  • Opencv Videocapture fails to read http url videos

    16 mars 2019, par Purav Zumkhawala

    I want to read HTTP URL videos in my Ubuntu system without downloading them. I can do this in windows OS but when I try to run the same code in Ubuntu using the same opencv VideoCapture method it fails to get any frames.

    Why is this so ?

    I have used same opencv version in both Ubuntu and Windows, can anyone guide me towards a workaround, a tutorial using which I can compile opencv and stream url videos or any other library that supports this functionality in Ubuntu ?

    I have tried almost everything but with no productive result which has led me to finally ask this as a question.

  • FFMPEG-PHP Code example to trim MP3 file

    15 décembre 2012, par revive

    I've searched here and online,. and have not found clear PHP examples for taking a single MP3 file, and trimming it to a smaller file (removing both beginning and end portions and retaining only the content between a specified start time and end time)..

    What I'm trying to do is pass the start time, end time and mp3 file name to a PHP script, that will then use FFMPEG-PHP to effectively trim or concat that orig file.. without re-encoding it (and retaining all the orig. file metadata, etc.)

    If you provide an example of how to process an MP3 file like this, within one PHP file, it will help a lot ! I'm trying my best to help out our church, and simply don't know FFMPEG-PHP enough to sort this out solo.. :)

    Thanks !!
