[streaming] Re: Streaming MPEG2 from Hauppauge PVR150 using VLC for Windows?

[Henrik Kjær Nielsen]

Hi,

If I use the GUI (File, Open Capture Device) a new window is opened and I can choose the video and audio device names. For video I can select only the "Hauppauge WinTV PVR PCI II Capture" entry which corresponds to the raw video output (not MPEG2 encoded) on the "Hauppage WinTV PCI II Capture" directshow filter. Similar for audio. There is just no way to choose the MPEG2-encoded output which by the way is to be taken from the MPEG output pin on the "Hauppage WinTV PCI II Encoder" filter (I am referring to the directshow graphs that you  can build and test using GraphEdit).

So if this is not what you do to stream MPEG2 directly, what are you actually doing?

Thanks

Henrik

That's not true for the 350pvr, u cant use it to capture video with in
programs like virtualdub or other generic video capture programs. Atleast
not as far as I know, and have tested. I am referring to the windows
platform and directshow. You do not have to transcode the directshow signal
from the pvr because its already in mpeg-2 format which the vlc server can
just send to the clients.

I do not know a lot about how it works in linux.

Regarding mrl's u can simply use the gui dialog to generate them.

Best regards
Jonas Larsen
