VLC 2.0.5 V4L2 HVR-2250 Tuner

[staze]

All,

Having issues getting VLC to work with a Hauppauge HVR-2250. If a open a stream from the device with v4l2c:///dev/video0, it works fine. If I try to open it with just v4l2:///dev/video0, I get a segfault.

Anyone have any idea why this would be? Same thing happens on an HVR-1600, and a PVR-250. Is this because these cards have MPEG2 encoders? I haven't found any good information about the difference between v4l2c and v4l2 handles.

Thanks!

Here's the output from v4l2:///

Then use v4l2c... PVR cards don't quite work in VLC versions earlier than 2.1.

As for the crash, without stacktrace or sample file, nobody can help you.

I'm not actually sure how to attach a core dump to the post...

[Rémi Denis-Courmont]

You can't attach a core dump. It's specific to your build of VLC and way too large. A stack trace is pretty much as far as it goes on the fora.

[staze]

that makes sense. hmm... okay, guess I'll just wait for 2.1 to go final. =/

Thanks!
