pause_play command not working when playing video file

[mxk1011]

Describe the bug When using FS in a video conference, you can use command play to play a video file in the mux. This works as expected. But it is not possible to pause the recording.

To Reproduce Steps to reproduce the behavior:

1. conference name play {full-screen=true}https://my-file-hoster.com/file.mp4
2. conference name pause {full-screen=true}https://my-file-hoster.com/file.mp4 This will output 2020-10-04 00:25:53.202944 [INFO] conference_api.c:3841 Pause recording file

... but the file keeps playing with audio and video. When doing the command pause_play, you will get following error:

-ERR Member: 0 not found.
pause [<member_id>]

Expected behavior The played video file should stop playing

As FS is downloading the HTTP file to temp storage, I tried this file path as well, but with the same result, that the video keeps playing:

freeswitch@75718438e67e> conference 3dd163b0-0199-11eb-86a7-39b0df2e6d68 pause /var/lib/freeswitch/storage/http_file_cache/2c6aa267a46402d1066f236109541a63.mp4

freeswitch@75718438e67e> conference 3dd163b0-0199-11eb-86a7-39b0df2e6d68 pause_play
+OK Pause

By doing this, the AUDIO of the currently playing file will stop, the video will continue

[anthmFS]

pause_play pause is for recordings

[mxk1011]

@anthmFS not as per documentation here https://freeswitch.org/confluence/display/FREESWITCH/mod_conference Pause playback of file to a conference

Is there then another command to pause a playing file? As I see there is only a command to completely stop the playback (stop)

EDIT You are right, pause is unnecessary to use here as not for playback at all
