SBS 3D Stuttering
#1
I recently setup a computer and I am accessing my files over from my Synology server. For some reason when I do the SBS 3D files they stutter badly and are unwatchable. I am using Openelec but I felt that this forum was more active and may have more information. This is on a full HTPC that also can boot into windows and can handle full 3D Blu ray ISO's - so I know it is not a hardware limitation. Are there any suggestions or tips as to what I might be able to do to overcome this problem? I am not sure why it is doing this. I have many other 2D movies that seem to play just fine from the same source. Thanks for any help!

debug log (wiki) and the HTPC's hardware specs (GPU model, etc) might give us some clues.

The log was uploaded with id 66736

My system is : and phenom II x6 1055t; 8gb ram, AMD Radeon 6700.

After further testing it is not just 3d movies (which makes sense because the hsbs files are no more than a 1080p 2d movie). It is some of the 2d movies as well and others play great. Cars 2 is a 10gb 1080p file and it plays at 24fps with no stuttering. On others the frame rate drops drastically to around 10fps. As I said I assume it is something with the configuration because this computer can handle plenty when I am in windows.

These files also play fine in Windows and on my WDTv.

Thank you for your help.

More than likely an audio setup error:

"09:49:48 T:139848436619008 INFO: CAESinkALSA::Initialize - Opened device "hdmi:CARD=Generic,DEV=0,AES0=0x06,AES1=0x82,AES2=0x00,AES3=0x0e"

Whatever device your HDMI is plugged into only supports 2 channels:

"09:48:37 T:139848440993600 NOTICE: m_deviceName : hdmi:CARD=Generic,DEV=0

Set to stereo (2.0) not whatever speaker combination it is set to presently.

I tried setting the audio output to 2.0 and had the same results. The same movies play just fine and the same ones stutter and slow to 9fps. I have uploaded a new log ID 67532 of my tests with it output at 2.0.

I use my Radeon 6700 HDMi as audio output. It is connected directly to my Denon 1613 receiver. The receiver definitely supports 5.1 channels but I thought maybe if I set it to 2.0 it would work and send everything pass through. Instead I got 2.0 stereo and same results.

Thanks for any further input. I appreciate the help.

Well for some reason the amplifier's abilities are not being recognised by XBMC, I quoted the relevant lines above.

Maybe the amp is passing through the TVs capabilities?

Try switching off all passthrough options (AC3, DTS, AAC etc etc).

EDIT: oh and make sure the amp is turned on before you turn the XBMC machine on, or there is no info at ALL to detect.
