FFmpeg extract frames from video
21 mai 2018, par KUTGI am currently using FFmpeg in Android with this lib. I am trying to extract 1 frame each second from a video. My current command is :
final String cmd[] = {"-i" + videoPath + "-vf fps=1" + mediaStorageDir.getAbsolutePath() + "a.png"};
Now i understand if this code were right the image would keep being overlapped because every image is called a.png. This is not the problem right now this code was for testing but I cant even get the command to work.
this is the error
Error splitting the argument list : Option not found
Any help is much appreciated. P.S i used this documentation to find the command

Extract all video frames as images with FFMPEG
14 janvier 2016, par user780756I am trying to convert a MP4 video file into a series of jpg images (out-1.jpg, out-2.jpg etc.) using FFMPEG with,
mkdir frames
ffmpeg -i "%1" -r 1 frames/out-%03d.jpgHowever I keep getting errors like,
[image2 @ 00000037f5a811a0] Could not open file :
frames/out-C :\Applications\FFMPEG\toGIF.bat3d.jpg
av_interleaved_write_frame() : Input/output error frame= 1 fps=0.0
q=5.9 Lsize=N/A time=00:00:01.00 bitrate=N/A video:63kB audio:0kB
subtitle:0kB other streams:0kB global headers:0kB muxing overhead :
unknown Conversion failed !If I take out the %03d part, the conversion works but it only outputs the first frame and the program stops with error.
How can I correctly extract all the frames of the video with FFMPEG ?
