  • Converting FFMpeg Video to android playable video

    15 April 2021, by Soham Samanta

    I had some image sequence and I used them to make a video using FFMpeg. It palyed well on VLC (windows and android) but not on built in android video player.
Codec and container info of the video is the following -

    


    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '../clg/clg_eq_final_injected.mp4':
  Metadata:
    major_brand     : isom
    minor_version   : 512
    compatible_brands: isomiso2avc1mp41
    encoder         : Lavf57.83.100

    Metadata:
      handler_name    : VideoHandler
    Side data:
      spherical: equirectangular (0.000000/0.000000/0.000000)


    


    I made a workaround by uploading the video on youtube. Then I downloaded it again. It's codec info is following -

    


    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '../clg/clg_eq_test.mp4':

    I noticed that the first video does not have any audio stream (since it's just an image sequence). But youtube arbitrarily added an audio stream. (I tried on android after adding an audio stream with it but no luck)
What I know -

    


      

    1. Android does not natively support motion JPEG.

      2. 


    2. H264 is supported by android.

      3. 


    


    Q1. What is the difference between h264(constrained baseline) vs h264(main) ?
Q2. Why the first video is not natively supported on android ?
My uploaded youtube video is here.

  • ffmpeg Live Streaming Error : av_interleaved_write_frame(): Broken pipe

    5 October 2022, by Krishnakumar

    I am trying to stream video live using ffmpeg, Input is from a UDP Source. Most of the time it works fine, but I could see the following log lines and ffmpeg stop's the conversion/feed push to the rtmp server. Few log lines below for reference. Is this issue related to network on reaching the destination or source or something that i need to change in the ffmpeg command?

  • What encoders/decoders/muxers/demuxers/parsers/filters do I need to enable in FFMpeg for converting an mp4 video to a gif?

    21 June 2020, by kostik

    I am building FFmpeg with custom options to reduce the final size of apk file on android. I want just convert a mp4 file to a gif.
Following is my options specified

    


     --disable-everything
 --enable-decoder=mpeg4,mpegvideo,aac,gif,h264
 --enable-parser=aac,mpeg4video,mpegaudio,mpegvideo,gif,h264
 --enable-demuxer=mpegvideo,aac,mov,gif,h264
 --enable-muxer=mp4,gif,mov,h264
 --enable-protocol=file
 --enable-encoder=mpeg4,mov,gif,h264
 --enable-filter=scale,fps,copy,palettegen,vflip,paletteuse,crop


    


    What other options do i need to add to successfully run this command?

    


    ffmpeg -y -i input.mp4 -vf "fps=15,scale=320:-1:flags=lanczos" -pix_fmt rgb24 output.gif


    


    or this command

    


    ffmpeg -y -i input.mp4 output.gif


    


    After I added module into Android Studio I run FFmpeg command.
Iam getting this error:

    I also tried to include FULL library and it that case everything worked as expected.

    


    Thanks for your help.
