Add explicit timing and timeout policy controls so aravissrc can wait for sparse or triggered image streams without treating every empty buffer pop as a fatal error. Keep fixed-rate behavior as the default, skip framerate caps/latency reporting for sparse timing, and allow GstBaseSrc unlock to interrupt waits cleanly.

Hi, Thanks for the patch. Could you provide some gstreamer pipeline examples that exhibit the problems this work fixes ? It'll help me review the changes. Thanks. |

Add sparse stream handling for aravissrc
This adds explicit timing and timeout policy controls so aravissrc can wait for sparse or triggered image streams without treating every empty buffer pop as a fatal error.
For triggered cameras, it is valid that no frame is available for some time. In that case the stream can still be healthy, so this change allows aravissrc to keep waiting when requested.
The existing fixed-rate behavior stays the default. Sparse timing skips fixed framerate caps and latency reporting, and GstBaseSrc unlock can interrupt waits cleanly.
Tested:
aravissrcthrough GStreamer with a Basler a2A1920-51gcBAS camera in triggered/sparse acquisition mode.
