Hello everybody! Happy New Year)
I have a seious problem. We had a conference at the university two weeks ago, and I recorded it on the web-camera with the help of VLC Player. I set the output format to video h.264, audio aac, container MP4. The event lasted about 4 hours.
When it was over, I pressed Stop and closed the application. As I learned afterwards, I had to wait for about 1 minute for the writing process to stop actually (perhaps because of some buffer). But then I didn't know about it and closed the program, it didn't show any message. And the highly valuable file remained unfinished, without headers and probably without the ending. The ending is not so important, but without headers I cannot open it with any program!
So, I decided to ask for your help, because no one knows the format and writing algorithm better than you. Could you help me some way to repair my video? Or just tell about the headers that VLC writes in MP4 and their purpose?
I opened the recorded file in WinHEX, opened another file that is longer (about 6 hours) and tried to "transplant" the missing beginning from the normal video. The file opened correctly in most players, the length was equal to the length of the normal file, but all that I could see was the black screen and absolute silence. I guess that there must be some matrix that helps the player to read audio and video fragments correctly. Could you help me to reconstruct it? Or advise some program that can do it automatically?
