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

  5 octobre 2022, par 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 ?

• Bad output from ffmpeg running on raw video from Wear OS device

  17 juin 2020, par lcj

  I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.

  



  

  



  There is a lot of noise when I run this :

  



  ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4

  Any ideas ?

  


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

  21 juin 2020, par 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.
