majstang Posted July 31, 2011 Share Posted July 31, 2011 (edited) Although this is a DVBViewer related issue it started to happened after installing RS 1.9 and continues with RS 1.9.0.3. What happens is sometimes i get a discontinue in the picture when signal for unknown reasons drops from the normal 100% to 24%. There's naturally no logs about it in RS, but when starting the client in debug mode i get this log: 31.07.11 16:06:47.447 EVR SetAspectRatioMode 31.07.11 16:06:49.788 Gotstr SIG 100 31.07.11 16:07:00.604 Gotstr SIG 24 31.07.11 16:07:00.848 EVR Scheduler nextdelta: -4378023 31.07.11 16:07:00.848 EVR Scheduler Dropped Frame 31.07.11 16:07:00.848 EVR Scheduler nextdelta: -4178374 31.07.11 16:07:00.848 EVR Scheduler Dropped Frame 31.07.11 16:07:00.848 EVR Scheduler nextdelta: -3178488 31.07.11 16:07:00.848 EVR Scheduler Dropped Frame 31.07.11 16:07:00.848 EVR Scheduler nextdelta: -2978653 31.07.11 16:07:00.848 EVR Scheduler Dropped Frame 31.07.11 16:07:10.285 Gotstr SIG 100 31.07.11 16:07:20.424 Gotstr SIG 100 Have no idea what this EVR Scheduler does and why it starts to drop frames with the current RS version as streamserver. This has never happened before and the signal from my provider has always been rock stable at 100% for years. Can only blame it on RS. Any ideas? Edited July 31, 2011 by majstang Link to comment
Lars_MQ Posted July 31, 2011 Share Posted July 31, 2011 Have you checked if the RS does detect the hardware correctly? There have been no changes in the hardware handling in the last releases. The evr scheduler is responsible fpr scheduling the frames (=pictures of a video) to be displayed in the DVBViewer. Link to comment

Yes, the hardware detection is correct. This issue is not tuner dependant, i get dropped frames with all my 6 tuners. I'll have to start backtracing and see if it could be provider related, by going back to RS 1.8, where i didn't see this issue (i think ). Link to comment
majstang Posted August 1, 2011 Author Share Posted August 1, 2011 (edited) Hi Again! I actually got some intresting results from my tests. Here's the test setup and the reults: 1. DVBViewer client with EVR Custom renderer and RS 1.8.0.1 for 5 hours - Result 4 dropped frames on two different occasions. Signal drop 100 to 24% and then the EVR Scheduler drops the frames. 1 dropped frame even when there was no signal drop. 2. DVBViewer client with EVR Custom renderer and RS 1.9.0.3 for 5 hours - Result 25 dropped frames on 8 different occasions. Signal drop 100 to 24% and then the EVR Scheduler drops the frames. 3 dropped frame even when there was no signal drop. 3. DVBViewer client with EVR renderer and RS 1.9.0.3 for 5 hours - Result 0 dropped frames. Signal drop 100 to 24% still occurs sometimes. Result is undoubtedly significant. The issue lies within the EVR Custom renderer not abled to handle signal drops. Strange the EVR Custom renderer drops single frames even when there is no signal drop as well, though. Also strange there is such significant difference between when using RS 1.8.0.1 and RS 1.9.0.3, that's why i didn't notice this issue before. Any ideas regarding this result? I'll definitely stop using the EVR Custom renderer until this is fixed. Edited August 1, 2011 by majstang Link to comment
Lars_MQ Posted August 1, 2011 Share Posted August 1, 2011 First of all: If you use the signal strength of the DVBViewer, it gets every 10 secs transmitted, so if you see an actual drop depends on the timing. The EVR renderer drops late/wrong scheduled frames silently, so don't trust the displayed stats. Dropped frames will only be displayed if it can't keep up with rendering them. Your tests only show, that there are times with more drops and times with less drops, nothing more. And you should find the real reason for signal drops and not try to blame it on the software. Thermic problems? Cables? etc. Link to comment

Aha, yes i only looked at the displayed stats when testing with the EVR renderer and didn't confirm there was an actual drop looking at client. Thanks, this information is invaluable And you should find the real reason for signal drops and not try to blame it on the software. Thermic problems? Cables? etc. Yes, you are right...as usual I'll have to take a look at the physical things! Thanks, Lars! Link to comment
majstang Posted August 4, 2011 Author Share Posted August 4, 2011 After lots of testing it seems there is only one channel (Nat Geo Wild) suffering from signal drops in the way described earlier, so no issues with hardware, cables, splitters nor software. I'll have to check this strange behaviour with my provider. Thanks for all valuable information regarding this errand it was highly educational Link to comment
