  • How to capture multiple screenshot from youtube video using ffmpeg with specific seek time

    9 août 2017, par Md. Mehedi Hasan

    I’m using ffmpeg to take screenshot from youtube video. I want to seek multiple timeline. I’ve used the following command to capture 1 screenshot by seek command :
    ffmpeg -ss 00:02:10 -i "youtube-stream-url" -frames:v 1 out1.jpg

    How I can take multiple screenshot via multiple seek time. I’ve searched for the solution but no success.

    I’ve used the following command to take multiple screenshot as follows :
    ffmpeg -noaccurate_seek -ss 00:01:10 -i "youtube-stream-url" -map 0:v:0 -vframes 1 -f mpeg "thumb/output_01.jpg" -ss 00:02:10 -i "youtube-stream-url" -map 1:v:0 -vframes 1 -f mpeg "thumb/output_02.jpg"

    Is there any way to generate screenshots from same input via seek command ? How to make it more faster ? How to skip multiple input(-i param) ? I’ve also tried with other commands but those are more slower. Can anyone help me ?

  • How to seek mp4 file via Moov information [on hold]

    18 août 2017, par lucemia

    I am trying to write a python package which able to download part of mp4 file by specify time range.

    By this article, it mentioned

    MP4 files consist of chunks of data called atoms. There are atoms to store things like subtitles or chapters, as well as obvious things like the video and audio data. Meta data about where the video and audio atoms are, as well as information about how to play the video like the dimensions and frames per second, is all stored in a special atom called the moov atom. You can think of the moov atom as a kind of table of contents for the MP4 file.

    https://rigor.com/blog/2016/01/optimizing-mp4-video-for-fast-streaming

    I was able to extract the mooc info via some package :

    https://github.com/use-sparingly/pymp4parse/blob/master/pymp4parse.py

    Using chunks of MP4 file for thumbnails

    However, the details about how to compute the mapping between bytes range and time range is missing. Is there any document, or package can help me do so ?
