Make this info available for all bitmap targets, also ones that only need it in the pictureflow description. Shuffle some lines around so that it doesn't need too many opts. Fixes FS#11350. Change-Id: I5268483c7a1d765c8a994614442309b05de1d832

\section{Bug reports}
|
|
If you experience inappropriate performance from any supported feature,
|
|
please file a bug report on our web page. Do not report missing
|
|
features as bugs, instead file them as feature ideas (see below).
|
|
|
|
For open bug reports refer to
|
|
\url{http://www.rockbox.org/tracker/index.php?type=2}
|
|
|
|
\subsection{Rules for submitting new bug reports}
|
|
|
|
\begin{enumerate}
|
|
\item Check that the bug has not already been reported
|
|
\item Always include the following information in your bug report:
|
|
|
|
\begin{itemize}
|
|
\item Which exact \dap{} you have.
|
|
\item Which exact Rockbox version you are using
|
|
(Menu $\rightarrow$ System $\rightarrow$ Rockbox Info $\rightarrow$ Version)
|
|
\item A step{}-by{}-step description of what you did and what happened
|
|
\item Whether the problem is repeatable or a one{}-time occurrence
|
|
\item All relevant data regarding the problem, such as playlists, MP3
|
|
files etc. (IMPORTANT!)
|
|
\end{itemize}
|
|
\end{enumerate}
|

\section{Feature ideas}
|
|
To suggest an idea for a feature or to read those made by others, see
|
|
\url{http://forums.rockbox.org/index.php?board=49.0}. Please keep in
|
|
mind that this forum is for the discussion of feature ideas - they are not
|
|
requests and there is no guarantee they will be acted upon.
|
|
|
|
\subsection{Rules for submitting a new feature idea}
|
|
|
|
\begin{enumerate}
|
|
\item Check that the feature has not already been suggested.
|
|
Duplicates are really boring!
|
|
\item Check that the feature has not already been implemented.
|
|
Download the latest current/daily build and/or search the mail list archive.
|
|
\item Check that the feature is possible to implement (see \reference{ref:NODO}).
|
|
\end{enumerate}
|
|
|
|
\subsection{\label{ref:NODO}Features we will not implement}
|
|
This is a list of Feature Requests we get repeatedly that we simply
|
|
cannot do. View it as the opposite of a TODO!
|
|
|
|
\begin{itemize}
|
|
\opt{archos}{
|
|
\item Record to WAV (uncompressed) or MP3pro format.\\
|
|
The recording hardware (the MAS) does not allow us to do this
|
|
\item Crossfade between tracks.\\
|
|
Crossfading would require two mp3 decoders, and we only have one.
|
|
This is not possible.
|
|
\item Support MP3pro, WMA or other sound format playback.\\
|
|
The mp3{}-decoding hardware can only play MP3. We cannot make it play other
|
|
sound formats.
|
|
\item Converting OGG $\rightarrow$ MP3.\\
|
|
The mp3{}-decoding hardware cannot decode OGG. It can be reprogrammed, but
|
|
there is too little memory for OGG and we have no documentation on how to
|
|
program the MAS' DSP. Doing the conversion with the CPU is impossible, since
|
|
a 12~MHz SH1 is far too slow for this daunting task.
|
|
\item Archos Multimedia support.\\
|
|
The Archos Multimedia is a completely different beast. It is an entirely
|
|
different architecture, different CPU and upgrading the software is done
|
|
a completely different way. We do not wish to venture into this. Others
|
|
may do so. We will not.
|
|
\item Multi{}-band (or graphic) equaliser.\\
|
|
We cannot access information for that kind of visualisation from the MP3
|
|
decoding hardware.
|
|
\item CBR recording.\\
|
|
The MP3 encoding hardware does not allow this.
|
|
\item Change tempo of a song without changing pitch.\\
|
|
The MP3 decoding hardware does not allow this.
|
|
\item Graphic frequency (spectrum analyser).\\
|
|
We cannot access the audio waveform from the MP3 decoder so we cannot analyse
|
|
it. Even if we had access to it, the CPU would probably be too slow to
|
|
perform the analysis anyway.
|
|
\item Cool sound effects.\\
|
|
Adding new sound effects requires reprogramming the MAS chip, and we cannot
|
|
do that. The MAS chip is programmable, but we have no access to the chip
|
|
documentation.
|
|
}
|
|
\nopt{iriverh300,iaudiox5}{
|
|
\item Interfacing with other USB devices (like cameras) or 2 player games over USB.\\
|
|
The USB system demands that there is a master that talks to a slave. The
|
|
\dap{} can only serve as a slave, as most other USB devices such as
|
|
cameras can. Thus, without a master no communication between the slaves
|
|
can take place. If that is not enough, we have no way of actually
|
|
controlling the communication performed over USB since the USB circuit
|
|
in the \dap{} is strictly made for disk{}-access and does not allow us
|
|
to play with it the way we'd need for any good communication to work.
|
|
}
|
|
\item Support other file systems than FAT32 (like NTFS or ext2 etc.).\\
|
|
No.
|
|
\opt{archos}{Rockbox needs to support FAT32 since it can only start off a FAT32
|
|
partition (since that is the only way the ROM can load it), and adding}%
|
|
support for more file systems will just take away valuable ram for
|
|
unnecessary features. You can partition your \dap{} fine, just make sure
|
|
the first one is FAT32 and then make the other ones whatever file system
|
|
you want. Just do not expect Rockbox to understand them.
|
|
\item Add scandisk{}-like features.\\
|
|
It would be a very slow operation that would drain the batteries and
|
|
take a lot of useful ram for something that is much better and faster
|
|
done when connected to a host computer.
|
|
\item Alphabetical list skipping.\\
|
|
Skipping around the lists by jumping letters (i.e skip all C's and go
|
|
straight to the first D). This isn't feasible with the current list
|
|
implementation, if you really want this you can get similar effects using
|
|
the database (see \reference{ref:database}).
|
|
\item Add support for non standard tag formats.\\
|
|
APE tags in MP3 files has been rejected a few times already. Its not something we want.
|
|
\item Implementing the ability to playback DRM files.\\
|
|
Firstly, this would be extremely difficult to implement legally - Rockbox
|
|
is not legal entity as such, and therefore is unable to enter into license
|
|
agreements with providers of DRM technology.
|
|
Secondly, Rockbox is open source, which would mean that any DRM technology we
|
|
incorporated into our codebase would suddenly become visible to the whole world,
|
|
completely defeating its purpose. Remember, DRM achieves part of its security
|
|
through obscurity, and publishing the keys necessary to decrypt DRM'd
|
|
media would essentially render it useless.
