Any tips would be much appreciated. Thanks. Wessel I tried this and it all seemed to work first time:

However, when I click ‘1X’ (or any of the other buttons) to view the stream, the flash players comes up, but never gets past the ’spinning wheel’.

Any tips would be much appreciated.
Thanks.

Replacing it with the modified one supplied results in a corrupt reocrdings page in mythweb, but looking at the code in recorded.php it isn't the same as tose mentioned here, so I can't work out the format or where to put code to enable the flash encode / stream links. Using the supplied recorded.php does allow me to encode the flash file though, so the underlying mechanisms are lla working (the flv fiels are created OK etc. So near yet so far - anyone have any ideas?

If you stop the video, the FFmpeg job continues on, etc.. For Mac OS X, Linux and Windows based boxes, what's really needed is an option in MythWeb to launch VLC (in streaming mode) on the back-end and then launch either VLC, mplayer or WindowsMedia on the front-end to playback the stream. (The advantage of using VLC on the client side too is that you can forward-fast/rewind the stream.) Longer term, the flash video player could be hacked to simply display the RTP-over-HTTP stream from the VLC server and to control it using the VLC server's built-in mini-webserver.

They are several versions behind the latest versions of ffmpeg. The errors you encountered above is because ffmpeg failed, not the ruby program. Do this to grab the latest version and install it into /usr/local: svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg Then update the mythflash script to use the compiled version until your linux distribution updates its ffmpeg package in the future.

If I try to encode a large file (this one is 3.99gb) from command line using the ffmpeg script command, ffmpeg reports time increasing, but frame, fps, etc all stay at 0.. I am going to let it run and see how long it runs unless thats indefinitely. Update.
