【问题讨论】：
-
从您尝试传递给 FFMPEG 的文件系统路径中删除
File:/。通过一条普通的路径。 -
先生，我已经尝试过这种方式，但显示的日志相同。
storage/emulated/0/whatsappCamera/wc1529921459336.jpg -
抱歉显示
storage/emulated/0/whatsappCamera/wc1529921459336.jpg: No such file or directory -
您需要前导斜杠。文件系统路径是
/storage/emulated/0/whatsappCamera/wc1529921459336.jpg。这就是为什么我建议删除File:/，而不是File://。 -
storage/emulated/0/whatsappCamera/wc1529921459336.jpg工作！！该文件已被删除，这就是为什么它显示No such file or directory第二件事视频已创建但未显示任何内容并在 1 秒后关闭。
