# openjpegenc

openjpegenc encodes raw video stream.

## Example launch lines

     gst-launch-1.0 -v videotestsrc num-buffers=10 ! openjpegenc ! jpeg2000parse ! openjpegdec ! videoconvert ! autovideosink sync=false

Encode and decode whole frames.

     gst-launch-1.0 -v videotestsrc num-buffers=10 ! openjpegenc num-threads=8 num-stripes=8 ! jpeg2000parse ! openjpegdec max-threads=8 ! videoconvert ! autovideosink sync=fals

Encode and decode frame split with stripes.
