  • Other interesting software

    13 April 2011, by

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • "Uncurve" Cinerama-like videos

    2 August 2021, by silent

    I'm pretty new to ffmpeg and I recently found interesting videos that are trying to simulate the Cinerama technology back from 1950x by curving the final video.

    


    Here is the screenshot how it looks like during the playback: https://imgur.com/undefined

    


    I was wondering if it's possible to make this kind of picture back to "normal" rectangular shape?
Here's a small (30 seconds, 48MB) example of how it looks like: https://ufile.io/8b0139j0

    


    Thanks!

    


  • avconv video from single jpg and ogg [migrated]

    25 March 2013, by pluke

    I have a long ogg sounds file that I want to put on youtube, I don't have a video so want to display a single jpg for the duration for the ogg. I've seen:

     avconv -i "sound file.ogg" -i cog.jpg out.avi

    I have adjusted the jpg to be 640 x 480 but I get the following warnings:

     Incompatible pixel format 'yuvj420p' for codec 'mpeg4', auto-selecting format 'yuv420p'
    

    
 Incompatible sample format 's16' for codec 'ac3', auto-selecting format 'flt'
    
 [ac3 @ 0x18ae340] invalid bit rate

    And it bombs out on:

     Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    Any ideas on what parameters I could use to make this work?

  • FFMPEG change Tone Frequency (Pitch Audio)

    16 September 2022, by dazzafact

    How can I change the Tone frequency.
This Example only pitches it by keeping the old tone frequency and only decrease the length of File.

    


    For Example, I have a constant 100 Herz tone (as mp3) and I want it to change 90 Herz

    


     ffmpeg -i 100h.mp3 -af atempo=100/90 90h.mp3


    


    This Example doesn't work for me, it sounds the same

    


    inputfile Mp3
    
outputfile Mp3
