you can check a file like that with md5sum -c, it gives output like this:

Code:
 $ md5sum -c checksum.txt 2>/dev/null
a: OK
b: FAILED
c: FAILED open or read
d: OK

so you could handle it like this:

Code:
while ! md5sum -c checksum.txt > checklist
do
        awk -F: '!/OK$/ && $0=$1' checklist | while read FILENAME
        do
                echo "Need to download $FILENAME"
        done
done

gst-md5sum

GStreamer(1)						      General Commands Manual						      GStreamer(1)

NAME

       gst-md5sum - get an md5sum of a GStreamer pipeline through md5sink

SYNOPSIS

       gst-md5sum [OPTION...] PARTIAL-PIPELINE-DESCRIPTION

DESCRIPTION

       gst-md5sum generates MD5 checksums of the data generated by a GStreamer pipeline.

       In theory, running

	    gst-md5sum filesrc location=music.mp3

       should print out the same checksum as

	    md5sum music.mp3

       The  pipeline  should  be  incomplete,  that  is, a final sink element should be omitted, so that gst-md5sum can connect the pipeline to an
       md5sink element.

       See the man page for gst-launch or the GStreamer docuementation for more information on how to create a PARTIAL-PIPELINE-DESCRIPTION.

OPTIONS

       gst-md5sum accepts the following options:

       --help  Print help synopsis and available FLAGS

       -v      Output verbose information

       --gst-info-mask=FLAGS
	       GStreamer info flags to set (list with --help)

       --gst-debug-mask=FLAGS
	       GStreamer debugging flags to set (list with --help)

       --gst-mask=FLAGS
	       GStreamer info and debugging flags to set (list with --help)

       --gst-plugin-spew
	       GStreamer info flags to set Enable printout of errors while loading GStreamer plugins

       --gst-plugin-path=PATH
	       Add directories separated with ':' to the plugin search path
