Custom build fails to use the system h264 encoder

[hashworks]

I'm the maintainer of the Arch Linux OME package, which is build to use the system libraries (/usr/lib) and does not use the prerequisites.sh script.

It works fine with a bypass profile, but starting a stream that requires h264 encoding fails with E [Dech264:2251236] Transcoder | encoder_avc_openh264.cpp:131 | Could not find encoder: 27 (h264) (which references this line).

One could think that it can't find the libx264.so library, but ldd /usr/bin/OvenMediaEngine says otherwise:

[...]
	libx264.so.164 => /usr/lib/libx264.so.164 (0x00007f5997600000)
[...]

This is the config I'm using. Sending a stream 'foo' to the RTMP port successfully starts the foo OutputStream, but fails to create the foo_encode OutputStream with the aforementioned error.

Any ideas?

My bad: This error happens since for encoding with h264 OvenMediaEngine requires ffmpeg to be build with --enable-libopenh264, which isn't enabled in the Arch ffmpeg package.

Yes, due to license conflict (OvenMediaEngine:AGPLv3 / x264: GPLv2), OvenMediaEngine removed x264 a long time ago and are using OpenH264.
