I use the following code to stream UDP packets accross the Internet. I receive it in another vlc but problem is that the quality is quite bad. Can anyone offer a modification? Regards Izack "dshow://:sout=#transcode{vcodec=h264,vb=8,venc=x264,scale=1,fps=32,acodec=mpga,ab=8,channels=1}:duplicat...

Each time one shoud be on focus while the other should be coverd by him until it shuts down completely. In a later time, the one that is in the bacground should start, come into focus and the...

Thanks vlc_help,

I use vlc command line.
I need to capture continually my personal profile video on the PC screen with my webcam, and grab a single image, probably by a hot key or by cursore click, saving it to a file.
Is it possible and how?

Thanks Remi
Ictually I use UDP with the same port for both.
Can I use specific ports for that also?
Is there any document that elaborates on that?
Regards
Kishon

I use LibVlc.dll in my application.
I saw in the documentation that the audio output stream port may be set as different that the video.
Can they share the same output port?
What is the advantage of using specific port for each?

I stream UDP video (including audio) packets with some other tool (WinPcap library) from one PC to another receiver PC. In the receiver PC I run VLC that receives and displays the video-usually fine. Problem is that this tool makes some mistakes from time to time and streams in addition to the video...

Thanks Rémi Denis-Courmont, Can you direct me the details how to use sound from the PC microphone using the same application(forget the other application). I use the command line version to stream the background with "screen://" to a remote site. I want to add audio voice to the stream. Ho...

What I really want is sound from the PC microphone and from some other application.
Is that supported or at list "doable"?
Regards

I use screen:// in order to stream my desktop and I need to support also voice.
Is it possible in current version of VLC?

I'm not sure its the right place to ask for a new feature but I coudn't find a better forum for that... I use LibVlc in my project and need to control the UDP stream output port. Now its random and self determined... Is it possible to add this feature in furure versions (with a corresponding api)? R...

Thanks I really tried it myself but couldn't make it. Here is the comand that I use to display the screen view locally, while udp trascoding to a remote PC on ip:port = 100.0.0.11:8081. The vlc seems to choose this way the output port randomally- vlc screen:// :sout=#transcode{vcodec=mp4v,vb=2048,sc...

I use a command line with libvlc to stream to another PC. What is happening in the socket level when in the middle of UDP streaming to the unicast client I do a "pausing"? Does the VLC releases the socket and than alocates again when resuming the stream? Any elaboration would be great. Reg...

I need to stream using unicast UDP. Controling the detination is documented and works fine but I can't find how can control the streamer output port.
Can someone help please?

I use LibVlc dll and indirectly all the plugins in my C# application similar to the following(the actual command is different but the idea is the same) - vlc screen:// :screen-fps=30 :screen-caching=100 --sout '#transcode{vcodec=mp4v,vb=4096,acodec=mpga,ab=256,scale=1,width=1280,height=800}:rtp{dst=...

I want to stream UDP to a remote PC that is behind a nat router. My PC is also behind a nat router. Is there a recommended way how to implement the nat traversal communication(I think that it uses tcp also and also more than one udp port).

Thanks,
I'm not completely sure but it seems to help in the sense that statistically it happens less than before.
If you can farther advise to eliminate the problem completely I'll be very grateful.

I use VS 2005 and develop in C# (and C++ for the LibVlc.dll) and use interoperability. Problems is that sometimes, running under debugger it is stack in the middle of the launch. Watching the output window I can see the following log when it woks fine(it has some more lines which I neglected here fo...

Hi all, I have 2 questions regarding controling the input and the output frame rates. 1. I stream with VLC command line interface. I use "dshow://" to capture webcam and want to reduce the frame rate. WIth the GUI interface I manage to reduce it to 6 farmes/sec, how do I modify my input, &...

I use UDP streaming (with a version that is earlyer then the newest) from my web camera using a dos box. It works fine but since the line is quite bad I need to use low baud rate - around 100 kb/s. This causes quite a poor picture, though the frame rate is much above my needs. My thouts are to reduc...

I use the Windows standard GUI.
With UDP streaming I see that I can stream to a single ip-port address.
Is it possible to stream to 2 or more PC's by using comma or semicolon in the address field?
Is it possible to do it in command line user interface?

Hi all, I use LibVlc.lib in my C# program. The program recieves a stream from the LAN and transcodes to another PC on the LAN and it works fine. I can modify the input stream paramters (like using another PC source) but that causes the other PC (that constantly recives the transcoded stream from my ...

I use the following advanced string settings in order to stream to a remote PC. :sout=#transcode{vcodec=mp4v,vb=16,scale=1}:duplicate{dst=display,dst=std{access=http,mux=asf,dst=10.0.0.11:8081}} Though I set vb to 16, I see in the remote PC statistics info that it consumes 1400 kb/s if it located on...

Dear Sir,
Unfortunately I'm a beginner with WPF and also with VLC and I really don't know what's the meaning of "Mark bindings"?
Can you please direct me by a link or some explanation?
