Program crashing when re-initiating call. #39

Closed Jelop closed 6 years ago

Jelop commented 6 years ago

When a call is initiated from the hololens, hung up and then re-initiated the program crashes. With mixed debugging enabled I get a large amount of output. I've included from the hololens first connecting to the server to the end. But I have omitted many repeated D3D warnings and thread exit messages. One instance of the D3D warning, on the off chance that is relevant is:

D3D11 WARNING: ID3D11DeviceContext::Draw: Input vertex slot 0 has stride 12 which is less than the minimum stride logically expected from the current Input Layout (40 bytes). This is OK, as hardware is perfectly capable of reading overlapping data. However the developer probably did not intend to make use of this behavior.  [ EXECUTION WARNING #355: DEVICE_DRAW_VERTEX_BUFFER_STRIDE_TOO_SMALL]
D3D11 WARNING: ID3D11DeviceContext::Draw: Vertex Buffer at the input vertex slot 0 is not big enough for what the Draw*() call expects to traverse. This is OK, as reading off the end of the Buffer is defined to return 0. However the developer probably did not intend to make use of this behavior.

When you end a call, does the camera stay on? (light on front of hololens + red camera icon top left corner)

jamescadd commented 6 years ago

I need to update my device and will give it another try. One thing I've heard in the past is that other apps that access the camera can cause issues, for example running a Skype call then trying the sample. Hard to tell from the logs above what's going on but it sounds like it is easy to repro. I'll let you know when I try this (likely Monday).

I agree about previous comments. It looks like the camera session from the previous call is not closed down correctly. That is usual reason for second call failing. Some resource that holds reference to video capturer might be left alive when call is ended.

Small update to let you know I'm having some issues with VS after moving from the 2018 Unity tools which we're using with the latest updates back to the 2017 tools. This may take a bit longer to repro as I get a system to do the build in order.

Hey guys, my apologies for the late reply. I have managed to solve the issue. When I first set up my project I had added the block of xml from the PeerCC-Sample readme. But in the process of development I had to delete the unity generated app folder and completely forgot to re-modify Package.appxmanifest. I saw it mentioned in #41 today and so I checked the file, modified it, and since then have been unable to reproduce the problem. Apologies for any time wasted.

Very interesting that it causes this kind of behavior, I would have not expected it. Thanks for reporting back!
