Víctor Manuel Jáquez Leal	db382cbc3d	videocrop: handle non raw caps features ... Currently, videocrop, only negotiates raw caps (system memory) because it's the type of memory it can modify. Nonetheless, it's also possible for the element to handle non-raw caps when only adding the crop meta is possible, in other words, when downstream buffer pools expose the crop API. This patch enable non-raw caps negotiation. If downstream doesn't expose crop API and negotiated caps are featured, the negotiation fails.

Hou Qi	e037391364	v4l2object: Avoid colorimetry mismatch for streams with invalid colorimetry ... video-info sets gst colorimetry to default value when colorimetry in caps is unparsable or invalid. Then v4l2object uses this gst colorimetry to do mapping with v4l2 colorimetry. This may cause colorimetry mismatch when check mapped gst colorimetry with that read from caps directly. To fix this, need to correct gst colorimetry as that parsed from video-info when check gst_v4l2_video_colorimetry_matches().

Matthew Waters	612102fdbc	gst: don't use volatile to mean atomic ... volatile is not sufficient to provide atomic guarantees and real atomics should be used instead. GCC 11 has started warning about using volatile with atomic operations. https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719 Discovered in https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/868 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/911>	2021-03-18 19:52:53 +11:00
Nirbheek Chauhan	95ef0a1df8	Update docs cache and fix before-send signal doc syntax ... The docs for before-send were missing because of this Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/909>	2021-03-17 15:55:30 +05:30
Nirbheek Chauhan	73fb107a85	rtspsrc: Fix accumulation of before-send signal return values ... Since glib 2.62, the accumulated return values in RUN_CLEANUP override the accumulated return values in RUN_FIRST. Since: 1. We have a default handler that always returns TRUE, and 2. User handlers are only run in RUN_FIRST, and 3. Our accumulator just takes the latest return value We were discarding the return value from the user handler and always sending messages even if the user handler said not to. See https://gitlab.gnome.org/GNOME/glib/-/issues/2352 for more details. This signal does not need RUN_CLEANUP or RUN_FIRST, so just change it to RUN_LAST so that it's emitted exactly once and accumulated once. With this fix, this signal can now be used to intercept PAUSE when going to GST_STATE_NULL so that the server does a TEARDOWN (if necessary) and not a PAUSE, which will confuse other RTSP clients when playing shared media.

Nirbheek Chauhan	55edd59f48	Revert unusable workaround for PAUSE being sent when going NULL ... Directly setting rtspsrc to the NULL state before putting the pipeline in the NULL state usually works, but it can cause a deadlock in some cases, so it's not a reliable mechanism to fix this. This reverts commit f37afdafff: "rtspsrc: Fix state changes from PAUSED to PLAYING" and commit 76d624b2df: "rtspsrc: Do not send PAUSE command when going to GST_STATE_NULL" Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/908>	2021-03-17 14:04:16 +05:30

Sebastian Dröge	242f3cae6d	matroskademux: Fix extraction of multichannel WavPack ... The old code had a couple of issues that all lead to potential memory safety bugs. - Use a constant for the Wavpack4Header size instead of using sizeof. It's written out into the data and not from the struct and who knows what special alignment/padding requirements some C compilers have. - gst_buffer_set_size() does not realloc the buffer when setting a bigger size than allocated, it only allows growing up to the maximum allocated size. Instead use a GstAdapter to collect all the blocks and take out everything at once in the end. - Check that enough data is actually available in the input and otherwise handle it an error in all cases instead of silently ignoring it. Among other things this fixes out of bounds writes because the code assumed gst_buffer_set_size() can grow the buffer and simply wrote after the end of the buffer. Thanks to Natalie Silvanovich for reporting.

Sebastian Dröge	6c461e90bc	matroskademux: Initialize track context out parameter to NULL before parsing ... Various error return paths don't set it to NULL and callers are only checking if the pointer is NULL. As it's allocated on the stack this usually contains random stack memory, and more often than not the memory of a previously parsed track. This then causes all kinds of memory corruptions further down the line. Thanks to Natalie Silvanovich for reporting.

Nirbheek Chauhan	76d624b2df	rtspsrc: Do not send PAUSE command when going to GST_STATE_NULL ... This usually doesn't matter, but it is disruptive when streaming from a shared media since it will pause all other clients when any client exits. This new behaviour is opt-in and should be safe because you need to set the NULL state on rtspsrc directly, instead of just on the pipeline. See the updated documentation for an explanation.

Some cameras (e.g. HikVision DS-2CD2732F-IS) return "551 Option not supported" when a command is sent that is not implemented (e.g. PAUSE). Instead; it should return "501 Not Implemented". This is wrong, as previously, the camera did announce support for PAUSE in the OPTIONS. In this case, handle the 551 as if it was 501 to avoid throwing errors to application level. */ Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/merge_requests/885>	2021-03-04 13:07:49 +01:00
Hou Qi	fc5a1e468b	v4l2videodec: Do not expose profiles/levels in vp8/vp9 template caps ... Vp8/vp9 supported profiles/levels are listed in decoder sink caps, but there is no parser for these two formats and the demuxers also don't have these information. It causes negotiation fail between demuxers and decoder when check caps "accept = gst_caps_is_subset (caps, template_caps);".
