最新版本4.9.0 拼接2个.mp3的音频文件（试了很多文件），最终文件时长是两个音频的长度，但内容只有第一个音频的内容
fishforest opened this issue · comments
拼接代码：
var file1 = File(activity?.getExternalFilesDir(null), "lili.mp3")
var file2 = File(activity?.getExternalFilesDir(null), "hh.mp3")
var sb = StringBuilder()
sb.append(file1.absoluteFile)
sb.append("|")
sb.append(file2.absoluteFile)
var targetPath = File(activity?.getExternalFilesDir(null), "target.mp3")
var list = RxFFmpegCommandList().apply {
append("-i")
append("concat:$sb")
append("-acodec")
append("copy")
append("${targetPath.absolutePath}")
}.build()
拼接的命令为：
调用拼接方法
RxFFmpegInvoke.getInstance().runCommand(list, object : RxFFmpegInvoke.IFFmpegListener {
override fun onFinish() {
println("rx finish")
}
override fun onProgress(progress: Int, progressTime: Long) {
println("rx onProgress:$progress")
}
override fun onCancel() {
println("rx onCancel")
}
override fun onError(message: String?) {
println("rx error:$message")
}
})
回调打印了finish，没有报错误。
