Need help for rezising video.

Hello,
I have created a plugin that displays a video in an evas image. Here is my problem: When I resize the picture I am calling "evas_object_image_fill_set", it works correctly, however the consumption of CPU is just horrible, more than 120% ! If I leave it in normal size, the consumption of CPU is normal. I want to know if there is a way to resize the video (via gstreamer) in my plugin. Have you any idea? May be I could create a function "buffer alloc" (gstbase_sink_class->buffer_alloc = mybufferalloc) and modify the buffer in it ? I know that there is "videoscale" but I do not know how to use it inside the plugin. Thank you in advance for your reply, Sincerely, Nicolas. Ps: sorry for bad english. ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

Hi..
If you are looking for a plugin to resize the image ..i think capsfilter will help you..

Hi Lijin,
Thanks for your reply. But how capsfilter can help me ? I only see in the doc: capsfilter — Pass data without modification, limiting formats Regards, Nicolas. ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

You will have to create a capsfilter element and set the relevant caps on it (with the frame size you require). Then follow it up with a video scale element. (...->decoder->capsfilter->videoscale->...->sink)
Check out this doc here - Rohit

Hi...
This is how i used the capsfilter vflt=gst_element_factory_make("capsfilter","imagefilter"); if(!vflt)
{ g_print("\n Image Filter element could not be created \n"); return 0; } g_object_set(G_OBJECT(vflt),"caps",gst_caps_new_simple("image/jpeg",
"width",G_TYPE_INT,320, "height",G_TYPE_INT,240,
"framerate",GST_TYPE_FRACTION,30,1, NULL),NULL);
I think this will help you...

Hi,
Thanks for your reply. Ok, i do: pipeline = gst_pipeline_new ("pipeline"); playbin = gst_element_factory_make ("playbin2", "playbin"); // Filter filter = gst_element_factory_make ("capsfilter", "filter"); caps = gst_caps_new_simple ("video/x-raw-yuv", "format", GST_TYPE_FOURCC, GST_MAKE_FOURCC ('I', '4', '2', '0'), "width", G_TYPE_INT, 800, "height", G_TYPE_INT, 600, NULL); g_object_set ((GObject*) filter, "caps", caps, NULL); // My sink sink = gst_element_factory_make ("evasvideosink", "sink"); g_object_set ((GObject*) playbin, "video-sink", sink, NULL); // Tell to playbin2 to use my sink g_object_set ((GObject*) playbin, "uri", argv[1], NULL); g_object_set ((GObject*) sink, "evas-object", video, NULL); // Tell my sink to use evas image gst_bin_add_many (GST_BIN (pipeline), playbin, filter, NULL); gst_element_set_state (pipeline, GST_STATE_PLAYING); It does not change the size of the video, is this the correct way ?

The capsfilter isn't going to do anything for you unless something in the pipeline is able to make the needed changes to match the caps. Before the capsfilter you should add a videoscale element so it is able to match the requested caps of the filter. You may also want to take a gander at the ffmpeg_colorspace and videorate elements as well.
As a side note: You can simplify the creation of the caps with the gst_caps_from_string( "video/x-raw-yuv, format=I420, width=800, height=600") call. You need to unref the caps when you're done with it as well. Just my 2c.

@Nicolas You could use the capsfilter element like this as well - caps = gst_caps_new_simple ("video/x-raw-rgb", "bpp", G_TYPE_INT, 24,
"depth", G_TYPE_INT, 24, NULL);
gst_element_link_filtered(capsfilter, videosink, caps); (Considering videoscale element is already linked to capsfilter on to its left.) instead of doing a gst_object_set()...
Of course the choice between the 2 depends on your convenience.

Sorry typo - change the caps string to suit your needs.

Hi,
Thanks everyone for your reply. Can you send me your pipeline (in C or Python), because mine does not work ?

Hi,
In fact, i made a new pipeline just for testing and my problem is, i don't know what to link together !

You always want to check the return result from any of the link calls. Also, to link the decodebin you have to listen for the pad-added (or is it new-decoded-pad, I can't recall) and link when it's available. It won't be available until the decodebin has setup the decoders and such.

You itrerate over the pad (that were added during the preroll). You then link your sink in the correct pad.

The videodecoder is ouputing a certain size and you want it to be scaled to the size of your evas widget. Just add a videoscale between the decoder and the evassink and when the window is resized set update your caps. Have a look at ximagesink (this won't resize itself as well and relies on videoscale).
