Use Camera as a Media Player

What about expanding the use of the camera to be able to play
1.- video files not recorded with the camera
2.- Audio files

including new codecs may be complicated, and could be memory limitations

some older cams, can use avi converted with canonavi

but new ones with 720p or 1080 , use a mov format, and check on start for duration and codecs with the .thm file

for example the mov file of the SX200is uses:

      Format : MPEG-4
      Format profile : QuickTime
      Codec ID : qt 
      Overall bit rate : 24.0 Mbps
   Video #1
      Format : AVC
      Format/Info : Advanced Video Codec
      Format profile : Baseline@L4.1
      Format settings, CABAC : No
      Format settings, ReFrames : 1 frame
      Codec ID : avc1
      Codec ID/Info : Advanced Video Coding
      Bit rate mode : Variable
      Bit rate : 23.3 Mbps
      Width : 1 280 pixels
      Height : 720 pixels
      Display aspect ratio : 16/9
      Frame rate mode : Constant
      Frame rate : 30.000 fps
      Resolution : 24 bits
      Colorimetry : 4:2:0
      Scan type : Progressive
      Bits/(Pixel*Frame) : 0.844
   Audio #2
      Format : PCM
      Format settings, Endianness : Little
      Format settings, Sign : Signed
      Codec ID : sowt
      Bit rate mode : Constant
      Bit rate : 705.6 Kbps
      Channel(s) : 1 channel
      Sampling rate : 44.1 KHz
      Resolution : 16 bits

Duration and other stuff is included in exif data in the .thm file also

I have been doing some testing and  even if you create a mov with these specs and tweak the .thm file
( I find where it specifies the seconds of durations and other stuff, but maybe not all)
it detects it and did'nt play it.

So could it be a new feature?
