Serviio

Hey all.

I got a DV rip movie, Initially it did not pickup in Serviio but following another post on here I updated the ffmpeg to a newer version (5.0.1) and it now shows the DV rip in the movies list.
Issue that im getting now is that the video has a hectic green tint to it, I read up a little on it but do not fully understand the issue.

Can someone here maybe assist me with asking the right questions, and possibly resolve the issue?
Logs so far did not help much as it looks like it plays the movie fine, just that the color pallet is off.

Thanks in advance.

What are you using as a player? The TV, a Roku Ultra, Nvidia Shield, or some other EV enabled player? What profile has Serviio assigned to that player?

I only have a single DV test file (all of my movie rips are HDR10), but that test clip plays fine through Serviio using my Roku 4800 and my Nvidia Shield through my Yamaha AVR to my LG Nano85 TV. I don't use the player within my LG, so I can't say how it might look there. I've found that almost all TVs have terrible DLNA support.

Seeing the file in the Serviio file list is one thing though do you see the Dolby Vision tag on the TV appear when it's played?

I have an LG CX with the LG profile and for a DV MKV when played, the DV tag does not appear and all green saturation is constantly seen (audio is fine) but when a DV MP4 is played, the DV tag appears and all color is correct. Though after a while playing, audio is lost and does not recover unless restarting the video.

If used with Plex, both file types work fine with DV detected and no audio issue.

That makes it sound like it's being transcoded. I have my doubts FFMPEG can properly convert the DV metadata to SDR, which would account for the color shift. Next time you play the EV file, look at the Serviio console on the Status tab. Find your player in the list and look at the color of the Now Playing indicator. If it's orange, then the file is being transcoded. Green means it's being sent natively.

Yes, I see the DV tag displayed on my TVs, both the LG in the family room and a Vizio I have in the spare bedroom. I didn't even realize the Vizio had DV support until I stumbled across it when playing content from Disney+ on it. However, I'm not using the TV's internal DLNA player. On both TVs I have an Nvidia Shield, which supports DV. I also have a Roku Ultra 4800 on the LG, and it too supports DV.

I just looked at the LG profile, and it has very little functionality. I don't know if the GenericTranscoding section is catching your files, but it transcodes into MPEG2, which absolutely does not support DV. As a test you might try the Roku 4K TV profile, as it will pass 4K material with only a transcode of the audio. It passes the video through intact.

Roku 4K TV results are the same for the DV MP4.

OK. All I can think of is it's something with the player in the TV. I just tried my only DV test file, which also happens to be an MP4 file, using my LG Nano85 player. The DV tag displayed as expected at the start of the video, and colors looked identical to the same file I have in HDR10. This is the clip I'm using:

I downloaded a couple of other test files from the same site, but one is not triggering the DV tag on my TV. Serviio isn't even showing the second one. They are both in the TS format, so I have no idea what might be the issue there. Perhaps the TS container is not compatible with DV, but I don't know why this test file site would have them if that were the case. I did try the one file using the LG player, the Shield and the Roku, and none would display the DV tag, so there's something "off" about the test files.

- DV MP4 video always plays fine and DV supported. It's the audio that stops playing (goes silent) always at the same point i.e. 7 mins in. If I play the DV MP4 using VLC on the Win 10 PC (same PC that runs Serviio), no audio issue and video is fine (but with green tint as expected as my monitor does not support DV).
- DV MKV does not play at all. If I play the DV MKV using VLC on the Win 10 PC (same PC that runs Serviio) audio and video is fine (but with green tint as expected as my monitor does not support DV).
- If I play the DV MK4 or DV MP4 using Plex Server (on Win 10 PC) to LG CX using Plex client, both play fine.

The DV clips I have are too short to be able to see if the audio stops with mine. I checked every UHD movie I've bought, but none have DV, so I just don't have the test material to help any further.
