Thiago Santos d49acb5588 jifmux: Detect EOI correctly
EOI are not always at the last 4 bytes. We need to search
the last 5 bytes to find the 0xFFD9 sequence as jpegenc seems
to round the buffer size to the next 4 multiple.

Thiago Santos ba15ad9387 jifmux: Put APP0 first always

Thiago Santos 407f615887 jifmux: Avoid recombining RGB jpegs
JFIF only allows YUV as colorspace, when we receive an RGB jpeg,
we should just push it forward without adding the JFIF marker.

Thiago Santos 20a8666388 Revert "jifmux: Merge xmp and tagsetter tags."
This reverts commit 4e5c412234.

jifmux shouldn't be able to handle jif and shouldn't expect
any xmp on its data. So, no need to handle them.

Thiago Santos 4e5c412234 jifmux: Merge xmp and tagsetter tags.
When the current file already has tags, they shouldn't be ignored,
parse them and merge with the tagsetter ones.

Thiago Santos a9e4c64efa jifmux: Reject buffers without caps
jifmux expects whole jpeg pictures in buffers, so it should
reject buffers without caps.

Check GstByteWriter returns to know when recombining the image
failed and log a warning.

Thiago Santos 0d637e4f09 jifmux: Avoid adding 2 xmp packets
jifmux was only appending a new xmp packet to the stream,
it should replace if there is already one.

Mark Nauwelaerts d68a4c1dcc jpegparse: improve buffer scanning
Specifically, when scanning for entropy data segment length and needing
more data, do not rescan from start next time around, but resume at
last position.

Stefan Kost caf2be2115 jpegparse: return offset+length from _get_image_length().

Tim-Philipp Müller a60d54c4e2 jpegparse: lower rank to NONE so it is not autoplugged for decoding
This element is too new and too untested to have it autoplugged.

Stefan Kost 6c6ea0b79b jpegformat: add a basic jifmuxer
The new element can chop and reassemble the markers. I implements the tagsetter
and for now can serialize some tags to jpeg comments.

Stefan Kost b9f8f5d281 jpegparse: improve parsing
Handle more app maker. Print app marker names to debug log. Remember last_marker
when parsing to avoid reparsing from the very begin.

Stefan Kost f3122f2b30 jpegparse: provide a getcaps function for src pad and improve setcaps
Previously jpegparse was failing in decodebin as the caps we were setting where not
setting all caps fields. We need the own getcaps function to report what we actualy
accept.

Stefan Kost e1dd998bd0 jpegformat: code cleanups
Move the jpeg marker defines to a header (to be used for jifmux). Rewrite some
comments. Use gst_element_class_set_details_simple(). Add more logging.
