[Freeswitch-users] conference member play image file

Using Freeswitch 1.8.5 release version we are trying to play a PNG image file to individual video conference members.

Per confluence the API is:

conference <confname> play [{vol=<volume>,full-screen=true,png_ms=100}]<file-path> [async|<member_id> [nomux]]

Doing this API and omitting the details after the file-path, the PNG image is displayed to all conference members.

If we include the member_id afterward in order to send the image to just one member, suddenly Freeswitch complains:

2019-05-10 10:23:11.288415 [ERR] mod_png.c:120 Channel has no video and audio_file is not set!

To confirm, the participant is a video channel.
