Youtube FFMPEG webcam akışı kare düşer

Logitech HD Pro Webcam C920 kullanarak Youtube'da canlı bir video akışı yapmam gerekiyor. İşletim sistemim Fedora 20 ve kullanmaya çalıştığım komut şudur:

ffmpeg -f v4l2 -i /dev/video0 -flags +global_header -ac 1 -ar 44100 -ab 16k -s 640x360 -vcodec h264 -pix_fmt yuv420p -g 25 -vb 32k -profile:v baseline -r 30 -f flv "rtmp://a.rtmp.youtube.com/live2/NAME_OF_STREAM_REMOVED"

Akışı başlattığımda, çok fazla damla alıyorum ve Youtube hiçbir veri almadığını söylüyor. Sistemin iyi olup olmadığını görmek için bir video dosyasını yayınlamaya çalıştım ve çalıştı, bu yüzden hangi sorunu yaşadığımı bilmiyorum.

ffmpeg çıkışı :

$ ffmpeg -f v4l2 -i /dev/video0 -flags +global_header -ac 1 -ar 44100 -ab 16k -s 640x360 -vcodec h264 -pix_fmt yuv420p -g 25 -vb 32k -profile:v baseline -r 30 -f flv "rtmp://a.rtmp.youtube.comremoved-privacy-reasons"

Codec AVOption ab (set bitrate (in bits/s)) specified for output file #0 (rtmp://a.rtmp.youtube.comremoved-privacy-reasons) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.

Sorun şu ki, ses akışı için seçenekler belirledim, fakat aslında hiçbir yerde bir tane bulunmuyor
