The barcode encoder generates barcodes as PNG files, than converts them to YUV files,
then stitches these into one YUV video file and finaly overlays this video over the
base video to produce a YUV video of the base with encoded barcodes in the upper part
of the video.
The decoder gets a YUV video with overlaid barcodes and first splits it into PNG files,
than decodes every file, and finally generates a stats file.
The encoder and decoder use Zxing and its Java command-line tools for the encoding and
decoding. They also use ffmpeg for the conversion between PNG and YUV and vice versa.

The tools could be used from trunk as:
./tools/barcode_tools/barcode_encoder.py --barcode_height=32 --base_frame_width=352
--base_frame_height=288 --base_yuv=<path_nad_name_to_base_file>
--output_yuv=<path_nad_name_to_output_file>
./tools/barcode_tools/barcode_decoder.py --yuv_file=<path_and_name_to_yuv_file>
--yuv_frame_width=352 --yuv=frame_height=288 --barcode_height=32
--stats_file=<path_and_name_of_stats_file>
By default the width of the barcodes is the same as the width of the base YUV frames.
This could be changes with the command-line option --barcode_width
