Question / Help OBS crashing when streaming & recording using AMF plugin

When streaming and recording at the same time, OBS crashes after a varying amount of time.

This also happened on 16.4 and I updated to see if that would fix but have had no success.

Not sure if this is the AMF plugin or an OBS issue. Can't make sense of the logs myself unfortunately! It looks like it could be some part of the AMD driver thats throwing the spanner in the works, but I'm not sure.

Using:
OBS 0.16.5
AMF plugin 1.4.1.5
AMD driver 'non-whql-win10-64bit-radeon-software-crimson-16.11.3-nov8'

I've attached the relevant logs are linked below with a full system spec from speccy is attached.

Many thanks for any assistance in advance!

I've consulted with the AMD AMF plugin author and he says it's failing inside the driver. Please work through that plugin's troubleshooting guide to see if you can resolve this.

I should have mentioned in my OP - I worked through the plugins troubleshooting steps and looked up the FAQ before posting (as advised on the wiki :o) )
 
Well, here is my analysis of the problem that definitely happened outside of my control:

Code: 
21:31:36.693: [AMF Encoder] Submission queue size is growing. (5/5/180)
21:32:00.615: [AMF Encoder] Submission queue size is growing. (40/5/180)
21:39:01.514: [AMF Encoder] Submission queue size is growing. (175/5/180)
21:39:01.614: [AMF Encoder] Submission queue is full, dropping frame instead...

About 8 minutes before it crashed, the submission queue started filling up. That means that for an unknown reason SubmitInput started taking longer than 16.6ms, and this is also shown in the log. Multiple entries of SubmitInput are randomly spaced apart more than 300ms - 18 times as much as it should have taken.

Next the crashlog:

If you follow the function list in reverse order (bottom to top) you see that it left my control when it says amfrt64.dll - which is when the code called QueryOutput. Then it went to amdave64.dll, d3d11.dll, atiuxp64.dll, atidxx64.dll and finally atiumd6a.dll where it actually crashed. A crash inside QueryOutput is outside of my control and not something I actually expect to happen.

It's best if you make a GitHub Issue out of this and I'll hand off the information to AMD. For that I need the following:

You can create a memory dump of obs64.exe by right clicking on it in the Task Manager Details panel and selecting "Create dump file".
 
Thanks for the great explanation @Xaymar. I had my suspicions that it wasn't something with your control.

I'll reproduce this today and post up an issue on github with the memory dump.
 
@r4b Could you provide the Hardware ID for your card?
You can find it in Radeon Settings under the System -> Hardware tab, it's called Device ID.
