对于腾讯视频，若为mp4格式(多为iOS设备提供)方法同上，若为ts格式(多为云视听极光提供)的杜比视界，则参考此评论的做法。 下载eac3to并解压至 以《芳华》为例，使用下载器下载结束后，得到 使用eac3to抽取视频流和音频流： 然后使用mp4muxer进行封装即可： 封装耗时根据不同片源大约需要1~30分钟不等 等待封装结束即可看到成品 |

现在腾讯新出的杜比视界好像混流阶段卡很久很久都没结果，比如刚出的 门锁 ，抽取都正常，在混流阶段不出结果了.. |

mp4muxer混流好像很慢，直接用是ffmpeg5更快 |

某些TS封装使用 脚本替换如下： for /l %%i in (1,1,60) do (
ffmpeg.exe -i %%i.ts -map 0:a -c copy %%i.aac && ffmpeg.exe -i %%i.ts -c:v copy -vbsf hevc_mp4toannexb -f hevc %%i.hevc && mp4muxer -i %%i.hevc -o %%i_tmp.mp4 --dv-profile 5 --overwrite && mp4box -inter 500 -add 1_tmp.mp4:name= -add %%i.aac#trackID=1:name=:lang=chi -itags tool="libav":cover="标题.jpg":title="标题 (2021)" %%i.mp4 && del %%i.ts && del %%i_tmp.mp4 && del %%i.hevc && del %%i.aac

https://github.com/DolbyLaboratories/dlb_mp4base/tree/master/bin mp4muxer更新后支持设置mp4的flag（苹果设备只认dvh1/hvc1） 也可以通过该项目设置：https://github.com/rixtox/mp4dovi |

概览 视频 音频 我有一个VFR格式的视频，无法使用mp4demuxer进行封装，使用mp4box对视频进行了剪切，请问如何在不重新编码的情况下封装视频啊，主要是我这个视频在电脑和手机上都能识别但是上传B站会被降级为HDR，很奇怪，CBR就没有这个问题 |

所需软件：
mp4demuxer：https://github.com/DolbyLaboratories/dlb_mp4demux/tree/master/bin
mp4muxer：https://github.com/DolbyLaboratories/dlb_mp4base/tree/master/bin
以优酷视频《“大”人物》举例。
使用N_m3u8DL-CLI下载完成后，得到两个mp4文件，分别为
“大”人物_01.45.42_mp5hd3v3vision_atmos.mp4、“大”人物_01.45.42_mp5hd3v3vision_atmos(Audio).mp4将视频命名为
video.mp4，将音频命名为audio.mp4由于mp4muxer不直接支持mp4封装混流，所以需要先使用mp4demuxer提取音视频流再进行封装：
执行结束后，得到
out_1.h265、out_1.ec3使用mediainfo观察Dolby Vision版本情况：
Dolby Vision, Version 1.0, dvhe.05.03, BL+RPU则需使用--dv-profile 5参数然后使用mp4muxer进行封装即可：
封装耗时根据不同片源大约需要1~30分钟不等
等待封装结束即可看到成品
