I have discovered the same cuts and using mplayer using a2dp without any other frontend (reniced to -19). While trying to figure out the reason of the cuts I have these thougt's: The cuts come when I drive the car in sunny weather (hot) after a while. The cuts come when I charge the bettery (car/wall charger). The cuts goes away after a while holding the phone into the air con stream. It seems a temperature problem. So first I thought the SD card or the path from there is a problem. But that isn't as I have tested mplayer in ssh to see console output. No error messages. Also I got no bandwidth problems downloading planet.bin for navit while playing music. Now I have tried to renice some other processes while testing it with the omnewrotate while rotating. There are also these cuts and after renicing kmmcd to -19 these cuts dissapeared. But I ran navit while these tests and when calculating a route the cuts appeared. But this may also solved by playing with the other related processes. But what I think is a problem when a phone call comes into the phone while all this. If mplayer' is running the ring event or the like should pause any mp3 or ogg players :-) It's because I have figured out much response problems while this happens and a phone call may get unanswered. Beside of renicing kmmcd, SDIO Helper and mplayer I then got a problem with my WLAN connection. So it is a bit more work to get all working well. I'll now test navigarion in a car, but it is not that hot today.

Re: intone a2dp (bluetooth) support
Hi, I've just got back from a trip - hence the delay. Intone is in the process of a minor re-write. I'm looking at improving the music manager, writing a small desktop sync client to manage music and tags and use ecore routines to handle mplayer. I still can't seem to get much clarity on A2DP usage. I don't think intone should really go around pairing bluetooth headsets behind FSO's back. I think that the pairing should be handled by FSO/some other utility/manually - if need be. Assuming that the pairing has been set up - I am looking at restarting mplayer with the flags to get it to stream over bluetooth. I'll add that as an option. Any other ideas/suggestions are welcome. Also, is there a way to get mplayer to stream mp3 data directly over BT - like gstreamer does? Or would it be better if I used gstreamer to send mp3 data over BT from intone - leaving mplayer paused? -- View this message in context: http://n2.nabble.com/intone-a2dp-%28bluetooth%29-support-tp3038819p3071056.html Sent from the Openmoko Community mailing list archive at Nabble.com. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: intone a2dp (bluetooth) support
Just another data point - if your using streaming audio across wifi (I am using mplayer streaming from my ISP's radio offerings), a2dp can suffer badly if using wmiconfig -i eth0 --power maxperf - it seriously interferes with bluetooth BillK On Wed, 2009-06-10 at 15:55 +0100, Michael Sheldon wrote: Yorick Moko wrote: One thing I don't understand: intone with a2dp: mplayer usage around 40% and sometimes spikes to everything available (80-85%) == no fluent playback intone without a2dp: 12% cpu == fluent playback how come? Well the a2dp stuff seems to be fairly cpu intensive, presumably because it's having to performing sbc encoding before sending the audio to the device (most devices support direct streaming of mp3 data but I don't think this is possible with mplayer, it is with gstreamer though). You should still be able to get reasonable mp3 playback, you won't get acceptable ogg playback though, as the combination of a2dp and ogg decoding appears to be too much for the cpu to handle. If you're getting very choppy playback with mp3s and you're using bluez4 then try running hciconfig hci0 lm master; hciconfig hci0 lp hold,sniff,park after starting the bluetooth daemon.

Re: intone a2dp (bluetooth) support
Hi to all, Sorry if this is out of topic. I want to ask those of you who already use a2dp, how is the sound quality? I tried to use my Neo as media player wit wired headsets, but it was almost a disaster, intone is great but the sound quality is bad. Not only the lack of bass … I was looking for solution but still can’t find something suitable. I was wondering if Bluetooth headsets offer better quality.

I agree but as I hadn't the time to update BlueMoko to bluez4 and FSO, that was a suggestion to achieve A2DP output after pairing with other means (if FSO does the pairing with headset profiles you should have only to create the .asoundrc file waiting for a GUI ;) ) Also, IIRC, BlueMoko still uses bluez 3.3, while most images now use bluez 4 by default. So if you went down that path you'd probably end up having to support two different methods of pairing. A2DP is easier to use (didn't see bluez4 yet) than headset, because you just need to pair and configure the default main alsa device as the headset, while headset profiles need routing and configuring the secondary alsa device and I didn't find yet a clean way to do this, but as I mentioned I hadn't the time to look at bluez4 and newer kernels so maybe the situation became better in the meantime (I hope :P ) Bye! ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
