Resolution is adjusted incorrectly

[Gerrit507 24]

Hello, 

 

I reported this issue already here:

https://emby.media/community/index.php?/topic/47197-transcode-to-lower-resolution/

 

But it was obviously the wrong topic

 

Description:

I have a PC that accesses my emby server remotely. My emby server has an upload bandwidth of 20 Mbps. The PC is connected to a UHD screen. Emby detects that and limits the resolution to UHD accordingly. The problem is that UHD@15 Mbps looks much worse than HD@15 Mbps. The option in the player says explicitly "1080p 15Mbps" but emby is still encoding in UHD because of the screen. When I set it to 720p 4Mbps, it encodes in 1080p... I made a crosscheck with emby for kodi, set resolution in kodi to 1080p and enabled the option to limit the video resolution to the screen resolution in the emby for kodi addon and the quality looks way better.

 

Long story short: When the user chooses HD 15Mbps, the source file resolution is higher than HD and the screen has a higher resolution, emby is still transcoding to that higher resolution, which causes a worse quality then using HD with 15Mbps. In my opinion emby should adjust the resolution to the chosen bitrate/bandwidth. This also affects the option of the bandwidth limit for remote connections. Emby is not adjusting the resolution to that limit.

I have to correct myself. It is not depending on the monitors resolution, only on the resolution of the video, which also on a 1080p monitor the transcoding keeps the resolution of the video no matter what setting I take, only if I choose a really low bitrate.

I'm looking into this for the next release, thanks.
