Question

我正在尝试插入带有视频的音频频道：

首先，我从原始视频中提取音频进行处理：

ffmpeg -i lotr.mp4 lotr.wav
然后我提取所有帧以供以后处理：

ffmpeg -i lotr.mp4 -f image2 %d.jpg
处理完音频和视频流后，我尝试制作视频

ffmpeg -f image2 -r 15 -i %d.jpg new.mp4
然后与音频合并：

ffmpeg -i new.mp4 -i lotr.wav -map 0:0 -map 1:0 new_w_audio.mp4

结果：CPU活动= 100％，进程挂起且永不返回。 PS ：我甚至尝试过它而不修改图像或音频（所以只是尝试解压然后重新打包视频）但仍然是相同的输出

运气问题好吗？

听起来你的ffmpeg安装坏了，因为它挂起并耗费了太多的CPU。我建议完全删除它并重新开始。

祝你好运。

克里斯。
