may be I should split this into its won issue ("Support tsmuxer as alternative to bdwrite")? At least I looked again at tsmuxer git and found there https://github.com/justdan96/tsMuxer/commit/330bb477cc4290248c90c6787fcd83aadc0c50f9 "Support for HDMV descriptors is now selectable at runtime" in description it says: "--hdmv-descriptors Use HDMV descriptors instead of ITU-T H.222.0 | ISO/IEC 13818-1 descriptors. Activated automatically for BD muxing." Note there is gui (Qt) and console version of this utility, I think console one can be used without much effort? |

little update - it seems https://github.com/justdan96/tsMuxer/commits/master constantly get fixes for UHD/HDR blu-rays .... So if original reporter still around - may be retesting this specific muxer while using CinGG just for encoding will help to find out if there is already working open-source support for at least this stage (muxing to iso file) of BD creation, even if not yet integrated in CinGG itself? |

actually, mpegts.h from ffmpeg already uses #define STREAM_TYPE_VIDEO_HEVC 0x24 |

additional info recently open-sourced tsMuxer has some support for UHD muxing, bug bugs exist https://github.com/justdan96/tsMuxer https://forum.doom9.org/showthread.php?t=176668&page=4 (info relative to tsMuxer's sources) ----------- Hi all, before all I thank the tsMuxer developer for his fantastic software, and for accepting to release the source code. Quote: Originally Posted by jdobbs View Post it misses frames, or more accurately it thinks some frames are a part of a previous frame and muxes them as a part of it. The result is a stream that gets progressively more out of sync (at least those that are encoded for blu-ray UHD by X265) There is a bug creating unsynchronized AV with some HEVC files, due to insufficient size of coded picture buffer. In brief, when reading a nal the end of the buffer is reached before finding the next nal start_code, and the PTS is not incremented for this nal. (Edit: correction changed) I have corrected the bug on my side by simply changing the line 7 in avPacket.h from: Code: const static int MAX_AV_PACKET_SIZE = 32768; to Code: const static int MAX_AV_PACKET_SIZE = 800000; I am not a developer and have limited coding knowledge, so I won't submit a patch. ---------------- and ---------- Quote: Originally Posted by jdobbs View Post It also uses the wrong stream type Replace lines 41 and 42 in tsPacket.h Code: //static const uint8_t STREAM_TYPE_VIDEO_H265 = 0x24; static const uint8_t STREAM_TYPE_VIDEO_H265 = 0x06; with Code: static const uint8_t STREAM_TYPE_VIDEO_H265 = 0x24; // static const uint8_t STREAM_TYPE_VIDEO_H265 = 0x25; /* HEVC conforming to profile */ Edit note: should normally be 0x25, but seems to be 0x24 in UHD Blu-rays --------- |

Update: so that this does not get lost, when looking for a possibility refer to Andrew's email of Fri, Feb 15, 5:29 PM (2019) which will be archived in PiperMail with the title of: "In support of issue 0000120 (UHD blu-ray encoding/mastering)" It could be the key to a future resolution. |

MatN: Unfortunately uhd standards for bluray seem to be proprietary. I spent a lot of time searching for definitive documentation but all of the bits and pieces added up to nothing usable. Terje did a lot of research and provided a lot of links back in 2017 to hopefully get this going. We need something like we used to get bluray built initially. This consisted of pieces from VLC libbluray + an actual iso file that we dug up for the blender project Sintel 2010 at: http://download.blender.org/durian/movies/ That was the key piece and we would need similar types of libraries and media iso to get udh to work. |

Maybe HEVC is required for 25p ? https://en.wikipedia.org/wiki/Blu-ray#Video |
