VLM differences GUI-wx vs telnet+http in parsing and dshow
Posted: 24 Mar 2006 12:34
Hello,
I work with win32 nightlies - vlc-0.8.5-test1-20060322-0132, WinXP SP2, IE 6.
I found several bugs:
1. I would like setup mosaic from webcams by http intf. There is a problem, that http intf crashes vlc on loading png fake file, while command line setup fake-file works.
2. VLC http mosaic intf is not usable with IE6 - add INPUT and set position in mosaic don´t work (IE
)
3. There is a difference in parsing VLM scripts (I guess). I mentioned here, that VLM from GUI-wx (win32) is not able to load or run vlm batch scripts from a file (...C:\ in path...).
I run mosaic from command line by
I tried to add --extraintf http:rc:wx and the message before crash was error in vlm file. So there is a difference in usage vlm.conf files between wx GUI and telnet+http.
My mosaic VLM conf is
4. There is a difference in usage of dshow devices between VLC (command line, GUI) and VLM (telnet, http).
In VLC GUI "Video device name" menu I can see
Default
None
MSI Star Cam 370i No1
MSI Star Cam 370i No2
MSI Star Cam 370i No3
as I renamed FriendlyName thanks to garthb76 patch. I can watch video from webcam 1, 2 or 3. I can also use command line to open dshow device of required webcam
If I try to PLAY element kamera1 from http or telnet VLM interface, it is not able to use specific webcam. It is only able to open (default?) dshow:// It doesn´t consider what is written after dshow:// and in setup kamera2 option dshow-vdev="qwert" too.
The message is "dshow://:dshow-vdev="MSI Star Cam 370i No1" succesfully opened", but it is not truth.
Here are the messages about trying to PLAY webcam No2
I can click PLAY whatever webcan I want, but only the default one is opened and no other. So VLM commands are not able to use specific dshow device
If somebody with Direct Show knowledge has time or desire to fix this problems...
Thank you
Albert
