create a video with tag on each jpeg
 
|
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 _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

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.

Am I missing something? 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? thanks Nicola > > Stefan > > > > > 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 > > > > > >> > >> 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 :) > >> > >>> > >>> thanks > >>> Nicola > >> > >> -- > >> Thiago > >> > >>> > >>> _______________________________________________ > >>> gstreamer-devel mailing list > >>> [hidden email] > >>> http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > >> > >> > >> _______________________________________________ > >> gstreamer-devel mailing list > >> [hidden email] > >> http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > > > > _______________________________________________ > > gstreamer-devel mailing list > > [hidden email] > > http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
