Fixing corrupt server-side recordings

Fixing corrupt server-side recordings

Occasionally, a video recording from a live stream in DEVOS will not function properly. The result is a video that appears to be 1193:02:47.295 in duration. The video does not play properly in DEVOS, and the viewer cannot scroll forward or backwards in the video to watch a specific part.

While Discover Video engineers are actively working to prevent this from happening, it is now possible to fix the recorded file so that it plays properly, and you do not lose any content due to this problem. The fix requires a free tool called Avidemux which can be downloaded from this link:

Depending on your computer, download the appropriate version. Once installed, follow the steps below to repair and replace the file.

1. Open the file in Avidemux.
2. Make sure the outputs are both set to "Copy" and the format is set to MP4 Muxer as shown here:

3. Click the button that the mouseover command says "Go to last frame [END]" as the arrow is pointing to below.

4. You should see the actual end of the video time in the time window as shown above.

5. Now, click on the B end point button that the arrow is pointing to below.

6. You should see the time for the end point change in the lower right corner as shown below.

7. Now simply save the edited file from the File menu as an MP4 file.

This procedure resets the mov atom that defines to the player the duration of the video and makes it play properly in DEVOS once the new video is uploaded. If you would like, you can also use the video replacement tool found on the DEVOS help page to simply replace the existing video with the repaired video so that you don't have to make a whole new VOD listing. That tool can be downloaded here:
