  21 avril 2016, par Jay Parikh

  I am using this repository to build ffmpeg static library which includes x264,libpng and others, please
  visit this link https://github.com/writingminds/ffmpeg-android

  i am using windows 7 as host and ubuntu 15.10 (_64) as guest os using VMware Workstation 12
  and
  Android-ndk-r11b-linux-x86_64

  i do have Prebuilt libraries , but now i want it without PIE support

  i am getting this error in config.log in x264 folder while building
  through

  ./android_build.sh

  here is the log :

  ushare is my shared folder between windows and ubuntu

  I have spend almost a week ,trying to solve every error i get.
  these errors are like never ending , 1 solution give 10 more errors
  i have researched a LOT for this library

  thanks a lot in advance.

  Also i thought that x264 library might have poroblem ,so i tried to disable it
  but next library "libpng" also had Same log Error

  i think problem is in Input/output error (obviously)
  this line in log kind of confuses me (those /../../)

  /mnt/hgfs/uShare/ffmpeg-android/toolchain-android/bin/../lib/gcc/arm-linux-androideabi/4.9/../../../../arm-linux-androideabi/bin/ld : fatal error :

  its like two folder overlaping address...

  thanks a lot in advance.
  please don’t go harsh on me ,its my first time,all thanks to this thing...

• FFMPEG how to record aac codec audio same time with video ?

  13 décembre 2017, par Gomi Odabaşıoğlu

  I am trying to use FFMPEG console tools effectively. Now I can record video and audio same time but my issue audio is delaying. I use following code :

  C:\Users\gomid_000\Desktop\ffmpeg.exe -y -f dshow -i audio="Stereo Mix (Realtek High Definition Audio)" -f gdigrab -show_region 1 -framerate 60 -i desktop -map 0 -map 1 -c:v libx264 -preset ultrafast -pix_fmt yuv420p C:\Users\gomid_000\Desktop\out.mp4 -threads:1 4

  I want to use h264 - Intel quick sync codec for video and for the audio
  AAC codec My machine accepts it.

  I tried to use Intel QSV with following code, is that correct ? (scroll "-c:v h264_qsv" part of the code)

  C:\Users\gomid_000\Desktop\ffmpeg.exe -y -f dshow -i audio="Stereo Mix (Realtek High Definition Audio)" -f gdigrab -show_region 1 -framerate 60 -i desktop -map 0 -map 1 -c:v h264_qsv -pix_fmt yuv420p C:\Users\gomid_000\Desktop\out.mp4

  Still do not know How to use AAC to record audio and keeep video and audio matching times automaticly. It is not installed maybe (?) (I do not know how to tell this in English will try :"Person speaks but audio comes very near but delays a little bit when I try bandicam they just match each other without any delay this is not hardware related.")

• Interval option when downloading HLS format videos published on Internet sites using ffmpeg

  28 septembre 2021, par atsu8492

  I'm trying to download HLS format video as mp4 using ffmpeg.

  


  I don't want to bother the server side due to excessive requests, so I want to create an interval for ts file acquisition.

  


  When I actually run ffmpeg, I sometimes get an HTTP 429 error as shown below.

  


  In addition, it looked like there are no good options in ffmpeg.
