Hi, I was just looking at FFmpegImageStream, I am not very familiar with this code, but I have some questions.
It is not immediately clear to me how FFmpegImageStream::publishNewFrame is thread safe. It seems like the image data is set (setImage) from the video decoder thread. The image then uses a pointer to one of the buffers of the video decoder (of which the contents might also change ?). FFmpegImageStream also doesn't seem to override requiresUpdateCall, which I believe will result in the texture not being dynamic (Texture2D::setImage). Which could be used, for example in StateSet::computeDataVariance(), to determine whether the StateSet should be dynamic (which is needed for multithreaded rendering). If anyone could shed more light on this subject, it would be very much appreciated. Thank you.
