On Heroku I got FFMPEG::Error (Failed encoding.Errors : encoded file is invalid. Full output : )
8 octobre 2020, par Ruslan ValeevThe code is :


tempfile = Tempfile.open('content')
tempfile.write(content)
movie = FFMPEG::Movie.new(tempfile.path)
screenshot_temp_file = Tempfile.open('screenshot')
movie.screenshot(screenshot_temp_file.path)


everything works fine locally, but when I try this on Heroku I got error at last row :


irb(main):013:0> movie.screenshot(screenshot_temp_file.path)

I've try to pass some options, like
:seek_timeandvalidate: falsebut nothing changed. What am I doing wrong ? Thank you so much !

EDIT :
After
Full output: )there is nothing.
I've install FFMPEG buildpack on Heroku, and can see it in ui :

Why AudioSegment doesn't read 'mp3' ?
22 octobre 2020, par freshITmeatI tried to read file that I give with absolute path.
When I run my code first that I see is this message :


D:\prog\datascience\anaconda\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
 warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)


I tried this :


PATH_TO_FFMPEG = 'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
pydub.AudioSegment.converter = r'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'


And I separately installed
ffmpegwithpip. But it didn't help.
When I try this :

raw_sound = pydub.AudioSegment.from_mp3(file=track_path)


where
track_pathis correct absolute path generated automatically.
So I got this this error :

Anomalie #4546 : image_recadre perd l’EXIF de rotation
19 septembre 2020, par jluc -Le 19/07/2020, cerdic dit «
On pourrait envisager que conserver les exifs à travers chaque filtre image, mais c’est aussi dangereux du point de vue des données personnelles. Je verrais plutôt un filtre qui permettrait de recopier certains exifs d’une image source sur l’image finale, sur le mode :<span class="CodeRay">[(#FICHIER|image_reduire{…}|image_recadre{…}|image_copie_exif{#FICHIER,’author’})]
</span>
