Transcoding failing for videos from Samsung S23 Ultra

[ryanwinter]

The bug

Transcoding is failing for many videos in my library (around 4000).

It appears that the video files is missing some Matrix coefficients needed by the x265 encoder.

The OS that Immich Server is running on

Ubuntu

Version of Immich Server

v1.115.0

Version of Immich Mobile App

Hello, can you provide the settings of your video transcoding setup? Also, if you can provide a sample video so we can help reproduce, that would be helpful

Hey Alex,

These are my current settings:
CRF: 30
Preset: superfast
Codec: hvec / aac
Target resolution: 480p
Max bitrate: 0
Tone mapping: Hable
Two-pass: off
HW accel: off

You can see the output settings in the log above, but here it is in an easier to consume format :)

{
  "outputOptions": [
    "-c:v hevc",
    "-c:a copy",
    "-movflags faststart",
    "-fps_mode passthrough",
    "-map 0:0",
    "-strict unofficial",
    "-map 0:1",
    "-tag:v hvc1",
    "-v verbose",
    "-vf scale=480:-2,format=yuv420p",
    "-preset superfast",
    "-crf 30"
  ],
  "twoPass": false
}

Let me see if I can find a sample video that doesnt contain any person information. Maybe I can just try recording some new videos. I'll try and attach something tomorrow.,

Something I noticed, is when I do an ffprobe --show_frames I get the following:

color_range=tv
color_space=reserved
color_primaries=reserved
color_transfer=smpte170m

I assumed reserved is not expected here? If I force the output color space with -colorspace smpte170m or -colorspace unknown at the ffmpeg command line, then it completes as expected.
