[M4IF Technotes] HD decoders?

[trbarry trbarry.com]

Why not just download Divx or Xvid, both free MPEG-4 encoders. Either of
them can create these files from most any PC file sources, though
playing 1080p at full speed is probably hard.

| I've once done this experiment for fun with the MPEG-4 codec
| of QuickTime
| (for a test sequence of 600 frames with a resolution of 1280x720, YUV
| 4:2:0). It worked but I don't want to know all the rules I

| then ;-). The only thing you have to worry about is getting the YUV

| guess there are also other solutions.
|
| The reference software for H.264/MPEG-4 AVC should also be
| able to deal
| with that.
