Title: Trying Rockbox
Post by: Vortex on May 05, 2007, 08:02:19 AM: Hi everyone,

I'm thinking about buying a Sandisk Sansa e280 mainly because it is an affordable small portable player with lots of (expandable) flash-memory.

Since I want to use Rockbox on my Sansa I decided to try it out a bit, before actually buying the player. I'm aware that support for the Sansa is still in it's early stages but nevertheless I wanted to try out some of the general features of Rockbox.

I checked out an svn-version of rockbox and then proceeded to compile and set up the UiSimulator, according to the instructions in the wiki.

The UiSimulator starts up fine, but every time I try to play a song the WPS-Screen is displayed for a split-second, then the UiSimulator segfaults.
This is what it prints out before crashing:
Code: [Select]
We open the real file 'archos/Music/Soilwork/Soilwork - Figure Number Five.mp3' ID3V2 Length: 0x5000 framelen = 13 id3v2 frame: COMM framelen = 19 id3v2 frame: TIT2 framelen = 5 id3v2 frame: TYER framelen = 7 id3v2 frame: TPUB framelen = 5 id3v2 frame: TCON framelen = 19 id3v2 frame: TALB framelen = 2 id3v2 frame: TRCK framelen = 39 id3v2 frame: PRIV framelen = 41 id3v2 frame: PRIV framelen = 31 id3v2 frame: PRIV framelen = 138 id3v2 frame: PRIV framelen = 9 id3v2 frame: TPE2 framelen = 34 id3v2 frame: PRIV framelen = 39 id3v2 frame: PRIV framelen = 20 id3v2 frame: PRIV framelen = 14 id3v2 frame: PRIV framelen = 17 id3v2 frame: PRIV framelen = 26 id3v2 frame: TCOM framelen = 9 id3v2 frame: TPE1 framelen = 19212 id3v2 frame: NCON framelen = 2 id3v2 frame: TLEN framelen = 0 Header: fffbb004, Ver 0, lay 3, bitr 192, freq 44100, chmode 0, mode_ext 0, emph 0, bytes: 626 time: 1280/49 Space between ID3V2 tag and first audio frame: 0x0 bytes First frame is at 5000 Segmentation fault
My System is:
Code: [Select]
$ uname -a Linux kellerkind 2.6.20-viper10 #1 PREEMPT Fri Apr 27 20:50:58 CEST 2007 x86_64 AMD Athlon(tm) 64 Processor 3500+ AuthenticAMD GNU/LinuxRunning 64bit Gentoo-Linux.

Is this a known issue with the Simulator?

Another thing I noticed while using the Simulator, was that the font used in the menus and in the file-browser was almost unreadably small (even on my computer's monitor). Is there a way to increase the font size in the menus (especially on the real Sansa)?

EDIT: Just tried playing a FLAC-File and it played nicely. However it crashed again upon finishing playback of the file. ???
I will try some other formats and files...

EDIT2: It plays OGG and FLAC files nicely but crashes on track change. It doesn't play mp3 files at all.

Post by: amiconn on May 05, 2007, 08:41:30 AM: This is a known issue with a rockbox specific optimisation in libmad which hits 64 bit simulators. Other formats than mpeg audio will work fine.

Post by: Vortex on May 05, 2007, 10:31:46 AM: Thanks for pointing that out. :)

However, I came across some more problems with Rockbox and would like to know, whether these also exist on the real Sansa.

Rockbox doesn't seem to be able to read tags from ogg files. Can Rockbox only read ID3 tags from mp3 files?

Only a few of the supplied fonts work, others crash the simulator. Is there a way to freely change the font size to something larger?

Indeed, but it still crashes on track change, even when the next file is not an mpeg file. It even crashes when I play only one file but set the playback mode to "repeat one".

Id3 tags are for mp3 files. Rockbox read regular ogg tags from ogg files. I don't think Rockbox accepts id3 for other formats, no.

The fonts are bitmapped so you need to pick the font you like. It sounds like you have found more (64bit?) simulatior-related bugs.

However, the tags of my ogg files are not recognized by Rockbox (at least in the emulator). It just displays the filename in the WPS screen. When I select "Show ID3 Info" from the context menu while playing, it says "no info" for every property.

Post by: safetydan on May 05, 2007, 07:34:34 PM: It sounds like there may be some issues with the tags in your ogg files. Try checking them with ogginfo and see if that shows the tags correctly. If you don't have or can't use ogginfo, try loading them up in another media player that supports oggs and see if the information is shown correctly.

Rockbox does fully support reading tags/metadata from ogg streams so there should be no issues. There are problems though if you've used bad software (grip is one example) that sticks and ID3v1 or ID3v2 tag on an Ogg file. That doesn't work.

Post by: safetydan on May 06, 2007, 07:00:07 AM: Try checking to see if there's an ID3 tag or something in the file. Quickest way is to open the file in a text editor and see if the file starts with the bytes ID3.
Title: Re: Trying Rockbox
Post by: Vortex on May 06, 2007, 09:12:22 AM: Nope, the file starts with "OggS" followed by garbage and then the tags in plain text.

It looks like this:

Post by: nls on May 06, 2007, 10:08:18 AM: The tag reading problem is known for 64bit sims, and has been reported here http://www.rockbox.org/tracker/task/6690
It works fine on the player though.

Edit: the tag reading should now work ok on your 64 bit sim with the latest svn.

It really does. ;D

However, I still cannot initialize the database. It says "Building database... 0 found (OFF to return)" and hangs.
I guess this is another problem that only happens on the sim, right?
