  • FFMPEG incorrect image extension fails coding [closed]

    14 novembre 2016, par G.T.

    I have a problem using ffmpeg on images. My problem is that quite a lot of images on the internet has incorrect extension ( png files names .jpg and jpg files named .png) which makes the ffmpeg fail.

    I couldn’t find any documentation on the internet how can this be fixed ? Can I force somehow ffmpeg to try to look in other codec types too not just the ones the extension suggests ?

    To reproduce this you just need to download a png from the internet and rename it’s extension to .jpg

    And even if you use the simplest command like ffmpeg -i image.jpg it fails with :

  • running multiple FFmpeg instances to encode udp stream gives error

    24 mars 2014, par user2854116

    Please someone help me to fix the problem below

    I am trying to encode multiple udp streams in HLS format. I run one by one instance (process) of encoding on the system. The application is working fine and I was able to encode, receive and play the streams using a player running on a STB (Set Top Box). The encoding was OK till running the 5 th instance. When I started running the 6th encoding instance on the system, the stream output starts freezing in all the 6 encoded outputs.

    I am using a Intel Xeon based Server with 24 cores and 32GB of RAM.

    Here is my ffmpeg build info.
