FS#5060 - Video implementation suggestion

I think the process of video on rockbox should be with buffering like Media Player… if you want to play at 25 FPS then you need to get to a speed that
decodes 25 full screen frames into a buffer without refreshing yet in one second
and when you start playing the video it’s like a production line
where you load the first frame in the buffer and replace it with the next from the file…

Demonstartion of a 15 Frames @ 5 FPS Video with the Buffering concept:
(copying an image from a buffer is faster than copying from a file
thus making lcd_update() work faster)

Buffer: [1] | Screen: “Loading” Buffer: [1][2] | Screen: “Loading” Buffer: [1][2][3] | Screen: “Loading” Buffer: [1][2][3][4] | Screen: “Loading” Buffer: [1][2][3][4][5] | Screen: “Loading” Buffer: [6][2][3][4][5] | Screen: [1]
Buffer: [6][7][3][4][5] | Screen: [2]
Buffer: [6][7][8][4][5] | Screen: [3]
Buffer: [6][7][8][9][5] | Screen: [4]
Buffer: [6][7][8][9]10] | Screen: [5]
Buffer: 11][7][8][9]10] | Screen: [6]
Buffer: 11]12][8][9]10] | Screen: [7]
Buffer: 11]12]13][9]10] | Screen: [8]
Buffer: 11]12]13]14]10] | Screen: [9]
Buffer: 11]12]13]14]15] | Screen: 10]
Buffer: 11]12]13]14]15] | Screen: 11]
Buffer: 11]12]13]14]15] | Screen: 12]
Buffer: 11]12]13]14]15] | Screen: 13]
Buffer: 11]12]13]14]15] | Screen: 14]
Buffer: 11]12]13]14]15] | Screen: 15]
[END]

cutbacks:
* you cant RW or FF
* it’s either a fast decoder or a larger buffer

and a larger buffer means more waiting for the video to begin
(much like on the iRiver's FW!)

You get my drift ? :)

Closing all feature requests.

Yes I Understand you. Video would be great on Rockbox. I Store all my movie files on my Ipods harddrive and that would be a very easy to to access them without having to convert them to mp4.
