save changes by writing them out to the file, and notifying the listener cb if there is any

returns true if s1 contains s2

size of the NALU data with 0001 prefix

Converts both strings to uppercase, then checks if s1 contains s2 (we can find s2 in s1). Returns true if (after uppercase) s1 contains s2, false othe

SW encoding is slow, but should work on all platforms (at least for low resolutions/framerate(s) ) Note that not every sw encoder accepts every type o

pointer to the NALU data with 0001 prefix

Returns the corresponding Wi-Fi Channel if there is one since the mavlink setting is an int, this might not always be possible (and the frequency is t

Converts both strings to uppercase, then checks if s1 has exactly the same content as s2

BLocks up to X seconds, but should never block more than that

v4l2 h264 encoder on raspberry pi we configure the v4l2 h264 encoder by using the extra controls We want constant bitrate (e.g. what the user has set)

weather this channel is used by openhd or not.

* It is more efficient to aggregate / keep mavlink messages in chunks instead * of using a wb packet for each of them - Aggregates the given mavlink

Helper function to retrieve IP addresses starting with a specific prefix

returns true if this parameter needs the extended parameters' protocol (which is the case when its value is represented by a string)

Interface, telemetry and video each have their own directory for settings to separate them logically like also done in code

Helper for development - we catch 2 things with the following pattern: 1) When openhd is started - check if the file exists, in which case either a de
