Need help in MP3 Decoding with FFMPEG and cross compilation for AM335x for Audio

forwarding this to the SW team.

Hi Viswanath,

I advise to execute those steps from ti-sdk folder.

Set "arch=arm", "prefix" should be the folder where you keep the Arago fs binaries and "cross-prefix" should be arm-linux-gnueabihf- .
Also don't forget to export the PATH variable to point to your ti-sdk/linux-devkit/sysroot/i686-arago-linux/usr/bin.

It will also be useful to source the environment-setup file.

Best Regards,
Yordan

Thank you Yordan.

Thank you it is compiled and we are able to configure and make is also done with out error.

Command:
./configure --enable-cross-compile --cross-prefix=arm-linux-gnueabihf- --arch=arm --target-os=arm-linux --prefix=/home/vk29835/ti-sdk-am335x-evm-08.00.00.00/filesystem/tisdk-rootfs-image-am335x-evm/usr --enable-gpl --enable-nonfree --extra-cflags="-I/home/vk29835/ti-sdk-am335x-evm-08.00.00.00/filesystem/tisdk-rootfs-image-am335x-evm/usr/include" --extra-ldflags="-L/home/vk29835/ti-sdk-am335x-evm-08.00.00.00/filesystem/tisdk-rootfs-image-am335x-evm/usr/lib" --extra-libs=-ldl

here my doubt is: make : is it take as per configuration ..?? and

make install : where it will install -- or do we need to give any another path with cross toolchain for the target. ???  or else.

                             

regards,

Viswanath K

Hi,

Make install should put the output files (from the compilation) inside the specified --prefix path, in your case /ti-sdk-am335x-evm-08.00.00.00/filesystem/tisdk-rootfs-image-am335x-evm/usr

You can either use make install, or manually copy each of the compiled files to your filesystem.

Best Regards,
Yordan

Thank you Yordan. I cross compiled ffmpeg successfully. But no Luck. ffplay is not generated and with ffmpeg we not able to play the mp3 file.
and then we tried with gstreamer: gst-launch commands --- but still no luck
