ffv1_vulkan: slice count of the encoder - #505
Merged

Conversation
With the Vulkan encoder, the slice count is the FFmpeg default (32x32 slices, limited to the frame size, for the parallelism of GPUs) instead of ours (e.g. 64 slices for HD): the parsers set slice_x and slice_y to 0 for the encoder default and no -slices option is given to FFmpeg.
