Enhancement: Using the program as thumbnailer for nautilus file manager #47

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
With a little modification, this program could directly be used as
thumbnailer for nautilus (wich I would prefer over totem-video-thumbnailer,
the current default), without any intermediate script.

However, nautilus does not specify an extension for the output file and
ffmpegthumbnailer does neither provide the means of specifying the format
at the command line nor can chose it automatically. 

What steps will reproduce the problem?
1. Call the program with an output filename that does not provide an extension.

What is the expected output? What do you see instead?
Expected result: A thumbnail, with the type chosen automatically or
according to a format specified as parameter.
Actual result: Error: basic_string::substr

What version of the product are you using? On what operating system?
ffmpefthumbnailer version: 1.5.4
OS: Linux, Ubuntu Karmic, 32bit.

Please provide any additional information below:
It might furthermore be helpful, if the name format of the input/output
parameter could be specified (URI vs. pure file name).

So you want an option to specify the type of the output image?

This can be done. I'll try to find some spare time.

I just committed a change to subversion

It adds a -c command line switch that specifies the type of the image (jpeg or 
png)

e.g:
ffmpegthumbnailer -i input.avi -o output -c png

I think this is what you need.

I'm running Ubuntu 9.10 ... any of you lads tried to embed this code in 
Nautilus?
Please tell me it's manageable!

I've tried that, but I don't get any thumbnails. ffmpegthumbnailer version 
1.5.4 is 
installed on my system.

/usr/bin/ffmpegthumbnailer -s 128 -i %i -o %o -c png -f -t 10

Run this command manually replacing %i and %o with valid paths and see what 
happens
