1 | Q1. What is this NODO document? | ||
2 | A1. This is a list if Feature Requests we get repeatedly that we simply | ||
3 | cannot do. View it as the opposite of a TODO! | ||
4 | |||
5 | Q2. Record to WAV (uncompressed) or MP3pro format! | ||
6 | A2. The recording hardware (the MAS) does not allow us to do this. | ||
7 | |||
8 | Q3. Crossfade between tracks! | ||
9 | A3. Crossfading would require two mp3 decorders, and we only have one. This | ||
10 | is not possible. | ||
11 | |||
12 | Q4. Interfacing with other USB devices (like cameras) or 2 player games over | ||
13 | USB | ||
14 | A4. The USB system demands that there is a master that talkes to a slave. | ||
15 | The Archos can only serve as a slave, as most other USB devices such | ||
16 | as cameras can. Thus, without a master no communication between the slaves | ||
17 | can take place. | ||
18 | |||
19 | If that is not enough, we have no ways of actually controlling the | ||
20 | communication performed over USB since the USB circuit in the Archos is | ||
21 | strictly made for disk-access and does not allow us to play with it the | ||
22 | way we'd need for any good communication to work. | ||
23 | |||
24 | Q5. Support MP3pro and WMA playback! | ||
25 | A5. The mp3-decoding hardware cannot do this. | ||
26 | |||
27 | Q6. Converting OGG->MP3 | ||
28 | A6. The mp3-decoding hardware cannot decode ogg. It can be reprogrammed, but | ||
29 | there is too little memory for OGG and we have no documentation on how | ||
30 | to program the MAS' DSP. | ||
31 | |||
32 | Doing the conversion with the CPU is impossible, since a 12MHz SH1 is far | ||
33 | too slow for this daunting task. | ||
34 | |||
35 | Q7. Archos Multimedia support! | ||
36 | A7. The Archos Multimedia is a completely different beast. It is an entirely | ||
37 | different architecture, differnt CPU and upgrading the software is done a | ||
38 | completely different way. We do not venture into this. | ||
39 | |||
40 | Others may do so. We do not. | ||
41 | |||
42 | Q8. Multi-band (or graphic) equalizer! | ||
43 | A8. We cannot access information for that kind of visualization from the MP3 | ||
44 | decoding harware. | ||
45 | |||
46 | Q9. Support other filesystems than FAT32 (like NTFS or ext2 or whatever)! | ||
47 | A9. No. | ||
48 | |||
49 | Rockbox needs to support FAT32 since it can only start off a FAT32 | ||
50 | partition (since that is the only way the ROM can load it), and adding | ||
51 | support for more filesystems will just take away valueable ram for | ||
52 | unnecessary features. | ||
53 | |||
54 | You can partition your Archos fine, just make sure the first one is FAT32 | ||
55 | and then make the other ones whatever file system you want. Just don't | ||
56 | expect Rockbox to understand them. | ||
57 | |||
58 | Q10. Add scandisk-like features! | ||
59 | A10. It would be a very slow operation that would drain the batteries and take | ||
60 | a lot of useful ram for something that is much better and faster done | ||
61 | when connected to a host computer. | ||
62 | |||
63 | Q11. CBR recording! | ||
64 | A11. The MP3 encoding hardware does not allow this. | ||
65 | |||
66 | Q12. Change tempo of a song without changing pitch! | ||
67 | A12. The MP3 decoding hardwar does now allow this. | ||
