Rockbox Development > Feature Ideas
various feature ideas
zaphee:
Hi all. Here's a list of features that I would suggest the rockbox devs to implement.
- 3GP video support
- in oscilloscope plugin, show the detailed waveform (just like vlc's oscilloscope plugin does)
- screenshot taking plugin
- graphing calculator
- automatic battery capacity detection (if possible)
- use earphone jack as line in/mic port when recording audio (if possible)
- vorbis/mp3/wav transcoding tool
- alternate backlight brightness and timeout settings for plugins.
I know, some are more usable or feasible than others, so please don't blame me, these are just suggestions of features that I think would be useful.

You can already take screenshots - http://www.rockbox.org/wiki/ScreenDump
Rockbox also already supports using the headphone socket as an input on hardware that supports it (some ipods). Are there any devices where Rockbox doesn't implement this, but could?

3gp is a container format that can contain several codecs. For video this is h263, and most (all?) supported players are likely to be noticably too slow for this.

and how should this work? There is no button that's free all the time that could get used to trigger the screenshot. However, a screenshot functionality is already available since long. You can either use the simulator on a PC or find a menu option in the debug menu. Beware that enabling the screenshot feature in the debug menu makes a USB connection trigger a screenshot, hence you won't be able to estabilsh a USB connection anymore until you turned it off again.

This is hardware dependent. A line out is usually a line out, i.e. an output. Not an input -- that's something completely different (you need to convert an analog to a digital signal, while output is the other way round. The hardware for this is completely different).

Why? This would be slow as hell because the CPU in an MP3 player is rather limited. Transcoding is a task you really should do on a PC. But if you want to try, there's already the mp3encoder plugin which transcodes wav to mp3. It's sloooow. (Oh, and the quality of encoders on the PC is likely to be noticably better)

I actually mean the videos taken from mobile phones. I thought that some quite old mobile phones support *encoding* in this format, why wouldn't some color-screen rockbox targets just decode it ? And there's already support for some MPEG videos, as far as I know, so I suppose that targets supporting this are fast enough to decode videos with such quality ? IMHO, it's still worth trying (well, I think...).

Not a single button, but some key combination (like Select+Menu quits a plugin on an iPod, then Select+Play for example would take a screenshot when screendump is enabled, and save the picture to the player's root directory).

Which iPods ? It doesn't seem to work on my 1st-gen nano.

I think just the 4th Gen ipod and the Photo/Color. As far as we know, the 1st gen Nano hardware doesn't support it.
