How to beat the freeze when viewing iptv for the first time on LG SmartTV?

Question

LG

Question to those who are developing applications for LG Smart TV.
I am developing an application to watch iptv (multicast) on a TV.
The essence of the problem is as follows: if, after turning on the TV, after waiting for the network to initialize, I launch my application and start viewing some iptv channel, then the application at the buffering stage not only hangs, but even the TV itself hangs, and so that even the button EXIT (exiting the application) does not work. You have to turn off the TV.
Moreover, if the TV has been running for a long time, iptv plays without problems.
This almost always manifests itself, and only if the TV is just started, and only when the iptv channel is played for the first time (i.e. if the channel is played for the first time, then the rest are played almost immediately and without any freezes at all)
Maybe someone came across this problem? Or any ideas how to solve it?
I just tried all my ideas!

Answer 1

Taki won the problem!
This is solved as follows. Before launching the iptv channel for the first time, you must first start playing (literally for a couple of seconds) some .mp4 file that can be placed in the folder with the application itself. After this playback, the object that plays the video, apparently, is somehow initialized, and then plays iptv channels without any problems!
Well, of course, this playback of an mp4 file can be disguised as buffering an iptv channel, hiding it behind the download image.

How about Samsung?
