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
Launch Replay Media Catcher. Click the “Record” button.
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.
Go to “Tools” on the program menu and select “Open Storage Folder.” The downloaded MP4 video will be accessible from this location.
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.
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."
Check the “Enable Web Downloading & Recording” box and the plug-in will be added to the Internet browsers installed on your system.
Launch an Internet browser and load the Web page with the embedded JW Player and streaming MP4 video. A "Download This Video" overlay will appear on the media.
Click the "Download This Video" button. The "RealPlayer Download & Recording Manger" will pop-up and display the file download progress. A confirmation message will appear when the process is complete. The downloaded MP4 video will be saved in the pre-selected storage location.
Launch Firefox and install the Video DownloadHelper add-on. (See Resource 3) Close the application to finalize the integration of the add-on.
Re-launch Firefox and load the Web page with the embedded JW Player and streaming MP4 video. Wait for Video DownloadHelper to recognize the media. When this happens, the add-on’s icon on the Firefox navigation bar will be animated.
Click the animated Video DownloadHelper icon and the name of the streaming video’s MP4 source file will display.
Choose the “Download” option from the fly-out menu and follow the on-screen instructions to download the MP4 video to a preferred location.
