Video encoding error: green artifacts.

Videos from a certain phone always get encoded this way these days. original video's screenshot in VLC and Immich's Web UI screenshots attached. I know this didn't use to happen till a few months ago, but today, the user complained that her videos were corrupted so I inspected. Is this a known issue? Couldn't find anything on GitHub.

Could we get your hardware info (phone/server) and transcoding settings?

I've narrowed it down. The problem started somewhere between 5th and 8th December, on my server. It eerily coincides with when I must have updated to this release, which introduced support for HDR videos. I just diffed the ffprobe data of videos before and after this period. The only differences are in timestamps, bitrates and creation date; codecs and parameters are exactly the same. Something changed in how Immich processes the videos.

leaks-repairedOP•4mo ago

Relevant server logs from when that 'currupted' video was processed.

(I might be busy this coming week. In case this is a newly reported issue, I wanted to file on Github.... would love it if someone else could confirm and open it themselves, or I'll do it next week)

IIRC this can happen if a video is Dolby Vision and the client doesn’t support the particular DV profile of the video. Is the video with a green cast the original or the transcode? You can right click and download it to check if you’re not sure

leaks-repairedOP•4mo ago

I just checked. The transcoded video is green in VLC too. The ffprobe-json output for the video is below:

To be clear, these are the commands I used to create the above outputs.

Nothing really sticks out as being problematic in the metadata. Hmm If you’re sure the issue started with the HDR video release, the only transcoding change in that release was #14455

Immich•4mo ago

[Pull Request] fix(server): always set transcoding device, prefer renderD* (immich-app/immich#14455)

sogan•4mo ago

Maybe the change means it’s now using a different interface that leads to this bug It used to always prefer the highest index card* interface

leaks-repairedOP•4mo ago

Could it be that the gpu encoding is the issue? I remember when I initially configured VAAPI, immich would try using it but bail out and use the CPU instead but the logs show that the GPU was used. Any easy way for me to change this and test?

sogan•4mo ago

Yes, there’s a transcoding setting to use a specific device

Mraedis•4mo ago

If you just toggle HWA off it will always go to the CPU 😛

leaks-repairedOP•4mo ago

I experimented; disabling HA solved whatever it was that was happening.

ffprobe-json on the CPU encoded video:

I don't see anything standing out immediately in the diffs, except the encoder name. What's the "level" field?
