mpegts: Can't distinguish extension_descriptor via gst_mpegts_find_descriptor
Submitted by Gabby Park
There are extension_descriptor (descriptor_tag == 0x7F, descriptor_tag_extension) in ES loop of PMT(Program Map Table). The decriptor_tag value 0x7F will be shared between extension_descriptor but, our gst_mpegts_find_descriptor() can distinguish depend on only descriptor_tag.
So if there are one more extension_descriptor in same ES loop of PMT, then we only get the first of extension_descriptor.
This specification is about DVB standard. In my opinion, it looks like that we need new function for find descriptor.
I want to hear your feedback.
