更新-
按照@slhck 的建议更新 ffmpeg 并尝试 @Gyan 建议的命令（略作修改）后，ffmpeg -f h264 -r 15 -i 0x5C3C3031.raw -c copy output_3031.avi我得到了不错的 avi 视频。但是，输出的持续时间比预期的持续时间要短一点。原始视频应该为 10:54 长，但此处的输出为 9:54 长。我将帧速率指定为 15（我正在将时间与官方提供的工具转换的视频进行比较，这些视频的帧率为 15 fps）。此外，在我尝试的另一个较大的文件上，输出应该为 59:53 长，但实际为 57:41。以下是命令的输出ffmpeg -f h264 -r 15 -i 0x5C3C3031.raw -c copy output_3031.avi-

这不是原始的。它是 AVC，即 H.264 附件 B。看起来像附件 B，因为从这个https://stackoverflow.com/questions/51353973/what-is-different-between-h-265-hevc-in-a-containermp4-mkv-and-h-265-hevc你可以看到它插入了 0x000001，可以被识别为 NAL 单元 0，要将其解码为经典 avc，你需要使用 ffmpeg，因为它只有 h264_mp4toannexb 和不h264_annexbtomp4，但这里有一个https://github.com/ireader/media-server/commit/76e62c806aaa5e1f97c626a52df0b03c2b2b47b1附件 B 问题在此处https://trac.ffmpeg.org/ticket/8781
此外，ffmpeg 2.8.15 版本太旧了，这太疯狂了。
