Linux/PROCESSOR-SDK-AM65X: GStreamer plugin compilation

Steven Chiu
Intellectual 335 points
Part Number: PROCESSOR-SDK-AM65X


Tool/software: Linux

hi,

I followed in the instruction at the bottom of this getting started guide. I seem to have successfully ran the make command. I just dont know what to do next in terms of what file goes where on my target file

system.

I am running linux on the AM65xx IDK eval board right now.

Can someone show me where to put the files generated from make on top the target file system?

    Hello,

    I am sorry for delay I was OoO. 

    You could follow this guide:

    http://software-dl.ti.com/processor-sdk-linux/esd/docs/05_03_00_07/linux/Overview_Building_the_SDK.html 

    For example if you want to build the gstreamer1.0-plugins-bad you could use:

    MACHINE=<machine> bitbake gstreamer1.0-plugins-bad

    After that you could copy the libs(.so files) under usr/lib/gstreamer-1.0

    Hope this helps.

    Best Regards,

    Margarita

    Hi Margarita,

    I figured out how to use bitbake to build the plugins, but I haven't figured out how to include x264 in the ugly plugin.

    I found this post but it didn't work for me.

    https://e2e.ti.com/support/processors/f/791/t/626163?Linux-AM5728-Gstreamer1-0-plugins-ugly

    Can you tell me how to include x264 in the build?

    Thank you,

    Steven

    Hello,

    The recipe for ugly plugin is available but by default the arago configuration prohibits the build of gst-ugly-plugins and some of its dependencies because of licensing limitations. Please, refer gstreamer1.0-plugins-ugly.inc and gstreamer1.0-plugins-ugly_$version.bb

    You could edit tisdk/sources/meta-arago/meta-arago-distro/conf/distro/arago.conf  

    LICENSE_FLAGS_WHITELIST = "commercial_gst-ffmpeg \
                                                            commercial_gst-plugins-ugly \
                                                            commercial_mpeg2dec \
                                                            commercial_lame \
                                                            commercial_x264"

    MACHINE=<Machine> bitbake gstreamer1.0-plugins-ugly

    You could find the ugly plugin here :

    tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/gstreamer1.0-plugins-ugly

    after compilation.

    Here is where you could find the libs:

    tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/gstreamer1.0-plugins-ugly/1.x.x-r0/image/usr/lib/gstreamer-1.0

    You must cp these libs (libgstx264.so) under /usr/lib/gstreamer-1.0 in rootfs.

    You know that the software codecs are running on ARM. 

    I would recommend you to check threads property. For example, threads property of  x264enc by default is 0.

    "threads : Number of threads used by the codec (0 for automatic)
    Unsigned Integer. Range: 0 - 2147483647 Default: 0"

    I would recommend you to try threads=2.

    ( ... ! x264enc tune=zerolatency pass=qual quantizer=27 subme=4 threads=2 bitrate=1024 key-int-max=4 ! ...)  

    With 

     gst-inspect-1.0 x264enc

    command you could check the other properties of the element. Or you could check them here:

    https://gstreamer.freedesktop.org/documentation/x264/index.html 

    Hope this helps.

    Best Regards,

    Margarita

    Hello,

    In additional, please check RELEASE file in gst-plugins-ugly about license.

    I ran "MACHINE=am65xx-evm bitbake gst-plugins-ugly" and was not able to find libgstx264.so anywhere in the build directory

    then i tried running "MACHINE=am65xx-evm bitbake gstreamer1.0-plugins-ugly"* and still wasnt able to find libgstx264.so

    *note i had to update the whitelist in arago.conf from "commercial_gstreamer1.0-plugins-ugly" to "commercial_gst-plugins-ugly".

    i went ahead and tried to graph the dependencies for gst/gstreamer1.0-plugins-ugly recipe and the recipe-depends.dot file didnt contain any references to x264.

    recipe-depends.docx

    *had to change the .dot file to .docx so it can be uploaded. change it back to .dot to view file.

    did i miss something with the whitelist setup?

    Thank you,

    Steven

    Hi Margarita,

    i got it to work. I had to add x264 to the PACKAGECONFIG in gstreamer1.0-plugins-ugly.inc

    Hello,

    Yes, you must add it in gstreamer1.0-plugins-ugly.inc also. 

    Please refer my above answer about the threads property of x264enc element. It could be in help. 

    Please if you have new questions open a new thread.

    Best Regards,

    Margarita
