vaapidecode ranking

Hi,

I try to use avdec_h264 instead of vaapidecode in decodebin because of some issues in vaapidecode (artefact on j1800/j1900 Intel processors).

I use this code to ‘unregister’ vaapidecode:

void unreg_vaapi()

{

GstRegistry* reg = gst_registry_get();

GstPluginFeature* vaapi_decode = gst_registry_lookup_feature(reg, "vaapidecode");

GstPluginFeature* avdec_decode = gst_registry_lookup_feature(reg, "avdec_h264");

if(vaapi_decode == NULL)

{

g_print("vaapidecode not found\n");

return;

}

if(avdec_decode == NULL) {

g_print("avdec_h264 not found\n");

}

else

{

g_print("Rank of avdec_h264 is: %i\n", gst_plugin_feature_get_rank(avdec_decode));

gst_object_unref(avdec_decode);

}

g_print("Rank of vaapidecode was: %i\n", gst_plugin_feature_get_rank(vaapi_decode));

gst_plugin_feature_set_rank(vaapi_decode, GST_RANK_NONE);

g_print("Rank of vaapidecode new: %i\n", gst_plugin_feature_get_rank(vaapi_decode));

gst_object_unref(vaapi_decode);

}

But it doesn’t work as expected.

Before calling the function, vaapidecode is ranked f.e. on 267, after calling its 0.

But decodebin is using vaapidecode and not aved_h264.

Why?

After removing gstreamer-vaapi, avdec_h264 is used, so there should be something else to do.

Working totally without vaapi is not the solution, because I need this for SD-Material.

Regards

Bernhard

I guess you should do the same for vaapidecodebin
