      Fix for #647. · 4b07086f
      Bryant Mairs authored
      In the logplayer, the data stream is read ahead for messages, which is used to determine the size of the output bytearrays. Previously, this wasn't done correctly resulting in non-ideal behavior. Now, the next message is scanned properly, so the only bytearrays that are emitted from QGCMAVLinkLogPlayer are MAVLink messages in their entirety. This also has the benefit of skipping invalid/corrupted messages in the log that's being played back.

      QGC data logging now records small MAVLink messages. · 321f21f2
      Bryant Mairs authored
      Previously MAVLink data streams recorded by QGC would use a fixed block size of the maximum MAVLink message length and fill in only the bytes written by the message. This wasted space, make manual parsing difficult, and broke compatibility with scripts provided in the MAVLink project (issue #174).
      
      This patch alters logging to output only a packed data stream (64-bit big endian unix timestamp in microseconds since epoch + MAVLink message) instead of the unpacked data stream previously output. Additionally the previous logging code used the system endianness for packing in the timestamp, this has now been switched to always be big endian regardless of platform. All the documentation specifies big endian, so the code now follows the docs here.
      
      Additionally data playback has been modified to playback both the new packed data streams as well as the old data streams, even those with improper endianness for their timestamps.
      
      Finally, a variety of bugs have been fixed, along with some additional features and user experience changes, hopefully for the better. All existing functionality has been preserved as well.
