wandenberg / nginx-video-thumbextractor-module Goto Github PK

The make error is:

/usr/bin/ld: cannot find -lMagickWand

I've compiled ImageMagick froum latest source on Debian Wheezy X86_64. Nginx and module are latest from git.
For workaround I use:
sed -i -e "s~-lMagickWand(-6.Q16)?-lMagickWand-6.Q16" ~/src/nginx-modules/nginx-video-thumbextractor-module/config

video_hash.h mentioned here https://github.com/wandenberg/nginx-video-thumbextractor-module/blob/master/include/ngx_http_video_thumbextractor_module.h#L7 couldn't be found while compiling.
I have ubuntu 11.10 x64 with ffmpeg, ImageMagick/MagickWand

I took a look at Youtube thumbs preview and could notice that they create a single image with frames concatenated, like the image below:

This leads to a more fluid seekbar navigation since the frames appear faster (just changing the visible window in css, in case the seekbar is made by DOM elements, for example). I'm wondering if it's possible to create this feature inside the module itself, what do you think?

does nginx-video-thumbextractor-module support on windows platform?

my config

Hi,

it is not handy to create modules that depends on latest source code of FFMPEG. This means that we have to compile manually FFMPEG first before this module can be used.

Is it possible to support Ubuntu LTS versions? That means using an older ffmpeg and containing libraries? I can not imagine that the code to extract thumbnails uses that exotic code. Now we have the following error:

Hello, I just ran into this:

cc1: warnings being treated as errors
In file included from ../nginx-video-thumbextractor-module/src/ngx_http_video_thumbextractor_module.c:28:

replacing line 268 with newer ffmpeg function should do the trick:

if (pFormatCtx != NULL) avformat_close_input(&pFormatCtx);

Is it possible to make this module compatible with FFMPEG5 ?

With nginx-1.7.10 I get the following error when running make:
