Hi all. I'm writing a benchmark tool for video decoding and transcoding using python and vlc as subprocesses. I found out that trivial line vlc URL -I dummy --sout='#duplicate{dst=display,dst=http{mux=ts,dst=127.0.0.1:8080}}' --loop Is working as expected under linux, but does not under windows: no ...

Hi, We are developing a ip video recording solution based on the vlc player. Right now I'm faced with a task of writing a python script that does: 1) Establish connection to a network stream. 2) Write a series of short temporary files (10 to 30 seconds long) with no gaps from one another without dis...

HI! We've developed a video surveillance application written in delphi which uses libvlc and multiple player instances for video decoding. We also use vlc's vlm for video stream distribution from ip cameras (rstp input ---> http output (sometimes with transcoding from h264 to mjpeg). Everything work...

Hi, I am using vlm to transcode and broadcast a number of ip cams. Those cams cannot show a timestamp on video stream, so I thought of using vlc marq filter. The example is: setup cam101 input "rtsp://192.168.3.101/live/main" setup cam101 output #duplicate{dst=http{mux=ts,dst=:8090/cam101}...

Hi again. The problem has stood up to us once again, so I have to be persistent at this point. Sorry, if I'm being annoying as well. Please, take some time to answer my question: 1) Are there any software-based options to speed up h264 decoding at the cost of video quality, resolution or framerate? ...

So once again... 1) Are there any software-based options to speed up h264 decoding at the cost of video quality, resolution or framerate? I am looking for console-line options and the way to implement them in vlm.conf 2) How can I utilise hardware decoding in practice? When I use vlc player with --f...

I use h264 > scale 0.5 mjpeg chain. So the main cost is decoding h264...

yes. and that's the main performance impact. if just distribute the stream- everything goes on minimal cpu

The point of transcoding is to provide one good stream for fullscreen video and a lighter one for big matrixes and smaller windows (4X4 or less)

Hi, We are using vlc for CCTV solution on both client side and server side. It is great for the most cases, but some ip cams provide only one HD stream for viewing. Although the bitrate is rather low, the number of channels can be up to 36+. The other question is that we don't need the best quality ...

Well, why isn't it a problem under windows? Wget also works just fine...

Hello everyone. I am using vlc 2.0.6 as a ip camera distributor in headless opensuse 12.3. My ip camera brand is Arecont vision and vlc is doing it's job flawlessly with h264 rtsp streams. But when I an trying to catch and distribute an continious mjpeg http stream I get a [0x7fec50001398] main acce...
