15 Oct 2010 mpgread The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file. Author: David Foti

Hi. I'm Jorge from Spain. I'm working in a academic proyect to finish my
Egineering degree. I'm trying to use mpgwrite and mpwread to design an
aplication about quality control in digital videos. My problem is with
mpgread. Whem I use mpgread I obtein one sequece of frames in a matlab
structure but in this structure frame 1 and frame 2 is the same frame than
frame 1 in the original video and I lost last frame. For example:

Compressed Video, frames: 1 2 3 4 5 6 7 8 9 10 Total number of frames: 10
Uncompressed Video, frames: 1 1 2 3 4 5 6 7 8 9 Total number of frames: 10

What can I do to resolve this problem? Thank's so
much in advance.
