{HttpStatus: 500, errorCode: 352, errorType: FacebookApiException, errorMessage: Sorry, the video file you selected is in a format that we don't support.}

I don't know what I am doing wrong, but every time I get this error. is there any other way to post video on facebook wall. I know how to post a newUploadVideoRequest video , but in my case I don't want to download the video and save it to SD card and then post to facebook. There is another way that I can call the api url graph and post the video to facebook wall, but is there any other method so I can post video to facebook wall directly , I almost link to every link
