stream to Twitch - framerate is missing in global header

[STL1811]

Expected behaviour

When streaming RTMP stream to Twitch, RTMP Header with duration, width, height, videocodecid, audiodatarate, audiosamplerate, audiosamplesize, stereo, audiocodecid, encoder, filesize AND FRAMERATE seems to be better decoded than without framerate.

Current behaviour

with CasparCG v2.3.3, global header is filled except framerate.
with CasparCG V2.0.7 or ffmpeg, global header contains framerate also.
