  • ffmpeg trying to remove the first few seconds of video

    21 octobre 2011, par zeroasterisk

    I'm trying to remove a few seconds off the front of a video stream (audio already excluded), and I'm getting strange results : I would think that for every second I increase -ss by, the resulting file would be a second shorter... that doesn't seem to be the case.

    original     ==> 01:04:52.84
    
-ss 19       ==> 01:04:42.84 (diff = 10) [command history shown below]
    
-ss 20       ==> 01:04:32.84 (diff = 20) [command history shown below]
    
-ss 21       ==> 01:04:32.84 (diff = 20)
    
-ss 25       ==> 01:04:32.84 (diff = 20)
    
-ss 0:0:25.0 ==> 01:04:32.84 (diff = 20)
    
-ss 0:0:25.5 ==> 01:04:32.84 (diff = 20) [command history shown below]

    Command : ffmpeg -ss # -i temp.mp4 -y -vcodec copy  temp_croppedFromStart.mp4

    Here's the command history for 19 & 20

    # ffmpeg -ss 19 -i temp.mp4 -y -vcodec copy  temp_croppedFromStart.mp4; ffmpeg -i temp.mp4 2>&1 | grep Duration; ffmpeg -i temp_croppedFromStart.mp4 2>&1 | grep Duration

  • Best way to load in a video and to grab images using c++

    17 octobre 2011, par Seb

    I am looking for a fast way to load in a video file and to create images from them at certain intervals ( every second, every minute, every hour, etc.).

    I tried using DirectShow, but it just ran too slow for me to start the video file and move to a certain location to get data and to save it out to an image. Even if I disabled the reference clock. Tried OpenCV, but it has trouble opening the AVI file unless I know the exact codec information. So if I know a way to get the codec information out from OpenCV I may give it another shot. I tried to use FFMPEG, but I don't have as much control over it as well as I would wish.

    Any advice would be greatly appreciated. This is being developed on a Windows box since it has to be hosted on a Windows box.

  • How to add text to a video with ffmpeg and python

    25 janvier 2013, par Jared Glass

    I've been trying to add text to an avi with ffmpeg and I can't seem to get it right.

    Please help :

ffmpeg = "C:\\ffmpeg_10_6_11.exe"
    
inVid = "C:\\test_in.avi"
    
outVid = "C:\\test_out.avi"
    

    
proc = subprocess.Popen(ffmpeg + " -i " + inVid + " -vf drawtext=fontfile='arial.ttf'|text='test' -y " + outVid , shell=True, stderr=subprocess.PIPE)
    
proc.wait()
