  • Is it possible to change volume with no reencode with ffmpeg ?

    30 juin 2023, par John Smith

    I just had this question because I used the following command with ffmpeg :

    



    ffmpeg -i input.wav -filter:a "volume=0.2" output.wav


    



    Following the documentation here : https://trac.ffmpeg.org/wiki/AudioVolume

    



    However, when I created the new file, the output was half the size of the input and the bitrate of the audio track was reduced as well.

    



    So my questions are :

    



      

    1. Is the bitrate supposed to decrease with decreasing and increasing volume like so ?
    2. 


    3. Is it possible to change volume without reencoding with ffmpeg ?
    4. 


    


  • Why do the results of my "ffmpeg -ss -to" split have audio but no video ?

    10 avril 2018, par BenKnght

    I am trying to split clips into short intervals (that I am reading in from a csv) using ffmpeg. The commands that I’m using look like this :

    ffmpeg -i filename.mp4 -ss 00:00:00.030000 -to 00:00:02.030000  
    -pix_fmt yuv420p -c copy new_filename.mp4

    This successfully splits the parent mp4 into many smaller mp4s, but the smaller files lose some or all of their video. Most of them end up being just audio. Some have video - but only for about half of the clip (the rest is black). The audio is always there. Any ideas why this might be happening ?

    A couple notes : I’m using ffmpeg 3.0.2. Also, I am creating this command as a Python list and running it with the following call

    subprocess.run(cmd, stderr=subprocess.STDOUT)
  • creating simple DVD structure ?

    24 mars 2016, par Rambo Actionha

    I’m trying to make a DVD builder using C# , and I know that DVD’s have a specific structure which I tried to find and I couldn’t see any thing helpful , however , I found some half-completed posts about this structure , which indicate the following :

    • all DVD videos must be in ’.VOB’ format
    • all DVD Videos must be in a folder named "VIDEO_TS" and DVD audios in a folder named "AUDIO_TS" (specifically)
    • "VIDEO_T" and "AUDIO_TS" must be burned to a DVD disk that follows a special filesystem called [UDF][1]

    My question is If I managed to convert my video to suitable ".VOB" format , then I burn it to a disk after adding it to those folders , would it be playable in any DVD player ? I mean is this enough to have a simple DVD disk , and if it wouldn’t .. what would be the simplest DVD structure I can make ( without menus and chapters and other extra stuff ) ? any links related to DVD would be great
