Hello,
I would like to stream directly my webcam from linux with ffmpeg.
I launched the following command (seeing the posts and helpcenter):
ffmpeg -f video4linux2 -s "320x240" -i /dev/video0 -f avi "rtmp://1.11645395.fme.ustream.tv/ustreamVideo/myurl/mycode flashver=FME/2.5\20(compatible;\20FMSc\201.0)"
Something seems to happen because the camera is working and I see the verbose output of ffmpeg; but I don't see anything on my channel.
Is there something wrong?
Is it "\20" for spaces and why not "%20"?
I am using mageia 2, ffmpeg 0.10.4
Thanks.
David

OK I finally found the solution : just replace "-f avi" by "-f flv" :)
Now what are the options of bitrate and other quality aspect I can put?
in other words what are the quality limitations for the ustream free account?
Thanks -

lindom13,
What resolutions does your webcam support? I would start with those. You could something in the 500-900 kbps range. -

My actual webcam is supporting 640x480 at at least 25fps and higher resolutions but with less fluid images.
So I want to use it at 640x480
I plan also to use a logitech C615, supporting HD.
Ustream limits the bandwith for free subscription, isn't it?
So for both cameras what would be the best quality available? For example like the best quality that Ustream Producer offers?
Thanks

David,
Limitations would depend on the encoder you use:
I am not aware of any limits when you encode in ffmpeg. I do not have a copy up and running to test with though.
If you are using Producer (free) to encode you are limited to 640X360. If you want to go HD in Producer you will need Producer Pro. -

Generally I can stream OK to USTREAM with the latest ffmpeg (RTMP/Flash/x264/AAC), but
1) sometimes RTMP connection unexpectedly drops, with "No more output streams to write to, finishing." diagnostic in verbose mode... maybe it's a network issue - I still checking...
2) quite often USTREAM's embedded ads "freeze" the encoding process :((( When advertising time has comes - ffmpeg stops encoding and does not send video to USTREAM (I see it from network activity). It has to be cancelled by Ctrl+C then it restarts, connects and work fine .... until next ad. However ads don't stop encoding... but quite often they do...
