The script has no error handling of its own, so these all pass silently.
- update_lib exited 1 after succeeding, so callers could not chain it
- a failed maixcdk build printed "Build Error!" and exited 0, letting a
caller carry on with no artifacts
- add_to_kvmapp did the same when the source did not exist
- the copies in update_lib were unchecked; since update_lib is what keeps
the SDK components in sync with the source tree, a silent failure there
yields libraries built from stale sources
Move frame ownership and zero-copy VENC handling into the tracked MMF
and Vision sources instead of relying on a preload hook. Keep the sensor
name mapping aligned with middleware enums and release deferred VI frames
safely across encoder lifecycle changes.
OLED sleep settings are stored as seconds, but the kvm_system reader parsed the value into a uint8_t before assigning it to the uint16_t state field. Values above 255 seconds wrapped, so 5 min, 10 min, 30 min, and 1 hour did not behave as selected.
Parse the setting into a uint16_t-sized temporary value and terminate the read buffer before atoi so all configured durations up to 3600 seconds are preserved.
Closes#826
providing oled_sleep_param with a 16-bit value (i.e. >256), results unpredictable display sleep times as only the low 8-bits are retained due to uint8_t (i.e. 5 minutes 300 seconds; shuts off in ~44s / 300s - 256s), this patch switches to uint16_t which should allow for up to sleeps of up to 65535 seconds.
OLED will automatically wake up in the following scenarios:
1. Plug and unplug the network cable
2. Plug and unplug USB
3. WiFi connection status has changed
4. Plug and unplug HDMI
5. HDMI input resolution changes
6. The transmission format has changed
7. Change in transmission quality
Optimize the detection algorithm to reduce the detection time to 3-4ms per frame, using set_frame_detact (xx); Dynamically set the number of detection interval frames
Use a single data packet to replace the SPS + PPS + I three packets retrieval.
Note: This modification may require synchronization support from the server.
After testing, calling the system API still cannot effectively detect the insertion/removal of the ETH cable; modifications were made only to the status retrieval part.
