However all VA surfaces\nmust have the same dimensions, in particular for cases where frame\nactual dimensions is different than the coded one. This is necessary as\none cannot control what IGBP slot will be used in what context, so all\nVA surfaces must be interchangeable.\n\nUse of DRM prime can be disabled by setting system property\ndebug.ffmpeg-codec2.hwaccel.drm = 0.","shortMessageHtmlLink":"Zero-copy VA-API decoding using gralloc DRM prime handle"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAADC_pI1wA","startCursor":null,"endCursor":null}},"title":"Activity · goffioul/external-stagefright-plugins"}
