compile rtpengine failed on ubuntu 22.04 with error "undefined reference to `av_channel_layout_default'" about rtpengine HOT 4 CLOSED

Do you want to build with or without transcoding support?

from rtpengine.

Hi rfychs !
First ,I want to build without transcoding !
I also want to know how to build with transcoding!
Thanks !!

from rtpengine.

The .deb build system doesn't support non-transcoding builds, so just changing the makefile and then trying to create a build won't work. Also you need to apply the backports from pkg/deb/ appropriate for your distro.

Not a problem with the code, closing.

Hi Hi rfychs !
I checked that backports do support Ubuntu 22.04;
then in the rtpengine/daemon directory, I modified the Makefile file with the statement: with_transcoding ?= no, and then running make, it can compile the rtpengine binary;
In the rtpengine/kernel-module, running make also generates the xt_RTPENGINE.ko file;

I now want to compile with the transcoding module, I have already installed the g729 deb package, and the ffmpeg deb package is also the latest, but it still reports errors.
