2024-06-30media: venus: fix use after free in vdec_closeDikshita Agarwal1-0/+1
There appears to be a possible use after free with vdec_close(). The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst. Fix it by cancelling the work in vdec_close.

Modify section "Video and Sliced VBI Looping" in Documentation to explain the vivid loopback support for video across multiple vivid instances. Previous documentation is out-of-date as it was explaining looping in a single vivid instance only.

Instead of using hardwired video loopback limited to a single vivid instance, use the new 'Connected To' controls to only loopback if an HDMI or S-Video input is connected to another output, which can be in another vivid instance. Effectively this emulates connecting and disconnecting an HDMI/S-Video cable. The Loop Video control is dropped since it has now been replaced by the new 'Connected To' controls. The Display Present has also been dropped since it no longer fits.

2024-06-28media: vivid: Add 'Is Connected To' menu controlsDorcas Anono Litunya3-17/+401
The video loopback functionality in vivid is very crude. What we really want is to be able to emulate connecting an HDMI or S-Video input to an HDMI or S-Video output, and the input and output can be in different vivid instances. Effectively this emulates what happens when you physically connect an HDMI or S-Video cable between two devices. In particular, this makes prototyping with vivid much more realistic. This patch creates a menu control for each HDMI or S-Video input. The menu control starts with "Test Pattern Generator" and "None" (i.e. disconnected). After that up to 62 HDMI or S-Video outputs are listed that you can connect the input to. If there are more than 62 HDMI or S-Video outputs, then those will not be included in the menu (currently menucontrols have max 64 entries). If an input is connected to an output, then all other 'Connected To' controls are updated to exclude that output to avoid having multiple inputs connected to the same output.
