RTCVideoEncoderFactory: Ignore invalid H264 profiles/levels

The RTCVideoEncoderFactory was crashing due to a dereference of
an std::optional<std::string> when encountering an unsupported
combination of H264 profile and level returned by the GPU
factory.

This commit addresses the issue by ignoring such unsupported
combinations, preventing the crash and ensuring more robust
handling of video encoding profiles.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
