[FFmpeg-devel] [PATCH V1 01/11] lavfi/spp: add "quality" option in runtime change path

[Jun Zhao]

From: Jun Zhao <barryjzhao at tencent.com>

it's stranage to use option "level" in runtime change path but used
"quality" in option, add "quality" in runtime change path, it's more
intuitive and keep the "level" for compatibility.
