Android 上的 FFMProbe 输出

Question

如何在 FFMPegKit 上执行并获取 FFMProbe 命令的输出？我尝试了各种方法。但我失败了。请问有人可以帮我吗？

Answer 1

几天后，我成功了（虽然提问和回答的时间是一样的，但我之前已经尝试过多次了）。

FFprobeKit.executeAsync("-v error -show_streams -print_format json videopath") { session ->
        Log.d("TAG", "fileDetails: FMProbe output: ${session?.output}")
    }

此 Log.d 将输入视频的详细信息打印为 JSON（作为命令）。
