Chromecast IPTV-FFmpeg screen anomaly

I'm having a little display problem while playing my IPTV to the Chromecast. The IPTV source is a M3U file with udpxy links, so the IPTV source is an HTTP video. Maybe it's a ffmpeg parameters issue (maybe I don't really know). Transcoding log attached and picture of the result while playing on the TV (sound works ok).

 

EDIT: I've tried multiple TV's, and the same happens.

I'm not quite sure about that one. It's stream copying the video as-is. You might just have to drop the chromecast bitrate to a low value like 1mbps to force it to fully transcode.

I tryied but I can't change the resolution (screenshot of remote controls attached) in the Android App. Here're some more logs and picture of another TV.

 

P.D.: For me it's not something critical. I don't really use the TV in the chromecast. I just noticed today this anomaly and wanted to report it.

Sorry for the late answer, it works as you said! If I set the "Chromecast bitrate" to something under the stream original bitrate, it fully transcodes it and it is displayed correctly.

 

Thanks! Although it is strange when it direct plays it. But for me it's ok to set a lower bitrate.

I'm having the same problem as you.

 

I think this is an issue for streams with subtitles(ex. DVB-SUB) in them, because when transcoding the video or enabling the subtitle on the stream it works fine.

 

My theory is that the distorted part of the picture is the "non-existing" subtitle.

 

I'm still searching for a solution for this, but I guess this is a "bug"/feature in the Chromecast. A always transcode option would be nice in Emby.

Also getting this error when playing same channel with VLC on iOS/OSX to my Chromecast.

Hi there @@thim, let's look at an example. Please attach the information requested in how to report a media playback issue. thanks !

Logs attached in previous post.

 

The solution to cap the Chromecast stream(to force transcode) is not an option for me since I have multipe channels with different quality, so to get them all to work I have to set it to 2Mbit/s. Which is not a option when having some streams at 20Mbit/s.

 

As I said in my previous post, probably a Chromecast issue - but could be solved with an option in Emby where you could state that ”always transcode” this IP-TV source/shared folder etc.
