Processing time for adding an overlay to video using ffmpeg is too long in Android
23 septembre 2015, par AbhimanyuI am working on an app in which I am using android-ffmpeg-java library. I am using filter_complex to add a video overlay on static image but processing time it is taking is too long.
Can you please suggest any other library that could help me or how can i improvise the current codepublic Clip createOverlayVideo (String backGroungImagePath,String fiveSecsGifVideoPath , String outputPath, int x,int y,int bgwidth,int bgHeight,ShellCallback sc) throws Exception

FFMPEG Conversion from GIF to video with audio, take too long
5 novembre 2020, par Mouaad Abdelghafour AITALII'm trying to convert a GIF file into 720p video and merge it with audio, the code below works fine, but it takes a long time to finish the process (depends on the audio length) :


//Converting from GIF to video is fast!

public static String makeVideo(String inputGifPath, String outputPath, int width, int height) {
 return "-y -i " + inputGifPath + " -movflags faststart -pix_fmt yuv420p -vf crop=" + width + ":" + height + ":0:40,scale=1280:720,setsar=1 " + outputPath;
 }



//Merging video with audio takes a lot of time!

public static String addAudio(String audioNoSpace, String inputVideoPath, String outputVideoPath) {
 return "-stream_loop -1 -i " + inputVideoPath + " -i " + audioNoSpace + " -shortest -map 0:v:0 -map 1:a:0 -y " + outputVideoPath;
}


FFMPEG commands :


-y -i file.gif -movflags faststart -pix_fmt yuv420p -vf crop=540:250:0:40,scale=1280:720,setsar=1 video.mp4

-stream_loop -1 -i video.mp4 -i audio.wav -shortest -map 0:v:0 -map 1:a:0 -y final_video.mp4
