• FFMPEG commands in JavaScript

  21 juillet 2022, par Vladyslav Semeniuk

  Is it possible to use command like : ffmpeg -i video_1920.mp4 -vf scale=640:360 video_640.mp4 -hide_banner to reduce the resolution of a video in the pure JavaScript. For example I got a dropdown menu in which I have < a > tag, so I want to do a video quality selection by clicking on that menu hyperlink with JS. How to implement that properly, please help.

• Does anyone find this useful ? - Compiling FFMPEG on Windows with Cywin and NDK r5 [closed]

  5 avril 2017, par protectedmember

  Does anyone find this information useful in anyway ?

  I’ve been trying to compile this thing for a while now and I know of the numerous posts floating around the internet offering help. I have read and tried most of the suggestions and wanted to colate my success into this single post for others to benefit from.

  Since I don’t have a blog, I thought it wouldn’t hurt to post on here instead.

  I have managed to compile FFMPEG 0.10.3 (Freedom) on Windows 7 (32 bit) using NDK r5 and Cygwin. The steps :

  1 - Download/install Cygwin in the root of your C drive. I’m not going to give instructions on this, it’s simple enough and there are plenty of tutorials on this.

  2 - Download NDK r5 from here and extract to the root of your C drive.

  3 - Download FFMPEG 0.10.3 from here and extract to the root of your C drive.

  4 - Open the file ’configure’ in the root of the FFMPEG directory in a text editor.

  5 - Comment out lines 2073, 2074 and 2075.

  6 - Below 2075, add the following line :

  TMPDIR=c :/cygwin/tmp

  7 - Download this script (thankyou roman10) and place it inside your FFMPEG root directory. Rename the file to

  build_android.sh

  8 - Open the script in a text editor and edit line 17 to read

  c :/android-ndk-r5

  9 - Click start > run and type "bash" (without the speech marks) and press enter.

  10 - Type the following and press enter :

  cd /cygdrive/c/ffmpeg-0.10.3

  11 - Type the following and press enter :

  dos2unix build_andoird.sh

  12 - Type the following and press enter :

  ./build_android.sh

  13 - Sit back and wait... libffmpeg.so will soon appear in your "c :\ffmpeg-0.10.3\android\" directory (where is defined in the bottom of the script from roman10’s blog). The default architecture is armv7-a.

  The script from roman10’s blog will actually compile quite a large shared object (.so) file. The compiler flags can be adjusted to suit your needs in the script from roman10’s blog.

  I want to develop a cctv camera app and I don't know what steps I need to take.&#xA;i have the data below for connecting cctv camera :

  &#xA;&#xA;

  &#xA;
  • Ip address

  &#xA;

  • port ID

  &#xA;

  • user name

  &#xA;

  • password

  &#xA;

  &#xA;&#xA;

  i checked live555 and RTMPStreamPublisher demo from here, but i don't know where I should start. i also read that i should use the ffmpeg framework.

  &#xA;&#xA;

  What I want is an app similar to kView on itunes. This app is able to stream a cctv camera feed with the above configuration detials

  Does anyone know what direction I need to go in ? Is there a demo or open-source app that accomplishes this ?
