Do you have practical experience working with video materials or video processing?

Yes, I have practical experience working with video materials and video processing on Android. I have used tools and libraries such as:

• MediaCodec and MediaExtractor for decoding and encoding videos.
• Camera2 API for capturing video from the camera.
• OpenGL ES for applying effects and processing video in real-time.
• Libraries like FFmpeg (via JNI) for more complex processing, conversion, and compression of videos.

For example, I developed an application that captured video from the camera, applied filters, and saved the result to a file. I also worked with streaming video and real-time frame processing.
