I had successfully moved VLC0.72 on Xscale(pxa255).The plateform is Montavista
linux for xscale.VLC can decode the MPEG4 video and display it.But the video
quality is not good .The ffmpeg drop frames horriablly.The display skip frames
serverly.The information printed on console is :
-------------------------------------------------------------------
[00000166] ffmpeg decoder error: more than 5 seconds of late video -> dropping
[00000166] ffmpeg decoder error: more than 5 seconds of late video -> dropping
[00000166] ffmpeg decoder error: more than 5 seconds of late video -> dropping
[00000166] ffmpeg decoder error: more than 5 seconds of late video -> dropping
............
-------------------------------------------------------------------
The configure option of ffmpeg is :--prefix=/.../target/usr --enable-static
--enable-shared --disable-debug --disable-altivec --disable-ffserver
--disable-ffplay --host=xscale --disable-faac --disable-a52 --enable-pp
--enable-amr_nb-fixed --tune=strongarm1100 --disable-mmx --cpu=arm41
--cross-prefix=/.../bin/xscale_le- --disable-mp3lame --disable-faad --disable-sdl
How the perfermance your vlc on xscale is?
How can i modified it to let it work with mpeg4 video smooth on 352*288 25fps on
xscale?
