Live TV transcoding?

[Trekster 10]

Hi Guys,

 

I'm using the native LIVE TV option on emby, trying to stream a channel in the webclient results in transcoding.

 

See attached. 

 

The same channel does not transcode on Plex which i'm also using as a backup option, the same browser which is the latest chrome.

 

Why does the Emby app transcode? It says container/codec and audi not supported?

It might not be transcoding. It might only be swapping the container. Please attach the emby server and ffmpeg logs:

Thanks.

@@Luke it appears it is transcoding due to unknown codec. I have attached a combined server and transcode log.

Ok well this is interlaced video and browser video players don't have any deinterlacing features. i suppose we could direct play it but then there will be interlacing artifacts.

Can this be made into an option on the server in the future? I don't have this option on plex either but they have chosen to go the direct play route.

 

It works ok in the plex web app - without transcoding - sometimes this is preffered over having to transcode and use CPU ressources, especially if it is an slow box. I don't mind it as i'm running on an Xeon machine, but some others might not.

@@Trekster, since i can't recall the specific problematic situations, i'm going to experiment with allowing this to direct play, and then if other users report problems then we'll see what the best approach is.

 

@@pünktchen or @@Waldonnis, do you have interlaced h264?

 

thanks.

Yes i have interlaced hd channels. Is it in next Beta?

Yes but it will only apply to interlaced h264. Do you have that?

[pünktchen 1409]

Yes.

[Luke 42077]

Ok great, thanks.

I probably still have an interlaced test pattern file here somewhere that I can play with.  What's the issue (and goal), playing interlaced h.264 in Chrome?

[Trekster 10]

It's most likely that there could be tearing. But I hardly notice it.

 

I have lots of recordings to test with of needed.

I believe interlaced h.264 will play in Chrome if it's in a supported container.  Just dragging my sample (mp4 containing a 1080i h.264 stream) into Chrome plays fine (or as well as can be expected).  There may be some dependency on GPU support for deinterlacing, but I don't know Chrome's internals or code well enough to know where to look for that (browser development is "watching paint dry"-esque to me, lol).  Easiest way to tell would be to disable hardware accelerated video decoding in Chrome, but that requires a relaunch and I can't do that at the moment.
