I just recorded about 6 hours of AAC streaming into a file, resulting in 300 MB approximately. The file doesn't play. I wonder if there was any problem with the file format and content, or it is just the size of the file. If the latter, I wonder if I could split the file. If the former I wonder if I could fix this problem somehow or obtain more info about the data so I can troubleshoot.
The problem is that I didn't hit the Stop button on VLC. If the conversion is paused or interrupted the generated file becomes invalid.
One way to recover the file is to resume the conversion and then hit stop.
