• Android : mp4 file plays when downloaded but when choosing "Video" player gets "Cannot play video"

  14 janvier 2014, par gview

  I've converted the video to an mp4 with ffmpeg using the h264 codec and AAC, and used the baseline profile.

  Videos are 540x360x250kbps

  I then ran qt-faststart on the file to move the atoms into the right order.

  I've stuck the file up on a wiki we use and created a link to it.

  My test phone is a Samsung Galaxy S3.

  When I browse to the page that has links to the mp4's on it, and I click on them, I get a popup window with 2 options : Internet and Video.

  If I download the videos using the "Internet" option, I can play them on the phone without issue.

  I've done other encodings with the main profile as well, and these also play fine. I thought that a powerful phone like the s3 would be able to handle the more advanced compression schemes available in h264, however I've also browsed the Android docs in regards to supported video formats, and it seems to state that only the "baseline" compression profile is supported.

  Regardless, what doesn't work is trying to use the "Video" option which I assume tries to stream the video.

  For the wiki in question, clicking on the link reveals that the content-type and content-length headers are being set :

  Content-Length  6175996
  
  Content-Type    video/mp4;charset=UTF-8

  Clicking on the link with a browser invokes a player (Quicktime in most cases) that can play the mp4's.

  Is there more to having the file HTTP streamable beyond making a link to it ? Why won't my Android 4 play these files ?

  UPDATE :
  I decided to make a quick HTML5 page using the video tag, and the videos do play on both my Galaxy S3 and the latest IOS.

• Android FFmpeg reports "file protocol not found"

  27 avril 2017, par Abdul Mateen

  I am trying to convert sequence images to video using ffmpeg command in android.
  I have build ffmpeg for android and put ffmpeg binary file in /data/local folder.
  I am running ffmpeg command using Runtime.getruntime.execute("mycommand") in Android.

  Stucture of mycommand is like this

  "/data/local/ffmpeg -r 40 qscale 2 -i /mnt/sdcard/images/img%d.jpg /mnt/sdcard/images/finalvideo.mp4" 

  mycommand contains the path of a folder where I placed all my sequence images. Running this command gives me error "protocol not found".

  Also I read that file protocol is default in ffmpeg documentation.

  How can I run such commands ?

  The Error I am getting after running simple command like ffmpeg -i /mnt/sdcard/vid.mp4

• Bambuser ffmpeg - "arm-linux-androideabi-gcc is unable to create an executable file."

  14 avril 2014, par Chaitanya Chandurkar

  I know this may be possible duplicate of some questions. but answers for those threads are not helping me.

  I am trying to compile ffmpeg library for android using Bambuser's ffmpeg.
  I downloaded Archive for client versions 1.3.7 to 1.6.0. from bambuser.

  I followed instruction given in REAME.
  While running ./build.sh i came across following error

  arm-linux-androideabi-gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from SVN.  If the latest version fails, report the problem to the
  
  ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solving the problem.

  Here are last few lines of config.log of ffmpeg

  mktemp is /bin/mktemp
  
  check_ld
  
  check_cc
  
  BEGIN /tmp/ffconf.qflVj27Q.c
  
      1   int main(void){ return 0; }
  
  END /tmp/ffconf.qflVj27Q.c
  
  arm-linux-androideabi-gcc --sysroot=/home/chaitanya/android/android-ndk-r5b/platforms/android-8/arch-arm -c -o /tmp/ffconf.gc6um0Ki.o /tmp/ffconf.qflVj27Q.c
  
  arm-linux-androideabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
  
  C compiler test failed.

  in tmp i do not find any relative folder or file as per config.log says "ffconf.qflVj27Q.c".

  I am doing this on
  1. Ubuntu 11.10
  2. OpenJDK 6
  3. android-ndk-r5b

  NOte :
  I only have API-10 Installed in eclipse. (if it matters :D)

  What could be the solution for this ?
