Description

Parses a JPEG stream into JPEG images. It looks for EOI boundaries to split a continuous stream into single-frame buffers. Also reads the image header searching for image properties such as width and height among others. Jpegparse can also extract metadata (e.g. xmp).

Example launch line

1	gst-launch -v souphttpsrc location=... ! jpegparse ! matroskamux ! filesink location=...

The above pipeline fetches a motion JPEG stream from an IP camera over HTTP and stores it in a matroska file.
