Shmsrc doesn't work

[sofian]

I tried running the new shmsrc bin from https://github.com/vliaskov/libremapping (branch: feature/shmsrcbin-rebase-oct2014)

In order to perform the test I first run: $ gst-launch-1.0 uridecodebin uri=file:///home/tats/Documents/workspace/mapmap/DESTRUCT.mov ! queue ! videoconvert ! video/x-raw, format="RGBA" ! gdppay ! shmsink socket-path=/tmp/sock shm-size=100000000 Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Redistribute latency... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock

Then I run mapmap and try to add a new media file at /tmp/sock:

$ ./mapmap Using GStreamer version 1 . 2 . 4 Video support: yes Listening osc.udp://localhost:915912800 Could not add OSC handler Opening movie: "/tmp/sock" . URI for uridecodebin: /tmp/sock Pipeline started. Pipeline state for movie changed from NULL to READY: Pipeline state for movie changed from READY to PAUSED: Error received from element deserializer: Could not decode stream.

Try with current develop and a recent build of gstreamer, gst-plugins-{base, good, bad), gst-libav (e.g. 1.4 version from all repos). I fixed some issues in following commit: https://github.com/mapmapteam/mapmap/commit/835165c89aee93983eec564f1392b1a68f559969

it still needs some work though

Too bad the latest tags are no longer available as Ubuntu packages from https://launchpad.net/~gstreamer-developers/+archive/ubuntu/ppa?field.series_filter=trusty

Won't fix for now.
