  • ffmpeg how can I get the overlay to apply to all images in the slideshow

    7 avril 2022, par user2785245

    This command applies the overlay image to only the first image of the slideshow series. I messed with labeling and can't figure out the correct labels to get the overlay to apply to all images in the video.

    


    /opt/bin/ffmpeg -y -framerate 1/3 -start_number 1 -i %01d.jpg -i $watermark.png -filter_complex "pad=500:500:(500-iw*min(500/iw\,500/ih))/2:(500-ih*min(500/iw\,500/ih))/2:color=white,overlay=250:420" out.mp4 2>&1


    


  • Buid Exoplayer with ffmpeg extension

    22 février 2021, par Bhoomi Kalavadiya

    I'm making IP streaming android application. In which I'm using exoplayer 2.12.0. Input video is having mpeg-L2 audio layer codec which is not supported by exoplayer https://github.com/google/ExoPlayer/issues/6525. So i'm using ffmpeg extension to render audio.
    
I have followed https://github.com/google/ExoPlayer/tree/release-v2/extensions/ffmpeg steps to build ffmpeg extension with android-ndk-r21d-linux-x86_64 and FFmpeg-release-4.3.
    
Added code in the application
    
TrackSelector trackSelectors = new DefaultTrackSelector(new AdaptiveTrackSelection.Factory()); RenderersFactory renderersFactory=new DefaultRenderersFactory(this,EXTENSION_RENDERER_MODE_ON,DEFAULT_ALLOWED_VIDEO_JOINING_TIME_MS); player = ExoPlayerFactory.newSimpleInstance(this, renderersFactory,trackSelectors);

    
Still audio is not coming and the log is as below

Here, With or without ffmpeg extension, I'm not getting audioEnabled log in Eventlogger.
Also after using ffmpeg audio render, I'm not getting it is being used or not.
Or am I missing some configuration of ffmpeg extension to Exoplayer ?
