Patatra24321 1 Posted December 9, 2023 Share Posted December 9, 2023 Hi, Using Emby in an LXC container on proxmox, hardware transcoding is working fine with QSV but hardware tonemapping give me only a greenscreen. I can use VAAPI hw tonemapping but then the movie is really dark, almost invisible. Here are some screenshots : Intel QSV tone mapping VAAPI tonemapping Not emby, correct result Here is ffmpeg log with QSV tonemapping : ffmpeg-transcode-ee315c75-8a0c-4fdd-81f5-1737d63ddd9a_1.txt And ffmpeg log with VAAPI : ffmpeg-transcode-6fd6bd32-c6e1-4224-81b1-06bfc15d7f43_1.txt Thanks!

Luke 37197 Posted December 9, 2023 Share Posted December 9, 2023 Hi, how did you install Emby Server? Link to comment Share on other sites More sharing options...
Patatra24321 1 Posted December 9, 2023 Author Share Posted December 9, 2023 I've used this script : https://github.com/tteck/Proxmox/raw/main/ct/emby.sh Link to comment Share on other sites More sharing options...
Luke 37197 Posted December 9, 2023 Share Posted December 9, 2023 OK so that just wraps around our debian package, which is good. Are you able to try to the 4.8 beta server and see how that compares? Link to comment Share on other sites More sharing options...
Patatra24321 1 Posted December 10, 2023 Author Share Posted December 10, 2023 Sure, I did. QSV tonemapping is working now ! Thanks But I found that the colors are faded. Here are two pics, one from emby and one not: Emby Not emby I should tell that I have no idea wich one is accurate. I've tried to change tone mapping algorithm but I didn't notice a difference between the three Link to comment Share on other sites More sharing options...
visproduction 124 Posted December 10, 2023 Share Posted December 10, 2023 Emby image with changed brightness and contrast appears closer to reality than the 'not Emby' example which has heavily accented colors. What are the settings for the Emby encoding for brightness and contrast? A scene with a large bright section in the image can get auto exposed darker during the encoding if the brightness and contrast can be set to automatic. It seems like that is a possible setting. I don't know the answer if you can scan and auto expose during encoding. see: https://askubuntu.com/questions/1192801/v4l2-how-to-trigger-automatic-exposure-adjusting Many viewers like to see accented colors where the originals are more muted and realistic. The next photo is a production image from the shoot for color comparison. Link to comment Share on other sites More sharing options...
Patatra24321 1 Posted December 10, 2023 Author Share Posted December 10, 2023 While I was used to the second one, I think that you're right and the emby one is more accurate. We can see more clouds details while the not emby one seem burned 1 Link to comment Share on other sites More sharing options...
