In mod_conference 1.6.x, all conference users could get the audio floor
regardless of the kind of video layer they were placed in.
In 1.8.x, the concept of a 'dedicated video layer' was introduced, such that
video layout slots with a reservation ID or a role ID are marked with the
'MFLAG_DED_VID_LAYER' member flag when a member is in the slot, and such
marked layers are prevented from becoming the conference audio/video floor
holder.
This makes sense for the video floor in all circumstances, and the audio floor
in most circumstances.
However, there are some circumstances where allowing users in these dedicated
video layers to become the conference audio floor holder is preferred, such as
when all slots in the layout have reservation IDs, and the audio floor events
are used to manage users in those slots manually.
This adds a conference profile flag, 'ded-vid-layer-audio-floor, which, when
enabled, allows conference members in dedicated video layers to become the
conference audio floor holder.
The 'conference vid-res-id' sub command previously used the CONF_API_SUB_MEMBER_TARGET
command parsing strategy. The standard options exposed by that strategy didn't make
sense for this sub command, so it's now been switched to use the CONF_API_SUB_ARGS_SPLIT
command parsing strategy.
A third, optional 'force' argument has also been added. The default behavior of the
command is to toggle the user in and out of a reservation slot, use the force argument
to ensure the user is placed into the reservation slot provided.
The new signature of the sub command is:
vid-res-id <member_id> <val>|clear [force]
Previously, the font_scale parameter available for the video_mute_banner/video_banner_text
conference channel variable would only accept integer values. It now can accept float
values for more fine grained control, eg:
<action
application="set"
data="video_banner_text={font_scale=.75}Banner Text"
/>
Add params to set min_font_size and max_font_size for video banners.
The hard-coded defaults of 5/24 for min/max font size don't always look good
depending on the layout use case. This adds min_font_size and max_font_size
params for more fine-grained control, eg:
<action
application="set"
data="video_banner_text={min_font_size=8,max_font_size=14}Banner Text"
/>
Regular conference members that are assigned a reservation ID in a layout
are automatically placed in that same reservation ID upon change of a layout.
However, playing files that are assigned a reservation ID are not properly
assigned to the same reservation ID upon layout change.
This patch makes the behavior consistent between the two types.
