How to join two videos containing audio as well using Python ? [on hold]
5 janvier 2018, par Sarthak AgarwalI have to join two videos (contains audio as well). The second video has to be appended to the first after some adjustment (ie. some movement in XY axis, so that the second video appears to seamlessly/continuously join the first one). OpenCV is essentially a computer vision library, and does not support audio. I have to use python for that. How to go about it ? Please help me out here ? Thanks in advance.

ffmpeg how to make same streams for videos
30 septembre 2022, par bogdaryanThe documentation says that




All files must have the same streams (same codecs, same time base,
etc.)




I tried this, I thought it would help to make the same streams for all videos


ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -filter_complex "[0]setdar=16/9[a];[1]setdar=16/9[b];[2]setdar=16/9[c]; [a][b][c]concat=n=3:v=1:a=1" output.mp4



Is there any way to make all video the same streams to do then by the method with txt file ?


ffmpeg -f concat -safe 0 -i mylist.txt -c copy mergedVideo.mp4 



It would be very convenient, first do the conversion in one stream all the videos, then take their paths and combine. Just if I immediately do concat through the method with txt, some parts of the video just freezes the screen. I read, and they said to do same streams (same codecs, same time base, etc.)

Best way for stream videos on web [on hold]
13 février 2016, par AmirI am working on video-sharing website and looking for Appropriate way to stream videos because all users can send video in my site. I wonder which way is best to stream all videos like YouTube, compatible with all speed and all the qualities and can change quality . breathed apple hls finally arrived, but the only problem is that for the video to the must take into consideration multiple video files . ffmpeg seagment that the server takes up this much volume.
The second way that came to my mind is live transcoding. It does not change its quality by changing the speed of video, but this version was with JavaScript wrote such a thing. Speed and space as large as any video website YouTube will be more suitable, but when I thought this was the way all the server and does not work. Most importantly, when you upload a video to YouTube you see it say the process is completed so it means YouTube will not use this method. I think YouTube very easy to convert several formats witout seagment . change the quality generated script that was said !!
In your opinion, when is the most appropriate way ?!
Thankful
