#1835 closed defect (fixed)

Crash in iOS OpenGL renderer when in background and assertion during destruction — at Version 3

Reported by: ming Owned by: ming
Priority: normal Milestone: release-2.4
Component: pjmedia-videodev Version: trunk
Keywords: Cc:
Backport to 1.x milestone: Backported: no

Description (last modified by ming)

The current iOS OpenGL renderer has two problems:

  • Crash when created in the background.
    When app accepts video call when in bg, without going to foreground, creating OpenGL context will crash.
  • Assertion caused by race condition between rendering and destruction 
    Assertion failed: (vid_tee && vid_tee->info.signature==( 'E'<<24 | 'T'<<16 | 'V'<<8 | 'P' )), function pjmedia_vid_tee_remove_dst_port, file ../src/pjmedia/vid_tee.c, line 277.
