#12922 closed Patch - Bug Fix (fixed)

Patch - ExternalRecorder - Eliminate "No data from external app" message when data returned

An external recorder app, even when it is providing data, can end up logging messages (in my specific case, every few minutes) of the form:

ExternSH recorders/ExternalStreamHandler.cpp:594 (run) - ExternSH(.....): No data from external app

It appears that if an external recorder apps returned data is fully consumed in the stream handler inner loop and that no more data is available in a 100ms interval (which may happen with external recorder apps that either buffer data, or receive a transport stream slowly) the stream handler will increase the counter indicating no data, even when the external recorder app has actually returned data. After 1000 such repeated events, the message is logged.

This patch resets the counter whenever data is returned from the external recorder app.

I am not entirely sure this is the correct fix, but it addresses the specific case I have observed.

Lightly tested with a prototype external recorder app.
