Rockbox Bulletin:

Good News!
Slasheri is working on mp3 and ogg playback. He managed to play continiously mp3 and ogg files via the default GUI (folder view). Now he is working on optimizations, gapless and overall fix of the playback.

Bad News!
This patch is not comitted on CVS yet so we cant test it ourselves with a single daily build.

Next will be file playback including While-Playing-Screen (WPS)!!!!!

Visit IRC logs (day 27,28 May) to read it yourself.

P.S: I just hope that I read it right...

quoted today on irc

(16:19:24) (Slasheri) now doing a new test. there was some bugs present in the code
(16:28:44) (rasher) Slasheri: how did it go?
(16:29:00) (Slasheri) rasher: still one minor bug delaying the test
(16:29:05) (rasher) ah
(16:39:3 (Slasheri) minor bug found, problem was that in code there was =- and should be -=
(16:39:47) (preglow) ahhaha, nice
(16:39:51) (ashridah) rofl.
(16:39:52) (Slasheri) indeed
(16:41:49) (Slasheri) ashridah: aah, now it was 100% gapless switch =)
(16:41:57) (Slasheri) preglow, sorry
(16:41:57) (preglow) the test tone as well?
(16:42:00) (Slasheri) yes
(16:42:01) (Slasheri) very well
(16:42:03) (preglow) excellent
(16:42:05) (preglow) then you're good to go
(16:42:07) (Slasheri)
(16:45:11) (preglow) and you do gapless by just shaving the last frame of a song a bit?
(16:47:09) (Slasheri) with ogg files no raw pcm data is shaved out
(16:47:22) (Slasheri) but with mp3s that will be necessary
(16:48:20) (Slasheri) i already have some ideas how to do that with mp3's
Shagnar: (16:48:57) (preglow) ahh, then tremor does it for you
(16:49:04) (Slasheri) yep
(16:49:14) (preglow) how long until we'll see a patch again? :P
(16:49:44) (Slasheri) maybe a few more days. It would be too soon to release it today because there is still lot to do
(16:52:32) (Slasheri) now i could do some filebuffer optimizations so the same codecs will not be loaded to file buffer between every song. Only when codec changes, that loading would be necessary
(16:53:45) (Slasheri) currently the rockbox will also fully load the ram buffer, no matter even if it's necessary to cut the last song
(16:53:4 (preglow) codecs should be loaded when you load files into the file buffer
(16:53:5 (Slasheri) yes, i will do it to work that way
(16:54:0 (preglow) we'll need to branch out the iram copy in some way
(16:54:23) (preglow) so we can switch codecs without having to load them from disk
(16:55:41) (Slasheri) in my current implementation, all necessary codecs are loaded into filebuffer and when it's necessary to use a codec, it will be loaded to iram from that filebuffer instantly
(16:56:12) (Slasheri) the switch is gapless because there is audiobuffer also
(16:56:30) (Slasheri) and that won't limit how many different codecs can be in the buffer at a time
(16:58:22) (preglow) holy shit, vorbis is good at lower bitrates
(16:58:25) (preglow) it beats aac to a pulp
(16:58:44) (Slasheri) 7
Shagnar: und s beste:
Shagnar: (16:59:23) (preglow) i've encoded an album with avg bitrate 33kbps, and it sounds wonderful
(16:59:35) (preglow) i can hear it's encoded, sure, but quality is surprisingly good
(16:59:55) (ashridah) preglow: yeah, it does better quality at lower rates
(17:00:14) (ashridah) not quite as good as speex, depending on the job, but good for low-rate streaming
(17:00:15) (rasher) speaking of aac...
(17:00:20) (ashridah) (of music)
(17:00:33) (preglow) of course, but speex only does voice
(17:01:13) (ashridah) yes

Question regarding this patch/test: Is this the "Multi-codec Architecture" that will be in the final build of Rockbox, or is this a "Quick(TM) Hack" in order to allow playback NOW while we wait for the full Multi-codec Architecture?

EDIT

Just went over to The IRC Channel - It appears this is the Multi-Codec Architecture after all!

[14:22] <FingerSoup> I've got a question regarding Slasheri's recent work on playback.... Is this the "Multi-Codec Architecture" he's implementing, or is this a "Quick(TM) Hack" to enable playback while we wait?
...
[14:23] <HCl> FingerSoup: first
[14:24] <FingerSoup> W00T! good news! Thanks!
[14:26] <HCl> incidentally, can we play wavs with it?
[14:26] <preglow> no
...
[14:26] <preglow> but a wav codec should be quick to whip up
[14:26] <HCl> should be easy to add, no?
[14:26] <HCl> *nods*
[14:26] <HCl> thats something to do when its in cvs
[14:27] <HCl> flac was realtime too, right?
[14:27] <preglow> yes
[14:27] <preglow> wavpack too
[14:27] <HCl> nice, nice.
[14:27] <HCl> we really need linus :/
[14:27] <preglow> he'll come on some time tonight with a bit of luck
[14:27] <HCl>

Rockbox Booletin!

The long awaited Slasheri's Playback Parch has been finally commited!

Downlaod the latest version or Rockbox and a "playback" surprise is waiting you. Gapless playback with OGG and MP3 is true.

Though watch it! All these nice add-ons are still very experimental and unstable. A lot of crashes will occure if you play around. Dont't whine all will be solved by time.

Remember that the reset button is your friend and not an enemy. Press it when the system crashes and all pain will be cured!

P.S: Last but not least, an updated snake game has come for us iriver users, by HCl.

[Tang]

Just a precision to what XavierGr said:
For now with the daily build only Ogg Vorbis is really GAPLESS... Lame mp3 (3.96.1 for me) still add a very short but "hearable" gap...

preglow if it works, then hell yes
linuxstb I think it's working (I'm listening to a track now). I'll commit it.

Current bleeding edge now has crossfade and lots of other improvements.

[dapureplaya_04]

The LCD remote is coming along very well.

Just testing it out now. At the moment it displays the rockbox logo on the screen. Not much works when navigating through the folders (except shutting rockbox down), but when it's in the "now playing" screen, the stop button , next/prev track (not incl. song scanning), volume up/down and the hold button is functioning well.

[dapureplaya_04]

WAV playback implemented - only 16-bit Stereo 44.1KHz files supported!

Haven't tested it out myself but will do so later....

[dapureplaya_04]

AC3 and Wavpack playback has been implemented.

Wavpack works very well and i noticed that it doesn't work the hard drive as much as some of the other codecs.

So far the following has playback:-
-MP3
-OGG
-FLAC
-WAV
-WAVPACK
-AC3

That's more than what iRiver FW supports!

[stevenz]

Recording implemented in latest daily build for H1xx (20050619):

Iriver: First attempt at recording. Use Info->Debug->PCM recording to test recording of wav-files. Seams to work fine except occasional 100 ms noise at pos 100 ms (not later) so initialization or synch problem..

Several small H300 control-related additions as well, fair way from usability judging by the number of compiler warnings/errors. Looks like Daniel is doing most of the H300 work, good man!

[Tang]

20 Jun 12:24 Thom apps/plugins/codecmpc.c 1.2 Musepack files should play (poorly) now.

Take it as a start...

[stevenz]

Latest builds are starting to use the massively reworked graphics code which should speed things up significantly. There are a few "Oopses" resulting from the 06-25 daily build as a result judging from corrections since, doesn't look like anything too major.

Hopefully will lead to grayscale support?

I notice there's now USB-charging support for the Ondio and some of the other units, no specific mention of iRiver support though.

Can't be done on the iRiver H1xx's. Hardware limitation . . .

[dobz]

Wooohaa

Just tried todays build and it plays MP3 (Lame 3.96 preset standard with id3v2.3 tags) (Tiesto - In search of sunrise 4) 100% gapless

nice thing about this album is that the mix happens before the end of the track change, so the gap/no gap is obvious to spot

Previous builds played with a very small gap

but no longer \o/ 3 cheers

[XavierGr]

Amiconn will try to implement grayscale support this week!

For the remote lovers:
I made a quick hack to be able to use the remote on filetree and wps.
It has some display bugs but the most annoying is when browsing files that you cant see all items.(Look both at main and remote to see what is happenng) Also a slight misalignment of the timer occurs in the wps.

There is no commit for that. It is just a personal temporary hack until the UI implementation is fully done for the remote. I compiled using the latest build (29 of june).

To select a folder press the jog dial down. To move push left/right. The play button will resume.
Currently no icons, statusbar or scrollbar.

Use it at your own risk. Upgrade as usual.

You shouldnt have any problems 2 persons have tested this so far with no problems.

Bad news though for those that have the ticking problem. The ticks can be heard (with good phones at low volume) also in rockbox when scrolling of text occurs.

Find the build here!

[belgarath_the_sorceror]

11.20.43 # <amiconn> I'm almost done with the playergfx conversion, 4-grey comes next

Greyscale support coming soon!

[PorkRind]

Move to next directory after current finishes playing added.

Find it in the latest bleeding edge build

(Thanks, Hardeep!)
