• Conversion does not end using ffmpeg on Android device

  3 février 2016, par Belhaver

  I am trying to make an application with usage of ffmpeg-android-java https://github.com/WritingMinds/ffmpeg-android-java and i have a problem. File conversion just does not end.

  Here is code which i am using :

  try {
  
      // code...
  
          String commandStr = "-y -i /storage/emulated/0/input.mp4 -strict experimental -s " + fileWidth + "x" + fileHeight + " -vcodec libx264 -r 30 /storage/emulated/0/output.mp4";
  
  
  
          ffmpeg.execute(commandStr, new ExecuteBinaryResponseHandler() {
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("FFMPEG success", "");
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
  
  
                  Log.d("FFMPEG failure: ", message);
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.d("FFMPEG process: ", message);
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
                  Log.d("FFMPEG done", "");
  
              }
  
          });
  
      } catch (Throwable e) {
  
          e.printStackTrace();
  
      }

  Here is the output process :

• Ffmpeg avs to avi lossless conversion

  21 février 2016, par Piotr

  How to convert avs (Avisynth file) to avi without loss of quality ?

  Firstly, I’m changing avs to 264 :

  ffmpeg -i "Source.avs" -c:v libx264 -preset veryslow -crf 24 "Output.264"

  Secondly, I’m trying to convert 264 to avi :

  ffmpeg -i "input.264" "output.avi"

  Final avi should have almost 200MB, but has only 2MB. 264 file has almost 150MB, so it should be good. I think that I should use some codec in second command, but I don’t know which. I’m trying to change this for a few days, but without effect.

  Or maybe there is a way to lossless conversion without 264, only avs to avi ?

  Thank you for your help.

  Edit :

  Thank you for answers. Unfortunatelly, both methods fail.
  First gives me a video, which is blurry and I can’t see anything on it.

• how to build ffmpeg with burn text on hls output while maintaining the aspect ratio

  26 février 2016, par Aameer

  My objective is to burn a text(watermark) at a particular time range on the outputed hls video, I also have to change just the height and maintain the aspect ratio which I am able to do but the burning in text part is not working. First the ffmpeg I used is for 14.04 ubuntu, details are here. I don’t think this build supports subtitle (docs) filter which I could have used for my purpose as described here. when i enter ffmpeg into the terminal this is the output

  and got an error

  then I tried this

  (ffmpeg)aameer@falcon:~/Documents/projects/ffmpeg$ ffmpeg -threads 4 -i "input_sintel_trailer_720p.mp4" -profile:v baseline -level 4.0 -vf "scale='trunc(360*a/2)*2:360', drawtext:drawtext"  -start_number 0 -hls_time 10 -hls_list_size 0 -f hls videos/4444/index_4444_360_.m3u8

  based on an answer here and got this error

  [AVFilterGraph @ 0x2695c20] No such filter: 'drawtext:drawtext'
  
  Error opening filters!

  I tried a static build too which i got from here but still couldn’t make it work. with this static build i tried :

  but got an error

  Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

  Any help in this regard would be appreciated. I don’t have much experience with compiling , otherwise would have done with support for libass as mentioned in the documentation here
