Re: [maemo-developers] Sardine is back

If you were following the disto before the restarting it might be that an upgrade will work for you but given that the same component versions were rebuilt differently, a clean upgrade path might not exist. So resetting rootstrasps / reflashing might be necessary to get Sardine to work. I just tried it on OS2006 with the latest SW update and it worked fine for me. I still have to document the detailed steps, but basically I followed Frantisek's approach here: http://maemo.org/maemowiki/HowTo_GetStartedWithSardine There's also this page (google found it): http://sardine.garage.maemo.org/getting_started.html It would be less confusing if they were combined, with one redirecting to the other.

RE: [maemo-developers] Unresolved issues (Week 46)
If you want something free, I'd suggest using our speex codec, which is technically comparable, completely open, and has no known patent issues. We don't have an omap dsp implementation, but it has been ported to the various TI DSPs. http://speex.org/ -r I did quite a bit of experimentation with the 770 dsp back in late august. As a point of clarification, the dsp in the OMAP 1710 (used in the 770) is just a TI *C55x, *which is already supported by speex as far as I can tell.Thus, getting speex to work on the 770 should mostly be an issue of adapting the he exisiting speex C55x port to the build process using the free dsp tools, or TI's code composer; and writing appropriate wrappers to move data back and forth across the ARM to DSP boundary using the linux dsp gateway interfaces. There's still the problem of getting the DSP to output sound directly though, is there not? Or did you work out what the functions in the avs_kernel do (or bypass them completely)?

Re: [maemo-developers] WMA streaming
On Monday 13 November 2006 22:08, Andrew Barr wrote: What are my options for Windows Media Audio streams on the 770? Most Internet radio streams (I mean simulcasts of real broadcasts in this sense) are offered in (at least) this format, which is supported by free software (ffmpeg) up to version 2, the latest version I've ever seen anywhere. However, no one seems to have had any luck with third-party codecs on this device, much less for streaming. Is this device powerful enough to handle decoding audio streams using C or ARM-assembly codecs (from ffmpeg)? It's likely that the bitstream would be 16 to 24 kbps. I understand free tools for the DSP aren't quite there yet, so that may not be an option. FFmpeg library contains WMA decoder and MPlayer supports it at least on x86 desktop PC. There are some problems with its support on ARM though. First and the most easy to fix is that WMA decoder seems to have some alignment problems, so it crashes on any attempt to play WMA files. This is quite easy to workaround by running 'echo 3 /proc/cpu/alignment' as root, see https://maemo.org/maemowiki/PortingFromX86ToARM and the links at it for more information. A major problem with WMA decoder is that it uses floating point math. And having no FPU in hardware, Nokia 770 does not seem to be able to decode 128kbps WMA files to play them in realtime (sound is skippy). So it is not very useful unless somebody finds (or implements) a fixed point WMA decoder. However I also tested 20kbps WMA sample and it worked fine with CPU load at about 60%. So if anybody would like to have such low bitrate WMA files/streams supported, I can have a look at these alignment problems, fix them and release updated version of MPlayer for everyone to use. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 No, my dsp work was actually video related.I did reuse Siarhei Siamashka's mplayer code to decode/output mp3 directly, but that obviously doesn't help with speex. I'd suggest that the most practical approach for now would be to have an application that uses a speex dsp task to decode speex, and then takes the output from that speex task and routes it to an existing gstreamer plugin for pcm output. This may be suboptimal, as the data will cross the dsp gateway boundary twice more than necessary, but it still might retain most of the benefit of offloading speex work to the dsp.I mean were talking something like 64KB/s of extra copying in the worst case (?), which I don't think will be a very significant cost even on the 770's OMAP processor. The marginal benefit of persuing a zero copy solution (direct from dsp to sound) just probably isn't work the effort. Documentation for the software components of the 770 that use the dsp is virtually non-existent until now. Aside from the mp3 decoder, I think all of the other stuff has been basically unavailable to developers outside of those working on Nokia's closed source multimedia applications.

Just a disclaimer before anybody starts bashing my ugly hack that allows to use dspmp3sink for mp3 playback from mplayer :) I know that it is improper use of gstreamer api for audio synchronization, but anything that looked somewhat better (proper buffer timestamps, the use of gstreamer pipeline clock instead of system time, ...) appeared to work even worse in my tests. So the code that is currently used in mplayer is bad, but the other options seemed to be even worse :( Surely it was not the best experience to start getting familiar with gstreamer and I'm surely not going to start looking for the one who is at fault here, there is a high probability that I missed something important and it is me after all ;) Anybody who can fix gstreamer based output module for mplayer is welcome to submit a patch. The only excuse for keeping this bad code in maemo build of mplayer is that it provides some performance improvement and works quite acceptable (audio/video sync is ok) most of the time.
