FFMPGE Android, Merged Video ,Audio come before video on web browser
2 février 2017, par Himanshu Shekher JhaI 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; -
The most efficient way to generate mp4 video containing looped boomerang-alike video file ?
29 juillet 2019, par B. PalkaI’ve developed an Android app that allows user to create boomerang-alike mp4 video. This video consists of 10 still images being played back and forth quite fast. I know that such video (boomerang effect) can be easily looped from single video file while playing it, but I really need to create a mp4 video that would essentially contain already prepared boomerang video. The output video can be downloaded and played by user on any external player (over which obviously I don’t have any control).
For that purpose currently I create a video from images in a loop. The loop starts from 1st picture and goes to 10th picture with 0.25 sec delay between frames, then goes back from 10th to 1st including delay. And there is 5 of those loops, which essentialy means creating a single video from 5 * 10 * 2 = 100 images. I know it’s kinda ridiculous, so the time that it takes to prepare this video is riduculous as well (around 1:40 min).
What solution could you recommend assuming that the output video really has to consist of 5 loops back-and-forth ? I’ve thought about creating single loop video (20 pictures) and then create final output video by concatenating it 5 times. But could it be any good ? I’m trying to find an efficient yet understandable for a beginner Android programmer way.

Concatenating videos using concat demuxer in FFMPEG is finished but video is lost in second video ?
3 octobre 2019, par Gopinathan BUsed concat demuxer in FFMPEG code to concat videos :-
cmd = arrayOf("-y", "-f", "concat", "-safe", "0", "-i", textFile!!.path, "-c:v", "libx264", "-crf", "23", "-preset", "ultrafast", "-c:a", "copy", outputFile.path)
After concatenate finished, the video one played correctly has both audio & video but video two - video is missing has only audio. Output file has size & time duration including two videos.
The textFile contains :-
file '/path/to/file1'
file '/path/to/file2'Used
absolutePath
for two mp4 video files.Tryed this FFMPEG concat video finished but the video missing. But no solution to my problem.
Anything I am missing in the command.
