Issue:  Transcoding a video that should direct-play.

Observations:  Same video direct plays correctly when casting from Pixel Phone to Vizio TV (smartcast), but not when casting to Google Chromecast Ultra.

Log indicates resolution issue:  

Reason=Unnamed.Width Condition: LessThanEqual. ConditionValue: 1920. IsRequired: False.

I have reviewed the media info for the video file, and it looks like it fits Chromecast Direct (almost).

  • MKV/HEVC 265/AC3

(MKV should cause direct streaming since CCU wants MP4, but not transcoding)

Any videos that are MKV/264/AC3 direct stream

 

Related Details:

  • Emby Server 4.6.7.0, also tried 4.7.6.0.  (Same result)
    • Running on Rocky Linux 8.6, 8 vCPU, 4GB RAM
  • Vizio 4K Smart TV with Smartcast (Netflix does 4K fine)
    • very good connectivity
  • Chromecast Ultra (Netflix does 4K fine)
    • very good connectivity
  • Google Pixel 5 and Samsung A7 Lite tablet
    • Android: Emby for Android App 3.2.77
    • Android device casts to TV or CC Ultra, then directs playing the content
    • App settings on both devices specify local lan and chromecast playback 4K 160mbps

Any change there is an issue with the Emby for Adroid App not passing the right device info for the chromecast?  Or another Google Chromecast change causing Emby to think the max resolution is 1920?

What am I messing up?

hi @sfcredfox can you please try this again and let me know if you're still running into this? I tested on my chromecast ultra and was able to play 4k just fine. Thanks !

Did you test with version 4.7.8.0?

I upgrade again and test.

I tested again today on 4.6.70, same result.  It thinks the resolution is not supported.  Just not sure what's not configured right.

Did the second log show anything more useful than the first?  My wife's android device was used on the second attempt in case there was something wrong with mine app.

 

Thanks.

@Luke

Upgraded to 4.7.8.  Issue still exists for me.

Is the DLNA server service trying to contact the internet for something?  The media server and the chromecast ultra are on the same IP subnet for obvious reasons (since that's how DLNA/broadcast/chromecast/multicast/etc works).

I think I can assume this is Emby trying to auto udpdate? 

Command line: /opt/emby-server/system/EmbyServer.dll -programdata /opt/emby-data/ -ffdetect /opt/emby-server/bin/ffdetect -ffmpeg /opt/emby-server/bin/ffmpeg -ffprobe /opt/emby-server/bin/ffprobe -restartexitcode 3 -updatepackage emby-server-rpm_{version}_x86_64.rpm

@Luke

Would you be willing to look at how the application handles: 

App: GetPostedPlaybackInfo request:

I can't really tell if this is something queried from the device, or just showing the profile you have coded into the app.

The response I get when casting to a Chromecast Ultra and a Vizio Smartcast TV are almost identical.  The chromecast ultra supports more formats in for video/audio, but the app still forces transcoding when playing HEVC to a CC Ultra:

 

 

 

 

 

Here's where it decides to transcode, look at the end of the line: 

Info Server: http/1.1 GET http://172.20.16.201:8096/emby/videos/21821/stream.mkv?DeviceId=chromecast_1666214891320&MediaSourceId=e4f53893c2a1a336d1ef10d41d60a590&StartTimeTicks=26296440000&PlaySessionId=5e9306293d3a497ab0d2094ffb539a99&VideoCodec=h264,h265,hevc,vp8,vp9&AudioCodec=ac3,eac3,aac,mp3,opus,flac,vorbis&VideoBitrate=159360000&AudioBitrate=640000&MaxWidth=1920&AudioStreamIndex=1&TranscodingMaxAudioChannels=6&CopyTimestamps=true&h264-profile=high,main,baseline,constrainedbaseline&h264-level=62&aac-audiochannels=2&TranscodeReasons=VideoResolutionNotSupported.
Quote
TranscodeReasons=VideoResolutionNotSupported

 

Looks like this part of the codec profile: 

"CodecProfiles": [
  {
    "Type": "VideoAudio",
    "Conditions": [
      {
        "Condition": "Equals",
        "Property": "IsSecondaryAudio",
        "Value": "false",
        "IsRequired": false
      },
      {
        "Condition": "LessThanEqual",
        "Property": "AudioChannels",
        "Value": "2",
        "IsRequired": true
      }
    ],
    "ApplyConditions": [

    ],
    "Codec": "aac"
  },
  {
    "Type": "VideoAudio",
    "Conditions": [
      {
        "Condition": "Equals",
        "Property": "IsSecondaryAudio",
        "Value": "false",
        "IsRequired": false
      }
    ],
    "ApplyConditions": [

    ]
  },
  {
    "Type": "Video",
    "Conditions": [
      {
        "Condition": "LessThanEqual",
        "Property": "Width",
        "Value": "1920",
        "IsRequired": false
      },
      {
        "Condition": "EqualsAny",
        "Property": "VideoProfile",
        "Value": "high|main|baseline|constrained baseline",
        "IsRequired": false
      },
      {
        "Condition": "LessThanEqual",
        "Property": "VideoLevel",
        "Value": "62",
        "IsRequired": false
      }
    ],
    "ApplyConditions": [

    ],
    "Codec": "h264"
  },
  {
    "Type": "Video",
    "Conditions": [
      {
        "Condition": "LessThanEqual",
        "Property": "Width",
        "Value": "1920",
        "IsRequired": false
      }
    ],
    "ApplyConditions": [

    ],
    "Codec": "hevc"
  },
  {
    "Type": "Video",
    "Conditions": [
      {
        "Condition": "LessThanEqual",
        "Property": "Width",
        "Value": "1920",
        "IsRequired": false
      }
    ],
    "ApplyConditions": [

    ]
  }
],

 

Looks like even though it's a supported direct play file, it still doesn't like something about the "LessThanEqual" width 1920 and forces h264?

Here's the media info:

It's plugged into a 4K TV, same Vizio TV that can direct play.

CEC is enabled, and the Ultra doesn't seem to do anything weird with 4K from streaming apps.

I would just drop the CC Ultra since the Smartcast is fine, but I use them for the other TVs, and no other smart TVs, so really hoping I can figure out why my setup is acting different.

For Vizio Users:

Figured this out, I'm pretty irritated about it. Turned out to be the TV's fault. 

Vizio put in a 'feature' in the firmware where each HDMI line can have the UHD (4K) turned off.  This wasn't an option when it was working correctly, so that's why it stopped working.

The query response now makes sense why it was saying it could only support 1080 in the conditions/parameters.
