From 961e60a89bc60e760707892539ccd7c6d283ef01 Mon Sep 17 00:00:00 2001 From: Matthias Vogelgesang Date: Thu, 13 Feb 2014 14:54:34 +0100 Subject: Fix #28: Add buffered recording to base class This change adds new properties ::buffered and ::num-buffers to the base class. If ::buffered is TRUE, uca_camera_start_recording will spawn a new thread which will call the camera-specific grab. Any call to uca_camera_grab will return the next item from the ring buffer. --- bin/gui/control.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'bin/gui/control.c') diff --git a/bin/gui/control.c b/bin/gui/control.c index d4191a1..b02c42d 100644 --- a/bin/gui/control.c +++ b/bin/gui/control.c @@ -752,6 +752,7 @@ record_frames (gpointer args) buffer = uca_ring_buffer_get_write_pointer (data->buffer); uca_camera_grab (data->camera, buffer, NULL); + uca_ring_buffer_write_advance (data->buffer); if (error == NULL) { n_frames++; @@ -949,6 +950,7 @@ download_frames (ThreadData *data) while (error == NULL) { buffer = uca_ring_buffer_get_write_pointer (data->buffer); uca_camera_grab (data->camera, buffer, &error); + uca_ring_buffer_write_advance (data->buffer); gdk_threads_enter (); gtk_adjustment_set_value (data->download_adjustment, current_frame++); -- cgit v1.2.3
