  • 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.

  • How can one pipe the audio waveform image out of ffmpeg into an image display command/application? [closed]

    15 May 2022, by esp

    These two commands, when used in succession, produce a .png file of the inputted audio waveform.

    


    ffmpeg -i audioFile.mp3 -filter_complex "showwavespic=s=640x120" -frames:v 1 imageFile.png
qlmanage -p imageFile.png


    


    But I have not succeeded in piping the image from the first to the second. Simply using "|" between them did not work.

    


    ffmpeg -i audioFile.mp3 -filter_complex "showwavespic=s=640x120" -frames:v 1 |
qlmanage -p


    


    Error:

    


    Filter showwavespic has an unconnected output


    


    Sounds pretty fundamental!

    


    Please, how can what I am trying to do be achieved?

    


  • ffmpeg Muxing Recovered Files - Audio dropping

    7 April 2020, by Chris McL

    A few years ago, we accidentally deleted all our home movies. We recovered the files from the camera. They have lost their headers and are not playable. I have used a recovery program (recover_mp4) to get an h264 and aac file.

    



    When I try to mux these together, the audio drops off from the stream. It also crackles badly at times. If I play the AAC file by itself, it sounds fine. For some movies, the audio works for a while, on others it drops out quickly.

    



    One thing I noticed is that the resulting muxed mp4 file is often shorter than the audio.

    



    I've tried various ffmpeg commands that look generally like this:

    



    ffmpeg -r 30000/1001 -i recovered_video.h264 -i recovered_audio -bsf:a aac_adtstoasc -c:v copy -c:a copy output.mp4

    



    Any ideas on how to marry the two files together?

    


  • "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!
