  • Streaming trouble, ffmpeg unable to find a suitable output format

    9 octobre 2018, par Michael Munyanyi

    FFMPEG for some odd reason won’t allow me to output a stream, it’s odd because I have two computers available and one, which had low CPU was having trouble decoding but the stream worked, so I switched my network cables and I have tried transcoding with the same command and it will not output a stream.

    My command reads

    ffmpeg -i udp://@xxx.x.x.xx.xxxx -f mpegts udp://@xxx.x.x.xx.xxxx

    I also tried

    ffmpeg -i udp://@xxx.x.x.xx.xxxx udp://@xxx.x.x.xx.xxxx

    The error reads

    [NULL @ 000001c95eeb2600] Unable to find a suitable output format for udp://@xxx.x.x.xx.xxxx'
    
udp://@xxx.x.x.xx.xxxx: Invalid argument"

  • Unable to play video processed by ffmpeg

    8 janvier 2023, par Kong

    I have an issue of not being able to play a video that was processed by ffmpeg. I have 6 videos, each of different length but same frame rate that i merge (2 rows 3 columns).

    


    VLC player doesn't run it, using any other players return an error. Below is the code I used to combine the videos. I can't seem to find a solution on Google or Stack Overflow.

  • Tagline challenge : what’s in a tagline ?

    23 octobre 2018, par Joselyn Khor — Marketing

    thinking

    Our new website needs a new tagline !

    We’ve been going with the words “liberating analytics” for a few years and believe it’s time for a refresh.

    Coming up with a new tagline is leading to a few sleepless nights so we’ve decided to reach out to you guys to see if you’re up for a challenge.

    We’ve tried a few options but they don’t seem quite right, just yet :

    “Complete analytics”
    “All-in-one analytics”
    “Your analytics”
    “Beyond analytics”
    “Analytics for humans”

    We’ve gone through about 46 so far and none have stuck so we want your ideas. Are you feeling the options above, or can you (surely) come up with one even better ?

    Leave it in the comments section of our Mastodon, Facebook, Twitter pages, DM or post about it. You can also get in touch through the site ! Do whatever is necessary to let us know. Have what it takes to think of a tagline for a global analytics company ?
