Hello,
I recorded some MP4 video files with XSplit. I’m using X.264 for video and AAC LC HQ for audio.
I recently realized that some of the files are not playable. It affects SOME of the files I recorded, not all of them. I have no idea what caused it. It might have been something that happened after a successful recording.
When I open them in VLC, I don’t get an error message and the file appears to play. VLC displays a correct timeline. However, there is no video, not even a black screen - it looks like an audio file. There is also no audio playing.
I already tried fixing them with common tools such as HD Video Repair Utility from Grau GmbH and FixMP4 from Remo Software. Sadly, no success so far. I got a partial result from HD Video Repair Utility. The tool generated a file with black video but audible audio. However, the timeline was off.
I tried extracting the streams using YAMB. The audio it generates is silent. The video it extracts doesn’t even get recognized by YAMB when I re-create an MP4 using it.
I contacted http://mp4repair.org. Judging from the preview, they seem to be able to fix this. However, with about 5 hours worth of footage affected, it would be a costly repair. :confused:
I'm still looking for a simpler solution. Any procedures or diagnostic tools somebody can recommend to me?
Here are some samples:
