[vlc] Re: CANNOT play avi and asf with opie-vlc in iPAQ

[Andrew leung]

Dear Jean - Paul Saman,


***************************************************

Thank you very much, with opie-vlc 0.5.1, the video is much better than before, now it is working!!! (But may have to try a few times to get one attempt resulted in a good working)

I would like to express my appreciation for your help so far again.

***************************************************

Now its is much stable, I keep using 160X128, ffmpeg still calims its bitrate is 32k for video (which is the bitrate claimed so far)

I will try other setting anyway.

Is the previous unstable performance all caused by vlc-0.4.6's problem but now the bitrate? From its performance now, shall we said that our previous conclusion on the quality and bitrate be changed?


Anyway, would you knidly tell me like the difference between 0.4.6 and 0.5.1?

1)why 0.5.1 has explicitly installed ffmpeg.ipkg? (seems that 0.4.6 does not have a seperate package installation for ffmpeg.
2)If I use MPEG-1 / 2, is this ffmpeg.ipk not used? (because you have mentioned that ffmpeg is for MPEG4 or DIVX
3)Overall speaking, what has been upgraded in 0.5.1?
4) it also install opie-netsetup from the feed itself, again what is the use of opie-netsetup?


Although opie-vlc is only a command line mode stuff, I am happy enough to have a working package now, I have tried to write GUI for iPAQ before but was facing a very very high diffficulities, the cross complier, tmake, qt - embedded made me crazy!!!


Thank you for your great job (and your colleages') in making opie-vlc.


Thanks,
Andrew
