DS418play + Chromecast certain file not playing well

Hi there,

 

I am new to Emby and was jus testing it out to see if it is the right media sever for me.

 

I have Emby installed on my Synology DS418play and use my phone to cast my media to my Chromecast (1080p 2018 model). I have also got myself a Emby Premier subscription so hardware transcoding should work if it's needed.

 

Now I have this video file with the following media info according to Emby:


Video
Title: 1080i H264
Codec: H264
AVC: Yes
Profile: High
Level: 40
Resolution: 1920x1080
Aspect ratio: 16:9
Anamorphic: No
Interlaced: Yes
Framerate: 25
Bitrate: 11,697 kbps
Color primaries: bt709
Color space: bt709
Color transfer: bt709
Bit depth: 8 bit
Pixel format: yuv420p
Ref frames: 1
NAL: 4
 
Audio
Title: Dutch MP2 stereo (Default)
Language: Dutch
Codec: MP2
Layout: stereo
Channels: 2 ch
Bitrate: 256 kbps
Sample rate: 48,000 Hz
Default: Yes
Container: mkv
Path/volume1/Media/Temp/file.mkv
Size: 9916 MB

 

 

When trying to cast that to my Chromecast with the Emby app on my phone the video won't play as it should. Top of the image is ok but the 2nd half is totally wrong and the audio stutters. See the attachement.

 

The CPU on my DS418play is only hovering around 5% while the memory sits at max 50% of it's 2GB (mainly due to other processes that run on the NAS.

 

Is there something that I can do to make this file play smoothly? Should hardware transcoding help with this? Any ideas are welcome.

@@daroy, apologies for the delay. Here is the problem.

 

We are direct streaming the original interlaced video when it should be transcoded instead due to Chromecast not handling it very well. Unfortunately this is a difficult decision because most of the time the Chromecast will play the deinterlaced video just fine, but this is one example where it does not.

 

If you were to lower the in-app quality setting to force a full transcode, then this will resolve it. Additionally, if you can provide me with a copy of the video, i can test it and see if there's any criteria we can use to automatically switch to transcoding instead.

 

Please let us know if this helps. Thanks !
