Crash on accepting incoming video call

[devanshvyas]

App is getting crash on receiving incoming video call:

I'm using this code for accepting the video call:

var msgData = pjsua_msg_data()
pjsua_msg_data_init(&msgData)

var callInfo = pjsua_call_info()
pjsua_call_get_info(id, &callInfo)

call_opt.aud_cnt = 1
call_opt.vid_cnt = self.isVideoPossible(callId: id)
print("video count", call_opt.vid_cnt)
pjsua_call_answer2(id, &call_opt, UInt32(code), nil, &msgData)

I'm getting following Logs:

Hi @devanshvyas, would you mind filling out our issue template?

That makes it way easier for us to track down any possible bug.

Thanks.

Btw, I also doubt that your issue is related to this repository, is it? But rather to pjsip.

[devanshvyas]

@welljsjs Not sure, As I have created Carthage using this getting crash on incoming video calls. It gets crash on calling pjsua_call_answer2

[welljsjs]

@devanshvyas What version are you using? Upgrade to 2.9.0.2 if possible. It's not related to this repository if it has to do with the pjsip internals, which seems to be the case. It is related to this repository if you're having compiler or linker errors. We do not maintain pjsip. This repository is available via cocoa pods. It aims to make pjsip available for Apple platforms, such as iOS and macOS. If you still think that your issue is related to this repository, please fill out our issue template. That way, you provide us with some useful information so we're able to help (otherwise, this issue will be closed in 30 days). That said, I don't know why you're using pjsua_call_answer2, if there's no specific reason for that, I'd go with pjsua_call_answer instead. Also have a look at the docs.
