• Install gstreamer on EC2 Amazon Linux AMI ?

  6 décembre 2015, par vy32

  I’m trying to install QT5.5 on Amazon EC2 Linux, which apparently requires that I install some kind of multimedia support. It looks like that comes from gstreamer.

  yum search gstreamer turns up :

   You could try using --skip-broken to work around the problem
  
   You could try running: rpm -Va --nofiles --nodigest
  
  [ec2-user@ip-172-30-1-58 ~]$ 

  Supplying the suggested --skip-broken doesn’t help :

  [ec2-user@ip-172-30-1-58 ~]$ sudo yum install -y gstreamer-ffmpeg --skip-broken

  So how do I install gstreamer-ffmpeg ? Why aren’t the dependencies automatically being followed ?

• it's hang when using av_interleaved_write_frame

  19 avril 2018, par Eric Nguyen

  I use the ffmpeg to stream the encoded video.
  when it is streaming, it plug out the internet cable, it means connection to the serve is lost.
  the video is hangs, i can not handle after that. i see the reason that it is hang at av_interleaved_write_frame(), the function doesn’t return result or any error, it hangs forever at there.

  Anyone see that issue, and Can you help me to fix that bug.
  Thanks.
