webrtc/test/testsupport/frame_writer.cc
kjellander@webrtc.org 173b7bbc16 Integration test that tracks dropped frames and compares video output.
The recorded frame timestamps are used to modify the output video on a frame-per-frame so it can be compared with the reference video using PSNR. This code will make it possible to use vie_auto_test for full stack comparisons with network interference and similar interesting simulations.

There's some refactoring done in vie_comparison_test.cc to make it fit to the new test.

Compiled and executed in Debug+Release on Linux, Mac and Windows.

TEST=vie_auto_test --automated --gtest_filter=ViEVideoVerificationTest.*
