I'm not sure what goes wrong, tried to install libavcodec-extra-53 along with libavcodec-extra-54 but didn't work out. Runs fine until this red text comes out:

[overlay @ 0x22cfa40] Overlay area (-991,10)<->(310,754) not within the main area (0,0)<->(320,240) or zero-sized

can you paste your options? because there is a problem with your webcam options.

wargio commented 10 years ago

Go on the script and find: [WebCam] overlay=main_w-overlay_w-10:10 [out] then change it to [WebCam] overlay=10:10 [out]

Tell me if it works. if it does, please report immediately, and i'll update the script [edit] i've updated the script. check it. it may work better.

pressure679 commented 10 years ago

Great, I'll check it out, although I can see that some people are waiting to use Ubuntu 14.04 because of some missing release or something, so should I probably. Keep up the good work.

steffansluis commented 10 years ago

I got the streaming working under Ubuntu 14.04 GNOME Remix, mostly by following the instructions from the README. I didn't get the webcam overlay working though, I think it's because of my dual-monitor setup but I'm not sure. I can use MPlayer to feed back the video although I think that might cause it to be out of sync. There don't seem to be any missing packages though.

wargio commented 10 years ago

Well, the overlay should not be affected by the number of the screens. I'll try to build the latest ffmpeg/avconv version and see what happens

manofsticks commented 10 years ago

I receive the same error as pressure679 did with the avconv script (except different numbers), even after trying the overlay change you suggested, and after using your most recent updates.

If I don't use a webcam, it seems to work fine.

Try to change [in] setpts=PTS-STARTPTS, [WebCam] overlay=$WEBCAM_XY [out] to [in] [WebCam] overlay=$WEBCAM_XY [out]

manofsticks commented 10 years ago

I changed it in both instances where that line occurs, since I assume you meant both. No change of result, same thing except different numbers in the error.

try this: Change -vf "movie=$WEBCAM:f=video4linux2, scale=$WEBCAM_WH , setpts=PTS-STARTPTS [WebCam]; [in] setpts=PTS-STARTPTS, [WebCam] overlay=$WEBCAM_XY [out]" to -i $WEBCAM -f video4linux2 -filter_complex "[2:v] scale=$WEBCAM_WH[WebCam]; [0:v][WebCam] overlay=$WEBCAM_XY [outv]"

i'm not so sure about this [2:v] so, if it do not work (black square) or it says it can't find something, then change that to [1:v]
