I think you are having problems on multiple fronts:

1) You can’t just mix Flex 3 and 4 code – if you want to use the code sample in FB4 you will have most likely have to do some converting of components.

2) The JSON functions I use are in an open source Adobe Extension Library called CoreLib.

3) VideoList is a repeater component I externalized for the sample code as it was not important for the topic of the sample.

4) crossdomain.xml files are an important principle of Flash security that was introduced by Adobe quite some time ago. I recommend you read up on this topic on Adobe LiveDocs.

5) The Flex App is loaded into the player through the BEML Template code. As I mentioned, you need to have access to a Brightcove account with the facility to create player templates in BEML yourself for this sample.

HTH

i have write you private message on your brightcove account.
sorry but i don’t have experience with Flex application. When you have time could you help me?

If you have a email address, i send you my flex project.

i have 3 problems. i use abobe flash builder 4 (trial)

1) When i copy yor script in my page ( mxml ) i have a error

1120: Access of undefined property JSON. BCSearch3.mxml /BCSearch3/src line 128 Flex Problem

1046: Type was not found or was not a compile-time constant: VideoList. BCSearch3.mxml /BCSearch3/src line 397 Flex Problem

2) i dont’ know cross domain. I must create a another file or class with code? which is the extension? I insert in src/default package ?

3) what is the connection between player and Flex application?

this search work on my account is correct? no in my defined player.

p.s Sorry for my english.

all the code is listed above – note: you will need access to a Brightcove account with API access to implement this not just Flex.

Thank you very much
