FunkyBuddha Posted November 28, 2023 Share #1 Posted November 28, 2023 (edited) # Version 80.0 "Roundabout" 2023-10-29 ## New features and enhancements * MKVToolNix GUI: if the system's locale uses one of the Han scripts, the GUI will force Arabic numerals to be used in spin boxes. This prevents Suzhou numerals from being used which seems to be the default on Windows systems sold in China. Implements #3624. ## Bug fixes * build system: fixed detection of Qt6 if `clang` is used for compilation on Linux. In that case Qt's `qmake` added a `gcc`-specific option that `clang` doesn't understand, `-mno-direct-extern-access`. `configure` will now pass the parameter `-spec linux-clang` to `qmake` so that it uses the correct compiler flags. * build system: fixed the use of `mktemp` to be more portable to e.g. macOS. Fixes #3608. * mkvmerge: if a video aspect ratio was given with `--aspect-ratio-factor`, the code would apply a second factor based on the pixel resolution, resulting in much too large values for the `DisplayWidth` element. For example, with a pixel resolution of 720x520 & an aspect ratio factor of 1/1 the result should be 720x520, but instead it was 900x520. Up until release 76.0 this has only happened when a track order was given (which unfortunately includes all invocations with MKVToolNix GUI as it always includes the track order). Starting with release 77.0 this has always happened due to the automatic sorting of tracks implicitly creating a track Info: Quote Hidden Content Give reaction to this post to see the hidden content.

FunkyBuddha Posted December 7, 2023 Author Share #2 Posted December 7, 2023 # Version 81.0 "Milliontown" 2023-12-02 ## New features and enhancements * mkvmerge: MPEG transport stream reader: HEVC/H.265: added support for reading single-layer Dolby Vision from Annex B type bitstream read from MPEG transport streams. Partially implements #3113. * mkvmerge: MPEG transport stream reader, HEVC/H.265 elementary stream reader: added support for reading dual-layer Dolby Vision with both the base & enhancement layers in the same track from Annex B type bitstreams in MPEG transport files & elementary stream files. Implements #3126. * mkvmerge: MPEG transport stream reader: HEVC/H.265: implemented combining dual-layer Dolby Vision with base & enhancement layers in different tracks. Implements #3127. * MKVToolNix GUI: multiplexer: added a new option in the preferences for always enabling 'forced' subtitle tracks. A subtitle track is considered to be 'forced' if: the corresponding property is set in the source file; the track's name contains the word 'forced' (in English); deriving the 'forced display' flag from file names is active & the file name matches the corresponding pattern. The option is disabled by default. Implements #3627. * MKVToolNix GUI: multiplexer: the functionality for detecting file name sequences when adding files can now recognize the patterns used by GoPro's cameras for chaptered video files. Implements #3633. * xyzvc_dump: the end position of the current NALU will be output in non-portable format as well. * xyzvc_dump: HEVC: the tool will now also output the inner NALU type of Dolby Vision NALUs (`unspec62` and `unspec63`). ## Bug fixes * mkvmerge: when the user requests processing be stopped after the video ends `mkvmerge` will now take appending files into account properly. It won't stop processing unconditionally after the first file ends anymore. Fixes #3618. * mkvmerge: AV1 handling in readers: the readers will now provide the pixel dimensions to the AV1 packetizer as early as possible, just like for other video packetizers. That way the pixel dimensions are available for calculating the display dimensions when command-line options such as `--aspect-ratio` & `--aspect-ratio-factor` are used. Before the change the calculation was done based on initial pixel dimension values of 0x0, resulting in display dimensions of 0x0, too. Fixes #3611. * mkvmerge: HEVC/H.265 packetizer: when reading & appending HEVC/H.265 from Matroska, MP4/MOV or FLV files the first frame of all the appended files was sometimes dropped, resulting in broken video at the point where video is appended. Fixes #3479. * mkvmerge: MPEG transport stream reader: when reading MPEG transport streams from Blu-rays the four-byte long `TP_extra_header` structure in front of the transport packets are now skipped properly. Before the fix a stray byte with value of `0x47` inside that `TP_extra_header` structure could have thrown off the detection of where the transport packets start, leading to mkvmerge dropping a few audio and/or video frames at the start of the file. Fixes #3632. * mkvextract: AAC extractor: when an invalid program config element in the GA-specific config element is encountered, the program config element will be disregarded, which avoids mkvextract aborting with an exception. Fixes #3606. * xyzvc_dump: fixed the tool aborting with an exception when the last NALU in an Annex B type file was shorter than four bytes. ## Other changes * AVC & HEVC dumper development tool: the tool has been renamed from `xvc_dump` to `xyzvc_dump` as `xvc` is an abbreviation for an existing video codec (Extreme Video Coding), and the tool has nothing to do with that codec.

FunkyBuddha Posted January 5 Author Share #3 Posted January 5 # Version 82.0 "I'm The President" 2024-01-02 ## New features and enhancements * mkvmerge: Matroska reader: the "video alpha mode" track header property will be copied to the output file if present. Part of the implementation of #3643. * mkvmerge: Matroska reader: the "video alpha mode" track header property will be reported in JSON identification mode as the track property `alpha_mode`. Part of the implementation of #3643. * mkvmerge: Matroska reader: the file's timestamp scaling factor will be reported in JSON identification mode as the container property `timestamp_scale`. * mkvmerge: MPEG transport stream reader: teletext subtitles intended for hearing impaired people (type 0x05) are now marked as such via the appropriate flag in the track headers. * mkvmerge: file identification: the JSON identification output schema version has been bumped to 19. * mkvmerge: added a new hack `always_write_block_add_ids` that can be used as a workaround for players that don't support the handling of missing "Block Addition ID" sub-elements of "Block More" elements in block additions properly. These are used for e.g. alpha channel data in VP9 with a "Block Addition ID" value of 1, which is also its default value. Workaround for the player issues listed in #3643. * mkvinfo: added support for the "video alpha mode" track header element. Part of the implementation of #3643. * mkvpropedit, MKVToolNix GUI's header editor: added support for the "video alpha mode" track header property. In `mkvpropedit` it's called `alpha-mode`. Part of the implementation of #3643. * MKVToolNix GUI: multiplexer: when adding files the GUI can automatically enable the "hearing impaired" flag for audio and subtitle tracks if the file name contains the word "cc" or "sdh" delimited by certain characters (configurable). This feature is turned on by default. Implements #3648. * MKVToolNix GUI: multiplexer: when scanning for Blu-ray playlists the GUI will now ignore playlists that are likely meant for menus. Currently the GUI considers this to be the case when a playlist contains the same item at least five times. This behavior can be turned off in the preferences. Implements #3658. ## Bug fixes * mkvmerge: MPEG transport stream reader: fixed a crash introduced in v81 that occurred when there was at least one PCM track that wasn't copied from the transport stream file. Fixes #3645. * mkvmerge: when reading data from Matroska files damaged in a specific way, mkvmerge ended up trying to write various types of elements that aren't allowed to be written (so-called `EbmlDummy` elements as well as elements that don't have a value set) to the output file, which caused the underlying `libebml` library to abort. These types of broken elements are now filtered out. ## Build system changes * Qt 5 is no longer supported. Qt 6 is now required for building MKVToolNix. This implies that the options to `configure` revolving around configuring Qt 5 or choosing between the two have been removed (e.g. `--disable-qt6`). * Qt 6 detection: if detection fails, error messages from `qmake` can now be found in `config.log`. See #3649. * Qt 6 detection: `configure` will only consider Qt 6.2.0 or newer, not 6.0.x or 6.1.y anymore, due to the lack of support for the multimedia module. * Qt 6 detection: `configure` will now fail to detect Qt 6 if the 'multimedia' module is not found by `qmake` (e.g. due to development packages not being installed). See #3649. * The bundled `fmt` library was updated to v10.1.1. Info: Quote Hidden Content Give reaction to this post to see the hidden content.
