* v4l2: log buffer copies on queue underrun in perf categoryStefan Kost2009-09-111-0/+5
| | | | | v4l2src has a slow path where it does buffer-copies when it runs out of queued buffers. Log this to performance category to help monitoring it.
* v4l2src: add support for mpeg formatsWim Taymans2009-09-071-0/+3

* v4l2sink: change where buffers get dequeuedRob Clark2009-08-041-1/+1
| | | | It seems to cause strange occasional high latencies (almost 200ms) when dequeuing buffers from _buffer_alloc(). It is simpler and seems to work much better to dqbuf from the same thread that is queuing the next buffer.
* v4l2: Add v4l2sink elementRob Clark2009-08-041-1267/+53
| | | | | | | | | | | This also does the following changes: (1) pull the bufferpool code out into gstv4l2bufferpool.c, and make a bit more generic so it can be used both for v4l2src and v4l2sink (2) move some of the device probing/configuration/caps stuff into gstv4l2object.c so it does not have to be duplicated between v4l2src and v4l2sink Fixes bug #590280.
* v4l2: Fix v4l2src on OpenSolarisElaine Xiong2009-07-191-6/+14
| | | | | | | | The v4l2 driver for USB webcams on OpenSolaris does not support select() calls. Detect when select() fails, and skip polling the device afterward, which restores the pre 0.10.14 behaviour on OpenSolaris. Signed-off-by: Jan Schmidt <thaytan@noraisin.net>
* v4l2src: move duplicated timestamping and buffer metadata code to _create()Stefan Kost2009-03-251-29/+1
| | | | This will include the latency changes also in the mmap case.
* v4l2src: remove win32 ifdefs introduced by commit ↵Stefan Kost2009-03-251-5/+0
| | | | | | cff3f46760eac74c9bbd7a36aca44fedf327424b V4l2src is under sys and does not exists/run under windows anyway.
* v4l2src: log details if we have them, needed for #575391Stefan Kost2009-03-151-2/+2

* v4l2src: fix pads, so that they are subset of template capsStefan Kost2009-03-061-4/+9
| | | | Do not add w=0 | h=0. When we can't get a framerate add fraction range.
* Wait for a frame to become available before capturing itSjoerd Simons2009-03-011-2/+29
| | | | | | | | | | Use GstPoll to wait for the fd of the video device to become readable before trying to capture a frame. This speeds up stopping v4l2src a lot as it no longer has to wait for the next frame, especially when capturing with low framerates or when the video device just never generates a frame (which seems a common issue for uvcvideo devices) Fixes bug #563574.
* v4l2src: Make sort_by_frame_size conditionally compiledLevente Farkas2009-02-231-0/+2
| | | | | | | sort_by_frame_size is declared static and only used inside an ifdef, so use the same ifdef to define the function. Fixes #572185 Signed-off-by: David Schleef <ds@schleef.org>

Fixes probed caps for the camera in my HP2133 mini notebook and makes v4l2src default to a decent size.

Original commit message from CVS: * sys/v4l2/gstv4l2src.c: * sys/v4l2/v4l2src_calls.c: When probing the formats and sizes a camera supports, make sure the best ones (highest resolution, prefered format) end up at the beginning of the probed caps and the less desirable ones at the end. This is important because the order within the caps matters for things like fixation and negotiation, ie. what format is chosen in the end. With recent kernels, the current probing code will end up querying the supported sizes from lowest resolution to highest resolution, adding them to the probed caps in that order, resulting to v4l2src fixating to the lowest possible resolution if downstream does not express a size preference. Also make up a somewhat random ranking of prefered output formats for the same reason. Fixes #485828.

(gst_v4l2src_capture_start): Call buffer_pool_activate instead of queueing the frames directly. * sys/v4l2/gstv4l2src.h (struct _GstV4l2BufferPool): Make this a real MiniObject instead of rolling our own refcounting and finalizing. Give it a lock. (struct _GstV4l2Buffer): Remove one intermediary object, having the buffers hold the struct v4l2_buffer directly. * sys/v4l2/gstv4l2src.c (gst_v4l2src_set_caps): Pass the caps to capture_init so that it can set them on the buffers that it will create. (gst_v4l2src_get_read): For better or for worse, include the timestamping and offsetting code here; really we should be using bufferalloc though. (gst_v4l2src_get_mmap): Just make grab_frame return one of our preallocated, mmap'd buffers.

Original commit message from CVS: 2007-06-05 Andy Wingo <wingo@pobox.com> * sys/v4l2/gstv4l2src.c (gst_v4l2src_start, gst_v4l2src_stop): Add some useless comments. * sys/v4l2/v4l2src_calls.c (gst_v4l2src_capture_init): Don't queue frames before calling STREAMON, that might leave them in a state where they can't be dequeued if we go back to NULL without calling STREAMON, according to the docs. (gst_v4l2src_capture_start): Enqueue buffers here instead, right before we call STREAMON. (gst_v4l2src_capture_deinit): Remove crack to work around dequeue failures. (For me this code hung.) The pool refcounting is still crack; added a note to that effect.

Original commit message from CVS: 2007-05-30 Andy Wingo <wingo@pobox.com> * sys/v4l2/v4l2src_calls.h: * sys/v4l2/v4l2src_calls.c (gst_v4l2src_fill_format_list): Store the format list in the order that the driver gives it to us. (gst_v4l2src_probe_caps_for_format_and_size) (gst_v4l2src_probe_caps_for_format): New functions, fill GstCaps based on the capabilities of the device. (gst_v4l2src_grab_frame): Update for object variable renaming. (gst_v4l2src_set_capture): Update to be strict in its parameters, as in the set_caps below. (gst_v4l2src_capture_init): Update for object variable renaming, and reflow. (gst_v4l2src_capture_start, gst_v4l2src_capture_stop) (gst_v4l2src_capture_deinit): Update for object variable renaming. (gst_v4l2src_update_fps, gst_v4l2src_set_fps) (gst_v4l2src_get_fps): Remove; these functions don't have much meaning outside of an atomic set_caps method. (gst_v4l2src_buffer_new): Don't set buffer duration, it is not known. * sys/v4l2/gstv4l2tuner.c (gst_v4l2_tuner_set_channel): Remove call to update_fps; not sure about this change. (gst_v4l2_tuner_set_norm): Work around the fact that for the moment we don't have an update_fps_func. * sys/v4l2/gstv4l2src.h (struct _GstV4l2Src): Don't put v4l2 structures in the object, just store what we need. Do store the probed caps of the device. Don't store the current frame rate. * sys/v4l2/gstv4l2src.c (gst_v4l2src_init): Remove the update_fps_function, for now. Update for new object variable naming. (gst_v4l2src_set_property, gst_v4l2src_get_property): Update for new object variable naming. (gst_v4l2src_v4l2fourcc_to_structure): Rename from ..._to_caps. (gst_v4l2_structure_to_v4l2fourcc): Rename from ...caps_to_.... (gst_v4l2src_get_caps): Rework to probe the device for supported frame sizes and frame rates. (gst_v4l2src_set_caps): Rework to be strict in the given parameters: if someone asks us to have a certain size and rate, that is what we configure. (gst_v4l2src_get_read): Update for object variable naming. Don't leak buffers on short reads. (gst_v4l2src_get_mmap): Update for object variable naming, and add comments. (gst_v4l2src_create): Update for object variable naming.
