Same here, remove '\' and add spaces around '/'.

Btw, shouldn't we track the audio bitrate too? Maybe something like:

 BWE_TEST_LOGGING_PLOT_WITH_SSRC(1, "MediaBitrate[bps]", now_ms,
    video_ ? VideoBitrateSent() / 1000 : AudioBitrateSent() / 1000,   
    packet->Ssrc());

Or update VideoBitrateSent to also include audio packets and rename it
MediaBitrateSent. We never use RtpSender for audio and video at the same time
anyway.
