Filestream (Ex9.Texture VLC) + webcam freezing / crashing vvvv

#1

Hello,

when using new VLC (but this also happens with “old” VLC plugin) texture to play a webcam stream (and not necessarily using pipet too) vvvv crashes or freezes. Sometimes the stream is reproduced, some other times not: both cases lead, soon or late, to the issue.
I’m not able to reproduce any step leading to this, as it happens (at least for me) randomly.
I’ve run vvvv with /showexceptions, but it simply shuts down or freezes giving no alert.

VLC 2.0.4
beta29 (obviously)
XP 32bit - Sometimes I think I should end my experience with glorious XP.

Dunno if it’s a bug or whatever, so, anyone experienced this, or solved it?

Ah, yes, see attached patch.

Thank you.

Hello,

to be more clear I have to say that:

  • in beta29 I never get images from webcam, and vvvv does not freeze or crash

Instead in beta28.1 I just managed to save a log, which is below.

I saw (in beta28.1) in debugmode that VLC node is consuming less resources than videoin+videotexture combo, giving me the chance to exploit better my old machine. So, can anyone with a webcam tell me if he/she experience the same, either opening Filestream (Ex9.Texture VLC) helppatch with beta29 or the patch above (with beta28.1), please?

Thank you.

I managed to solve this issue installing an old version of VLC, 1.1.9. This has been necessary either in XP 32bit and 7 64bit, since with 2.0.4 or 2.0.5 won’t show any stream (in vvvv, cos VLC stream is working like a charm). Didn’t tried later versions. I’ve got really too much of this.
