  • ffmpeg Padding & Delay to Audio File Accurately

    14 avril 2022, par Ry-

    Recently I've been doing a personal project which does entail a little bit of
audio handling but I have noticed that the commands that I am using to modify
don't have a 1:1 correlation in the resulting file leading to it being fairly
offbeat (Note that this program is error sensitive).

    


    All I need to do is accurately add Padding to the start of an audio file, or
jumpforward to some point in the song using an Offset/Delay value. The values
are strictly accurate such as 0.13149s however accuracy passed the third radix
is pretty redundant since 'nobody' should be able to notice it.

    


    Here is an example of one issue:

    [Input File Info] // This is a test case/correct values
    Supposed to start at : 0.875
    Originally started at: 1.190
    Offset Value         : -0.315
    Difference           : 1.190 - 0.875 = 0.315


    


        // Audio file offset attempt (FAIL)
    FFMPEG Command:  
        ffmpeg -y -i "..." -ss 0.315 -c copy -map 0 "..."
        
    [Output File Info]
    Start Time Beat         : 0.766 
    Start Time Beat Audacity: 0.766
    Resulting Error         : 0.106


    


    What I want to know is if someone knows a better way to get 1:1 accuracy from
the command or atleast as close to it as possible. I don't often use ffmpeg so
I probably am missing vital information (I did my best googling ok :) but to
this I also wouldn't abstain from using a dedicated audio library for the
language I'm writing the program in (Java).

    


    I probably should mention that I have been using:
    ffmpeg -y -i "..." -af "adelay=DELAY" "..."

to add the padding but I haven't really gotten around to testing audio files
that require this yet so I don't know if its broken/inaccurate.


    


  • Record Desktop Audio, Microphone Audio, and Desktop Video with FFMPEg [closed]

    16 juillet 2022, par Mypantsrtooobig

    I have a personal project where I am trying to use FFmpeg as a custom screen recorder on my computer.

    


    I managed to make a command that records my microphone audio and desktop video and a different one to record my desktop video and audio but not one that does all three.

    


    ffmpeg -f gdigrab -video_size 1360x768  -i desktop -f dshow -i audio="virtual-audio-capturer" -i audio="Microphone (Logitech G432 Gaming Headset)"  D:\Untitled\attempt.mkv


    


    If my idea is not possible can I make a command that can record all three at the same time and merge them into one .mp4 file ?
this is the command that I would think to work but it does not.
I would appreciate any help, thank you.

    


  • Random Weird HLS generation with ffmpeg

    16 août 2022, par user15006279

    I am doing some live streaming setup for my personal project and I noticed that sometime ffmpeg will not generate any hls auto it was running. I copied the same command and run in shell and it was generating HLS files successfully but somehow it was not generating with nginx.

    The more weird thing is that if i restart nginx for like a couple of times, it will regenerate. I am only playing youtube video from browser somehow ffmpeg process is not generating hls. Even after a couple of restarts, it will generate sometimes but its random. Mostly not generating at all. Can you guys help me with it ?
