  • Server side video merging with FFmpeg through oline form

    1er août 2017, par San007

    I have a difficult problem and not enough knowledge to solve it, therefore I am hoping you guys can give me some advice or redirect me to a professional or professional software which can solve my problem.

    I want something fairly simple but I simply do not know how to begin. I Googled extensively but didnt find any related topics.

    What do I want ?
    I want an online form on my website where people can select different options, which are videos, for example
    Question 1
    1 (1.mp4) / 2 (2.mp4) / 3 (3.mp4)
    Question 2
    X (X.mp4) / Y (Y.mp4) / Z (Z.mp4)
    Question 3
    Email adres :
    Generate

    When the visitor clicks the generator button it should merge the video’s the customer has selected. e.g. 1 and X will result in one video file of 1.mp4 and X.mp4 merged. The system should then after succesfully merging the videos send a download link to the users e-mail adres and ideally delete the video from the server afterwards.

    I know I have not done a whole lot of research because my knowledge simply is not enough to create my own solution, but I hope you guys can send me in the right direction, I do not mind any commercial solution.

  • Livestream WebVTT with HLS

    10 novembre 2022, par kltye

    I've implemented an HLS service with ffmpeg (which pulls a live stream from nginx-rtmp). That all works fine, but now I'm wondering what kind of programming pattern I should be using to get live captioning to work.

    


    I'm planning on using ffmpeg to output the incoming mp4 stream to multiple WAV chunks (i.e., the same way HLS fMP4 parts are created), and then sending those chunks over to Azure Cognitive Services for speech-to-text recognition. My question is, what do I do when I receive the speech results ? Do I dump that vtt file into the same directory as my HLS chunks, and then serve that up using a single m3u8 file (with audio/video tracks along with the text track) ?

    


    Currently ffmpeg is updating the m3u8 playlist for HLS clients ; would it be possible for me to create the m3u8 playlist just for the vtt files, and serve that concurrently with the "regular" HLS playlist ? Also, time synchronization would seem to be difficult, because I'll be sending discrete WAV files over to Azure, so the vtt timestamps are going to be relative to the chunk I'm sending.

    


    Help ! I've done searches online, and I grasp the various issues, but I'm not sure how to plumb them all together.

    


  • FFMPEG : Get the Scene Change Detection value for all frame

    19 novembre 2016, par celacanto

    I’m trying to measure how much a movies is "fast" (more action in the screen and quick scene chances). I don’t want just a single value for the movie, but values along the movie to see how the action varies during it. After normalize the frame rate of the movies (10 fps), my idea is to compare each frame with the previous. I’m not only interest if the scene has changed, but also, if there was no cut, how much movement there is. Not only people/object movement but also, camera movement. In summary the paced (I think that the term) of the scenes.

    My idea was to use the scene function from ffmpeg as a metric. But looking at the document and examples online I’m thinking I can only use the value of the Scene Change Detection as a threshold to return frames informations, but I can’t get ffmpeg to return the value. Is that right ? There is any way I can make it return the value ?
