IMAGE OUT problems with UDP Multicast

[stefo]

Hello everybody,

I have a problem with VLC.
When I try to create a image sequence from UDP MULTICAST stream, the error dialog box ( with NTDLL.DLL)is very often displayed.

This dialog box contains following informations.

Error signature:
AppName: vlc.exe AppVer.:0.8.6.0 ModName: ntdll.dll
ModVer.:5.1.2600.2180 Offset: 0002ae24

I use following command syntax

C:\Program Files\VideoLAN\VLC>vlc.exe -V image --stop-time 3 --image-out-format
jpg --image-out-ratio 25 --image-out-prefix "C:\Program Files\Daset2\Stream\Snap
shot\vlcsnap" udp://@239.2.3.230:2314 vlc:quit

I also observed that sometimes the current snapshot image resolution is not corresponded to correct resolution (720x576).
Its resolution is sometimes 528x576, 480x576, 704x576.
This error occurs with all versions 0.8.6a,b,c

Thank you in advance

The resolution should always be the stream's resolution (with some aspect ratio correction taken into account if the source doesn't have square pixels ... if i'm not mistaken).

About your crash, I don't have a clue. Is this only related to UDP multicast?

Btw, this isn't streaming related, so I'll move the topic to another forum category.

hello,

I have mentioned problem only with UDP multicast stream.
Error occurs, not everytime, but very often.
I tried to create a image sequence from capture device and there was no problem with it.
Can you simulate this case.

Thank you in advance
