no such pad 'video_%u' in element "qtdemux0"

[Vinod Kesti]

kk,

qtdemux cant be directly linked to decoder as video_%u is some time pad.

Use "pad-added" signal of qtdemux to link qtdemux to avdec_h264.

Below tutorial may help you
https://gstreamer.freedesktop.org/documentation/tutorials/basic/dynamic-pipelines.html?gi-language=c

 /* Connect to the pad-added signal */
*  g_signal_connect (data.source, "pad-added", G_CALLBACK
(pad_added_handler), &data);*
