Just a question. Are you running VLC in a window? If so, is it maximized or minimized. For Windows, minimizing the VLC app stops the memory creep. I'm running VLC on Win2K, 2 instances, one for a TV Tuner and another for a web cam, with both minimized, I can run this computer for weeks at a time wit...

I find this works best for unicast to WMP.

#transcode{vcodec=WMV2,vb=512,scale=1,acodec=mp3,ab=64,channels=2}:duplicate{dst=std{access=mmsh,mux=asfh,url=10.203.1.9:80}}

Use mms: and IP address in WMP like

<Open> <URL> mms://10.203.1.9:80.

I found that minimizing VLC would make the memory usage drop to a reasonable level on Win computers. See if it works for you.

Thanks Antoine, I used the examples in chapter 5 page 38 of the VideoLAN Streaming Howto for "simple broadcasting". All the examples have an output statement. I'll give it a try without the outputs. Back again. Tried the test.vlm file without the output and the video plays on the server bu...

WMP is pretty picky on what it wants and what works with it. Try something like this: sout=#transcode{vcodec=WMV2,vb=512,scale=1,acodec=mp3,ab=64,channels=2}:duplicate{dst=std{access=mmsh,mux=asfh,url=10.203.71.90:80}} Then in WMP use "mms://10.203.71.90:80". The only problem is that this ...

• Is my understanding wrong regarding VLM serving as an rtsp server?
  Is my code wrong?
  Am I trying to do something incorrectly?
  Should I just wait and be patient?

What I've seen regarding playlists and DirectShow is that VLC receives the current state of the PC when it starts. So, if you selected the TV Tuner card with other software and nothing changed that state, VLC may work just fine. On the other hand, it's possible when you re-boot your computer and do ...

OK, I stand corrected, or with a little change, one tuner = one frequency, however that single frequency can include an mpeg transport stream with multiple muxed channels inside of it. So, any digitally muxed single frequency can contain several channels up to the capacity of the carrier. Just didn'...

On a Windows 2000 machine, I just launch 2 versions of VLC, one streams from source 1 (TV Tuner Card) and the other streams from source 2 (USB Web Cam).

Does that answer your question?

It's physically impossible for a TV Tuner, Satellite Tuner or Cable TV tuner to select more than a single channel at a time. So if you want to view, stream or select more than one channel, you need more than one tuner. Even Picture-in-Picture requires 2 tuners to select 2 channels. Good luck on your...

Yes, you need a dedicated receiver for each stream.

Yes, either you can change channels for specific stream through a list-of-channels Playlist or you can switch between streams through a list-of-streams Playlist.

One stream, one channel at a time.

You can change channels through a Playlist.

Multicast will let everyone see the same channel at a time.

Multiple channels simultaneously requires multiple streams.

If you were going to unicast to a Windows Media Player (WMP), I'd use the mmsh:// output with 300kbps or so for video and 64kbps for audio and if you need to work through firewalls, you'd use the mmsh: from a port 80 address. Something like this: #EXTVLCOPT:sout=#transcode{vcodec=WMV2,vb=384,scale=1...

Perhaps if you share your Playlist, others can help.

I've setup a VLM.CONF file called test.vlm that says: new stream1 broadcast enabled setup stream1 input udp://@229.7.7.1:4444 setup stream1 output #standard{mux=ts,access=udp,url=229.10.10.1:4444} control stream1 play The command line says: "C:\Program Files\VideoLAN\VLC\vlc.exe" --ttl 20 ...

One thing I note is that you have the video and audio on the same IP/port number. I think they need their own even port number for each. Also, WMP needs to see an RTSP server response. Chapter 5 in the VideoLAN Streaming howto describes how VLM can respond to RTSP requests and serve up VoD or broadc...

You may have to transcode to something Windows Media Player would like to see or hear. I've found mp3 audio to be acceptable to WMP. sout=#transcode{vcodec=WMV2,vb=512,scale=1,acodec=mp3,ab=64,channels=2}:duplicate{dst=std{access=mmsh,mux=asfh,url=10.203.71.90:80}} This does work with WMP version 9....

If you're just trying to view it on your PC, the playlist does not need an extended "sout" entry, just send it to the "display" device. #EXTM3U #EXTINF:0,11 - TV Tuner Card #EXTVLCOPT:dshow-vdev=ATI Rage Theater Video Capture #EXTVLCOPT:dshow-adev=SoundMAX Digital Audio #EXTVLCOP...

My Kodak USB camera also crashes my computer unless I check the box titled "Device Properties" under "Advanced Options" of the Streaming Device dialog box of VLC 0.8.4.

This check box launches some Windows device dialogs that must be used to prevent crashing.

Success! Was able to run a VLC streaming server from an ATI TV Tuner card to a UDP multicast stream for over 19 hours with very little increase in memory utilization. The trick was to minimize VLC while streaming. It only grew from about 8Meg of memory use to 15Meg of memory use in 19 houres. All ot...

An update on this memory issue. The Windows Task Manager shows the memory allocation for vlc server or client continuing to grow as channels are changed on the dshow device. However, if you minimize vlc, the Task Manager will report a deallocation of memory back down to about 8 meg of memory from so...

Hello, Can anyone verify this information. I've setup a channel listing for a DirectShow TV Tuner card and it works fine except it seems to allocate a lot of memory for each channel switch from the PlayList and even more memory for each channel switch from the http interface. Playlist increases the ...
