No Picture for some HD Channels

[tbs(apc)]

When watching either live TV or recorded shows some of my HD channels don’t display any video when using the viewer on either my iPhone or iPad. The sound is good. However other HD channels work fine. Also for the channels that don’t work they do with other devices such as Windows 10 DVBLink Viewer and the DLNA function on my TV.

Below are samples from the problem channels.

(I tried the 'upload attachment' but it kept on timing out.)

I have rebooted the iOS devices and retuned the TVSource but nothing has worked so far. Is there anything else I can try to fix this?

(DVBLink Server 6.0.0, iOS 10.3.1, DVBLink Viewer 3.5.3,
Synology DS916+, HDHomeRun Connect 4th Gen)

The video samples you have uploaded are in h265 encoding (Advanced Video Codec)
And it is a very greedy for resources. Your devices should support h265 (or should be indicated - supports 4K ) in order to play such channels flawlessly.

Yes I am surprised that DVBLink Viewer couldn't play these HD channels on my iPhone or iPad.

I have since installed the 8Player app and set 'Use external 8Player' on. So far I have had no problems with these channels.

We are working on in-build player to be more suitable for playing of h265 streams. But can't say for sure when and if it be implemented.
