  • How do I use ffmpeg with live streaming from an IP camera [closed]

    28 février 2013, par Murali Hariharan

    My question is very basic because I am a newbie to all these
    technologies.

    I have an IP camera connected to my internal network.

    http://192.168.1.20/videostream.cgi?user=admin&pwd=

    ...gives a live streaming view in Firefox or Internet Explorer.

    Now I want to record the live stream into a video.

    The parameters to be supplied are begin_time, end_time, format of video etc.

    How do I accomplish this ?

    I appreciate any guidance.

  • Retrieving metadata from x264 ?

    29 février 2012, par Blender

    I am trying to exctract the meta data from x264-encoded video files. First priority is to map the IDR-frames structure. The work seams to be harder than expected and I am trying to find command line applications that I can control from my code.

    Mp4box has an option "-dump-xml" or similar but I can't figure out how it works. Not much help available on the net on this option.

    Anyone who can give me a hint on this or any other alternative ?

    Thank you.

  • FFMPEG wont keep the frame rate and duration

    28 avril 2018, par macprodukshunz

    I have a .mov video that is 53.15 fps, I need to convert it with the same duration and frame rate to a mp4. When I do it it gives me a 60 fps mp4. How do I tell it to keep the same framerate ?
    I tried :

    ffmpeg -i input.mov -r 53.15 output.mp4

    That works with framerate but the duration changes and the output looses one second. I want the video to have the exact same basic attributes after conversion.

    Im using the Terminal on macOS Sierra, if that matters.
