The prev and next steps with a stream of images is still buggy: e.g. the last step can be off by one.

This is an old bug from the old biotracker version: When the tracker is closed with an active video, the said video will be loaded again upon biotracker start with the last frame before closing set as the current frame. When this happened it is not possible to step back in time, instead one needs to "play" and only than can step back.
Todo: check if still happens and if so : fix

Currently the video status stays at "playing" when the video finished playing

It would be nice to be able to press Shift + [the shortcut for framewise video seeking] to override the "tracking enabled" checkbox. This should seek the video without tracking.

Would be nice even when mouse clicking the seek buttons.

When closing the tracker we should remember the current frame position and the video that was used.

In the old biotracker we let the trackers add both tools and params widgets. However, this can be easily be joined together to one widget

TrackingAlgorithms can notify the user about their state using the notifyGUI() functionality. Currently, these messages dont't appear in the BioTracker Notifications widget.

When a stream of images is loaded for the first time, the very first image is aligned wrongly.

should this really be? It should be set to nothing, I suppose.

On windows builds the following error was encountered:
"Unable to open video "
This was due to the ffmpeg dll's being missing. However the error message is very inexplicit about what's wrong. An error in the VideoCapture constructor is being caught and replaced by this.
A more verbose error message should be displayed.

In the windows build, when moving around the video the Biotracker crashes. The crash does not occur instantly, but after moving it randomly for a short while.

a biologist that I work with uses .h264 files, they don't show up in the file open dialog, but after renaming them they open just fine.

please add a . filter for rare filetypes and catch exceptions that might occur when other files are opened

Due to changes that were made to the namespaces in the Core repository we need to adapt some code parts in the GUI. (see: BioroboticsLab/biotracker_core#13)

a biologist that i work with has super long videos and using the seek bar isnt very accurate when searching for certain behaviors. seeking single frames takes too long.

it would be great if one could click in the frame position box and enter the desired frame position.

Make the load of *.tracker.zmq files possible

Dummy issue to upload images to github

Implementation of a settings window to make it easy to change application settings

space: play/pause (implemented already)
q, w: bwd, fwd

more ideas?

When building with cmake we get a namespace conflict:

CPM namespace conflict.

  Conflicting propressor macro: CPM_CMAKECONFIG_NS.
  Our module UNID: _biotracker_core_.
  Conflicting UNID: github_bioroboticslab_cmakeconfig_master.

This seems to be a bug with my docker instance but we should investigate anyway: when replaying a video I get a strange flickering of the tools panel on the right side of the tracker window

Linked with #19

fix

Playing a videofile or playing images in playmode renders the images fast as lightning, but with manual stepping through it sometimes takes long to update and even skips images.

At the moment users may remove gui elements. If this happens by accident, the user will need to remove the CFG file. We should disable the option to remove the core elements (tracker selection, video replay etc).

See: BioroboticsLab/biotracker_core#3

der export des biotrackers muss angepasst werden, Punkt statt Komma zur trennung der dezimalstelle und komma statt semikolon als separator.

On windows the build depends on Cuda 6.0 exact version. This seems to be induced by cereal.

Is it possible to update this to a more recent version? Cuda 6.0 is two major versions behind the current cuda 8.0

Implement the GUI frontend for the core implementation: BioroboticsLab/biotracker_core#90

When a tracker is selected in the combo box we need to load it as current

tbd

Write current frames in bold

Currently it is not possible to set the speed of a video replay

The stop button is currently not implemented

When displaying a live video from webcam it is seekable. However, it does not make any sense to seek this. Seeking forward and backward only changes frame number. If the frame number reaches 9999 the video stops. It should not.
The GUI is very non-intuitive in this aspect.

We changed the functionality of the video slider so that it shows a preview of the current frame the slider is on and it works nicely with small videos that can be played (rendered) fast. However, when using more difficult to render videos this performs really poorly so I would suggest two options:

1.) Build some sort of heuristic to detect weather a video is "difficult to play" or not (imho this should be easy to implement, e.g. measure the first two frames and see how close they get to the expected fps) and then select: if the video is easy to play, use the new fancy technique with previous, otherwise use the old version where the video view does not get updated upon sliding the frames (which looks not that nice but at least does not come with a performance penalty)

2.) Only use the old version where there is no preview of the current frame

Provide some sort of installer for all OS. Following tasks must be managed:

• decide if python/conda should be installed as well

steps to reproduce:

1. load three pictures with three different sizes
2. go from the the smallest image to the middle one
3. go from the biggest image to the middle one
4. now the middle sized image has a different size than in the first run

see https://github.com/BioroboticsLab/biotracker_lucasKanade/issues/20

I used the arrow keys to forward and then rewind the video when an assertion was thrown in VideoControlWidget::previousFrame().

( assert(m_bioTracker.getCurrentFrameNumber() > 0) )

We might provide some sort of gui interface for realtime scripting
