• Java, FfMPEG : Gson not found even though it's there.

  19 avril 2018, par We are Borg

  I am working on a Spring-MVC application in which we are using FFProbe to get media information. Unfortunately, it’s not working on our live instance. We have ffmpeg & ffprobe installed on same path. The error we get is GSON is not foudn, although we have it.

  Error log :

  Caused by:

  Usage :

  Error thrown on first line.
  
  FFprobe ffprobe = new FFprobe("/usr/bin/ffprobe");
  
  FFmpegProbeResult probeResult = ffprobe.probe(filePath);

  I can confirm that ffprobe file is available on /usr/bin. What am I doing wrong here ? Thank you.

• MoviePy ImageSequenceClip doesn't create a video with transparent background even though the images have transparent background

  20 août 2020, par Emilio

  Expected Behavior

  


  I am creating a video using moviepy ImageSequenceClip. The input are the images found on this link : https://drive.google.com/drive/folders/1hQ3pfGPMvDAijS4IUcbu5hVy_HmrfCOh?usp=sharing.

  


  All the images are png and have some pixels with the alpha channel set to 0 (the background is transparent).

  


  The created video should keep those background pixels with alpha channel set to 0 (the video background should be transparent).

  


  Actual Behavior

  


  The created video is not transparent. The background pixels show their RGB values.

  


  Steps to Reproduce the Problem

  


  "images" folder should contain this images : https://drive.google.com/drive/folders/1hQ3pfGPMvDAijS4IUcbu5hVy_HmrfCOh?usp=sharing.

  


  import moviepy.editor as mpy

clip = mpy.ImageSequenceClip("images", fps=24, with_mask=True)
clip.set_opacity(0)
clip.write_videofile("video_test.mp4")


  


  Specifications

  


  Python Version : 3.7
Moviepy Version : 1.0.3
Platform Name : MacOS Catalina
Platform Version : 10.15.6
I also tried it with Docker using this image and the issue was still there : tiangolo/uvicorn-gunicorn-fastapi:python3.7
