External PHP with FFmpeg using readfile()

try <img src="thumbnail.php?&filename=video.flv&x=x.jpg" />

The %26name%3Dimage.jpg is just to fool the player into thinking that it is a jpg image (which it really is). You could probably end the image flashvar with just %26jpg which, unencoded is: image=thumbnail.php?filename=video.flv&jpg

thanks for the suggestions, however, it is still not working, not for the image nor for the actual file. I'm using SWFObject, so the exact code is thus:

and as for get_thumb.php, it basically takes in the objectid and spits out a "thumbnail" version. In the first case, the imgonly flag tells the script simply to get a image, while the second one will output an mp3 file that DOES EXIST (I've checked many times)

the file outputs only one HTTP header, the content-type. Should I use other headers, or no headers, or should I output the file in certain sized blocks or something? I've been trying for a while and always come back to this fundamental problem. And I'm trying to release the site real soon as well.

Thanks for reading.

Hey, thanks a lot, kLink. I just assumed that SWFObject would encode the strings for me. Guess not. I hope others can learn from my mistake.

Take it easy.

@Mike,

You're welcome. Good Luck! :)

I don't suppose you would be willing to share your script would you?

@Ashley,

What Script are you looking for? We share all of them.

I need the script to generate thumbnails from videos, will you upload it?

There a few lines of code (3) near the end of the script that output PNGs. If you want JPGs, comment out the PNG code, and uncomment the corresponding JPG code.

rachel is looking for the embedded flv in

can someone help

hello, i'm newbie. how the way to install ffmpeg in window? thx

@fredy,

Obtain ffmpeg from: http://sourceforge.net/projects/ffmpeg/

Unzip the package in the same directory as your video files.

Search these forums for the command lines for various uses of ffmpeg (transcoding, image extraction, muxing, streaming on demand).

The script klink provided is not working, can any one help me in this regard?

@Bilal,

Have you uncommented the various debug statements, one-at-a-time, working your way down from the top of the script, to see what is failing?

Call the script from your browser using the examples at the top of the script, until you find the point of failure.

Actually i dont have any file named ffmpeg-10141.exe,

the ffmpeg i downloaded have ffmpeg.exe,

i renamed this file to ffmpeg-10141.exe but still the script isnt working.

The filename doesn't matter, as long as it matches whatever you have, name it alakazamm if you want.

Did you try the debug steps that I posted above?

Line, 3 is where you input your video, the output.jpg is the output mpeg also called jpg image format which will be be grabbed. the output.ogm is the actual encoded video. ogm is just a open source video container like avi mkv etc. you can change it to whatever suits your needs.

Line 12, deals with the image grabbing which uses ffmpeg, not much to be said here.

Line 16, deals with Mencoder this basically is the encoding engine, here you can change bit-rate, video width and height and aspect ratio. and volume control.

Dependency packages and operating systems

1. Ubuntu 8.10 Desktop or Server version
2. Lamp server - php5 CLI everything that includes inside Lamp server
3. FFmpeg
4. Mencoder

thanks it.

isit possible to convert an swf to flv or avi or mpg....
if so how to,,!
could u please tell me how....

Thanks in advance,
Venkat.

Its Not possible Machi

I understand that videos with FFMPEG can be transcoded into images, but I am wondering how it's possible to grab/capture an image from an externally hosted video using an embed code.

I have no clue on how to get that going and am wondering if anyone knows.

I appreciate any help to get to this result.
