  • Récupération d’informations sur le site maître à l’installation d’une instance

    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Combining Video and Audio of different length in bulk

    27 avril 2017, par user2981223

    I am going through a tv series right now and editing the files to be to my liking. I have one set which has the video I want and one set that has the audio. I have a batch file that I can run that takes the video from every file in folder "A" and the audio from every file in folder "B" and outputs it to a folder named "output." But with this particular series, that is only half of what I need done.

    At the end of every episode of the files in the "B" folder there are some extra things. What I would like to do is take the audio and video from "A" and the audio from "B", combine it all into one file and also take the "A" and "B" files, compare the time stamps, and add the extra video from "B" to the output file.

    Let me put it another way. Let’s say "A" is 1080p with Japanese audio and is 20 minutes long. Let’s say "B" is 720p with English audio and is 23 minutes long. I want the whole 1080p video with both audio tracks, plus the 720p video spliced onto the end. Both files start at the same spot so syncing isn’t an issue. The issue is that the difference in time is different for every episode. So some episodes are 3 minutes longer, some only 30 seconds. Is there a way to make ffmpeg or another tool look at the difference in times and just add the excess to the output file ?

    Sorry for being long winded. Thanks for any help and guidance.

  • Produce waveform video from audio using FFMPEG

    27 avril 2017, par RhythmicDevil

    I am trying to create a waveform video from audio. My goal is to produce a video that looks something like this

    enter image description here

    For my test I have an mp3 that plays a short clipped sound. There are 4 bars of 1/4 notes and 4 bars of 1/8 notes played at 120bpm. I am having some trouble coming up with the right combination of preprocessing and filtering to produce a video that looks like the image. The colors dont have to be exact, I am more concerned with the shape of the beats. I tried a couple of different approaches using showwaves and showspectrum. I cant quite wrap my head around why when using showwaves the beats go past so quickly, but using showspectrum produces a video where I can see each individual beat.

    ShowWaves

    ffmpeg -i beat_test.mp3 -filter_complex "[0:a]showwaves=s=1280x100:mode=cline:rate=25:scale=sqrt,format=yuv420p[v]" -map "[v]" -map 0:a output_wav.mp4

    This link will download the output of that command.

    ShowSpectrum

    ffmpeg -i beat_test.mp3 -filter_complex "[0:a]showspectrum=s=1280x100:mode=combined:color=intensity:saturation=5:slide=1:scale=cbrt,format=yuv420p[v]" -map "[v]" -an -map 0:a output_spec.mp4

    This link will download the output of that command.

    I posted the simple examples because I didn’t want to confuse the issue by adding all the variations I have tried.

    In practice I suppose I can get away with the output from showspectrum but I’d like to understand where/how I am thinking about this incorrectly. Thanks for any advice.

    Here is a link to the source audio file.
