How to Download a Streaming MP4 RTMP With a JW Player

JW Player is an open-source framework for streaming video over RTMP, a protocol that is specialized to transfer media on the Internet. If a JW Player is streaming video in the MP4 format, you can use a few tools to download the media. Replay Media Catcher, RealPlayer and Video DownloadHelper, a Firefox add-on can all be used for this task.

Replay Media Catcher

Step

Launch Replay Media Catcher. Click the “Record” button.

Step

Launch an Internet browser and load the Web page with the embedded JW Player and streaming MP4 video. The application will recognize the media and record the video stream. A “Completed” message will appear when the downloaded MP4 video is available.

Step

Go to “Tools” on the program menu and select “Open Storage Folder.” The downloaded MP4 video will be accessible from this location.

RealPlayer

Step

Launch RealPlayer. Open the “RealPlayer” drop-down menu on the program toolbar. Select “Preferences…” and a popup window will appear. Select the “Download & Recording” entry under the “Category” menu.

Step

Click the “Browse” button alongside the “Save Files to” field. A “Browse for Folder" pop-up window will appear. Select a storage location for downloaded video and click "OK."

Step

Check the “Enable Web Downloading & Recording” box and the plug-in will be added to the Internet browsers installed on your system.

Video DownloadHelper
