  • Playback FFmpeg stream through UDP

    11 juillet 2020, par Andrew Raleigh

    I'm using the following command to send ffmpeg data :

    


    ./ffmpeg -i "" -pix_fmt yuv420p -tune zerolatency -preset ultrafast -f mpegts udp://127.0.0.1:23000

    


    I then transmit and receive it to another computer through the srt protocol, and read it back on the end-point.

    


    I play back with .\ffplay.exe -i udp://127.0.0.1:23000 -loglevel 40 and don't see a video. I can see data coming in from WireShark though. This is the log output :

    FFPlay and FFProbe both output the above. Usually FFPlay would show the video playing back, but in this case I get nothing. Any thoughts as to why ?

  • Block artifacts in extracted frame using ffmpeg

    28 août 2020, par 12.yakir

    I'm extracting a single frame from a video with :

    


    ffmpeg -ss 60 -i video.mov -vframes 1 a.jpg


    


    which produces this :
image showing the artifacts
I tried manipulating the pix_fmt and the quality of the q:v 2 to no avail. Note that elsewhere in the video (i.e. not at 60 seconds, but before or after) no such artifacts are visible.

    


    The one thing that helped a little is averaging across multiple frames (adapted from here for 15 frames) :

    


    -vf tmix=frames=15:weights="1 1 1 1 1 1 1 1 1 1 1 1 1 1 1",select='not(mod(n\,15))'


    


    which looks better :
enter image description here
But still, it took a whole 15 frames to get this, and you can still see the artifacts.

    


    Is there a better way to deal with this kind of noise ?

    


    Thank you in advance !
