Getting latest GStreamer & vpudec?

[VincasD]

Hi,

Some hardware manufacturer provided us toolchain named fsl-imx-wayland-glibc-x86_64-core-image-base-cortexa53-crypto-imx8mmevk-toolchain-5.10-hardknott for some imx8mm device, but it has rather old v1.18 GStreamer.

On the Desktop, we use latest 1.22.x with some relevant bug fixes, but these fixes "dissapear" if we build for IMX device with it's v1.18.

Alternative is to use gstreamer-imx decoder built for latest GStreamer manually, but it does not work nice with glupload, and I assume "official" vpudec is closed source and I could not rebuilt it for the latest GStreamer?

Or is there a way to get latest GStreamer & vpudec prebuilt for some older toolchains?

Thanks!

I finally managed to get stable 25fps without stuttering with gstreamer-imx using latest GStreamer 1.22.3, so I'm not searching for latest `vpudec`.

HI @VincasD 

Thank you for contacting NXP Support!

To obtain the latest packages in your toolchain you have to compile again the toolchain.

I recommend using the package versions installed on our BSP because we guarantee the functionality and version compatibility of all the packages installed on the BSP.

I am able to compile latest packages for my toolchain, but I can then only use gstreamer-imx, i.e. imxvpudec*, not "official" vpudec..?

Maybe there are vpudec binaries available for aarch64 somewhere built for GStreamer 1.22.x?

You should compile with kernel 6.1 that version includes version 1.20 and probably it is useful for you, that version is tested and guaranteed for imx products.

But this repository does not have "vpudec" GStreamer element, right? if I understand correctly. it's closed source software?

Hi @VincasD 

I think is possible to obtain the binaries but I can provide you only our packages included in our bsp.

Theoretically, if libc is not too old, and if I would match glib version against `vpudec` from some other aarch64 toolchain, it could work?

But does NXP support 1.22.x GStreamer at all? Are there toolchains with latest GStreamer?

Thanks!
