[mov,mp4,m4a,3gp,3g2,mj2 @ 05c3e940] Auto-inserting h264_mp4toannexb bitstream filter
frame= 8194 fps=0.0 q=-1.0 Lsize= 2254kB time=46:35:51.68 bitrate= 0.1kbits/s speed=1.19e+006x
video:2157kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 4.486598%the result give me a video mp4 file with a long duration like 46:33:20 and it not work, and iam sure that both videos have same reslution.
what i tried is to use this command to convert the videoffmpeg -y -i No-fade_25fps.mp4 -r 25 -s 1280x720 -c:v libx264 -b:v 3M -strict -2 -movflags faststart destination.mp4
and when i concate them again it worked and give me result mp4 file which have a right duration and worked fine but without a sound, because the first video file i use is muted no sound in it and second one contains a sound.
my question is how to concate those videos togther without this problem also what make the video have the problem of this long duration and when i convert them using the command line it worked ?

Fast Video Compression on Android

I am trying to crop rectangular video into a square one using FFMPEG. The video conversion take too much time.
For a video of 30 secs, it takes around 60-70secs to convert
FFMPEG Command
String commandStr =" -i "+videoPath+" -vcodec libx264 -b:v 880k -vf crop=" + videoSize.height + ":"+ videoSize.height + ":" + cropStart +":0 -preset ultrafast -strict -2 " +compressedVideoPath;

orangepi zero 2w, ubuntu, using a usb webcam ffmpeg to record videos, low FPS [closed]
28 janvier, par Qingfu ShiI use a OrpangePi zero 2w, USB HIK 2K Cam, to record videos.
Ubuntu, ffmpeg installed,
the cmd


ffmpeg -f v4l2 -video_size 1920x1080 -r 25 -input_format mjpeg -i /dev/video1 -vf "transpose=1" -c:v libx264 -preset fast -crf 23 output.mp4



I want the fps to be at least 25, so it looks smooth, but I only got about 4.7 fps.
