在研究FreeSWITCH视频会议的混屏问题时候发现一个bug。
已提交jira.
附上代码，问题很明显，不解释
=============================================
version: fs1.6.9
OS: debian 8
file: mod_conference.c
code:
*****************************************************
if (scale_h264_canvas_width < 320 || scale_h264_canvas_width < 180) {
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_WARNING, "Invalid scale-h264-canvas-size, falling back to 320x180\n");
scale_h264_canvas_width = 320;
scale_h264_canvas_width = 180;
}
