• Videos which is only played by particular app, need help to save it

  19 septembre 2015, par Kumar

  There’s a app(i can’t disclose the app name) which plays video stored in memory card and videos have no extension, by viewing the file sizes im assuming that they are the videos + I also check changing the extension with mp4 flv 3gp etc but no success. I then decompiled the app and saw that app is using ffmpeg-jni to play the videos. Anybody can help me in this ? and yeah all videos have IGN in their meta tag.

  Thanks

• How can we play 2 videos side by side as per the resolution we provide to the output video and adjust the two input videos position

  1er décembre 2023, par Bhavya Nayak

  -> For playing two video side by side as per the output video resolution I provide :-

  


  

  1. I want output video of resolution 1280x720 so for this.

  


  


  a. First I have trimmed the two video using below command :-

  


  ffmpeg -i input_viedo.mp4 -ss 00:00:10 -t 00:00:20 -vf      "scale=1920:1080,pad=1920:1080:0:0:yellow" -c:v libx264 -c:a aac -strict -2 output_video_trimmed.mp4



  


  b. Now to I want to play both the trimmed video into one output video file as per the position I provide , so for this I have tried below command which is not giving the correct output :

  


  ffmpeg -i output_video_trimmed_1.mp4 -i output_trimmed_2.mp4 -filter_complex "[0:v]scale=634:360[pad1];[1:v]scale=640:360[pad2];[pad1]pad=1280:360:0:100[tl];[pad2]pad=1280:360:634.752:130.392[br];[tl][br]vstack,scale=1280:720[output]" -map "[output]" -c:v libx264 -preset ultrafast -crf 18 -c:a aac -b:a 1280x720 output_final_video.mp4


  


  

  • In above command I have provide the specific width,height,top,left of the input video I want ,

  


  


  But it is not giving me correct output.

  


  —> Output I am getting by running this command is attached below :-

  


  Output video Image I am getting by running above command

  


  Actual output I want

  


  —> The issue in above command is while adding top it is not working properly , like top is not affecting the video so I want the solution for that.

  


• Removed some unused declarations (per jslint), grouped private methods together, DOMContentLoaded event cleanup ; Better pre-init/unsupported warning messaging for play/createSound() calls made before init or if SM2 is otherwise unavailable (eg., failed to start) - no longer throws an error object, just console.warn()-style messaging.
