| 12 // TODO(hbos): This is essentially a copy of an encoder class in WebRTC that as |
| 13 // of this statement has not yet landed, but that I want to have accessible in |
| 14 // Chromium before that CL lands. This is because I use it in order to validate |
| 15 // the build files for OpenH264 and the WebRTC encoder/decoder CL cannot land |
| 16 // until I can build OpenH264 from source. Once the build files are stable I |
| 17 // will land both CLs and remove this copy of the encoder. |
