Questions tagged [mencoder]

MEncoder is a free command line video decoding, encoding and filtering tool released under the GNU General Public License. It is a close sibling to MPlayer and can convert all the formats that MPlayer understands into a variety of compressed and uncompressed formats using different codecs.

mencoder (MPlayer’s Movie Encoder) is a simple movie encoder, designed to encode MPlayer-playable movies (see above) to other MPlayer-playable formats (see below). It encodes to MPEG-4 (DivX/Xvid), one of the libavcodec codecs and PCM/MP3/VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has stream copying abilities, a powerful filter system (crop, expand, flip, postprocess, rotate, scale, noise, RGB/YUV conversion) and more.

Dump last frame of video file using ffmpeg/mencoder/transcode et. al

I'd like to grab the last frame in a video (.mpg, .avi, whatever) and dump it into an image file (.jpg, .png, whatever). Toolchain is a modern Linux command-line, so things like mencoder, transcode, ffmpeg &c. Cheers, Bob.
