  • Q:Does our media player support both audio and video files?
  • Q:What kind of decoding library should be added?

(User:Mickey)

The S3C2410 is too slow to do video. Audio-wise, we should limit support for the most popular formats which is

  • mp3
  • ogg
  • wav.

We don't have an FM-Chip in the device, so I'm afraid we can't do .mid -- at least not in hardware. There are software MIDI players available, but I don't know whether this is interesting for us or not.

[Q]: At present, we will decide what kind of third party software for media player?

(Sean Moss-Pultz) What kind of third party software do you have in mind?

(Alex) What about RealPlayer? It has a linux version, but for mobile phone use, the performance should be taken into consideration.

(Sean Moss-Pultz) Unless we can't find a FOSS version, I would prefer not to use closed-source programs. Have a look at the follow:

[1] [2]

We should check what OPIE and GPE use. User:Mickey Can you provide some feedback here?

(Alex) GPE and OPIE both have their own media players.

  • GPE's NMF[3] is based on GStreamer[4]. NMF can play ogg and mp3 files.
  • OPIE's opie-mediaplayer2[5] It plays mp3, mpeg, wav, ogg, quicktime, divx and more. Also it is streaming capable.

[Q] In "Playback Mode" section it says "15) Panning -- realtime updated when panning wheel been rotated." The panning wheel isn't mentioned anywhere else. Is it another option for objects 5 and 6?


[Q] 12) Repeat -- Repeats the current track.
Is most player, repeat doesn't repeat the current track. It repeats the playlist (it starts playback from the beginning of the playlist after the last song in the list is played). Does this player's repeat do it differently than other players?


Q: On the repeat button as well: I'd like to see a function where it repeats the current track once and then advances in the playlist afterwards. Maybe you could have the repeat button toggle its function with each tap - e.g. repeat all -> repeat current -> repeat current once -> repeat off -> ... Abraxa 01:51, 18 February 2007 (CET)
