Streamable embeds now possible. For now, it's complicated, unfortunately. Here are the steps.
1. Click embed on the Streamable video.
2. Paste the embed code.
3. Extract the video's ID. What you're looking for is XXXX/XXXXXX format. For example:
Code:
div style="width: 100%; height: 0px; position: relative; padding-bottom: 178.218%;" iframe src="https://streamable.com/s/7apdg/vspjpg" frameborder="0" width="100%" height="100%" allowfullscreen style="width: 100%; height: 100%; position: absolute;" /iframe></div
4. Wrap the video's ID. For example:
[streamable]7apdg/fsklhc[/streamable]
Result:
