From 09768f6f7d522045e194165249bcc88a5f38398d Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Thu, 16 Jan 2003 16:06:31 +0000 Subject: added the NODO document git-svn-id: svn://svn.rockbox.org/rockbox/trunk@3111 a1c6a512-1295-4272-9138-f99709370657 --- docs/NODO | 67 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 docs/NODO (limited to 'docs/NODO') diff --git a/docs/NODO b/docs/NODO new file mode 100644 index 0000000000..d9e91045e1 --- /dev/null +++ b/docs/NODO @@ -0,0 +1,67 @@ +Q1. What is this NODO document? +A1. This is a list if Feature Requests we get repeatedly that we simply + cannot do. View it as the opposite of a TODO! + +Q2. Record to WAV (uncompressed) or MP3pro format! +A2. The recording hardware (the MAS) does not allow us to do this. + +Q3. Crossfade between tracks! +A3. Crossfading would require two mp3 decorders, and we only have one. This + is not possible. + +Q4. Interfacing with other USB devices (like cameras) or 2 player games over + USB +A4. The USB system demands that there is a master that talkes to a slave. + The Archos 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 ways of actually controlling the + communication performed over USB since the USB circuit in the Archos 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. + +Q5. Support MP3pro and WMA playback! +A5. The mp3-decoding hardware cannot do this. + +Q6. Converting OGG->MP3 +A6. 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 12MHz SH1 is far + too slow for this daunting task. + +Q7. Archos Multimedia support! +A7. The Archos Multimedia is a completely different beast. It is an entirely + different architecture, differnt CPU and upgrading the software is done a + completely different way. We do not venture into this. + + Others may do so. We do not. + +Q8. Multi-band (or graphic) equalizer! +A8. We cannot access information for that kind of visualization from the MP3 + decoding harware. + +Q9. Support other filesystems than FAT32 (like NTFS or ext2 or whatever)! +A9. No. + + 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 filesystems will just take away valueable ram for + unnecessary features. + + You can partition your Archos fine, just make sure the first one is FAT32 + and then make the other ones whatever file system you want. Just don't + expect Rockbox to understand them. + +Q10. Add scandisk-like features! +A10. 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. + +Q11. CBR recording! +A11. The MP3 encoding hardware does not allow this. + +Q12. Change tempo of a song without changing pitch! +A12. The MP3 decoding hardwar does now allow this. -- cgit v1.2.3
