Hi,
i'm using such a configuration:
Server: vdr+streamdev_server
Client: vdr+streamdev_client+softdevice(xv output)
Everithing works quite well, but somethimes the client exits and i find some error messages in the logs, i attach the interesting lines. This seems to be an error with the ringbuffer, i can easily trigger the problem with softdevice fullscreen feature. Going fullscreen repeatedly makes vdr exit, but I do not know if the problem is caused either by softdevice itself or by streamdev or even by vdr, so i ask you some help.
Some info on my configuration: i'm using vanilla vdr 1.3.25, streamdev CVS and softdevice CVS, kernel 2.6.11 and i use LD_ASSUME_KERNEL=2.4.1 when launching vdr.
Any hints? Any specific info request?
Thanks for your help, ANgelus.

I guess the attachted log is from the server?
Here is my possible explanation, the softdevice CVS has currently a *very* small buffer, the purpose of this is to make seeking backward in a recording correct. In the near future it will be possible to select the buffersize for correct seeking, save buffers and HDTV buffers, but this is currently not yet implemented. So with this very small buffer the softdevice cannot accept data at anytime, especially when it has to switch from fullscreen to normal mode and back for several times. The result is that also the buffers of the streamdevice run full, and vdr clears the buffers of the server. I don't know why this causes a crash, but I assume that one of the threads of the streamdevice gets canceled which in the end causes a crash.
Please try to use the softdevice version 0.1.2, which is the last stable release and has save buffer sizes. The CVS version is the head of the development, which is _not_ the most stable version.

The log i posted was from the client, nothing strange happened on server side, only a "RIGHT DETACH".

Using a stable softdevice does not changed anything, i suspect this issue is caused by softdevice which maybe show some problem in streamdev or vdr? The exit seems to be from vdr, cTSBuffer::Action() in device.c
Thanks for your interest.

So it is not the small buffers of the softdevice CVS version.
To me it looks like the network connection of the streamdevice gets lost, which in the end causes the crash. I know that on my computer switching from/to fullscreen repeatly takes a lot of CPU power and almost blocks anything else. I never had any crashes when trying this with the softdevice alone, only messages where vdr complained about full buffers. But maybe the loss of the CPU power causes the disconnect?
