7.7. Encoding from multiple input image files (JPEGs,PNGs or TGAs)

MEncoder is capable of creating movies from one or more JPEG, PNG or TGA files. With simple framecopy it can create MJPEG (Motion JPEG), MPNG (Motion PNG) or MTGA (Motion TGA) files.

Explanation of the process:

  1. MEncoder decodes the input image(s) with libjpeg (when decoding PNGs, it will use libpng).

  2. MEncoder then feeds the decoded image to the chosen video compressor (DivX4, Xvid, ffmpeg msmpeg4, etc.).

Examples.═ The explanation of the -mf option can be found below in the man page.

Creating a DivX4 file from all the JPEG files in the current dir:

mencoder -mf on:w=800:h=600:fps=25 -ovc divx4 -o output.avi \*.jpg

Creating a DivX4 file from some JPEG files in the current dir:

mencoder -mf on:w=800:h=600:fps=25 -ovc divx4 -o output.avi frame001.jpg,frame002.jpg 

Creating a Motion JPEG (MJPEG) file from all the JPEG files in the current dir:

mencoder -mf on:w=800:h=600:fps=25 -ovc copy -o output.avi \*.jpg

Creating an uncompressed file from all the PNG files in the current dir:

mencoder -mf on:w=800:h=600:fps=25:type=png -ovc raw -o output.avi \*.png

Замечание

Width must be integer multiple of 4, it's a limitation of the RAW RGB AVI format.

Creating a Motion PNG (MPNG) file from all the PNG files in the current dir:

mencoder -mf on:w=800:h=600:fps=25:type=png -ovc copy -o output.avi \*.png

Creating a Motion TGA (MTGA) file from all the TGA files in the current dir:

mencoder -mf on:w=800:h=600:fps=25:type=tga -ovc copy -o output.avi \*.tga
