ffmpeg streaming to youtube slow
1er avril 2017, par boygiandiI’m trying to send a video file to youtube as livestreaming. The stream command look like this
ffmpeg -re -i "/tmp/4745.mkv" -acodec aac -pix_fmt yuv420p -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset fast -g 60 -r 30 -crf 1 -f flv "rtmp ://...."
The last line of output log look like this
[ sh : 2017-04-01 7:19:54 ]size= 242706kB time=00:21:08.11 bitrate=1567.9kbits/s speed=0.882x
As I understand, the speed=0.882x mean it send data to youtube slower than expected ( 1x mean streaming fine, lower mean buffering ). I tried to change some params of ffmpeg command, like change -preset fast to superfast, ultrafast : it faster but quality very bad and I still can’t control the out put speed. Sometime it’s 1x, sometime lower.
Note that I run more than 1 ffmpeg instants at the same time, it may problem of CPU, RAM or Network, I checked them all.- CPU 40% ( top command )
- RAM used 3Gb/7Gb
- Network upload Avg : 8.45 MBit/s ( Max Upload : 70.76 Mbit/s - speedtest )
So I don’t know what’s problem. Anyone can help ?
