I playback mkv files from a Plex/Emby server installed on a updated Windows 11 Pro 64bits PC. The CCwGTV is connected to the HDMI eARC port of my OLED TV Panasonic 65HZ1000 and the audio es directed via ARC to my outdated Onkyo receiver.
Plex can play DV titles in any format (M2TS & TS & MP4 & MKV) but Emby refuse to play DV in M2TS & TS files (falling back to HDR10 or other base layer).
By default, the device playbacks DoVi to LLDV unless the Tv doesn't support LLDV, but a few weeks ago the CCwGTV receives its last firmware update which has enabled at last a new option under the Dolby Vision settings that let adjust the type of Dolby Vision HDMI mode, Low Latency or Standard.
I have tried a lot with both modes and I can't distingish any difference in picture quality, so that, or the setting doesn't really work or the Player-LED quality of the CCwGTV is as good as the TV-LED of my TV.
NETWORK:
Embeded 5Ghz Wifi AC. I've metered with iperf3 a maximum local network bandwith of about 120mbps, with good Wifi coverage. Its low local bandwith and its susceptibility to interference made the embeded Wifi not reliable for playback high bandwith files.
I use a USB Type C Hub with ethernet card that gives up to 320mbps of local network bandwith completelly stable with any high bandwith file.
PROFILE 7 DOLBY VISION DUAL-TRACK DUAL-LAYER FEL SUPPORT: NO. It can't play any DoVi DT file, it falls back to the first track (normally HDR10).
PROFILE 7 DOLBY VISION SINGLE-TRACK DUAL-LAYER FEL SUPPORT: YES.
- It plays M2TS & TS & MP4 & MKV totally stable. Tested from begining to end of 150 minutes mkv files.
- Only with some files, if you FF/RW or jump to a concrete scene it loose DoVi processing and stutters. It seems it's related with the version of MakeMKV or software used.
- I couldn't see FEL out of sync neither resuming nor FF/RW a video.
- Compared with internal TV player colors are perfectly accurate.
PROFILE 8 DOLBY VISION SUPPORT: YES
M2TS & TS & MP4 & MKV: Colors are accurate
PROFILE 5 DOLBY VISION SUPPORT: YES
M2TS & TS & MP4 & MKV: Colors are accurate
AUDIO SUPPORT:
Supports:
- Dolby Digital
- Dolby Digital Plus
- Dolby digital Plus + Dolby Atmos
- DTS
- Passthrough of DTS Core 5.1 inside DTS-HD
- AAC
- PCM
- Dolby TrueHD
- Dolby TrueHD + Dolby Atmos
- DTS-HD
- DTS:X
- Kodi, Plex and Emby decode automatically lossless audio into lossless PCM Multichannel up to 7.1, so that if you connect the CCwGTV right to your AVR or via eARC, you could enjoy lossless audio (but not positional Atmos/DTS:X)
As my outdated AVR can't receive multichannel PCM from ARC, my solution is to convert the best quality audio in my language if it isn't supported by the AVR. I do it with ffmpeg converting to EAC3 5.1 1536kbps, and adding it as the default audio track. There are only a few of films with more than 5.1 channels in my language and my ear can't distinguish the EAC3 converted track from the original. But it's my particular case, each one will be different.
KNOWN ISSUES / LIMITATIONS:
- Only with some files, if you FF/RW or jump to a concrete scene it loose DoVi processing and stutters. It seems it's related with the version of MakeMKV or software used.
- No framerate and resolution match (it will be supported in Android 12 if it would be updated).
