  • ffmpeg : Make output file duration that of the file with the longest length [closed]

    27 février 2024, par losercantcode

    I'm going crazy trying to figure this out.

    


    Essentially I'm trying to apply sidechain compression using ffmpeg (for the sake of speed and automation). a2.mp3 in this example is the full length track and a1.wav is a short 5 second, spoken-word clip. The code currently applies the sidechain compression well, but the output file is only that of the spoken-word clips length, so 5 seconds. Is it at all possible to make the output match that of a2.mp3's length instead ? Switching around the input order is not something that's possible as it'll apply the compression to the incorrect track.

    


    Essentially, i'm trying to make it so i'm just layering the spoken-word file on top of the audio track without having to pre-pad the file. I'd rather, if it's possible, this just happen with one block of code within the in one program. I'm interested to see if this is at all possible within ffmpeg.

    


    ffmpeg -i a2.mp3 -i a1.wav -filter_complex "[1:a]asplit=2[sc][mix];[0:a][sc]sidechaincompress=threshold=0.000976563:ratio=10:level_sc=0.015625:release=100:attack=10[compr];[compr][mix]amix=duration=longest[aout]" -map "[aout]" output.wav


    


    a1.wav is mon, a2.mp3 is stereo.

    


    Attempted to implement amix=duration=longest to no avail. Research similar problems on the Stack Exchange that gave unrelated answers.

    


  • Compiled file for ffmpeg - iphone audio

    3 avril 2012, par Sreekumar Kalarikkal

    I would like to build an iPhone application which streams internet radio stations which includes .wma files also. So I found that in-order to play wma files, we need FFMPEG compiled files. I tried to build FFMPEG for iPhone, but having errors. I followed the guide here,

    I can able to build ffmpeg, but when I run the project using that library, I am getting the following error.

    So I think anybody of you may be successfully compiled and used this. If yes please give me some instructions to do this.

    Or if you can find the solution for the error. please let me know.

  • iPhone - IMA WAV ADPCM audio stream for iOS

    21 mai 2013, par Siriss

    I am trying to write an app for a school project that will play a video stream of the lab. They use Foscam cameras, and from what I understand they only stream audio in FFMPEG and VLC (a wrapper of FFMPEG and others, correct ?). I can play the video stream in a UIWebView just fine, but I can't figure out how to get audio to work. I have read a bunch of post on here about the different audio stream options, but none support this format. I have also looked into VLCKit, but that seems to only work in OS X, not iOS.

    Is there a Framework, or Kit that can stream IMA WAV ADPCM audio from a VLC/FFMPEG file, or does someone know of a better way to get audio from a Foscam ?

    EDIT - I know more about the stream and I have tried a few things. I tried AVPlayer, but discovered Audio FIle Stream and Audio Queue Services but can't find a good tutorial.

    I also found THIS site, and tried the project with my stream and it did not work.
