Recording H.264 Live Stream on the Server

I have seen several questions which were close to what I am looking for, but haven't found an answer that worked. I work at a school, and we use a NewTek TriCaster to stream live events through FMS 3.5, which I am hoping to upgrade to AMS 5 to allow HLS. We have been streaming a single H.264 encoded feed through the server as a live stream which works well. They have recently asked if it is possible to archive that recording on the server. I was able to get everything to work correctly when I switched to using the VP6 codec, but as long as we were streaming with H.264, I could not get the server to record it correctly. Here's what I have tried:

This code works for the VP6, but the H.264 doesn't record the video:

application.onPublish = function (clientObj, streamObj)

{

     var s = new Stream("archive");

     s.record();

     s.play(streamObj.name);

}

This worked and created an flv file, but caused a few other issues due to the encoding of the VP6 and having to re-encode the video to H.264 before putting the file online.

Based on suggestions I was reading, I tried this with the H.264 stream:

application.onPublish = function (clientObj, streamObj)

{

     var s = new Stream("mp4:archive.f4v");

     s.record();

     s.play(streamObj.name);

}

This created an f4v file, but I could not play it. When I tried to open it in Adobe Media Encoder, it gave an error that it did not support the compression type.

Thanks.
