  • How can I change what ffmpeg is displaying in real-time ?

    1er juin 2020, par Draconis

    I would like to take a variety of live video streams (from cameras, RTMP, etc), apply some filters to them, then display them on a screen. So far, ffmpeg has handled all the filtering and compositing perfectly and with very little delay.

    



    However, I'd also like to be able to swap out the streams in real-time.

    



    My first thought was to have a separate program read each stream and copy them to FIFOs, which ffmpeg would read from, filter, and display ; this separate program would then handle the "channel changing". Is this the best way to go about it ? Or is there a better solution ?

    


  • ffmpeg - executing 2 or more command in one time

    25 avril 2019, par Happy Man

    I have 2 ffmpeg commands, I execute them respectively, they work, but I want to execute them in one time and one command. How to do that ?

    ffmpeg -i 1.mp4 -i logo.png -filter_complex "overlay=main_w-overlay_w-20:20" -codec:a copy 2.mp4
    

    
ffmpeg -i 2.mp4 -i picture.png -filter_complex "overlay=10:10" -codec:a copy 3.mp4

  • real time decoding of SHVC bit streams

    8 mai 2018, par userDtrm

    Does anyone know an open source decoder that can perform real time SHVC bit stream decoding ?. The openHEVC states that it has the capability to decode HEVC scalable bit streams, but I was not able to decode a SHVC bit stream generated by SHM 7.0 reference encoder.

    Also, does the ffmpeg support scalable extension of HEVC ?.

    Thanks.
