We record the stream from Axis Cameras. The recordings are restarted every 15 minutes. We have one such camera that was working just fine and then several of the recordings went blank, but the audio is there. They are similar in size size to the normal recordings, so it seems something is in the file. This continued for about 3 hours and then the video came back. We have tried several video applications to see if we can recover the video track, but nothing has worked.
Can you shed any light on the issue with this file?
