I'm using this module for postprocessing of my video stream. Especially for adjustment of brightness, saturation and contrast, by changing the modules properties.<o:p></o:p> The decoding of the stream with vaapi, as well as the gl-texture-upload by glupload works like a charm. But when the stream is running and I’m trying to change the properties for brightness, saturation or contrast many times (in a calibration manner), I’m running out of memory.<o:p></o:p> Is it possible that there is a huge memory leak? When I’m steadily calibrating the mentioned properties for about 30 secs, I get an increase of memory about 2 GB. (I know from 14.4.4, that there were some issues related to a mutual exclusive color calibration, which were fixed by a patch.) <o:p></o:p> Could someone verify this issue?<o:p></o:p> Below I’ve attached the relevant code sequences:<o:p></o:p> Construction:<o:p></o:p> …<o:p></o:p> auto postproc = gst_element_factory_make( "vaapipostproc", "postproc" );<o:p></o:p> auto upload = gst_element_factory_make( "glupload", "upload" );<o:p></o:p> GstCaps* caps = gst_caps_from_string( "video/x-raw(memory:DMABuf), format=RGBA" );<o:p></o:p> if( !gst_element_link_filtered( postproc, upload, caps ) )<o:p></o:p> …<o:p></o:p> Setter for Properties (the lines below are executed very often, while stream is running):<o:p></o:p> ...<o:p></o:p> gfloat tmp = 0.5<o:p></o:p> g_object_set( G_OBJECT( vaapipostproc ), "brightness", tmp, NULL );<o:p></o:p> ...<o:p></o:p> Not sure whether i’m doing wrong, or there is sth broken in vaapipostproc. <o:p></o:p> Kind regards Michael<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> </div> <div style="background-color:#FFFFFF"> Bitte beachten / Please note! <div style="font-size:12pt; line-height:10pt; font-family:'times roman',serif;"> ******************************************************************************* AGCO GmbH Sitz der AGCO GmbH: Johann-Georg-Fendt-Str.4, 87616 Marktoberdorf, Germany Registergericht Amtsgericht Kempten HRB 10327 Geschäftsführer: Christoph Groeblinghoff, Ingrid Bussjaeger-Martin, Dr. Heribert Reiter, Ekkehart Glaeser Vorsitzender des Aufsichtsrates: Torsten Dehner ******************************************************************************* Diese E-Mail ist nur für den Empfänger bestimmt, an den es gerichtet ist und kann vertrauliches bzw. unter das Berufsgeheimnis fallendes Material enthalten.
