Simon,

still the linphone hangs for me with the video enabled.

Thanks and Regards,

Simon,

When the video is disabled, this does not happen.

my ffmpeg configure option is,

./configure --prefix=$PREFIX --enable-shared --enable-cross-compile --cross-prefix=arm-none-linux-gnueabi- --arch=arm --enable-libvorbis --enable-libtheora --enable-gpl --enable-x11grab --enable-libopenjpeg --enable-libspeex --cpu=armv7-a

I think i need to add "mcpu=cortex-a8" and "neon" to compiler flags and try to recompile the ffmpeg and test whether this can make any difference.


Thanks and Regards,

Ater a google search, it seems this message comes from the linux kernel.
I don't know if it is a cause or a consequence of something else.
The mpeg4 decoding errors seems to indicate that video packets have been
dropped, probably because the processor doesn't succeed in decoding in
realtime.
Is your ffmpeg enough ARM-optimized to run on your processor ?
Does this problem happens also when video is disabled?
