    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Merging two audio files in Android using FFMPEG

    1er juillet 2021, par Jeremy

    I'm working on an application that takes two audio files, and merges them into the respected channels. The way they are being equalized are not as good as I had hoped, So I want to adjust the volume of each file during the mixing phase. I've seen a couple of examples online, like this, this, and [this][3].. but none of them are working for me. Can someone direct me in the right direction with this ? Much appreciation !

    



    I am using this library to execute : https://github.com/WritingMinds/ffmpeg-android-java

    



    Here is my code (EDIT)

    



    String files = "-i " + mVoiceFile.getAbsolutePath() + " -i " + mBeatFile.getAbsolutePath();
String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2][a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0

    



    enter code here

    



    and here are my errors from running.

  • Using ffmpeg to display a static image if an RTMP input source is missing

    19 mars 2016, par iameli

    Here is what I would like ffmpeg to output :

    • If I am streaming from my iPhone to my RTMP server, ffmpeg should output the live video from my iPhone.
    • If not, ffmpeg should output a blank red screen.

    Here’s what I have so far. It sort of works.

    ffmpeg \
    
  -f lavfi \
    
  -re \
    
  -i 'color=s=320x240:r=30:c=red' \
    
  -thread_queue_size 512 \
    
  -i 'rtmp://localhost/stream/iphone' \
    
  -c:v libx264 \
    
  -f flv \
    
  -filter_complex "\
    
    [1:v]scale=320:240[stream]; \
    
    [0:v][stream]overlay=0:0:eof_action=pass[output] \
    
  "\
    
  -map '[output]' \
    
  -tune zerolatency \
    
  'rtmp://localhost/stream/output'

    What happens : it boots up and starts streaming my iPhone’s output no problem. When I disconnect, it hangs for a long time, perhaps 20 seconds. Then it starts outputting red, okay. But then if I reconnect my phone, it doesn’t resume. It’s still red. Two questions :

    • Is there a way to configure the buffering so that it starts outputting red as soon as it stops getting data from the RTMP stream ?
    • Is there a way to have it auto-retry, so after the RTMP stream returns, it will switch back ?

    Full verbose output, if that’s helpful. I’m using the latest git version of ffmpeg as of 2016-03-18 on Ubuntu Wily. The RTMP server is nginx-rtmp.

  • ffmpeg didn't execute commands correctly - android

    18 mars 2016, par BOB

    I’m using ffmpeg to draw text on video, i following the instruction in http://hiteshsondhi88.github.io/ffmpeg-android-java/

    and i’m successfully install ffmpeg library in my application, but when i’m run any command it’s Start the process and appear this lines in android monitor

    Metadata :

    creation_time : 2016-03-03 14:29:38

    handler_name : Stereo

    Then nothing happen

    and create the output video with 00:00 byte and 00:00:00 time

    can any one help me to avoid this error

    I think it’s losing metadata while encoding

    My Command that i use is

    ffmpeg -i "+inputvid+" -vf enable-libfreetype \"drawtext=enable='between(t,12,3*60)':fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf:text='TestText'\" -acodec copy "+outvid+""

    Thanks
