替代方案 OBS - 开放广播软件

我遇到了一个问题。OBS [Open Broadcaster Software] 无法在我的笔记本电脑上运行，因为它不支持 OpenGL 3.5。我想进入现场编码，那么有没有OBS的替代品呢？

解决方案！

第一的：

安装 FFMPEG

sudo apt-get update
sudo apt-get install ubuntu-restricted-extras
sudo apt-get install ffmpeg

第二：

创建一个名为“obs-fix.sh”的文件，包含以下内容

INRES="1366x768" # input resolution
OUTRES="1366x768" # output resolution
FPS="30" # target FPS
GOP="30" # i-frame interval, should be double of FPS, 
GOPMIN="15" # min i-frame interval, should be equal to fps, 
THREADS="4" # max 6
CBR="1000k" # constant bitrate (should be between 1000k - 3000k)
QUALITY="ultrafast"  # one of the many FFMPEG preset
AUDIO_RATE="44100"
STREAM_KEY="***************************"
#SERVER="rtmp://live.twitch.tv/app/"
#SERVER="rtmp://live.justin.tv/app/"
SERVER="rtmp://usmedia3.livecoding.tv:1935/livecodingtv/"

ffmpeg -f x11grab -s "$INRES" -r "$FPS" -i :0.0 -f alsa -i pulse -f flv -ac 2 -ar $AUDIO_RATE \
 -vcodec libx264 -g $GOP -keyint_min $GOPMIN -b:v $CBR -minrate $CBR -maxrate $CBR -pix_fmt yuv420p\
 -s $OUTRES -preset $QUALITY -tune film -acodec libmp3lame -threads $THREADS -strict normal \
 -bufsize $CBR "$SERVER$STREAM_KEY"

并执行此操作脚本和./obs-fix.sh

在 ubuntu 15.10 和 16.04 中运行良好
