After trying many stream capture apps I discovered that 2 would capture the RTMP live stream that I wanted to record. Replay Media Capture (RMC) and FLV Recorder (FLV R). I decided on FLV R for the following reasons.
Replay Media Catcher:
RMC required a FLV timestamp increment setting so that the speed of the recording would be accurate. This required additional work (tinkering) and the Flash recording was still not the proper speed half of the time.
RMC caused my utorrent app to crash every time it started so I could not run my utorrent when I was recording.
I could not play the Flash stream in my browser while I was capturing. (The website only allowed one connection to the server at a time).
When I clicked the "Stop recording" button it would not stop the recording. The only way I could stop the recording is to right click it and choose "cancel and save transfer". Once the recording was stopped the only way I could remove it from the list is to close the app. The choices of "Clear all finished" and Clear all Failed" did not clear it.
RMC did not have an integrated FLV player.
In general it was quite a buggy app. Version: 2.01.00.00 Build Date: Mar 22 2007
FLV Recorder:
FLV Recorder has very few options or settings but it did work quite well for my needs.
The main window has a tab for active recordings and separate tab for saved recordings so you can flip back and forth and play a saved recording on the integrated Flash player while you are recording another stream. More importantly the recordings were all good quality and I could view the Flash stream in my web browser while it was being recorded.
The integrated Flash player is convenient but it is a little buggy. When I choose "full screen" the video size doesn't change but the rest of my screen is filled with black and I can't get back to the original size so I have to do an "alt F4" to close the player window.
One annoyance I have with both apps is that they do not show the URL of the stream. RMC will show part of it when you right click the stream in the list and choose "properties" but it does not give the complete URL - it sort of chops it off. FLV R does not show any part of the URL and I could not find an option to show it. The apps must have the URL if they are capturing the stream so why don't they allow you to view or copy the URL.
FLV R is superior to RMC but both apps require some work to fix these problems I encountered.
