Although not FLV, I wrote a sample AMF 0/AMF 3 client based on flash.utils.ByteArray and flash.net.URLLoader. See my blog entry http://blogs.adobe.com/pfarland/2008/06/using_amf_with_flashneturlload.html which mentions the ActionScript source which was submitted to BlazeDS as an attachment to BLZ-209. See amf.zip at: https://bugs.adobe.com/jira/browse/BLZ-209
For FLV, the key is to understand the Type column for each field. I took a quick look at the spec and it seems to use conventions similar to the SWF format. private function onComplete(e:Event):void { var ba:ByteArray = loader.data as ByteArray; if (ba != null && ba.length > 9) { // Peek at the first 3 bytes to check for 'F' 'L' 'V' if (ba.readUnsignedByte() == 0x46 && ba.readUnsignedByte() == 0x4C && ba.readUnsignedByte() == 0x56) { ba.position = 0; decodeFLV(ba); } } } i.e. For UI8, use readUnsignedByte() to get a uint For UB[n], use readUnsignedByte() and then shift to find the relevant bit(s) for each flag. For UI32, use readUnsignedInt() to get a uint For UI24, use 3 successive readUnsignedBytes() and shift values appropriately to form a uint from the 24bits. etc...

Yes I have seen that, but there is noting similar for what I want, that is to read the flv content to get its tags according to FLV spec from http://www.adobe.com/devnet/flv/. Pete, that is a good starting point, thank you. However, I need more help to be able to "read" the data from the FLV. readByte() returns an int and readBytes expects at least one parameter of type ByteArray which I have no clue what to put in there. And readObject(0 throws an ouf of bounds error.
