create a video with tag on each jpeg

Mailing List SVR
Hi,

I would like to record a live video (mjpeg) and add a tag on each jpeg
image, I'm trying a pipeline like this:

gst-launch-0.10 -e -t http://192.168.2.17/moxa-cgi/mjpeg.cgi !
jpegparse ! taginject tags="comment=\"test image\"" ! jifmux ! avimux !
filesink location=/tmp/test.avi

this give the following output:

mpostazione della pipeline a PAUSED ...
La pipeline è in PREROLLING ...
TAG TROVATO    : trovato dall'elemento "taginject0".
        commento: test image
La pipeline è in PREROLLED ...
Impostazione della pipeline a PLAYING ...
New clock: GstSystemClock


and when I play the generated file only a tag is generated and it is on
avidemux and not on the jpeg images:

gst-launch-0.10 -t filesrc location=/tmp/test.avi ! avidemux ! jpegdec !
xvimagesink
Impostazione della pipeline a PAUSED ...
La pipeline è in PREROLLING ...
TAG TROVATO    : trovato dall'elemento "avidemux0".
     codec video: Motion JPEG
TAG TROVATO    : trovato dall'elemento "avidemux0".
        commento: test image
formato contenitore: AVI
La pipeline è in PREROLLED ...
Impostazione della pipeline a PLAYING ...

any hints?

thanks
Nicola

Here's some tips on debugging it:

Drop avimux from the recording pipeline and use multifilesink to save
each image to a different file, then check if the individual jpegs have
the tag.

Also, try adding jpegparse on the playback pipeline and check if it
finds those tags, not sure of the tag reading capabilities of jpegdec.

Good luck :)

with this pipeline:

gst-launch-0.10 -e -t http://... ! jpegparse ! taginject tags="comment=
\"test image\"" ! jifmux ! multifilesink location=%02d.jpg

each image has the tag, do you know a way to mux the image with the tag?

I tryed:

gst-launch multifilesrc location=%02d.jpg
caps="image/jpeg,framerate=5/1,width=352,height=288,pixel-aspect-ratio=1/1" ! videorate ! image/jpeg,framerate=5/1 ! avimux ! filesink location=test.avi

but after the muxing the tag is in the avi container and not in the
jpegs? Am I missing something?

Reading the docs:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-tags-write.html

"A nice extra feature in GStreamer tag support is that tags are
preserved in pipelines"

this doesn't seems true with the posted pipelines,

thanks
Nicola

Yes, as thiago said, add jpegparse in the playback pipleine. Otherwise you only
get the tags from the avi-container and those that jpegdec finds.

Thanks but also using jpegparse the result is the same:

gst-launch -t filesrc location=test.avi ! avidemux ! jpegparse !
jpegdec ! xvimagesink
Impostazione della pipeline a PAUSED ...
La pipeline è in PREROLLING ...
TAG TROVATO    : trovato dall'elemento "avidemux0".
     codec video: Motion JPEG
TAG TROVATO    : trovato dall'elemento "avidemux0".
formato contenitore: AVI
TAG TROVATO    : trovato dall'elemento "jpegparse0".
     codec video: Motion JPEG
formato contenitore: AVI
        commento: test image
La pipeline è in PREROLLED ...
Impostazione della pipeline a PLAYING ...
New clock: GstSystemClock

are you able to save jpeg frame and tag in a container?
