  • Audio output with video processing with opencv

    22 février 2012, par victor1234

    I am processing video with opencv, but at the same time I need to play audio and simply control it, like loud or current frame number.

    I think I should create a parallel process with ffmpeg, but I don't know how to do so. Can you explain what to do ?

    Or do you know another solution ?

  • ffmpeg images-to-video script anyone ?

    3 février 2014, par danja

    I'm wanting to take a bunch of images and make a video slideshow out of them. There'll be an app for that, right ? Yup, quite a few it seems. The problem is I want the slides synced to a piece of music, and all the apps I've seen only allow you to show each slide for a multiple of a whole second. I want them to show for multiples of 1.714285714 seconds to fit with 140 bpm.

    The tools I've seen generally seem to have ffmpeg under the hood, so presumably this kind of thing could be done with a script. But ffmpeg has sooo many options...I'm hoping someone will have something close.

    I'll have up to about 100 slides, the ones that have to show for 3.428571428 secs or whatever I guess I can simply show twice.

  • ffmpeg trying to remove the first few seconds of video

    21 octobre 2011, par zeroasterisk

    I'm trying to remove a few seconds off the front of a video stream (audio already excluded), and I'm getting strange results : I would think that for every second I increase -ss by, the resulting file would be a second shorter... that doesn't seem to be the case.
