` static const AVFilterPad gltransition_inputs[] = { { .name = "from", .type = AVMEDIA_TYPE_VIDEO, .config_props = setup_gl, }, { .name = "to", .type = AVMEDIA_TYPE_VIDEO, }/, //pacth here add comment {NULL} / };

static const AVFilterPad gltransition_outputs[] = { { .name = "default", .type = AVMEDIA_TYPE_VIDEO, .config_props = config_output, } /, //pacth here add comment {NULL} / }; `

description of AVFilterPad can't add {NULL}
