IMA VAST Google IMA Tracking Macros

I am currently writing a similar IMA implementation, since IMA is not supported on the different platforms I work with.

When the IMA sends tracking events, it replaces a specific macro in the URLs. See Values [XXXXX] in the URL below.

 https://video-ad-stats.googlesyndication.com/video/client_events?event=3&web_property=ca-pub-2226646527662415&cpn=[CPN]&break_type=[BREAK_TYPE]&slot_pos=[SLOT_POS]&ad_id=[AD_ID]&ad_sys=[AD_SYS]&ad_len=[AD_LEN]&p_w=[P_W]&p_h=[P_H]&mt=[MT]&rwt=[RWT]&wt=[WT]&sdkv=[SDKV]&vol=[VOL]&content_v=[CONTENT_V]&conn=[CONN]&format=[FORMAT_NAMESPACE]_[FORMAT_TYPE]_[FORMAT_SUBTYPE]

Since I cannot use IMA, I have to replace these macros myself. The Google IMA website has not given any guidance as to what these values should be. Some of them, which I suggested by looking at the URLs generated by IMA, but some of them are still missing. See the full list below.

 CPN: BREAK_TYPE: The type of adbreak (1 for preroll) SLOT_POS: Sequence number of the advertisement AD_ID: Advertisement ID, inline-advertisement ID AD_SYS: Advertisement system, inline-advertisement system AD_LEN: AD length in miliseconds P_W: Videoplayers' size width (pixels) P_H: Videoplayers' size height (pixels) MT: RWT: WT: SDKV: SDK Version (so our own version?) VOL: Sound Volume (not 100% sure) CONTENT_V: CONN: FORMAT_NAMESPACE: FORMAT_TYPE: FORMAT_SUBTYPE:

What are the other macro values used by Google IMA?
