20221121将行车记录仪记录的MJPEG格式的AVI片段合并的MKV转换为MP4
2022/11/21 21:51

（一）
缘起，用行车记录仪录制的爬拉胡线（惠州大南山）的AVI视频，一个片段5分钟。
使用mkvtoolnix-gui将AVI合并成为MKV视频之后：20221113惠州拉胡线2-DCIM-MOVI0000.mkv
"D:\Program Files\MKVToolNix\mkvtoolnix-gui.exe"

由于剪映只能识别最多2小时的视频的机器字幕。
但是使用PR2003不认识直接生成的MKV，需要使用ffmpeg转换mkv视频为mp4了。

文件导入失败：
错误信息
文件的压缩类型不受支持。

使用 FFmpeg 从 mjpeg 转换为 mp4 (libx264)

如果使用 FFmpeg 从 mjpeg 转换为 mp4 (libx264)，则无法在 Windows · Mac 上进行播放。
图标上不显示缩略图。但是，使用 HTML5 Video 标签，播放是可能的。
为什么？如果你明白，请告诉我。谢谢你。
ffmpeg -i source_file.mov -b 4000k -vcodec libx264 destination_file.mp4

通常的原因是像素格式。MJPEG 可能有 4:2:2 或 4:4:4 色度采样，大多数播放器在 H264 中不支持。所以试试
ffmpeg -i source_file.mov -pix_fmt yuv420p -b:v 4000k -c:v libx264 destination_file.mp4

 

 

【不修改码率，如果需要修改码率，请使用参数：-b 4m/-b:v 4M】
ffmpeg -i 1.mkv -vcodec libx264 1.mp4
ffmpeg -i 20221113惠州拉胡线2-DCIM-MOVI0000.mkv -vcodec libx264 20221113惠州拉胡线2-DCIM-MOVI0000.mp4

3小时的视频需要1小时49分钟。
（大致需要你需要转换的视频时长的2/3）
