Question

我使用以下命令覆盖jpg：

ffmpeg -i in.mp4 -vf＆＃34; movie = bb.png [movie]; [in] [movie] overlay = 0：0 [out]＆＃34; -vcodec libx264 -acodec copy out.mp4

这与第一个文件（如下所列）一样正常工作，但它不适用于第二个文件。当我尝试使用第二个文件时没有错误，而是创建一个无法打开的异常大的文件：

如果重要的是我使用Android设备捕获这些视频。第一个mp4文件由Nexus 7创建，第二个（不会覆盖图像的文件）是使用HTC Desire创建的。

Answer 1

也许是另一个命令先生

ffmpeg -i in.mp4 -i bb.png -filter_complex overlay -c:a copy out.mp4
