Sorry for the duplicate posts yesterday, short story: I made a mistake. My question relates to v2.8 Anyway, on my journey to understand and work with Pjsip video, I made an interesting discovery. I am looking for a sample nop/null video sink, and I came across these lines of code in ...\pjmedia-videodev\videodev.c /* extern functions to create factories */ > #if PJMEDIA_VIDEO_DEV_HAS_NULL_VIDEO > pjmedia_vid_dev_factory* pjmedia_null_video_factory(pj_pool_factory *pf); > #endif Interestingly, while the function is declared, it is not defined,nor used anywhere. [I searched the full git repo. and release 2.4.5] I am wondering, does anyone know where I can find the body of this method? Also, does anyone know if this implements a null sink, or null source? [if source, then I know colorbar is not too far off, but if it is a sink, it seems a much easier place to start then one of: sdl_dev.c, dshow_dev.c, or android_opengl.c Thank you, Cameron

Hi Cameron, Thanks for noticing it. It was never implemented indeed. I removed it in r5902 (https://trac.pjsip.org/repos/changeset/5902).
