MS Teams' Bot crashing after adding the bot to call

Question

Hi,

I am intermittently getting the following error while extending the recording bot (https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/V1.0Samples/AksSamples/teams-recording-bot).

Exception Caught
A task was canceled.

I am trying to respond after user input using the following code:

await this.audioVideoFramePlayer.EnqueueBuffersAsync(localAudioMediaBuffersList, localVideoMediaBuffers)
.ForgetAndLogExceptionAsync(_logger, "Exception while adding Audio Video Buffers")
.ConfigureAwait(false);

Answer 1

@ChetanSharmamsft There are no fixed steps to reproduce this. But let explain what I am doing here.

There are 2 files - one for Audio and another one for Video. I read those files and convert them to YUV(NV12) Buffers.

In my application, I am continuously sending out Video frames, the Audio frames are sent when some events(irrelevant to this conv) are triggered.
Intermittently while sending these Audio Frames I see the above issue in the application logs.

So far, I haven't been able to spot a pattern, to establish the steps to reproduce.

Answer 2

@Prasad-MSFT By Teams crashing do you mean the SDK crashing ?
I will get back to you with the updates after reducing the data frames being sent.

Answer 3

@Anand Shende have you looked at Recall.ai? It fixed our bot crashing issue.
