  • 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

  • Get video duration of file hosted on Amazon S3

    26 octobre 2016, par Michi

    I’m starting a portal which distributes videos. The idea is to upload the videos to Amazon S3 and gather the necessary data using PHP from my server. So far everything works fine... the only thing I could not manage to get is the duration of the video :-( Could anybody give me a hint on how to accomplish it ?

    Thanks,
    Miguel

    UPDATE :

    I finally opted to do it using FFmpeg. I have already installed FFmpeg on the server and I’m now trying to execute the command in the shell prior to execute it with PHP. I’m passing it the URL from Amazon (I tried both the cloudfront URL and the S3 URL) but it says that there is not such a directory or file. I’ve seen examples on the web using external files so I expected it to work.

    The command I’m using is

    ffmpeg -i https://s3-eu-west-1.amazonaws.com/path/to/file.m4v

    Is there something I need to configure in order to use external URLs ?

  • 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.
