dshow capture problems in 0.7.0-test1

[Paul Forgey]

I'm trying to stream from a directshow source. This works OK with the default settings, however it's always at 320x240. If I specify '320x240' as a size, it appears to get the chroma wrong (I left it unspecified). If I leave the size unspecified, I get 320x240 with things working fine. If I specify 640x480, VLC crashes.

Is setting the size known to not work? Is there any way I can get full 640x480?

Hey,

just thought I'd say that if I specifiy the 640x480 as the size, the chroma is wrong, but VLC doesn't crash.

So uh, yeah, nothing worthwhile really, just saying a stupid "mE toO!"

This is a known problem.

Well, I for one didn't know about this

Could you have a look at the debug messages.
There should be the full list of supported modes (sizes, chroma) somewhere. Only the sizes shown in there will work.

But it still means that there is a check that isn't done correctly in the code and that vlc is using the size you provided while the directshow input uses one of the supported size... I'll have a look at this.

And indeed 640x480 (aka VGA) is not a supported size. But the chroma is still screwed up when specifying a (well, the) supported size. That's too bad the DirectShow filter is limited to this, because the hardware is very capable of going 640x480. Maybe time to switch to v4l.

Someone was in and reported this a couple of days ago. i thought you were there? anyway. i'm so swamped at the moment, i mix up everything.

I'm actually not certain the results of the enumeration are correct.. The PVR application which comes with the card uses the same DirectShow drivers to both overlay and compress into an MPEG stream full 640x480.

Yep, it was me and another on the IRC
