Where is the source code of OMX CORE and libstagfrighthw in imx8m Android 13.0.0

[xiayanfire]

I only find openmax_il in imx8m Android 13.0.0_1.0.0 (L5.15.71_2.2.0 BSP).

But the functions defined in OMX_Core.h are not implemented inside.

  Where is the source code of OMX CORE and libstagfrighthw ?

Hi @xiayanfire,

I hope you are doing well.

OpenMAX Integration Layer (IL) - The OpenMAX IL provides a standardized way for Stagefright to recognize and use custom hardware-based multimedia codecs called components. You must provide an OpenMAX plugin in the form of a shared library named libstagefrighthw.so. This plugin links Stagefright with your custom codec components, which must be implemented according to the OpenMAX IL component standard

i.MX OMX Codecs
Binary: device/fsl-codec/lib/
Source: external/fsl_imx_omx/

Thanks for reply.

I got the Android 13.0.0 source code as the README showed below:

imx-manifest/README at imx-android-13 · nxp-imx/imx-manifest · GitHub

And imx-android-13.0.0_1.0.0.tar.gz is download from the link:

https://cache.nxp.com/secured/bsps/imx-android-13.0.0_1.2.0.tar.gz?__gda__=1683292693_4b7e616985796a...

But I did not find the pathes:

Binary: device/fsl-codec/lib/       Source: external/fsl_imx_omx/

Did I got the code wrong, or does the Android 13 code no longer contain this part of code.

Thanks & Regards,

Thanks for your reply.

But the codes in the fold hardware/qcom/  are copyrighted by QUALCOMM Inc not NXP.

These codes can not call into the NXP vdec driver.

Hi @xiayanfire,

I hope you are doing well.

I hope you have found the source code, if the issue is solved, can I close the thread?

I'm afraid it didn't solve my problem

Because the codes in the fold hardware/qcom/  are copyrighted by QUALCOMM Inc not by NXP.

These codes can not call into the NXP vdec driver.I need code that can interface to the NXP vdec driver

Hi @xiayanfire,

I hope you are doing well.

we haven't used openmax_il in Android 13

From android10, google has introduced codec 2 api to replace openmax il for vpu decoder/encoder component, we have implement codec2 decoder/encoder component and its location is android13/vendor/nxp/imx_android_mm/codec2

Thank you very much for your patient and professional reply, which cleared up my doubts, and according to you I have found the code of nxp's omx core in the code repository of AN 9.

Thanks for your reply.

I have found the ppt you mentioned in the forum before.But I did not find those two pathes in my code:

Binary: device/fsl-codec/lib/
Source: external/fsl_imx_omx/

Maybe the path is different on Android 13?

I got the Android 13 code as the README saied:

imx-manifest/README at imx-android-13 · nxp-imx/imx-manifest · GitHub

$: tar xvf imx-android-13.0.0_1.0.0.tar.gz

$: source ./imx-android-13.0.0_1.0.0/imx_android_setup.sh
