FFMPEG waveform transparent, background solid color
11 mai 2016, par user1152226I am trying to generate a waveform with ffmpeg, I want the background to be a solid color, and the actual waveform to be transparent. The following achieves partially what i want, except that in has a black background. I would like to be able to change this to any color, but have the waveform be transparent. How can i achieve this with ffmepg ?
ffmpeg -i input.mp3 -filter_complex \
"[0:a]aformat=channel_layouts=mono,\
compand=gain=-6, \
showwavespic=s=600x120, \
colorchannelmixer=rr=1:gg=0:bb=0:aa=1,\
drawbox=x=(iw-w)/2:y=(ih-h)/2:w=iw:h=1:color=red,\
format=rgba,\
colorkey=#ff0000" \
-vframes 1 output.pngThis generates this waveform : the background is black, the waveform itself is transparent. How do I change the background color to a different color, while still keeping the waveform transparent ?

Using ffmpeg shared library in a commercial C/C++ application
9 mai 2017, par PeterWe have a C++-based application that runs on Windows, Mac, and Linux. I now need to add h.264 and h.265 decoding within this application. It seems ffmpeg will do the trick.
As ours is a commercial application, we cannot disclose the source code to public. However, as I understand, FFMpeg is based on LGPL licensing requirements. Going through various articles on LGPL requirements, it seems I can use ffmpeg without disclosing our source code as long as :
- I build ffmpeg as a shared libraries and make sure that I don’t use "—enable-gpl" flag during configuration.
- I acknowledge in our About dialog box that we are using ffmpeg shared libraries.
Can someone please verify if this more or less meets the requirements ? Regards.
Note that I need ffmpeg only to decode and not to encode. Therefore, I don’t have to use "—enable-libx264" and "—enable-libx265" flags.

ffmpeg -pattern_type glob not working in Google Colab
22 février 2023, par John JannoneI'm trying to combine images into video using ffmpeg in a Google Colab Notebook ; I'm getting errors but don't see what I'm doing wrong.


!ffmpeg -pattern_type glob -i 2023021522* -c:v libx264 video2.mp4


returns : Option pattern_type not found.


!ffmpeg -pattern_type glob -i '2023021522*' -c:v libx264 video2.mp4
or
!ffmpeg -pattern_type glob -i "2023021522*" -c:v libx264 video2.mp4


return : 2023021522* : No such file or directory


I also tried adding
from glob import glob
and justimport glob
