* fix: operator precedence bug in detection type check
The condition:
topic == DetectionTypeEnum.api.value or DetectionTypeEnum.lpr.value
evaluates as:
(topic == DetectionTypeEnum.api.value) or (DetectionTypeEnum.lpr.value)
Since DetectionTypeEnum.lpr.value is a non-empty string (truthy), the
second operand is always True regardless of topic. The intended check
is whether topic matches either enum value:
topic == DetectionTypeEnum.api.value or topic == DetectionTypeEnum.lpr.value
* fix: apply same or operator fix to review/maintainer.py
Same issue as record/maintainer.py — the condition was always true
because the bare enum value is truthy.
* style: ruff format record/maintainer.py
* fix: check HTTP response status before parsing JSON body
upload_image() calls r.json() before checking r.ok. If the server
returns an error response (401, 500, etc) with a non-JSON body,
this raises a confusing JSONDecodeError instead of the intended
'Unable to get signed urls' error message.
Move the r.ok check before the r.json() call.
* style: remove extra blank line for ruff
The name parameter was interpolated directly into the SQL query via
f-string, allowing SQL injection through crafted face name values.
Use a parameterized query with ? placeholder instead.
parse_preset_input() uses input[len(_user_agent_args) + 1] to find
the FPS placeholder, but preset-http-jpeg-generic does not include
_user_agent_args at the start of its list (only preset-http-mjpeg-generic
does). The FPS placeholder '{}' is at index 1, not index 3.
This means the detect_fps value overwrites '-1' (the stream_loop
argument) instead of the '{}' FPS placeholder, so the preset always
uses the literal string '{}' as the framerate.
When hwaccel_args is a list (not a preset string), the fallback in
parse_preset_hardware_acceleration_encode() calls
arg_map["default"].format(input, output) with only 2 positional args.
But PRESETS_HW_ACCEL_ENCODE_BIRDSEYE["default"] contains {0}, {1}, {2}
expecting ffmpeg_path as the first arg.
This causes IndexError: Replacement index 2 out of range for size 2
which crashes create_config.py on every go2rtc start, taking down
all camera streams.
Pass ffmpeg_path as the first argument to match the preset template.
In both expire_snapshots() and expire_clips(), the expired_events
query uses .iterator() for lazy evaluation, but the very next line
calls list(expired_events) inside an f-string for debug logging.
This consumes the entire iterator, so the subsequent for loop that
deletes media files from disk iterates over an exhausted iterator
and processes zero events.
Snapshots and clips for removed cameras are never deleted from disk,
causing gradual disk space exhaustion.
Materialize the iterator into a list before logging so both the
debug message and the cleanup loop use the same data.
The cosine similarity calculation is guarded by:
if not np.any(np.linalg.norm(velocities, axis=1))
This enters the block when ALL velocity norms are zero, then divides
by those zero norms. The condition should check that all norms are
non-zero before computing cosine similarity:
if np.all(np.linalg.norm(velocities, axis=1))
Also fixes debug log that shows average_velocity[0] for both x and y
velocity components (second should be average_velocity[1]).
cv2.imread with IMREAD_UNCHANGED loads the image as-is, but the code
unconditionally indexes channel 3 (birdseye_logo[:, :, 3]) assuming
RGBA format. This crashes with IndexError for:
- Grayscale PNGs (2D array, no channel dimension)
- RGB PNGs without alpha (3 channels, no index 3)
- Fully transparent PNGs saved as grayscale+alpha (2 channels)
Handle all image formats:
- 2D (grayscale): use directly as luminance
- 4+ channels (RGBA): extract alpha channel (existing behavior)
- 3 channels (RGB/BGR): convert to grayscale
Also fixes the shape[0]/shape[1] swap in the array slice that breaks
non-square images (related to #6802, #7863).
In BirdsEyeFrameManager.update(), the exception handler on line 756
resets self.active_cameras to [] (a list), but it is initialized as
set() and compared as a set throughout the rest of the code.
Since set() \!= [] evaluates to True even though both are empty, the
next call to update_frame() will incorrectly detect a layout change
and trigger an unnecessary frame rebuild after every exception.
escape_special_characters() returns a ValueError object instead of
raising it when the input path exceeds 1000 characters. The exception
object gets used as a string downstream instead of triggering error
handling.
gpu <= len(self._valid_gpus) should be gpu < len(self._valid_gpus).
The list is zero-indexed, so requesting gpu index equal to the list
length causes an IndexError. For example, with 2 valid GPUs (indices
0 and 1), requesting gpu=2 passes the check (2 <= 2) but
self._valid_gpus[2] is out of bounds.
asyncio.SubprocessError does not exist — Python's asyncio module has no
such class. The correct exception is subprocess.SubprocessError, which
is available via the existing `import subprocess as sp` alias already
present in this file.
The invalid exception reference causes the except clause to raise a
NameError rather than catching the intended exception.

The old code built Date[] arrays with a TZDate object for every day in recording history (365+ timezone-aware date constructions). react-day-picker then did O(visible × history) date comparisons to match each of the displayed days against these arrays. Now we build Set<string> from the raw keys (zero date construction), and pass matcher functions that do O(1) Set.has() lookups. react-day-picker only calls these for visible days
* clean up
* fix environment_vars timing bug for EnvString substitution
FRIGATE_ENV_VARS is populated at module import time but was never

* dynamic ffmpeg
* ensure previews dir exists
when ffmpeg processes restart, there's a brief window where the preview frame generation pipeline is torn down and restarted. before these changes, ffmpeg only restarted on crash/stall recovery or full Frigate restart. Now that ffmpeg restarts happen on-demand via config changes, there's a higher chance a frontend request hits the preview_mp4 or preview_gif endpoints during that brief restart window when the directory might not exist yet. The existing os.listdir() call would throw FileNotFoundError without a directory existence check. this fix just checks if the directory exists and returns 404 if not, exactly how preview_thumbnail already handles the same scenario a few lines below

When ensure_torch_dependencies() installs torch/torchvision via pip, it can upgrade setuptools to >=81.0.0, which removed the pkg_resources module. rknn-toolkit2 depends on pkg_resources internally, so subsequent RKNN conversion fails with No module named 'pkg_resources'.

The fallback to tensorflow was established back in 2023, because we could
not provide tflite-runtime downstream in nixpkgs.
By now we have ai-edge-litert available, which is the successor to the
tflite-runtime. It still provides the same entrypoints as tflite-runtime
and functionality has been verified in multiple deployments for the last
two weeks.
The psutil library reads the process commandline as by opening
/proc/pid/cmdline which returns a buffer that is larger than just the
program cmdline due to rounded memory allocation sizes.
That means that if the library does not detect a Null-terminated string
it keeps appending empty strings which add up as whitespaces when joined.
* - API created events will be alerts OR detections, depending on the event label, defaulting to alerts
- Indefinite API events will extend the recording segment until those events are ended
- API event start time is the actual start time, instead of having a pre-buffer of record.event_pre_capture
* Instead of checking for indefinite events on a camera before deciding if we should end the segment, only update last_detection_time and last_alert_time if frame_time is greater, which should have the same effect
* Add the ability to set a pre_capture number of seconds when creating a manual event via the API. Default behavior unchanged
* Remove unnecessary _publish_segment_start() call
* Formatting
* handle last_alert_time or last_detection_time being None when checking them against the frame_time

* use latest preview frame for latest image when camera is offline
* remove frame extraction logic

The original implementation did a full directory tree walk to find and remove
empty directories, so this implementation should remove the parents as well,
like the original did.
The previous empty directory cleanup did a full recursive directory
walk, which can be extremely slow. This new implementation only removes
directories which have a chance of being empty due to a recent file
deletion.
