  • FFMPGE Android, Merged Video ,Audio come before video on web browser

    2 février 2017, par Himanshu Shekher Jha

    I am merging two video together, One Video is created from image, and other Video is recorded from Camera. Before Merging I used a code to change codec of both video in same format. Everything is working well, but when i try to play video on web browser, We got audio of recorded video before Recorded Video Start.

    FFMPge code to create video from image is

    "-loop 1 -i " + profileImagePath + " -i " + recordedAudioPath + " -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest " + profileVideoPath;

    FFMPge code to change codec of video

     " -s  640x360 -vcodec libx264 -acodec aac -strict -2 -pix_fmt yuv420p  -ac 1 -ar 16000 -r 13 -ab 32000 "

    FFMPge code to merge video

    String list = generateList(new String[]{ profileVideoCodecPath, recordedVideoCodecPath});
    

    
            String cmd = " -f concat -i " + list + " -c copy " + mergedVideoPath;

  • How to add intro image beginning of video with same video aspect ratio in ffmpeg ?

    10 juin 2021, par Manoj Kag

    I have one image and one video. I would like to add image as video just before actual video so i can stream video with intro frame for 5 seconds.

    


    I found one command and full fill my requirement but in that command image added at the end of the video and i need beginning of the video. Let me share command below :

    


    ffmpeg -i 1.mp4 -loop 1 -t 5 -i 2.jpg -f lavfi -t 5 -i anullsrc -filter_complex "[0]split[base][full];[base]trim=0:5,drawbox=t=fill[base];[1][base]scale2ref=iw:ih:force_original_aspect_ratio=decrease:flags=spline[2nd][base];[base][2nd]overlay='(W-w)/2':'(H-h)/2'[padded];[full][0:a][padded][2:a]concat=n=2:v=1:a=1[v][a]" -c:v libx264 -c:a aac -strict -2 -map "[v]" -map "[a]" output.mp4

    


    Image should be resize dynamically according to the video resolution.
Best solution will be appreciate from bottom of heart.

    


  • Smaller video file size while keeping the quality of video ?

    12 octobre 2016, par user3157841

    I am newbie for Video analysis,
    I am looking for a solution that can decrease (or losing not much) the size of video (bytes) but that does not also decrease the picture quality of video (resolution).

    I also research from FFMPEG lib, but I can not find out any solution ?
    Anyone can help me or give me suggestion for this problem ?
    Thank you so much
