  • Streaming to YouTube using FFmpeg Problems

    9 mai 2016, par jason

    I am trying to stream to a live event I have created inside of YouTube. I am trying to stream a already created video. The command I am using is noted below.

    The problem I have is that YouTube is showing the Streaming status as good (picture attached) and it seems to be receiving the data. But there is no sound and no picture in the live event. I’m not sure what the issue could be.

    ffmpeg -re -y -i input.mp4 -vcodec libx264 -b:v 600k -r 25 -s 640x360 -filter:v yadif -ab 64k -ac 1 -ar 44100 -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"

    Edit -

    I have now tested the following codes but I still dotn get any picture or sound.. but the health status in youtube still shows good

    I ran this command first

    ffmpeg -i input.mp4 -vcodec libx264 -preset medium -maxrate 3000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -acodec libmp3lame -b:a 128k -ac 2 -ar 44100 file.flv

    and then I ran this

    ffmpeg -re -i file.flv -codec copy -f flv rtmp://a.rtmp.youtube.com/live2/<key>
    
</key>

    I still didnt get any picture

    I also tried the full command in 1

    ffmpeg -re -i input.mp4 -vcodec libx264 -preset veryfast -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://a.rtmp.youtube.com/live2/<key>

    I am trying to build FFmpeg source file using android ndk r8b version . My linux version is CentOs 6.5.I am following this instruction from this link https://github.com/yixia/FFmpeg-Android
    Here is bash script which is I am trying to execute

    Now i am getting this error ./FFmpeg-Android.sh: line 26: export:arm-linux-androideabi-gcc’ : not a valid identifier
    arm-linux-androideabi-gcc is unable to create an executable file.
    C compiler test failed.`

    The code in 26 number line is export CC=arm-linux-androideabi-gcc any idea why the problem is happening ?? a help would be appreciated .
