Hi everyone! I'm trying to get clarification about v4l/v4l2 support in Wine. As there is no definite answer anywhere in web. I'm using Logitech webcam which is fully supported by v4l2. However, when I'm trying to use it with simple cam capture program in wine, I can see only that device is there, but I can't do anything else with it. I also did a little digging and so have found

https://gist.github.com/oneman/5394332 This is a little hack for sending -live encoded- WebM streams to Icecast from STDIN. An example (I was using libav from git, params likely different between libav, ffmpeg etc programs) avconv -v debug -f video4linux2 -s 320x240 -r 10 -i /dev/video0 -vcodec libvpx -threads 2 -vb 128k -r 10 -f webm pipe:1 | krad_pipe2 europa.kradradio.com 8008 /pipetest123.webm firefox Requires an Icecast 2.4 beta server. Testing on the above server is OK. gcc -Wall -o krad_pipe2 krad_pipe2.c sudo cp krad_pipe2 /usr/local/bin...

...supposedly falls back onto Cortado if your browser doesn't support the <video> tag. The URL is here: http://media.basilgohar.com/stream/ There's been a lot of talk about live streaming and low bitrate streams.

Hello, (This is yet another newbie question.) My goal is to record Video and Audio, from a webcam and microphone, and record them in ogg format. (Using Theora and Vorbis.) I'm aware that I can use video4linux or video4linux2 to get the video. And use various API's for audio. And can use APIs like GStreamer to do the encoding, etc. But, if possible, I like something a little more "higher level". Something that takes care of any audio/video synchronization issues. (But perhaps, in ignorance, I'm ove...

...th=360,height=288 ! theoraenc ! oggmux ! shout2send ip=localhost port=8000 mount=stream.ogg password=hackme (of course, you should change ip, port, etc with your own values). Alternatively, FFmpeg could be used. The following command used to work for me (one line): ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 -s 320x240 -r 25 -aq 2 -ac 2 -ar 44100 -acodec libvorbis -f ogg - | oggfwd localhost 8000 hackme /stream.ogg But it stopped working with recent versions of FFmpeg (I don't know why). I hope this helps you. Feel free to ask further questions. Regards, Andr?s -----------...

Hello, We are working on the Radio station project and we are trying to implement the Live Video Streaming module using Icecast server with VLC player. We have installed and configured the Icecast into our server. Also, we have installed the VLC player in our local desktop computer. The USB webcam(200 CMOS UCAM - DLC220T) has been connected into my machine. Now we are trying to live video

...g cameras... Just some ideas. I was also thinking of coupling --soft-target along with --video-quality to get a minimum video quality, which might be the key to what I am asking. Anyone else have some thoughts on this? For those that are interested, here are my command-line: > time ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -pix_fmt > yuv420p -f yuv4mpegpipe - 2>/dev/null | > ~/packages/theora/examples/encoder_example --video-rate-target 150 > --soft-target - | tee /home/basil.gohar/Videos/webcam-capture-`date > +%Y%m%d`.ogv | oggfwd -d 'Live webcam view of me at work...
