[WebRTC][GStreamer] Fails to build without OpenH264 after r275275

• Component: WebRTC
• Status: RESOLVED DUPLICATE

[Carlos Alberto Lopez Perez]

In r275275 optional support for using OpenH264 was added.

However, this is failing build without it.
I tried to fix this on bug 224089 but there are more issues.

See the failure log from the bot:
