  • I use ffmpeg to encode and create MPEG file from a source MP4 file. In Mac the encoding is good but in windows it creates random green pixels [closed]

    24 mai 2024, par Amudhan R

    I use ffmpeg 3.4.2 version to encode and create an MPEG-TS file using H.264 encoding. In both Windows and Mac the ffmpeg creates the video without any error. But the resultant video from windows having a green pixels on certain frames. No idea why this is happening.

    


    Below is the encoding command :

    


    ffmpeg -i VIDEO_SOURCE.mp4 -vf scale=720:480 -c:v libx264 -b:v 2M -minrate 2M -maxrate 2M -bufsize 2M -level:v 40 -profile:v main -bf:v 2 -r 30 -crf 22 -x264-params 'keyint=3:min-keyint=3:ref=2:8x8dct=0:weightp=1:subme=6:rc-lookahead=30' -c:a aac -b:a 130k -ar 48000 -f mpegts -filter_complex alimiter=level_in=1:level_out=1:limit=0.15:attack=7:release=100:level=0 VIDEO_ENCODED.mpeg

  • How to convert in-memory WebM audio file to mp3 audio file in Python ?

    19 juin 2022, par Denis Ivanenko

    I am trying to convert the audio file in WebM format into MP3 file. I need to keep both files in memory due to server limitations. I tried to do it using PyAv, but I can't manage to receive Python file-like object after processing stream.
My attempt :

    


        with av.open(webm_file, 'r') as inp:
        f = SpooledTemporaryFile(mode="w+b")
        with av.open(f, 'w', format="mpeg") as out:
            out_stream = out.add_stream("mp3")
            for frame in inp.decode(audio=0):
                frame.pts = None
                for packets in out_stream.encode(frame):
                    out.mux(packets)
            for packets in out_stream.encode(None):
                out.mux(packets)


    


    webm_file is of SpooledTemporaryFile type, but I can`t get outfile as file-like, can anyone help ?
