What you can do is simulate the image writing process by filtering with the fps filter, then using ffprobe to show the timestamps of the generated frames.

This class is a replacement for OpenCVs VideoCapture and can be used to read and decode video frames from a H.264 or MPEG-4 Part 2 encoded video stream/file.

This tool extracts frames, motion vectors, frame types and timestamps from H.264 and MPEG-4 Part 2 encoded videos. 2) d represents the day, but I need it to be the sequence of the current frame. It is intended only for the person to whom it is addressed. Two things here: 1) It seems that the H, M, and S represent the current system date and time that the screenshot was extracted, not the timestamp of the frame itself (I took the screenshot at 12:33:05).

But, what I need is that timestamp inside filename and I dont know how to get it. I want to be able to SEEK to that specific timestamp and extract the same frame FFMPEG has generated for me.īy using following command I am able to draw timestamp (pts) on each frame. Supports audio/video frames extraction (fast access to any frame by timestamp). image_00_00:00:00.1.jpg, where 00 is index generated by FFMPEG and 00:00:00.1 is timestamp from which frame was extracted.). audio/video processing library based on FFmpeg native libraries. What I mean by that is, I would like to include in file name a timestamp (e.g. Example command: ffmpeg -i input.mp4 -filter:v "fps=3" image_index_timestamp.jpgīut, I need to know which frame from original video FFMPEG has extracted. I would like to use FFMPEG in order to extract frames from this video at arbitrary FPS (e.g. int avseekframe(AVFormatContext s, int streamindex, int64t timestamp. I have a video file that lasts 9.3s and was recorded at FPS=10. ffmpeg: extract video frames from the video and save them as image files.
