    15 octobre 2018, par Julien

    I have a PHP script that converts uploaded videos to x264, it works fine if I upload an FLV, but with an MP4 it doesn’t work, here’s the command and output :

    Command :

    ffmpeg -y -i ../../flv/rjaRGKzSMtksUJ4kGbsLMYEcr.mp4 -crf 0 -vcodec libx264 -movflags faststart ../../flv/rjaRGKzSMtksUJ4kGbsLMYEcr.mp4 2>&1

    As you can see there are some errors, there. I’ve tried with several different mp4 files, from different sources so it’s not a problem of the video files.

    I’ve also tried without the -movflags faststart option, also tried with -q:v 0 instead of -crf 0, nothing works, but like stated above, it works from FLV -> MP4, what am i doing wrong here ?

    PS : By "Nothing works" I mean the resulting MP4 plays for 1 frame in the browser and stops.

  • 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 ?
