on Linux Mint 14 KDE Edition. :(

@nchu

install 'libavcodec-extra-53'

what now ? =S

sound is way a head of the video, anyone know what command i can add to keep the audio in sync?

@Kranium31 try tweaking the buffer size (-bufsize) up and down and see if that makes any difference.

when i am broadcasting it dosnt show the video it just sits there and says loading

Same problem as @mjrb. Video keeps loading on different devices. Tried streaming on fast @ 1024x640 with 10Mbit/s uplink on 13.10.

This long longer works by the way.

Your live stream will just show a gray box but if you record the video it'll have the video contents.

Example:

To fix the 'Unrecognized option 'preset' Failed to set value 'medium' for option 'preset'' bug, change 'preset' to 'pre' on line 22, and change 'fast' or 'medium' to 'libx264-fast' or 'libx264-medium' respectively.

I had this working before not sure what changed, but on the stream it says live but all I see is a gray screen and "loading video" any help?

I'm a complete linux newbie. This worked great. What about the audio, including mic?

EDIT: Nevermind, the mic works, what about any gameplay audio?
