  • Python get Audio/Video frames separately from video file

    3 juillet 2016, par AlvaroAV

    What i’m trying to do :

    Hi !

    I’m trying to store the Video and Audio information from a video file. I would like to store video frames and audio frames separately in different variables.

    My intention is to manage video/files and do some actions with the audio and video frame list, but to do what I’m plannign to do I need to store this audio/video frames separately. I’ve read a lot of questions in StackOverflow about python and audio/video managing.

    Most people recommend to use OpenCV or ffmpeg to manage videos. I saw some scripts using these libraries to get video(only video) frames, but none of them are getting audio, most of them are just getting video frames and save them as RGB images. I also check some scripts where people get audio frames from a mp3 file, but I’m not sure if you can do that in a video file

    Most important thing to me is to know the best way to manage video and audio separately. I’m not looking for people to do my code, just asking to point me in a good direction.

    One of the things I’m trying to do is to send this information via socket, but as I said I need the audio and video frames to be in separated variables (yes, i’m wondering about an stream app, but that’s not the only thing I’m trying to do)

    I know I should give more information, and maybe show some code, but I don’t have any concret code I tried some things, but I’ve never been capable to separate audio and video. I know that each format has his own encryption, and at the end I decided to use "mp4" as video format but I don’t know neither if this is the best format for what I’m trying to do.

    Resume :

    Is openCV the best way to manage video and audio separately ?

    Wich is the easiest way to separate video and audio frames ? Is it possible ?

    Wich is the best documentation I should read to learn about video/audio management ?

    I would like to do the things with my own code, and use in the less way possible openCV or other libraries.

    My "basic" idea is to get a "list" of audio and video frames, and then I would like to do some operations, but right now I can’t find the best way for me to manage a vide using python. I even wonder if could be possible to manage a video as raw data

    I need to know wich is the best library to manage videos using python, for me the best library, will be the one that allows me to manage the videos more "freely"

    I’ve already checked :

    I’ve read too many questions on this theme, the most recent are :

  • Combining background video, audio, text and image to create a new vertical 1080*1920p video using ffmpeg

    3 mars 2023, par Arya Anish

    How can I combine background video, text and image to create a new vertical 1080*1920p video using ffmpeg. The text is contained in a sentences.txt file and each sentence is seperated by a line. Each senetence should stay on the video for n seconds. (for eg. 2 seconds) I tried using ChatGPT but, I quit, I spent 2 hours debugging and I don't want to do so for another 10 hrs.

    


  • PHP FFmpeg, upload video and let user select start and end offsets to trim the video

    9 novembre 2015, par Kunal

    This is what I need to do :

    1. User goes to the HTML web app (works on desktop and mobile)
    2. Uploads a video (depending on phone recording and bitrate, could be 100mb)
    3. Use FFMPEG to trim the video to 15 seconds only.

    Now for the 3rd part we need to let the user select the start and end offsets for the trimming. Maybe extract scenes and let them select ?

    Please help. Thanks in advance.
