I have a membership website which teaches how to play a musical instrument on video. Often the viewer (student) will need to constantly repeat a section to keep practicing that part correctly. I have jw player embedded on my site.
I need three primary goals to be met:
1) user is able to press 'a' and 'b' on their keyboard which sets their desirable start and stop loop section in the video clip. They can press 'x' to remove those points so the video continues playing normally. (You can go to a similar site to see this in action - GuitarTricks com) However, in my opinion they haven't done a great job, because the viewer sees the letter A & B on the track and they are extremely large and it's hard to set shorter exact points. They also have an unnecessary 'r' button which puts it on repeat, but if you set 'a' and 'b' then obviously you want it on repeat - if not just press 'x' to remove it. They have an unnecessary button to click on the video for loop, which I don't think we need, because again, if you set 'a' and 'b' then obviously you want it on repeat.
