  • Mute parts of Wave file using Python/FFMPEG/Pydub

    20 avril 2020, par Adil Azeem

    I am new to Python, please bear with me. I have been able to get so far with the help of Google/StackOverflow and youtube :). So I have a long (2 hours) *.wav file. I want to mute certain parts of that file. I have all of those [start], [stop] timestamps in the "Timestamps.txt" file in seconds. Like this :

    



       0001.000 0003.000
   0744.096 0747.096
   0749.003 0750.653
   0750.934 0753.170
   0753.210 0754.990
   0756.075 0759.075
   0760.096 0763.096
   0810.016 0811.016
   0815.849 0816.849


    



    What I have been able to do is read the file and isolate each tuple. I have just output the first tuple and printed it to check if everything looks good. It seems that the isolation of tuple works :) I plan to count the number of tuples (which is 674 in this case) and put in a 'for loop' according to that count and change the start and stop time according to the tuple. Perform the loop on that single *.wav file and output on file with muted sections as the timestamps. I have no idea how to implement my thinking with FFMPEG or any other utility in Python e.g pydub. Please help me.

    



       with open('Timestamps.txt') as f:
   data = [line.split() for line in f.readlines()]
   out = [(float(k), float(v)) for k, v in data]

   r = out[0] 
   x= r[0]
   y= r[1]
   #specific x and y values
   print(x)
   print(y)


    


  • how to create video from ffmpeg ?

    4 mai 2020, par Hong

    I have 10 images, 2 videos(mov, mp4) and 1 audio.

    



    My plan is

    



      

    1. create images to video (images.mp4)

      2. 


    



    ffmpeg -framerate 0.75 -pattern_type glob -i '*.png' \
 -c:v libx264 -vf "format=yuv420p,pad=ceil(iw/2)*2:ceil(ih/2)*2" -r 30 -pix_fmt yuv420p out.mp4  


    



      

    1. concat videos
filelist :

      2. 


    



    file 'images.mp4'
file 'video1.mov'
file 'video2.mp4'


    



    2-1 )
ffmpeg -f concat -safe 0 -i filelist.txt -auto_convert 1 -c copy output.mp4

    



    2-2 ) first. i'm encode mov to mp4. and change filelist.txt

    



    file 'images.mp4'
file 'video1.mp4'
file 'video2.mp4'
ffmpeg -f concat -safe 0 -i filelist.txt -auto_convert 1 -c copy output.mp4


    



      

    1. add background music.
It has not yet reached this stage.
It's blocked in plan 2.

      2. 


    



    this plan is right ?
I'm not sure about this plan.

    



    Step 2 output is strange.
The frame of the video No. 1 and No. 2 is not smooth.

    



    How can I create video from images and meger another video.

    


  • Attempting to compile FFmpeg 4.2.3 statically for Windows 10 (x86_64), but binaries asks for missing DLLs

    29 mai 2020, par Expectator

    I am using Msys MinGW (x86_64) and pulled a snapshot of the latest major release of FFmpeg off of their website. Here is my ./configure options. I plan to use the binaries on both the computer that I compiled it on, and other Windows computers that I own.

    



    ./configure --enable-libaom --enable-avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libgme --enable-libmfx --enable-libkvazaar --enable-libmp3lame --enable-libilbc --enable-libvpx --enable-libmodplug --enable-version3 --enable-nonfree --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libfdk-aac --enable-libopenh264 --enable-libopenjpeg --enable-nvenc --enable-nvdec --enable-cuda --enable-cuvid --enable-libtwolame --enable-vapoursynth --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxavs2 --enable-gpl --enable-static --disable-shared


    



    Output of configure script (pastebin)

    



    Output of uname -a (in Msys)

    



    MINGW64_NT-10.0-18362 <scrubbed> 3.1.4-340.x86_64 2020-05-22 08:28 UTC x86_64 Msys&#xA;</scrubbed>

    &#xA;&#xA;

    The issue that I'm facing is that despite passing the options --enable-static and --disable-shared, the executables generated still require libchromaprint.dll, libfdk-aac-2.dll, and libgme.dll to run. What I expected was that FFmpeg would execute independently of any DLL files since I passed those options to ./configure.
