ffmpeg images-to-video script anyone ?
3 février 2014, par danjaI'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 zeroasteriskI'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.

Get video duration of file hosted on Amazon S3
26 octobre 2016, par MichiI’m starting a portal which distributes videos. The idea is to upload the videos to Amazon S3 and gather the necessary data using PHP from my server. So far everything works fine... the only thing I could not manage to get is the duration of the video :-( Could anybody give me a hint on how to accomplish it ?
Thanks,
MiguelUPDATE :
I finally opted to do it using FFmpeg. I have already installed FFmpeg on the server and I’m now trying to execute the command in the shell prior to execute it with PHP. I’m passing it the URL from Amazon (I tried both the cloudfront URL and the S3 URL) but it says that there is not such a directory or file. I’ve seen examples on the web using external files so I expected it to work.
The command I’m using is
ffmpeg -i https://s3-eu-west-1.amazonaws.com/path/to/file.m4v
Is there something I need to configure in order to use external URLs ?
