  • how to adjust the thumbnail size with ffmpeg while get a screenshot from an video

    15 novembre 2022, par Bill Wu

    I am trying to get a thumbnail from a video with ffmpeg

    


    the command I tried is :

    


    ffmpeg -i zzz.mp4 -ss 00:00:03  -f image2 foobar.jpeg


    


    and this command works fine, except that the resolution is 1920 * 1080 by default.
while in my scenario, I've prefer a smaller picture, say 300 * 300.
in this answer, Jeff Ward suggests the command :

    


    ffmpeg -ss 00:00:01.00 -i input.mp4 -vf 'scale=320:320:force_original_aspect_ratio=decrease' -vframes 1 output.jpg


    


    but the picture produced seems garbled on my linux, i dont' know why, is there any other parameter that maybe available for this ? Thanks in advance.
foobar.jpeg

    


  • librosa can't load wav file in aws lambda docker

    30 novembre 2022, par Luka Savic

    I have an AWS Lambda function created using Docker.
I have librosa installed, ffmpeg installed using the solution from this question : install ffmpeg on amazon ecr linux python

    


    I checked in a Lambda function with os.system("ffmpeg -version") and I managed to get valid output, stating different versions and parts of ffmpeg.

    


    Problem is that when I do librosa.load(wav_file) it gives the following error :

    


    /your/path/.venv/lib/python3.9/site-packages/librosa/util/decorators.py:88: UserWarning: PySoundFile failed. Trying audioread instead.
  return f(*args, **kwargs) 


    


    From what I've read, librosa should natively support .wav files, even without ffmpeg, and even though I have ffmpeg installed, it doesn't work.

    


    One more information, .wav file was downloaded, player, and loaded with librosa on my local PC without any problems. I tried also on different wav and mp3 files, and the problems were still there.
