* avdevice/decklink_dec: fix build with older SDKMarton Balint2020-09-15
| | | | | | | | | Apparently bmdFormatUnspecified needs SDK 11.0. It is just a fancy way of checking for zero, so let's do that instead. Fixes build issue since f1b908d20a8. Signed-off-by: Marton Balint <cus@passwd.hu>

* avdevice/lavfi: Remove redundant av_packet_unref()Andreas Rheinhardt2020-09-06
| | | | | | | | | Since bae8844e35147f92e612a9e0b44e939a293e5bc9, the AVPacket that is intended to be used to return the demuxed packet is automatically unreferenced when the demuxer returns an error. This makes an av_packet_unref() in the lavfi demuxer redundant. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avdevice/lavfi: Don't set pkt->size to the value it already hasAndreas Rheinhardt2020-09-01
| | | | | | | | | | av_new_packet() already sets the size. And if the packet is not allocated by av_new_packet() (which seems to be impossible atm), both pkt->size as well as size are 0, so setting it again is unnecessary in this scenario, too.

* avdevice/xcbgrab: check return values of xcb query functionsMoritz Barsnick2020-08-15
| | | | | | | | | | | | Fixes #7312, segmentation fault on close of X11 server xcb_query_pointer_reply() and xcb_get_geometry_reply() can return NULL if e.g. the X server closes or the connection is lost. This needs to be checked in order to cleanly exit, because the returned pointers are dereferenced later.

* kmsgrab: Add more supported formatsMark Thompson2020-08-09
| | | | | | | X2RGB10 tested on both Intel Gen9 and AMD Polaris 11. NV12 tested on Intel Gen9 only - since it has multiple planes, this requires GetFB2. Also add some comments to split the list up a bit.
* kmsgrab: Don't require the user to set framebuffer formatMark Thompson2020-08-09
| | | | | This is provided by GetFB2, but we still need the option for cases where that isn't available.
* kmsgrab: Use GetFB2 if availableMark Thompson2020-08-09
| | | | | | | | | | | | The most useful feature here is the ability to automatically extract the framebuffer format and modifiers. It also makes support for multi-plane framebuffers possible, though none are added to the format table in this patch. This requires libdrm 2.4.101 (from April 2020) to build, so it includes a configure check to allow compatibility with existing distributions. Even with libdrm support, it still won't do anything at runtime if you are running Linux < 5.7 (before June 2020).

| | | | | | | | | | | | Apparently the changes from 3c9185bf3a83395d12a987f626dbdb985eac4320 aren't enough; even with that in place, I got errors like this when trying to build for iOS: src/libavdevice/avfoundation.m:135:5: error: 'AVCaptureDeviceTransportControlsPlaybackMode' is unavailable: not available on iOS AVCaptureDeviceTransportControlsPlaybackMode observed_mode; ^
