How to optimize video to animated GIF conversion using PHP + shell commands
15 mars 2012, par user1070798I have a web application that converts any video into an animated GIF. The app runs in PHP and the following steps are executed through php's shell_exec :
- Scale video to smaller dimensions, if they are large (ffmpeg -i $in -s 200x150 -an $out)
- Use ffmpeg to extract 1 jpeg every x seconds (ffmpeg -i $in -ss $ss -vframes 1 $out)
-
Convert jpegs to animated GIF using imagick (convert -delay $delay -loop 0 $dir/* $out)
aside - the reason I don't use the ffmpeg gif89a output is because the quality sucks.
I want to be able to except any major image format, but the most common will probably be .flv (flash) and .avi/.mpg.
My application runs fine, but I am a perfectionist and it needs to be faster for scalability.
My web server has 16 cores and I would like to utilize them as much as possible, but .flv multi-threading appears to not be supported by ffmpeg, while .avi and some others are supported. Also, ffmpeg doesn't support multi-threading when outputting to jpegs.
Does anyone know of any other programs that support multi-threading for .flv and others ? Are there any more efficient methods to create an animated GIF from video, while maintaining relatively decent quality (aka not the 100-color palette that ffmpeg supports) ?
Also, if anyone knows which codecs might perform best for stages 1 and 2, particularly with flv, I'd love to know. I've done hours of testing, but there are just so many options I haven't come to any solid conclusions.
***Update : My online app is working well so far animated gif generator. I would still love to make it faster though, so if anyone has run into similar circumstances... let me know !

Chroma key software (script)
26 janvier 2012, par Noda CajuI have thousands of small videos in HDTV quality. All with green chroma key.
I need to change green colour for a static image (company logos).There are several softwares that can change chroma key, but they are only one by one file.
This will take years to be completed.Is there a software (script) that I can make this automatic ?

Samples RSS And Flashback Samples
22 décembre 2011, par Multimedia Mike — Game Hacking, PythonI made good on my claim that I would create an RSS feed for the samples repository.
Here is the link to the samples RSS feed [ http://samples.mplayerhq.hu/samples-rss.xml ]. Also, here is the Python source code I threw together for the task.
I just want to check : I’m not the only person who still relies on RSS these days, right ? The tech press has been cheerfully proclaiming its demise for some time now. But then, they have been proclaiming the same for Adobe Flash as well.
I’m no expert in RSS. If you have any suggestions for how to improve the features presented in the feed, please let me know. And, of course, keep the samples coming. This script should help provide more visibility for a broader audience.
Mario and Flashback Samples
Thanks to LuigiBlood who sent in some samples that allowed me to test out my new script for automatically syncing the repositories and updating the samples RSS feed. First, there are CPC multimedia files from the Japanese 3DO port of Flashback : The Quest for Identity. Then, there is an Interplay MVE file on the CD version of Mario Teaches Typing in which the video doesn’t decode correctly.LuigiBlood also sent in another file from the latter game. It’s big and has the extension .AV. It could be a multimedia file as it appears to have a palette and PCM audio inside. But there’s no header and I’m a bit unsure about how to catalog it.
