MCWS/v1/Playback/Info has no "Status" value

(1/2) > >>

avid:
I don't know if this is a Linux-specific issue. But if start playing a video file then MCWS/v1/Playback/Info does not return a "Status" value:

</Response>

But if I subsquently pause and resume playback, then the field appears:

--- Code: ---<Item Name="Status">Paused</Item>

--- End code ---

I am monitoring this field, partly for display on a remote UI page, but also to track a period of extended inactivity to allow the screen and audio path to be turned off.

I guess I should check the "State" field instead, but this is indicative of a bug IMHO.

Matt:
We're clearing the status for video playback.  I'm investigating more.

mattkhan:
I encountered this when writing my integration with displaycal for video calibration via jrvr

https://github.com/3ll3d00d/displaycal-py3/blob/mcws-untethered/DisplayCAL/mcws.py#L88C9-L88C9

The code to handle it is shown in the link above, it was really messy

Hendrik:
The Status field is not meant to be a replacement for State, but rather offer further details if desired. State is a numeric field and indicates the actual major state of the player. Status contains localized free text, with no guaranteed consistency between playback types - and it being localized makes it practically unusable for scripting anyway, unless you just want to show it to the user.

For clarity, these are the State values:


--- Code: ---enum EPlayerStates
{
PlayerState_Stop = 0,
PlayerState_Pause = 1,
PlayerState_Play = 2,
PlayerState_Wait = 3, (eg. opening)
};

--- End code ---

Thanks for the explanation. I shall switch to using "State" for activity monitoring and use "Status" for display only.
