IOS Version crash randomly #63

Open songzhe1988 opened 8 years ago

songzhe1988 commented 8 years ago

Hi there, I ran across a issue that the IOS app that I built (actually I just made another view controller in the native demo) randomly crashes during the video chat, throwing a EXC_BAD_ACCESS exception:(gstglcontext(14):EXC_BAD_ACCESS (code=1,address=0x30)) on gst_glimage_sink_on_draw. I have no idea what is going on here, did I made a mistake somewhere or it's a bug from the sdk? Thanks.

I get the same error. Unprovoked after just leaving it for a few minutes without touching, it crashes at gst_glimage_sink_on_draw. Stack trace:

Hey just I had the same issue. Did you solve it?

xelven commented 8 years ago

seems draw_cb problem still had now?

I guess are same issue with https://github.com/EricssonResearch/openwebrtc-ios-sdk/issues/27 take look at my solution first.

cwack-letsdev commented 8 years ago

OK thanks. I'll try it out. The issue doesn't happen so often. Do you have a way to get it reproduced to verify if it's fixed?

xelven commented 8 years ago

In my version, it is in any video chat then press home button let that app goes background, then the issue will 100% happened. since when the app going background and draw_cb still callback from glwindow to redraw the video frame but the handler is unavailable anymore.

xelven commented 8 years ago

BTW. here is my version used.

cerbero version 2015/12/4
openssl: Bump to 1.0.2e

Has the sdk been updated to cater this issue? I am facing the exact same issue. The app crashes randomly with the above error. I have been trying for days to find a fix but nothing has worked for me till now :( Please can someone tell me how to get rid of these crashes?
