[gst-devel] See and record a webcam stream

[Carlos Castro]

Hi everyone,

I'm trying to build a simple GTK app using GST as a backend to see and
record a webcam stream.

I can do both but separately... My problem is doing both at the same time.
What I'm trying to accomplish is this:

gst-launch-0.10 v4l2src \
! videorate \
! video/x-raw-yuv,framerate=25/2 \
! ffmpegcolorspace \
! tee name=t1 \
! queue \
! xvimagesink sync=false t1. \
! queue \
! theoraenc quality=16 \
! oggmux name=mux osssrc \
! audio/x-raw-int,rate=22050,channels=1 \
! queue \
! audioconvert \
! vorbisenc quality=0.2 \
! mux. mux. \
! queue \
! filesink location=test.ogg

My code is this:

...
        m_pipeline = gst_pipeline_new ("pipeline");
	m_bin = gst_bin_new ("bin");
	m_source = gst_element_factory_make ("v4l2src", "video_src");
	m_videorate = gst_element_factory_make ("videorate", "videorate");
	m_framerate = gst_element_factory_make
("video/x-raw-yuv,framerate=25/2", "framerate");
	m_colorspace = gst_element_factory_make ("ffmpegcolorspace", "colorspace");
	m_tee = gst_element_factory_make ("tee name=t1", "t1");
	m_queue = gst_element_factory_make ("queue", "queue");
	m_imagesink = gst_element_factory_make ("xvimagesink sync=false t1.",
"imagesink");
	m_queue2 = gst_element_factory_make ("queue", "queue2");
	m_videoenc = gst_element_factory_make ("theoraenc quality=16", "video_enc");
	m_mux = gst_element_factory_make ("oggmux name=mux osssrc", "mux");
	m_audio = gst_element_factory_make
("audio/x-raw-int,rate=22050,channels=1", "audio");
	m_queue3 = gst_element_factory_make ("queue", "queue3");
	m_audiocon = gst_element_factory_make ("audioconvert", "audio_con");
	m_audioenc = gst_element_factory_make ("vorbisenc quality=0.2", "audio_enc");
	m_mux2 = gst_element_factory_make ("mux. mux.", "mux2");
	m_queue4 = gst_element_factory_make ("queue", "queue4");
	m_file = gst_element_factory_make ("filesink location=test.ogg", "filesink");

gst_bin_add_many (GST_BIN (m_bin), m_source, m_videorate, m_framerate,
m_colorspace, m_tee, m_queue, m_imagesink, m_queue2, m_videoenc,
m_mux, m_audio, m_queue3, m_audiocon, m_audioenc, m_mux2, m_queue4,
m_file , NULL);
	gst_bin_add (GST_BIN (m_pipeline), m_bin);
	gst_element_link_many (m_source, m_videorate, m_framerate,
m_colorspace, m_tee, m_queue,
			m_imagesink, m_queue2, m_videoenc, m_mux, m_audio, m_queue3,
m_audiocon, m_audioenc, m_mux2, m_queue4, m_file , NULL);

    if (GST_IS_X_OVERLAY (m_imagesink))
        gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (m_imagesink),
GPOINTER_TO_INT (window));

    gst_element_set_state (m_pipeline, GST_STATE_PLAYING);
...

Can anyone help me on what I'm doing wrong?


Thanks,
