  • FFmpeg concatenates two m4a files incorrectly

    26 février 2017, par asad

    Problem is, when i concatenate two m4a files with concat demuxer, ffmpeg produces files whose duration is incorrect. You can see that the duration of output file is very different from the duration of two input files combined. Please help me spot the issue in it. My ultimate goal is to append silent audio to the end of the audio file. For that, i generate silent audio file with ffmpeg and then try to concat it with other audio file.

    Command I used to generate audio file :

    ffmpeg -nostdin -loglevel error -y -threads 0 -filter_complex aevalsrc=0 -t 4 /home/ec2-user/videocreation/temp/silence.m4a

    Command I used for concat :

    ffmpeg -f concat -safe 0 -i temp.txt -c copy output.m4a

    I have two file paths listed in temp.txt :

    [ec2-user@ip-10-0-1-126 server]$ cat temp.txt 
    
file /home/ec2-user/videoData/DnXptC4ld8/FADING_OUT_VOLUP_Blrt_Decrypt_1ed5c4d569d8a1f23428b65217f65eaf_audio.m4a

  • ffmpeg extra frames from video [closed]

    3 mai 2023, par catman30223

    Someone please tell me why the command does not work.

    


    ffmpeg -i /home/darryl/Desktop/video/video/video.mp4 -vf fps=30/60 /home/darryl/Desktop/video/video/img%03d.jpg

    


    I did chown the output subdirectory

    


    I have used that ffmpeg command hundreds of times without issue. I just don't get what is wrong with it. It keeps saying "no such file or directory"

    


    I also tried mkdir /mnt/temp and chown darryl:darryl /mnt/temp to extract the frames to that output subdirectory. The result was the same "no such file or directory"

    


  • FFmpeg file path exception like file name not found

    7 février 2018, par Sagar Hudge

    I am getting following exception on video trimming.

    video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

    file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

    and ffmpeg searching for only Fast in

    /storage/emulated/0/Pictures/Instagram/Fast: No such file or directory

    I have found the issue ,it is causing due to the file name having spaces in between them you can check in above mentioned path and in exception.

    after changing file name its working but changing name of every file from device its not the right way so how can I solve this exception
