[pt75000]

Hello, someone could tell me how is it possible to download Alphorm Videos ?

The link is about that :

rtmpte://rtmp.alphorm.com/cfx/st/mp4:FR_291/FR_291_03_01.mp4?Expires=1458094924&Signature=mBOM-ywFXZxSMvfz-vEywgQcMq4BXFgKUVBMI3h0ddb9xkQSOZYFOB4JN81IySETUuu 6H1cx3D62sUM77GVo0RQGHGpMsPDzCnTzWlyk8mgS3qMiX-NPQRMRKGc1JpxqOBOCXjoj8cLr6fyWepw9LQn0-y6fk7pGuhbkG-OUzLU_&Key-Pair-Id=APKAJF2PMCJPGKXG2GEA

or that :

I tried with rtmpdump.exe but ERROR: RTMP_Connect1, handshake failed.

I tried with VLC (open stream) : but error

I Tried with Jaksta but error too :

I tried with "URLSnooperSetup" but it does not detect the stream !

I think the video are protected but i dont know how ?

For exemple if i use an api rest program :
URL : http://www.alphorm.com//formation/PlayVideo
Method : Post
Header : Content-Type: application/json
Content : {'idVideo':4843, 'idtraining':113}

The Api returns me :

{
"success": {
"TrainingId": 113
"VideoId": 4843
"PathVideo": "FR_226/FR_226_04_00.mp4?Expires=1458094881&Signature=sDKy us4gaCvZ2c4yfORz2RuUxERkgtXVFjcC5lBqUBqB4kpVUMgnJH TxG1TS2a0WCQfz~VFCVSjc6eQQCFdHZkbuo3QUx2ngJnXRmSMS vJgtwLr8uEvSeK84q~bX25ryqcBgVRynkGCX3uxnNYC1gBX47U YtD55bm7N7S~3MONM_&Key-Pair-Id=APKAJF2PMCJPGKXG2GEA"
"PathStVideo": ""
"LastPosition": 0
"TrainingPhoto": "http://static.alphorm.com/bgplayer/FR_226_bg_player.png"

}-

}

What the technic did they use ?

Thank you for your help !
