* | lavfi/vulkan: use av_get_random_seed instead of rand | Lynne | 2020-05-29 |
| | | | | | | | | We need at least a few bits of entropy to determine the start index of each queue, in order to let filters run in parallel as much as possible, and rand() is not thread safe and disrupts any external API's usage of rand, so instead replace it with av_get_random_seed. While it has more overhead than rand, we only run it once per filter upon init. | ||
* | lavfi/vulkan: use all enabled queues in the queue family | Lynne | 2020-05-23 |
| | | | | | This should significantly improve the performance with certain filterchains. | ||
* | overlay_vulkan: add support for overlaying images with an alpha channel | Lynne | 2020-04-23 |

* | lavfi: add an overlay_vulkan filter | Lynne | 2020-02-04 |
This commit adds a basic, non-converting overlay filter for Vulkan. |
