export time variation (animations)

[rgetz]

There are ways to export png in the instruments, but sometimes - it's the time variation that is more important for documentation/labs.

In this case - export to animation would be required.

Some pointers can be found : http://www.ifnamemain.com/posts/2014/Jul/11/screen_capture_1/

doing it a similar way (and including the ffmpeg library) would allow animated png or gif (which is what most people have asked for). I am not a lawyer, and don't want to talk to them about this - so we should stay away from things fraught with danger, like H264, and other potentially patented video codecs in the binaries that we distribute.

We can currently save a buffer as a CSV file. What about saving multiple buffers to the csv file and replaying them in a similar fashion to the reference waveform? (this would also be useful for demo mode). This way we would have access to the actual data, as well as use Scopy as a rendering platform instead of relying on video encoding libraries (which shouldn't really be a dependency for our application).
The user specifies number of buffers/seconds to capture. Multiple channels can be saved at once as well, and people can use different scaling/zooming to view the waveforms.
If people want to make .gifs/.mp4s out of the waveforms, they can always use 3rd party software.
