Hello Daiane, Ok, even if the mp3 is not VPU accelerated (sorry for my stupid thinking) i want to insert in the OS all the multimedia support to be ready in the future, if will be necessary for other application.
Now, I have cloned the linux kernel sources and I usually work on my copy of it. When I'm ready, I generate a patch (with diff command) and insert it in my kernel recipe. Do you know how I can check my base version of the kernel? It is possible that my base kernel sources are old, but I don't know how to update them.. mmmmm... I'm not very familiar with yocto... Maybe you can help me?

I'm going to help you to get gst-fsl-plugin installed on your rootfs, although, I must say you that the mp3 encoder and mp3 decoder provided by gst-fsl-plugin are not accelerated by VPU (VPU is video only). It does have some hardware improvments, but it's only code optimization based on ARM instructions. > The preferred provider for my MACHINE is "linux" as you can see below > (I post my MACHINE .conf file FYR) > > > /*==================================================================== > ====== > ======== > #@TYPE: Machine > #@NAME: i.MX53 Quick Start Board > #@DESCRIPTION: Machine configuration for Freescale i.MX53 Quick Start > Board > > include conf/machine/include/imx-base.inc include > conf/machine/include/tune-cortexa8.inc > > SOC_FAMILY = "mx5:mx53" > > KERNEL_DEVICETREE = "${S}/arch/arm/boot/dts/imx53-qsb.dts" > > UBOOT_MACHINE = "mx53loco_config" > > MACHINE_FIRMWARE += "firmware-imx-ar3k \ > firmware-imx-ath6k" > > MACHINE_FEATURES += " wifi bluetooth" > > # > # Software/packages selection > # > PREFERRED_PROVIDER_virtual/kernel = "linux" If you're using virtual/kernel from meta-fsl-arm, please use: PREFERRED_PROVIDER_virtual/kernel = "linux-imx" instead. If "linux" point to your own kernel, please, make sure you have ported all IPU related code. > > # Extra udev rules > PREFERRED_VERSION_udev = "164" > PREFERRED_VERSION_udev-extraconf = "0.0" > MACHINE_EXTRA_RRECOMMENDS += "udev-extraconf" > /*========================================================================== > ======== > > > Including the package gst-fsl-plugins in my .bb file the error of my > previous email occurs. > Any suggestion?
