Any media file experts out there… if so, I have a video file question.
I have a video file which has an .mp4 file extension. Analysing this file with file recognition software tells me that the container for this file is MPEG -2 Program Stream, which I understand is a high quality, uncompressed format, such as used for DVD streams (correct me if I’m wrong here!).
Now, considering the same piece of software states that this same video is encoded with the H264 codec, which I thought generally only worked with compressed files (again, correct me if I’m wrong), can the file recognition software be correct?
Being that the file extension is an mp4 and the codec is H264, this would suggest that the file has been compressed? If that’s the case, I can’t understand how it identifies it as an MPEG-2 Program Stream as that should be uncompressed?
Hope that makes sense?
Any observations would be interesting!
