Capture video from android camera with gstreamer

[alex_malishev]

Hi! I'm working on the project which will be able to capture video from smartphone's camera and send it to server. But now I'm trying to save it in file and my question is:
Does anybody know how to capture video from android camera and save it to file using gstreamer1.0? I have already tried  camerabin plugin. I built this pipeline:

 gst-launch-1.0 camerabin mode=1 filename="/storage/sdcard0/Movies/camera.ogg"

but it doesn't work. I uderstand that I must set viewfinder-sink and camera-src properties, but when I try to make pipeline by using gstreamer functions like this

 data->pipeline = gst_element_factory_make("camerabin", "camerabin");
 g_object_set(data->pipeline, "mode", MODE_VIDEO, NULL);
 sink = gst_element_factory_make ("filesink", NULL);
 g_object_set(sink, "location","/storage/sdcard0/Movies/test.ogg");
 g_object_set(data->pipeline, "viewfinder-sink", sink, NULL);
 g_object_set(data->pipeline, "filename","/storage/sdcard0/Movies/camera-record.ogg", NULL);
 gst_element_set_state(data->pipeline, GST_STATE_READY);

the app crashes and gives me error:

A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x83127d5b in tid 27873 (als.tutorial_51) I add filesink element because when I build pipeline like this:

data->pipeline = gst_parse_launch("camerabin mode=1 filename="/storage/sdcard0/Movies/camera.ogg")

file camera.ogg doesn't create in filesystem.

And I can't set camera-src property, because i don't know what value i should use. In examples peoples use v4l2, but not all devices support this plugin. Also they used ahcsrc, but it gives me error: no elements ahcsrc. I tried to find this element and found out there is no such element in gstreamer1.0, only in gstreamer-0.10 in androidcamera plugin.

Please, help me!

Please get a backtrace of the crash with gdb.

Which version of GStreamer are you using? With 1.8 and newer there is
an ahcsrc element contained in the androidmedia plugin.

Please get a debug log if you have this version, link in the plugin but
still can't use it.

I think, the problem was in my C code, when i tried to build camerabin pipeline.

Now, I'm trying the new version of gstreamer.(ver. 1.8.2), as you sad,  and I got this error when build the project:

There was a bug in 1.8.2 causing this. Try replacing the gstreamer-
1.0.mk with the latest one here:
https://cgit.freedesktop.org/gstreamer/cerbero/tree/data/ndk-build/gstreamer-1.0.mk

I don't know, can you set up your system in English or translate the
error yourself?

Sebastian, Hi again ) I fixed this error by changing gstreamer sdk version and now it's 1.8.0.  I try to run this pipeline :
 gst_parse_launch("ahcsrc ! glimagesink name=vsink sync=false", error); 
but i always get the same error: no element ahcsrc. I'm sure there is plugin androidmedia in sdk directory and I add this plugin in Android.mk
Also when I run playbin pipeline using gstreamer tutorial 5 video from net plays with lags. I should say the internet connection is very fast. 

Thanks.

Please show your Android.mk and also provide a debug log with level 6.
Easiest way to do that is to edit gstreamer_android-1.0.c.in before the
build and change the gst_debug_set_default_threshold() in there to get
GST_LEVEL_LOG as parameter.
