[FFmpeg-user] 'Delay between the first packet and last packet' errors?

[christina zou]

Hi,

I am streaming audio/video to Youtube with ffmpeg. After about 45 seconds,
I start to get this error every second:

*[flv @ 0x18b3cd0] Delay between the first packet and last packet in the
muxing queue is 10100000 > 10000000: forcing output*

Simultaneously, the bitrate reported drops, and Youtube reports that the
data being received is low quality (although the fps always stays at the
same target of 10 fps).

What does this mean? Any suggestions?
