• Extract Wavelength from MP3 as an Image

  13 mai 2016, par Dan

  Are there any good libraries that can help convert an MP3 into an image of its wavelengths (I think that’s the proper term). What I’m looking for is a way to generate the wavelengths of MP3s server-side like is done on Souncloud : http://soundcloud.com/smixx/takin-vc-money-money-cash-ipos

  What would be the best approach to extact that type of image from an audio file ?

• missing audio of second video after combining video

  27 mai 2021, par JohnTerry

  I am trying to add xfade filter and the command is working but audio of second video is missing in output video.

  


  command is -

  


  ffmpeg -i 1.mp4 -i 1.mp4  -filter_complex "[0:v]scale=480:360:force_original_aspect_ratio=decrease,pad=480:360:-1:-1,setsar=1,fps=30,format=yuv420p[v0];[1:v]scale=480:360:force_original_aspect_ratio=decrease,pad=480:360:-1:-1,setsar=1,fps=30,format=yuv420p[v1];

• why ffmpeg only combines first 390 images when combining very large amount ( about 9k) images into video ?

  4 juillet 2021, par Siwei

  I have a VCD, and I split it into nearly 10,000 images, named like :

  


  $ ls tmp_enlarged_image_folder

vcd3_00000001.png
vcd3_00000002.png
vcd3_00000003.png
vcd3_00000004.png
...
vcd3_00089998.png
vcd3_00089999.png
vcd3_00090000.png


  


  and the following command doen't work for me :

  


  ffmpeg -loglevel trace -f image2 -r 25 -pattern_type sequence -i 'tmp_enlarged_image_folder/vcd3-%08d.png' -vcodec libx264 test.mp4
