* avdevice/lavfi: Remove redundant av_packet_unref()Andreas Rheinhardt2020-09-061-1/+0
| | | | | | | | | 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 Rheinhardt2020-09-011-1/+0
| | | | | | | | | | 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 Barsnick2020-08-151-0/+9
| | | | | | | | | | | | 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 Thompson2020-08-091-0/+9
| | | | | | | 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 Thompson2020-08-091-15/+40
| | | | | This is provided by GetFB2, but we still need the option for cases where that isn't available.
* kmsgrab: Use GetFB2 if availableMark Thompson2020-08-091-19/+199
| | | | | | | | | | | | 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).

* avdevice/v4l2: Remove av_assert0 when format not supportedAndriy Gelman2019-11-061-1/+2
| | | | | | | | | | | | | | | | | Before this commit an av_assert0 would fail if a v4l2 device did not support a target format. For example, ./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts - would signal an abort if /dev/video0 did not support h264. The new behaviour is to return an AVERROR(EINVAL) error code. An av_assert0 has been added to verify this return.

* lavd/v4l2: produce a 0 byte packet when a dequeued buffer's size is unexpectedStephan Hilb2019-07-301-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Behave like we do for V4L2_BUF_FLAG_ERROR, implemented in commit 28f20d2ff4 . For some devices (probably also related to the V4L driver implementation) it happens that when invoking the ioctl DQBUF, the returned buffer is not of the expected size. Here are two examples for such occurrences: [video4linux2,v4l2 @ 0x258b440] Dequeued v4l2 buffer contains 609596 bytes, but 614400 were expected. Flags: 0x00000001. /dev/video1: Invalid data found when processing input [video4linux2,v4l2 @ 0x225f440] Dequeued v4l2 buffer contains 609508 bytes, but 614400 were expected. Flags: 0x00000001. /dev/video1: Invalid data found when processing input For the ffmpeg CLI tool this means it will stop capturing and exit. The described behaviour was observed at least with one OmniVision USB web cam and with some stk1160 devices. If you search the web for the error message, you will find quite a few instances of this problem. Some of them experienced on other devices.
