Mapping stream types to human readable description

[cybin]

Hi!

I'm working on the XML output and would like to fill the description fields with something readable. I can't find a table or list to match the numeric type values to something else.

Taken from the comments there must be something to provide useful information:

<streams>
  <stream type="27" pid="213" description="AVC Video stream, ITU-T Rec. H.264 | ISO/IEC 14496-10"/>
  <stream type="4" pid="330" description="AUDIO" language_code="fin"/>
</streams>

Thanks in advance.

Sounds interesting. Do you have to generate those descriptions based on the type number?

At the moment, I don't know what these type fields are. I don't expect it to be an absolute value to map to onto a table, but maybe it's bit mask to check video/audio, codecs, and other parameters to build a readable description. If anyone has got a hint on that, I would really appreciate it.

I have just committed a pull request with an implementation of XML output. Thanks for this table, I used it in the implementation.
