Extracting frames from mp4 clip using ffmpeg
Hi, I'm using ffmpeg to extract all frames contained in a 10 seconds mp4 file (avc/no audio), this is the syntax of the bat file (name: "extract-frames.bat"):
Code:
ffmpeg -i input.mp4 -r 1 output%05d.png pause Code:
[image2 @ 022fcce0] Could not open file : outputC:\Jan2014\01\extract-frames.bat5d.png av_interleaved_write_frame(): Input/output error I was following this example: http://www.alecjacobson.com/weblog/?p=2102 |

Found this with a quick Google search:
FFMPEG - Making an Image Sequence from a video Code:
ffmpeg -i "input.mov" -an -f image2 "output_%05d.jpg"

The problem is that %0 in batch always causes the same issue, even with that command line:
Code:
[image2 @ 024ad520] Could not open file : output_C:\Jan2014\01\extract-frames.bat5d.jpg av_interleaved_write_frame(): Input/output error Edit: tried with latest build from here but the problem is the same, probably %0 shouldn't be used. Last edited by Nozdrum; 10th February 2014 at 17:37. |

Try adding a "-start_number 0" parameter.
