• How to record custom videos in Android [on hold]

  27 novembre 2013, par Chirry

  Context :

  Right now I have an App which takes the video from the camera and put some custome bitmaps on the same SurfaceView.

  Question :

  What I'd like is to record a video with the camera view and the custom Bitmaps on it.

  I have heard about AndroidFFmpeg third party codec to record videos, but I don't know how, I mean, is there any function on the AndroidFFmpeg to record videos in Android ?

  Hope you can help me with one this as there is not much information on the internet !

• PHP ffmpeg fetch metadata missing title, author, comment, artist

  19 avril 2012, par chrismacp

  I've been trying to fetch remote mp3 (and other format) meta data using the php5-ffmpeg extension.

  It is working although I am always missing the title, author, comment, artist details.

  I've been scouring the web for an answer but not found any solution.

  I did find this patch http://cvs.pld-linux.org/cgi-bin/viewvc.cgi/cvs/packages/php-ffmpeg/tests-metadata-api.patch which I thought may solve the problem, but I've been unable to compile php-ffmpeg even without the patch so haven't been able to work out if it will fix the problem.

  It seems this extension was abandoned a couple of years ago so I'm not holding out much hope of getting this working.

  Does anyone have any ideas of how to get remote meta data from audio video files using other tools ?

  I am thinking of just parsing the output of ffmpeg itelf using the '-i' option as this does return the correct meta data. Just a bit wary of calling exec in PHP for security reasons.

• SOLVED - Compiling FFMPEG on Windows with Cywin and NDK r5

  19 mai 2012, par protectedmember

  This isn't a question - it's an answer for alll of you who have been facing the same problems as I have. 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 :

  ./build_android.sh

  12 - 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 hope this helps,

  P.
