[vlc] MPEG streaming OK with opie-vlc and WLAN but not Bluetooth

[Andrew leung]

Dear Jean - Paul (and ALL),

Hello, Jean - Paul. After working for a few months and with your value advices so far, now  Iam quite sure to say it is really not ok to receive MPEG - 1 or other high - BW - required video streaming with bluetooth.


My testing result is, using WLAN 802.11b, D - Link WLAN card on both iPAQ(client) amd server(a simple linux PC), a MPEG - 1 video and audio UDP streaming has no problem , provided that the client is running opie-vlc and the server is running vlc.


keep whole set up unchange except replacing WLAN with a bluetooth PCMCIA card (Sunderland), NO movies anymore, opie-vlc gives many dropping buffer error and PTS out of range warnings


I think these results let us to conclude, quite sure, the bandwidth is the main factor.


I also have to raise that this bluetooth card is implemented with UART limition to gives max bitrate ~ 120kbps, not theoretical 700 kbps, this is the info from bluez mailing lists.

finally I have to add tha tthe movie I used for the test is a 352 X 240 MPEG-1 file.





Jean - Paul, would you mind kindly tell me again your testing's video 's info provided that THAT VIDEO is OK in opie-vlc? say, the resolution and encoding? :) 


Thank you very much,
Andrew
