Live TV playback problems in some HD channels

Bruno Bastos

Hello guys,

I've been dealing with this problem for a while but I haven't managed to find a solution.

I've got a lot of image artifacts in some hd channels, these same channels work normally via VLC, recordings are also working normally. The problem only happens in Kodi's Live TV,so I think it's related to tvheadend's kodi addon.

Looking at the logs I've found some logs that seems to be related to the problem:


21:06:33 T:1060    INFO: ffmpeg[424]: [h264] Cannot parallelize slice decoding with deblocking filter type 1, decoding such frames in sequential order

Any help would be welcome.

I got the same problem, but I'm on XBMC 13.2 - so I wonder if the problem is really related to Kodi

It is not happening on all HD channels - only some. I also noticed that recordings are fine - suggesting the problem is related to streaming and/or the XBMC-addon.

I will see if I can pull some logs to see if there are any errors occuring in XBMC. Possible that it also got introduced in the new streaming-features added to TVHeadend lately. I've tried compiling with and without the transcode-options, but that did not change anything.

edit: Ignore my comment in regards to XBMC; my problem is different: I got the same problem in VLC when using the HTSP-plugin. While not impossible that something got borked in HTSP-streaming, I will test further...

My problem is a little bit different, VLC streaming (direct from tvh web interface) and recordings are fine.

Before I've started to use tvh as my backend I was using vdr+vnsiserver and the channels were working normally that's why I think it's tvh addon related.
