FS#9787 - iPod 5G TV out
Opened by Boris Gjenero (dreamlayers) - Monday, 12 January 2009, 07:05 GMT
Here is a preliminary patch for TV out on a 5th generation iPod. Play a BMP file and TV out will activate. NTSC is the default. If the file has 576 lines, the output will be in PAL. The image stays until another is loaded or TV output is disabled via the debug menu..
The following formats ought to work:
720x480, 24 bpp for NTSC
720x576, 24 bpp for PAL
Many programs including Windows Paint and ImageMagick convert can write such files. Other resolutions and bit depths may work. For example WPS background screens display properly but other WPS bitmaps don't.
- More work needs to be done to integrate this with Rockbox. No, you cannot view the Rockbox interface, JPEGs or mpegplayer output yet.
- When the LCD is updated, there is a temporary disturbance on TV output
- http://en.wikipedia.org/wiki/Macrovision#Analog_copy_prevention is enabled. Yes, the hardware can disable it, but I haven't figured out how to do that yet.
- The original firmware probably outputs images differently. It can load programs into the BCM which perform decoding there, and that is probably faster.
