Hi, here a simplified pipeline
GstApp ! queue ! tee ! queue ! glupload ! glcolorconvert ! myglfilter ! glimagesink
tee ! queue ! videoconvert ! jpegenc ! multifilesink
In GstApp, a custom GstMeta is attached with all GstBuffer.
In multifilesink, i can read the GstMeta attached to GstBuffer.
In myglfilter, in virtual function :
static gboolean
gst_gev_gloverlay_filter (GstGLFilter * filter, GstBuffer * inbuf, GstBuffer * outbuf)
{
GevInfosMeta *meta = gst_buffer_get_gev_infos_meta(inbuf);
if (meta != 0) {
g_print("Timestamp : %lu", meta->timestamp);
}
else {
g_print("Timestamp : NULL\n");
}
gst_gl_filter_filter_texture(filter, inbuf, outbuf);
}
i can't read any custom Meta (output Timestamp : NULL)
What is wrong ?
Thanks
