MAG250 - Occasionally problem with playing TV stream - black screen

[MartinF]

In normal viewing station suddenly disappears video and sound. TV screen stays black and on the bottom of the screen is the information about actual TV program from EPG data.

After about 10 seconds, the video and audio starts and everything is fine.

If the customer within 10 seconds trying to switch to another station, so it runs the new station up to 1 second (video and audio) and then screen stays black. (This applies to any other station.)

If customer left BOX 10-20 seconds at rest then everything return to normal.

We don't have a problem with the stream, because in the stream logs we don't see any problems.

Has anyone reported something similar?

We have: ImageVersion: 0.2.16-r2-250,  Stalker Version 4.8.76

Please show debug log from the STB when this problem occurs. http://wiki.iptv.infomir.com.ua/doku.php/en:stalker:faq#how_to_run_the_stalker_portal_in_debug_mode

But most likely the problem with stream or network (packet loss).

I would like to show debug, but this problem occurs only 1-2 times per week. How do I set the STB to send debug output somewhere on an external server?

Unfortunately, it only works on the STB. 

Also you can enable stream error logging, just add to the server/custom.ini lines

enable_stream_error_logging = true
enable_stream_losses_logging = true

The error messages will be in stream_error table (in DB);

Thank you for your ideas. Now I saving logs of multicast, IGMP protocol packets and debug the portal, but the problem has not yet occurred. When a problem occurs and I'll have logs, then publish them here.

This parameter I already had switched to true in "custom.ini":

enable_stream_error_logging = true

This I did not have in "custom.ini", so I added this parameter.
enable_stream_losses_logging = true
