I was asked to create a video player from scratch, so I think I'm missing some parts of the whole story. For an mp4 file containing this information, what boxes should I be concerned about in order to play the streams within the file. I know I should follow the standard and so on, but what I did is that I messed up the file a little bit. I transmuxed the video/audio streams like this:
h264 -> mjpeg || AAC -> mp3
For the sake of simpler decoding "since I'm writing everything from scratch"
this is the info about the video track in the mp4 file I'm trying to support:
