Form the logs I see that samples are added to an already full queue. I cannot reproduce this.

20-03-2010 19:06:53.370 [654]Textures will be 960x576

20-03-2010 19:06:53.371 [654]Setting media type on mixer
20-03-2010 19:06:53.377 [654]MyQueue: No more space
20-03-2010 19:06:53.379 [654]MyQueue: No more space
20-03-2010 19:06:53.390 [d50]MyQueue: No more space
20-03-2010 19:06:53.399 [d50]MyQueue: No more space
20-03-2010 19:06:53.412 [d50]MyQueue: No more space

Normally this should never happen. The question is: are the already queued samples important or can they be deleted?

We have the following options now:
1) remove the oldest sample if queue is already full
2) don't add the new sample if the queue is already full (therefore wait until samples are rendered)
3) flush the whole queue in such cases

Having a full copy of the DVD would be helpful for me to debug this as it seems related to the DVD itself. I don't have this DVD in my collection. Would it be possible for you to upload it?

The messages instructing to add new samples are coming from the mixer. It should not send such notifications if the queue is still full. So we need a workaround for this behavior of the DVD Navigator in conjunction with the EVR sample queueing.

Do you have some time to test out some binaries for me? I can create multiple solutions over the weekend and you tell me which behaves/looks correct or at least avoids the crash.

PS: Opened a Mantis for this issue: 0002787: EVR Presenter: samples are added to an already full queue on some DVDs - MediaPortal Bugtracker

hi scythe, i have an original dvd, buy in a Virgin megastore !
is more longer for upload ~4GB, i can test for you and us !

The DVD load with Warnerbros video and crash before the menu animated ! but i have sound !

 

[Scythe42]

OK then I'll create some test binaries for you to test later with this DVD. With your help we should get this one sorted out rather quickly.

azzuro,

here is the first try to fix this. If the Queue Overflow happens the oldest sample gets removed before the new one is added.

Just exchange the dshowhelper.dll (keep a backup of the current one for fallback) and play the DVD.

Let me know if this works for you and if playback looks good. If MP crashes or anything else happens please post the evr.log

To all other: If you don't have the Queue Overflow symptom with specific DVDs, DON'T try this patch.

Edit: First Patch removed

Ok, no sample times this time. Very strange. I keep trying to find out what's happening here in this special case.

azzuro,

here's a second try. This time the queue gets flushed completely. The File you uploaded was somewhat incomplete. At least I could not play it at all.

To all others: If you don't have the Queue Overflow symptom with specific DVDs, DON'T try this patch. If you have the problem, please let me know the exact DVD.
