Changes regarding OMX_Broadcom in arm64 vs legacy rapsbian image #728

Closed rubu closed 2 years ago

rubu commented 2 years ago

Maybe this is not the best place to ask this, but I could not find any info, so any pointers would be appreciated (and the issue can be closed then).

What has happened with OMX_Broadcom.h and other vcos headers in the new (non legacy) Raspbian image? The headers are there in the legacy image, but my software which was using them, does not compile on the new image. Has the functionality been totally removed/deprecated? What is the proper way to use the OMX H.264 decoder and rendering APIs if those headers are gone?

openmax has been deprecated for a long time, and is not longer installed on RPiOS bullseye. openmax has never supported arm64 and never will.

It is recommended you move to v4l2 for video encode/decode.

You are free to remain on the legacy (arm32) buster image if these interfaces are important to you.

openmax can currently be used on (arm32) bullseye if you install the libs yourself. Cloning and building this repo should get you the libs and header files you need. But be aware these libraries will get no support and may stop working completely in the future.

Ok, thanks for the info - I'll stay on buster for now, and port to v4l2 when possible, thanks:)
