I have read the Codex and I'm about 3 hours searching around sites for a deep understanding of post-formats but got no answer. Don't know if it is a dumb question but after spending a long time searching I thought here is the best place to get answered.
I'm developing a simple theme that have an option to display the posts on a grid style. It displays the thumbnail and the excerpt and I want to display the video instead of thumbnail, if the selected format is set.
How is that possible?
