  • How to create videos from images with php ?

    1er avril 2017, par motto

    Let’s say I have 10 images and I want to combine those images in a video like a slideshow.

    For example I want to show each image for 5 seconds and then continue with next image for another 5 seconds.

    If it’s possible, it will be perfect to include music and some descriptive text too.

    Is there a sample code for this may be with ffmpeg library ?

  • How can I know the error in command in an exec function ?

    23 novembre 2011, par shinod

    I am using a ffmpeg command to cut a video with exec function in php. But it is not creating a video file and doesn't show any errors. I used exec as below

    exec("ffmpeg -i input.flv -ss 00:00:30.0 -t 00:00:10.0 -acodec copy -vcodec copy -async 1 output.flv");

    Can I get any help to know what is the error happening here ?

    exec("ffmpeg -i input.flv -ss 00:00:30.0 -t 00:00:10.0 -acodec copy -vcodec copy -async 1 output.flv",$output);

    I tried it also. But I didn't get any error message in variable $output

  • Live Streaming WebM with Wowza Server

    2 décembre 2010, par noreply@blogger.com (John Luther)

    Guest blogger Charlie Good is CTO and co-founder of Wowza Media Systems

    As a company, we at Wowza move fast and like to tinker. When WebM was announced in May, we saw it as a promising new approach to HTML5 video and decided to do an experiment with live WebM streaming over http.

    Adding WebM VP8 video and Vorbis audio to the other encoding formats that our server supported was easy (we designed the Wowza server to be codec-agnostic). We then created a WebMfile and implemented WebM HTTP streaming.

    We originally created the demo as a proof-of-concept for the IBC show in September, 2010 but have made it available to watch on our web site.

    The file is streamed live (more precisely, "pseudo-live") over http using the Wowza server-side publishing API (PDF). The result is very impressive ; playback starts fast and the VP8 image quality is fantastic.

    You will need a WebM-enabled browser or VLC media player 1.1.5 to view the live stream.

    If you’re interested in keeping up with Wowza’s WebM progress, visit Wowza Labs or drop us a note at info@wowzamedia.com.
