Hi everyone, I'm trying to change v360 filter params such as roll, pitch at real-time speed. I'm using avfilter_graph_send_command() to make thing happen. The problem came when the image became larger (4096 × 2160 or larger), it took more time to init a new filter graph. I found that most of the time it spent on running this callback v360_slice() . Firstly, I thought I could vectorize two for loops inside v360_slice() but I was unable to understand the algorithm in it. I tried to increase the number of threads processing the slices but it did not work. I'm appreciated any advice to help me deal with it.
