  • rtmpproto : Validate the embedded flv packet size before copying

    3 octobre 2013, par Martin Storsjö
    rtmpproto : Validate the embedded flv packet size before copying

    This wasn’t an issue prior to 58404738, when the whole RTMP packet
    
was copied at once and the length of the individual embedded flv
    
packets only were validated by the flv demuxer.
    

    Prior to this patch, this could lead to reads and writes out of bound.

  • Extract specific frames of youtube video without downloading video

    22 janvier 2023, par Kashish Arora

    I need to extract specific frames of an online video to work on an algorithm but I don't want to download the whole video because that would make it highly inefficient.

    &#xA;

    For starters, I tried working with youtube videos. I can download whole of the video using youtube-dl in this way :

    &#xA;

    ydl_opts = {&#x27;outtmpl&#x27;: r&#x27;OUTPUT_DIRECTORY_HERE&#x27;,}&#xA;with youtube_dl.YoutubeDL(ydl_opts) as ydl:&#xA;    ydl.download([url])&#xA;

    &#xA;

    And then I can capture individual frames.

    &#xA;

    I need to avoid downloading the whole video. After some research, I have found that ffmpeg might help me do this. I found no way to download just the frames so if this is not possible, the second option is that I can download specific portions of the video. One such example in linux is here but I couldn't find any solution for python.

    &#xA;

    What is a good way to download just the frames, or portions of videos (in python) without downloading the entire thing ?

  • FFMPEG - speed up/slow down video, add jitter etc

    27 septembre 2019, par Darrell

    I’m trying to put together a Windows script that will process short videos in a folder.
    The videos will be shot at a high frame rate 60+ fps and be about 4-5 secs long.

    Basically I am looking to make various style clips, using fast/slow effects, back and forth etc.
    So, the script might process a video, make it start normal speed, then slow motion. Next video might be normal speed, slomo, normal speed slomo. Next video might be forwards,back, forwards back, slomo.

    See example : (this is a compliation, I’m looking at processing individual videos in a folder.)

    I’m guessing there is no way to do this, other than splitting a clip using FFMPEG, processing the bits, then merging back together ? I can’t seem to find a way to do it as one clip.
