3 years ago Some HW transcoding will not write HDR metadata so be aware of that (NVidia for example does not). As far as the metadata is concerned, you need to either specify the metadata in the codec-parameters under the HDR and Video sections or turn on dynamic-parameters (which applies to both)
codec-parameters =
dynamic-parameters = FalseThis thread goes over a lot of the development and options related to HDR metadata

Hi,
First let me congratulate you for your script, I've been using it for at least 1 year and it works flawlessly !!!!!
I have a Windows 10 machine, Python 3.8 64 bit, the latest version of your script, the latest build for FFMPEG and my standard use case works without any issue : converting all my files to MP4 using HEVCQSV (and all the audio and sub that I like...).
Now that Plex supports tone mapping I wanted to use the new HDR feature of your script to keep HDR metadata during transcoding.
Here is my Autoprocess.ini (I just copied the HDR configuration from the readme) : [Converter] ffmpeg = C:\Script\ffmpeg\ffmpegHDR.exe ffprobe = C:\Script\ffmpeg\ffprobeHDR.exe threads = 0 hwaccels = dxva2, cuvid, qsv, d3d11va, vaapi hwaccel-decoders = h264_cuvid, mjpeg_cuvid, mpeg1_cuvid, mpeg2_cuvid, mpeg4_cuvid, vc1_cuvid, hevc_qsv, h264_qsv, hevc_vaapi, h264_vaapi hwdevices = vaapi:/dev/dri/renderD128 hwaccel-output-format = vaapi:vaapi output-directory = output-format = mp4 output-extension = mp4 temp-extension = minimum-size = 0 ignored-extensions = copy-to = move-to = delete-original = False sort-streams = False process-same-extensions = False force-convert = False post-process = False wait-post-process = False detailed-progress = False preopts = -ss,00:10:00,-t,00:00:30 postopts =

When I test with Manual.py, a HDR stream is detected: 2020-11-26 16:11:26 - MANUAL - INFO - HDR video stream detected for 0.
But the resulting output has no HDR Metadata. We can definitely see that the generated command line is missing color space, range and trc info which I think should be embedded in my file so my LG TV recognize the file as an HDR one:
Here is the FFMPEG command line that is generated : C:\Script\ffmpeg\ffmpegHDR.exe -hwaccel dxva2 -ss 00:10:00 -t 00:00:30 -i test.mkv -vcodec hevc_qsv -map 0:0 -pix_fmt p010le -vb 4363k -metadata:s:v BPS=4363000 -metadata:s:v BPS-eng=4363000 -metadata:s:v title=4K HDR -metadata:s:v handler_name=4K HDR -profile:v main10 -tag:v hvc1 -c:a:0 aac -map 0:1 -ac:a:0 2 -b:a:0 256k -metadata:s:a:0 BPS=256000 -metadata:s:a:0 BPS-eng=256000 -metadata:s:a:0 title=Stereo -metadata:s:a:0 handler_name=Stereo -metadata:s:a:0 language=rus -disposition:a:0 +default-dub-original-comment-lyrics-karaoke-forced-hearing_impaired-visual_impaired-captions -strict experimental -c:a:1 copy -map 0:1 -metadata:s:a:1 title=5.1 Channel -metadata:s:a:1 handler_name=5.1 Channel -metadata:s:a:1 language=rus -disposition:a:1 -default-dub-original-comment-lyrics-karaoke-forced-hearing_impaired-visual_impaired-captions -f mp4 -threads 0 -metadata:g encoding_tool=SMA -y C:\Script\Test\test.mp4

Can you please help me ? HW transcoding is a prerequisite for me (I accept all the downsides). Let me know if I need to use some other codec, encoder, decoder or whatever (sorry I'm a bit of a noob)
I've been looking for some help on Internet but can't even figure out if what I want to achieve is feasible.
