  • Spaces in FFMPEG Input Thwart Execution

    2 septembre 2021, par Woolwit

    What's so baffling, is why spaces in the audio input seem to work fine, but spaces in the video input break things.
This fetches random images from a directory, pairs them with random audio clips and joins them into an mp4 video.

    


    def makeAudioImgMovs():
    randImgs = getImgs()
    compAudClips = makeAudioClips()
    audioJpgs = dict(zip(randImgs,compAudClips)) #Heres where we join the completed audio clips and the jpgs into a dict
    for jpg, aud in audioJpgs.items():
        print(f'The img is {jpg}, the type of the img is {type(jpg)} the aud is {aud} the type of the aud is {type(aud)}')
        subprocess.call('ffmpeg -hide_banner -loglevel error -loop 1 -i "{0}" -i "{1}"\
        -filter:v \
        "fade=in:st=0:d=1, fade=out:st=10:d=1,scale=720:480:force_original_aspect_ratio=decrease,pad=720:480:(ow-iw)/2:(oh-ih)/2,setsar=1" \
         -filter:a "afade=in:st=0:d=1, afade=out:st=10:d=1" \
        -c:v libx264 -t 11 -pix_fmt yuv420p -preset faster -shortest -c:a aac {2}.mp4'.format(jpg,aud,timePath/(pathlib.Path(jpg).stem)),shell=True)
makeAudioImgMovs()


    


    The print statement is writing what is in the dict of audioJpgs list. For example...

    


    The img is 2021-09-02-1-40/ponty_me.jpg, the type of the img is the aud is 2021-09-02-1-40/Jms Brn like it is like it was.aiff the type of the aud is

    


    The img is 2021-09-02-1-40/1966taxiToMassFromMomBack 2.tiff, the type of the img is the aud is 2021-09-02-1-40/Lola_Fay.mp3 the type of the aud is

    


    [NULL @ 0x7fe503021400] Unable to find a suitable output format for '2021-09-02-1-40/1966taxiToMassFromMomBack'
2021-09-02-1-40/1966taxiToMassFromMomBack : Invalid argument

    


    The img is 2021-09-02-1-40/1966taxiToMassFromMomBack 5.tiff, the type of the img is the aud is 2021-09-02-1-40/M Miller Lonnie's Lament.aiff the type of the aud is

    


    [NULL @ 0x7fd32a854c00] Unable to find a suitable output format for '2021-09-02-1-40/1966taxiToMassFromMomBack'
2021-09-02-1-40/1966taxiToMassFromMomBack : Invalid argument

    


    The img is 2021-09-02-1-40/10_021390_danny ? 1_jpg.jpg, the type of the img is the aud is 2021-09-02-1-40/i_got_to_rock.mp3 the type of the aud is

    


    [NULL @ 0x7f8449835800] Unable to find a suitable output format for '2021-09-02-1-40/10_021390_danny ?'
2021-09-02-1-40/10_021390_danny ? : Invalid argument

    


    The img is 2021-09-02-1-40/11_021390_danny_2_jpg.jpg, the type of the img is the aud is 2021-09-02-1-40/M Miller Power.aiff the type of the aud is

    


    The last pair of img/aud complete fine and write an mp4. Notice there, that the audio file has spaces in it !
Notice that the errors 'Invalid argument' get thrown where there is a space in the jpg file name.

    


    Help greatly appreciated.

    


  • Can FFmpeg crop gif image under 1 second ?

    5 septembre 2021, par jeongbalmountain

    I am developing an iOS application about gif.

    


    But I have a problem with gif cropping. Cropping gif spends so many times with FFmpeg.

    


    (updated code)

    


    These are the ffmpeg codes I've tried.

    


    cropped images -> gif

    


    ffmpeg -f image2 -i %d.jpg -vf 'scale=450:-1' output.gif


    


    using concat command (cropped images -> gif)

    


    ffmpeg -f concat -i tmp.txt output.gif


    


    using crop filter

    


    ffmpeg -i in.gif -filter:v "crop=out_w:out_h:x:y" out.gif


    


    These codes are so slow when converting images to gif
or gif to cropped gif.

    


    Is there a way to reduce the time to crop gif less than 1 second ?

    


    (updated2)
ffmpeg -i in.gif -filter:v "crop=out_w:out_h:x:y" out.gif
