Scrolling issue.

[plazma 13]

Emby server beta Version 3.0.5667.6

 

Ok ive seen this bug happen a few times but never pinned down a way to replicate, trigger it.

 

What happens is following being in the video player screen and going back to the previous pages chrome loses the ability to scroll up or down using cursor, mouse wheel, pg up/down.

 

To replicate this I tried (to see what happened on the new player interface as I had tried previously) to play a channel on dvbt that's radio only (no video), which I know wont work as the transcode expects video.

 

I do have a few suggestions of how to possible make this work, if tv channels were pre checked at playback to see if they had a video stream, if there was none the channel logo (static image) would be encoded to a 1fps video or just a blank (black only) video with the bear minimum possible video bit rate. From memory (its been a while) ffmpeg could do both. This would allow any client to playback the channel without any modifications to the client side code and use the video player interface. Or if its identified the stream as audio only, just an audio transcode and then launch into the music player interface/strip.

 

Although this may need to a modification at tv plugin level and a change made to serverwmc for example, I don't know im only speculating, is serverwmc relaying the audio channel to emby and the transcoder can ne make it go without video data or is it serverwmc not relaying due to the lack of video stream. As long as its not the latter there is possibility I guess that it could be made to support the audio only channels.

 

Anyway going back to the bug, if I play one of these channels (although I have had it at other times that were nothing to do with live tv (stored media files), radio channels will exhibit the scroll issue every time, after its occurred I can move back forwards click on other things, just scroll is frozen. To fix I close the session (chrome and relaunch) or request browser refresh. Like I say in other places ive probably only seen this occur maybe 2 or 3 times.

 

I sort of understand why it maybe happening, its by no means a major bug or even when it happens a major ball ache to fix/work around if it does, just thought I would mention and also make the suggestion of how audio only live tv support could possibly be added on.
