[SOLVED] cross compil arm support mp4v

[X-h]

I finally manage to build vlc for arm by removing a lot of options (cf viewtopic.php?f=13&t=36930&hilit=):

Code: Select all

--disable-mad \ --disable-ffmpeg \ --disable-a52 \ --disable-libmpeg2 \ --disable-hal \ --disable-dbus \ --disable-dvdnav \ --disable-libcddb \ --disable-x11 \ --disable-glx \ --disable-xvideo \ --disable-xinerama \ --disable-opengl \ --disable-screen \ --disable-bonjour \ --disable-qt4 \ --disable-skins2 \ --disable-taglib \ --disable-freetype \ --disable-lua

I would like to play mp4 file (? codec are not my speciality as well as cross compilation )

main decoder error eror: no suitable decoder module for fourcc 'mp4v'

What option/library should i use ? (plz don't tell me ffmpeg as I can manage to compil it )

As far as i understand mp4v support is done by x264:
I build it with the following option:

Code: Select all

./configure --host=arm-none-linux-gnueabi

and try to build vlc as follow:

Code: Select all

./configure --host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi -prefix=/home/xavier/arm-linux \ --disable-mad \ --disable-a52 \ --disable-libmpeg2 \ --disable-hal \ --disable-dbus \ --disable-dvdnav \ --disable-libcddb \ --disable-x11 \ --disable-glx \ --disable-xvideo \ --disable-xinerama \ --disable-opengl \ --disable-screen \ --disable-bonjour \ --disable-qt4 \ --disable-skins2 \ --disable-taglib \ --disable-freetype \ --disable-lua \ --disable-ffmpeg \ --enable-x264 --with-x264-tree=../x264

I know have the following error during the configure

Code: Select all

checking for x264.h in /home/xavier/arm-linux/x264... yes checking for x264_encoder_open in -lx264... no configure: error: the specified tree hasn't been compiled

(I am still trying to build without ffmpeg, should I?)
Any help would be appreciate.

BTW, if anybody can explain me the difference between host and target, I mean, i every example of cross-compiling I have seen, the host was the same as the target ... so what is the point ? (I am sure there is one )

I'm afraid you understand badly.

x264 is an h264 encoder.

Mpeg4 video is decoded by ffmpeg.

The target option is only usefull if you compile compilers. it's of no use for vlc or ffmpeg

I'm afraid you understand badly.

unfortunately right

x264 is an h264 encoder.

Mpeg4 video is decoded by ffmpeg.

Ok

The target option is only usefull if you compile compilers. it's of no use for vlc or ffmpeg

Make sense then.
Thank you very much for this quick answer

Hello,
have u finally managed to compile vlc with ffmpeg? If not, how did u managed to play mp4v?
I'm sorry if these questions look stupid, but it's almost one full day I'm trying to cross-compile vlc for arm and configure doesn't succeed unless I disable ffmpeg... ;(

Any hints?

Thanks,
Giorgio

It's been a while but I think I managed to compile ffmpeg. I gave up in the end as the performance was not good enough
Sorry that I can't help you more ...

[guappo]

I've passed thru a cross-compilation of MPlayer and linked to ffmpeg with success (in late evening). Unfortunaly I confirm very poor performances on my PXA270...
Thanks for your prompt response X-h. Good luck
