[Freeswitch-users] video problem in conference with H264

[Seven Du]

Answer myself.


I traced code and found that in line 1007 of mod_conference the frame data never matches 0x11

} else if (vid_frame->codec->implementation->ianacode == 99) { /* h.264 */
iframe = (*((int16_t *) vid_frame->data) >> 5 == 0x11);

I hardcoded to iframe = 1 and then it works.

As I said I don't have problem with Bria, but with the xtp8886 device I got the following data sequence. I'm not familiar with video encoding, so is my device broken or we need other methods to detect an i-frame or is it safe to just hard coded into 1?

Thanks.



*(int16_t *) vid_frame->data,  *((int16_t *) vid_frame->data) >> 5
