It can decode all media which MPlayer can decode and it supports all filters which MPlayer can use. Supported filters: cropping, scaling, vertical flipping, horizontal mirroring, expanding to create letterboxes, rotating, brightness/contrast, changing the aspect ratio, colorspace conversion, hue/saturation, color-specific gamma correction, filters for reducing the visibility of compression artifacts caused by MPEG compression (deblocking, deringing), automatic brightness/contrast enhancement (autolevel), sharpness/blur, denoising filters, several ways of deinterlacing, and reversing telecine.=== Rip / Encode a DVD ===You can use libavcodec to encode the video. Identify the source video. * Identify video framerate* Identify video frames/fields/pulldown/telecine* Encode constant bitrate (CBR), constant quantizer, and multipass* Crop black borders or letterboxing* select resolution and bitratesee: http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-dvd-mpeg4.html=== Rip from TV or Composite Source (V4L capture) ===Using mencoder for this is considered inefficient.
