(PIX_FMT_NV12) to MPEG4 without first converting the format to YUV420P?
Currently the conversion takes a too long to convert 1080p (~150ms per
frame) for me to stream at 30fps. I am attempting to stream the output to
VLC at 30fps but the frames are being dropped.

Do you have yasm disabled in your build?
