Hello everybody,
I use GStreamer Editing Services for simple operations such as cutting parts
of an audio-video clip.
I noticed that if I try to insert a high-resolution video (3840 x 2160) and
play, the memory occupied by the application increases to 1.5Gb and the CPU
increases to 80-95% and is maintained as long as I play. Is there any method
to reduce CPU / memory to a reasonable value?
I use GStreamer 1.16.1, do you think the newer versions are more optimized?
The code used is not much different from the one below:
#include <stdlib.h>
#include <ges/ges.h>
#include <stdlib.h>
int main(int argc, char ** argv)
{
GESPipeline *pipeline;
GESTimeline *timeline;
GESTrack *tracka, *trackv;
GESLayer *layer;
GMainLoop *mainloop;
guint i;
gst_init(&argc, &argv);
ges_init(); /* Initialize the GStreamer Editing Services */
timeline = ges_timeline_new(); /* This is our main GESTimeline */
tracka = GES_TRACK(ges_audio_track_new());
trackv = GES_TRACK(ges_video_track_new());
layer = ges_layer_new(); /* We are only going to be doing one layer of
clips */
if (!ges_timeline_add_layer(timeline, layer)) /* Add the tracks and the
layer to the timeline */
return -1;
if (!ges_timeline_add_track(timeline, tracka))
return -1;
if (!ges_timeline_add_track(timeline, trackv))
return -1;
/* Here we've finished initializing our timeline, we're
* ready to start using it... by solely working with the layer ! */
gchar *uri1 = gst_filename_to_uri("C:\\Users\\neluc\\Documents\\KSV1\\Roger
Federer.mp4", NULL);
GESUriClip *src1 = ges_uri_clip_new(uri1);
g_assert(src1);
g_free(uri1);
ges_layer_add_clip(layer, (GESClip *)src1);
pipeline = ges_pipeline_new();
if (!ges_pipeline_set_timeline(pipeline, timeline)) /* Add the timeline to
that pipeline */
return -1;
/* We set the pipeline to playing ... */
gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING);
mainloop = g_main_loop_new(NULL, FALSE);
g_main_loop_run(mainloop);
return 0;
}
