  • flutter-ffmpeg error on mixing audio and picture - Unable to find a suitable output format for 'ffmpeg

    18 juillet 2021, par tylyo

    I'm trying to mix an audio and a picture in order to have a video with the same length of the Audio and as content an image sequence of the source picture.

    


    I tried using the flutter-ffmpeg plugin with the command :

    


    ffmpeg command: ffmpeg -loop 1 -i '/data/user/0/com.attiliopatania.apshare/cache/file_picker/20210402_112326.jpg' -i '/data/user/0/com.attiliopatania.apshare/cache/file_picker/Voice001.m4a' -c:v mpeg4 -tune stillimage -c:a copy -shortest /data/user/0/com.attiliopatania.apshare/app_flutter/out.mp4


    


    some context :

    


    I did the same test with ffmpeg on my pc and it worked as expected. I liked it.

    


    I did some test and I tried to write a file on the same path where the out file should be and It worked as expected : file created

    


    Running the same command through flutter plugin I experienced an error I'm reporting below

  • Even after converting the Audio from Mono to Stereo in ffmpeg the video still has No sound Unless

    19 février 2021, par Mariah242

    I Change the audio Mode in VLC from Stereo to Mono then the Audio will play Normal

    


    I used ffmpeg to convert the audio to Stereo using this

    


    ffmpeg -i bokan_test_1.mkv -map 0 -map -0:s? -c:v copy -c:a ac3 -ac 2 -b:a 640k "E:\Test\output.S01E05.mkv"


    


    I even used Handbrake still No audio in VLC unless I change the audio mode to Mono

    


    Edit :
full log when running the ffmpeg command above

    


    E:\test audio>ffmpeg -i bokan_test_1.mkv -map 0 -map -0:s? -c:v copy -c:a ac3 -ac 2 -b:a 640k "E:\Test\output.S01E06.mkv"

    lavu/pixfmt : Update the description for AV_PIX_FMT_QSV

    Since D3D11 was introduced for QSV in FFmpeg 5.0, there is an implied
    
API/ABI change for user-supplied frames [1], hence update the
    
description for AV_PIX_FMT_QSV.
