MKVToolNix v81.0.0 Final x86/x64 多语言中文正式版-MKV封装工具下载

MKV 是一种优秀的多媒体容器格式，它可把多种不同编码的视频及16条或以上不同格式的音频和语言不同的字幕封装到一个 MKV 文件中，而 MKVToolNix 是一款免费开源的 MKV 编辑器和工具集，能够合成、编辑 Matroska MKV 文件。

MKVToolNix 包含了以下几个 MKV 专用处理工具：
*mkvmerge：将多媒体文件封装、合并、混流为 MKV 文件；
*mkvinfo：输出 MKV 文件组件和编码信息；
*mkvextract：从 MKV 文件中提取视频、音频和字幕轨道；
*mkvpropedit：直接修改现有 MKV 文件的属性而无需重混流；
*mmg：mkvmerge GUI，并包含了章节编辑器和头部编辑器。

MKVToolNix 中的 Mkvmerge GUI 允许你导入多个视频、音频、字幕轨道，混流合并一个新的 MKV 文件，并可以设置导出视频的宽高比、显示比例、帧频等等。

MKVToolNix 中的 MKVExtractGUI 则可以从现有的 MKV 文件中提取其中的一个或多个视频、音频或者字幕信息，是专业的 MKV 分离工具。

MKVToolNix 是专用的 MKV 剪辑工具，分享了4种 MKV 切割模式，包括按尺寸、按时长、按特定时间码和按分段，都是无损剪辑、分割 MKV 过程，能够同步切割视频、音频和字幕轨道。比之前介绍的所有支持 MKV 分割的工具都要好用，包括 Boilsoft Video Splitter、SolveigMM AVI Trimmer 等。

# 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.
