MP4 Video Problem：
A 17 Gig corrupted video, it was recorded on a windows 10 laptop. The power shut the computer down and user couldn’t stop recording and save the video. The video was there but can not be played with any media player. The video is about 3 hours, the user need it to be repaired.
What we can do:
In this case, because the recording was interrupted, the header or footer of the video is missing, media player can not decode the video file without the key section. What we can do is rebuilding correct header or footer for the video file, to make sure the video and audio keep synced, we also need to do more work for the repairing. The 17G MP4 video file was repaired after our hard work.
