    23 septembre 2013, par user1241903

    I need to create a player which will decrypt the input on-fly and play the content.
    I have choosen ffmpeg libs (libav*) to create player and to start I have followed this link

    but audio is not playing properly,video is playing fine.
    I am using ubuntu 12.04LTS 64bit OS with the following ffmpeg version,

    admin@vz-X401A1:~$ ffmpeg

admin@vz-X401A1:~$

    and downloaded tutorial07.c from this link

    still, with this also, sound is not playing properly.

    I need help to solve the following issues,

    1. How can I fix this audio issue(I have gone through similar question in StackOverflow and installed old ver. of ffmpeg, but issue still remains).

    2. And also suggest some steps or tutorial, how to implement on-fly decryption process (in C) and integrate this with the player.

  • FFmpeg file not found exception, No such file or directory

    16 avril 2020, par Sagar

    I am getting the No such file or directory 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 the above mentioned path and in exception.

    



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