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 :

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 :

I've try to pass some options, like

FFmpeg psycho-visual options - psy-rdoq
7 avril 2020, par SLVRI'm new to encoding and I like to do my encodings in x265 10bit. Currently, I'm facing a little issue with ffmpeg. I noticed when I'm using libx265 encoder output file looks a little bit blurred or small detail loss. Code I used to do my encodes is



ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -c:a copy -y output-x26510bit.mkv



I've found out psycho-visual options might help in this case. I modified my code in to



ffmpeg -i input.mp4 -c:v libx265 -preset medium -crf 22 -pix_fmt yuv420p10le -psy-rd 2 -psy-rdoq 4 --rdoq-level 1 -c:a copy -y output-x26510bit.mkv



When I issue the above command, I get an error code
