I've written an article about some tricks you can do with ffmpeg, in today's article, I will show you another trick - compressing avi and mp4 video files with a simple command with a only a small loss in video quality.
If you dont have ffmpeg already installed, you can run this command to install it in Ubuntu and other Debian-based distros:
sudo apt-get install libav-tools
I've been trying to achieve a crossfade transition between 2 video clips using ffmpeg but have failed so far. I'm new to ffmpeg and am mostly relying on tweaking what I can find in the documentation and existing examples online.
We were randomly emailed by one Michal Sadowski, an entrepreneur from Poland. The video he sent us is a sort of MTV-esque homage to the swirl of experiences that might happen to a startup founder were they to compress their experience into a fast-paced music video, shot in the first person. It’s pretty creative, we’ll give him that.
I have a security question regarding the mime types.
I have a website on which users can upload videos. Prior to encoding with ffmpeg, I make a mime-type check to be sure the video file is really a video file and not a weird file or even an exec with a video file extension.
Nevertheless sometimes, mime-type aren't recognized, especially with mkv containers.
So what I wanted to do is compress files (using 7zip) and split a 600MB folder into 199MB parts, but sadly when I tried to do this task with archive manager it gave me an error, but I know that if I use terminal it will work.
My goal is to build ffmpeg static libraries so that i can use them with jni and call directly the functions defined in ffmpeg to encode series of images as h264 video stream and render it on screen using GLSurfaceVIew in android 2.3.6.
Using https://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html i came to know that by having the required .so files and headers i can do that.
