We implement an android video chat client use pjsip, but meet a bug? The put_frame function will be call twice, one call is by clock thread and another is by vid_pasv_port_put_frame() function. Than i config the pjmedia_vid_dev_param's native_preview flag, set it to true or false still can?t slove it. I think the additional put frame give us the data what be transport via get_frame , it not be codec than feedback to us by put_frame. I implement the video device in one c file, don't like the ffmpeg video device. And when app is running, there will be two stream object exist. How do i configure it to disable the feedback. -------------- next part -------------- An HTML attachment was scrubbed...
