Hi @jyijyi ,
I remove gstreamer-good then the image size is 38MB, but I use gstreamer in shell I got WARNING and it cannot create file.
WARNING: erroneous pipeline: no element "v4l2src"
I want to follow your steps to install ffmpeg but I got error.
1. download the yocto source and go to ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc
2.add the following line:
IMAGE_INSTALL_append = " ffmpeg"
3.go to ./meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf
change UBI_ROOTFS_SIZE ?= “48MiB”
4. Make the yocto image and download to the module
My step
1. download ffmpeg_6.0.bb (https://git.yoctoproject.org/poky/plain/meta/recipes-multimedia/ffmpeg/ffmpeg_6.0.bb)
2. create ffmpeg folder in ./meta-openembedded/meta-multimedia/recipes-multimedia/
3. put ffmpeg_6.0.bb into ffmpge
4. modify ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc to add
IMAGE_INSTALL_append = " ffmpeg"
5. make
I got error
Build image of minimal rootfs (for swi-mdm9x28).
