[C] [RELEASE] MP3 ME Player v1.02

[caliarbor]

Hi Everyone,

Haven't tested this on 4.01 yet as my slim is still 3.90m33-3. The screenshot looks a little crooked for some reason. I'm going to have to try a different plugin. Here's the readme.txt included :: (sorry for the wall of text crit)

Slight change increases heap size, doesn't check for cover art being greater than 170x170, and instead of only showing info of playing track shows info of highlighted track in browser

MP3 ME Player v1.02

MP3 player that makes use of the PSP's Media Engine. CPU is clocked at 39MHz to allow for longer
playback from battery.

Changes:

Added an asterisk in front of the current playing track in the browser pane. While the tracks is playing it will be green. If paused it will be yellow. Once the track is completed it will go to red.

Dropped USB support. It didn't prove to be very useful and at times caused issues.

Optimized source and made it easier to follow. There is almost zero latency when switching MP3 tracks now. This is the result of hardcoding the sampling frequency to 44100Hz and thereby not using the libmad library for a lot of overhead calculations. Also, file and ID3 tag data are parsed when the application is started.

Corrected a lot of bugs in id3.c. Files with multiple versions of ID3 tags were being parsed incorrectly as having v1.x tags.

Added support for ID3 JPEG cover art. Graphics.h was modified so that the LoadJpeg function would also take a "file offset" as an arguement. This allows for cover art to be easily read with jpeg_stdio_src.

There is no longer a "covers" folder. Cover art is only displayed if present in the ID3 tag, in JPEG format, and with the dimensions height<=170 and width <=170.

Song sorting is now possible by using the RIGHT TRIGGER. The sorting metods are: Title, Genre, Album, Artist, and Year.

Filenames are no longer displayed in the browser pane. The song's title is now displayed instead.

Layout was modified somewhat. Sampling frequency and bitrate are no longer displayed as the result of dropping the libmad overhead as listed above.

Various other bugs were corrected as found.

Controls:
A = Analog nub
D = Digital D-Pad

RTRIGGER - Toggle sort method.
DUP - Move up one track in browser.
DDOWN - Move down one track in browser.
DLEFT - Move up five tracks in browser.
DRIGHT - Move down five tracks in browser.
AUP - Increase volume.
ADOWN - Decrease volume.
ALEFT - Previous track. In random mode next random.
ARIGHT - Next track. In random mode next random.
SELECT - Toggle play mode.
CROSS - Play highlighted track.
SQUARE - Pause current playing track.

good work. and ive learned a lot from your source since ive been getting into c code lately, so thank you for that too.

i would like to suggest that you should try intrafont for your text. it'll look nice. thats if you would like to implement it.


EDIT: also i noticed some bugs in the displaying album art feature. it sometimes blitted off screen or randomnly all over the screen in a repeating pattern and flashing.

use psplinkusb to debug, and test etc, also use its scrshot command for taking screen shots ;). And if you'd like you could use RemoteJoy to do a video capture ;).

Hey thanks a lot for the feedback. I tried the intrafont lib at one point and had a lot of problems with it and the media engine. I never could figure out what was wrong so I gave up the idea ;) But it may be worth the revisit at some point.

Do you only notice the bug on certain songs? When coding and testing the batch of mp3s I have, I pretty much set all the fields and inserted the cover art into their tags manually using Audioshell for Windows. I'm guessing something in the code isn't detecting properly the lack of cover art or its dimensions exceeding 170x170, etc. All the mp3s I'm using have their ID3 tags reported as 2.3.

If you are willing, can you tell me the version of the tag being reported, the cover's type (JPG / PNG), and its dimensions in an mp3 that causes the bug?

Thanks

sure let me get my psp.... ok the id3 version is 2.3 from what your app says and i think some are jpegs and some are pngs but i don't remember which mp3s had which and i don't know how to find out. i think some of there dimensions are 240*240. i used mediamonkey to autotag them if your curious.

Thanks. I'll have to make some changes and not assume that the covers are jpegs. Once I figure out how to resize jpegs/pngs using the libraries that should solve the whole size issue. I posted a small 1.03 fix in original posting. But if you have some songs with 240x240 it probably won't help.

Thanks for getting back =)

no problem, glad to be of help. =)
