Hi, What is video-floor-only trying to do in conference? I assume it tries to freeze the floor holder ( and his video) as long as he has video, but in my testing it's not the case, I set the param in the default profile and it seems doesn't make any difference. I tried the following change it looks more clear to me and seems works as what I expected. - if ((!floor_holder || (imember->score_iir > SCORE_IIR_SPEAKING_MAX && (floor_holder->score_iir < SCORE_IIR_SPEAKING_MIN))) && - (!switch_test_flag(conference, CFLAG_VID_FLOOR) || switch_channel_test_flag(channel, CF_VIDEO))) { - floor_holder = imember; + if (switch_channel_test_flag(channel, CF_VIDEO)) { + if (!floor_holder) { + floor_holder = imember; + } else if ((imember->score_iir > SCORE_IIR_SPEAKING_MAX) && (floor_holder->score_iir < SCORE_IIR_SPEAKING_MIN) && + (!switch_test_flag(conference, CFLAG_VID_FLOOR))) { + floor_holder = imember; + } } Another thing I found is that in the normal case(without floor-only set), the video changes according to the volume of the speaker fine, but if the floor press 0 to be muted, there's no chance of other members can get the floor, is there a problem?
