Hello,
have a question. If source is HDR10+ and i dont specify --dhdr10-info with x265, do I get correct HDR10 video? In other words, difference between HDR10+ and HDR10 is only SEI metadata and result playback is the same whether they are not present or player can not use them? Thanks a lot. |

I hope this is correct thread for my question. I have issues with parsing hdr10+ metadata from some mkv files using ffmpeg+hdr10plus_parser.
First, when I run the verification I get this which looks promising: ←[34mParsing HEVC file for dynamic metadata... ←[0m ←[34mDynamic HDR10+ metadata detected.←[0m But then when I start the parsing it stops at some point and I get this: ←[34mParsing HEVC file for dynamic metadata... ←[0m frame=193656 fps=864 q=-1.0 Lsize=36697460kB time=02:14:37.02 bitrate=37219.8kbits/s speed= 36x video:36697460kB audio:0kB subtitle:0kB other streams:0kB global headers:1kB muxing overhead: 0.000000% ←[34mReading parsed dynamic metadata... ←[0mthread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Parse("not enough data: expected 12 bits got 2 bits")', src/hdr10plus/parser.rs:233:71 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace I have to say that with my limited understanding on these things I have no idea what is the issue here. Well, it says something about "not enough data" but what does that mean? Is there anything I can do to get the HDR10+ metadata out of these file? This is the command line I'm using: ffmpeg -i input.mkv -c:v copy -vbsf hevc_mp4toannexb -f hevc - | hdr10plus_parser -o metadata.json - |

Then I would have another issue in regards to HDR10+ metadata. When I try to encode one file using FastFlix it immediately stops and the following lines can be seen in the log. If I encode the same file without the HDR10+ metadata then it works. What could be wrong with the metadata? INFO x265 [error]: Unable to open tone-map file. INFO [libx265 @ 0000020444ccdec0] Cannot open libx265 encoder. INFO Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height INFO Conversion failed! INFO INFO WARNING Error during conversion |

FastFlix supports using generated or extracted JSON HDR10+ Metadata with HEVC encodes via x265. However that is highly dependant on a FFmpeg version that has been compiled with x265 that has HDR10+ support. BtbN's Windows FFmpeg builds have this support as of 10/23/2020 and may require a manual upgrade.

There are example files in the x265 repo: https://bitbucket.org/multicoreware/x265_git/downloads
Not all the fields are used in the x265 code, however.

Hello quietvoid,
and thanks again for your amazing work in developping this metadata parsing tools. I've seen that you've recently updated the HDR10+ parsing tool with the similar principle than for the dovi one : does it have a "crop" option as well to be activated? Or as it should only concern the "active area", according to the official documentation, it is no problem to transcode with cropped bars?

You'll need manually set the metadata to the same as the source if using standard x265.exe. |

Thx. Speaking of which, seems DGindexNV already tags a line to its .dgi files, like Code:
X265_CL --colorprim 9 --transfer 16 --colormatrix 9 --master-display "G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(40000000,50)" --max-cll "10000,724" --frames 181104 --chromaloc 2

Well, thank you kindly for that request. Saves me a ton of work trying to figure it out each time. And thanks be to Don, of course, for adding it.
