function GstVideo.VideoInfoDmaDrm.prototype.new_from_caps(caps: Gst.Caps): {
    // javascript wrapper for 'gst_video_info_dma_drm_new_from_caps'
}

Parse caps to generate a GstVideo.VideoInfoDmaDrm. Please note that the caps should be a dma drm caps. The GstVideo.prototype.video_is_dma_drm_caps can be used to verify it before calling this function.

function GstVideo.VideoInfoDmaDrm.prototype.to_caps(): {
    // javascript wrapper for 'gst_video_info_dma_drm_to_caps'
}

Convert the values of drm_info into a Gst.Caps. Please note that the caps returned will be a dma drm caps which sets format field to DMA_DRM, and contains a new drm-format field. The value of drm-format field is composed of a drm fourcc and a modifier, such as NV12:0x0100000000000002.

GstVideo.VideoInfoDmaDrm.prototype.to_video_info

function GstVideo.VideoInfoDmaDrm.prototype.to_video_info(): {
    // javascript wrapper for 'gst_video_info_dma_drm_to_video_info'
}

Convert the GstVideo.VideoInfoDmaDrm into a traditional GstVideo.VideoInfo with recognized video format. For DMA kind memory, the non linear DMA format should be recognized as GstVideo.VideoFormat.DMA_DRM. This helper function sets info's video format into the default value according to drm_info's drm_fourcc field.

GstVideo.prototype.video_info_dma_drm_from_video_info

function GstVideo.prototype.video_info_dma_drm_from_video_info(info: GstVideo.VideoInfo, modifier: Number): {
    // javascript wrapper for 'gst_video_info_dma_drm_from_video_info'
}

Fills drm_info if info's format has a valid drm format and modifier is also valid
