问题描述
我需要帮助使用以下方法在 android 中修剪视频：'mobile-FFmpeg
我在下面发布了我的代码，我曾经用它来修剪视频，但是每次它都转到 else 块时（对于 android:11,9，每次都失败了）。 请帮帮我。 提前致谢
代码： val cmd = arrayOf("-i",trimmerData.srcPath,"-ss",startTime,"-t",endTime,"-s","320x240","-r","25","-vcodec","mpeg4","-b:v","2097152","-b:a","48000"," -ac","2","-ar","22050","-c","copy",trimmerData.dstPath)
val rc = FFmpeg.execute(cmd)
if (rc == RETURN_CODE_SUCCESS) {
Log.i(Config.TAG,"Command execution completed successfully.")
scanTrimFile(trimmerData)
} else if (rc == RETURN_CODE_CANCEL) {
Log.i(Config.TAG,"Command execution cancelled by user.")
} else {
Log.i(Config.TAG,String.format("Command execution Failed with rc=%d and the output below.",rc))
Config.printLastCommandOutput(Log.INFO)
showTrimmingError()
}
private fun scanTrimFile(trimmerData: TrimmerData) {
mediaScannerConnection = MediaScannerConnection(this,object : MediaScannerConnection.MediaScannerConnectionClient {
override fun onMediaScannerConnected() {
mediaScannerConnection.scanFile(trimmerData.dstPath,"video/*")
}
override fun onScanCompleted(path: String?,uri: Uri?) {
mediaScannerConnection.disconnect()
dismissWaitingDialog()
getResult(Uri.parse(trimmerData.dstPath))
}
})
mediaScannerConnection.connect()
}
