Dynamic Playlist with XML generated thumnails
|
|
|
|
I've been working with the newly updated Lisa Larsen article in the
FMS Dev Center. She gives an example of generating a playlist
dynamically with and XML file and custom component. I'm trying to
take this and adapt it to a site I'm currently working on. The
problem is is that it only seems to work half the time. That is, the
thumbnails only render one out of every three four times and they're
all inconsistent. It also seems that the thing is causing FMS to
crash sometimes. When I point the XML file to my local streams, it
seems to jam up and stop delivering any stream, even though the
console says it's working fine. Does anyone have any experience with this?
thanks guys

| We have been trying to use it for a piece we are doing as well and have
run into some problems.
The first issue was that it was opening 5 connections automatically per
user and then fluctuated between 6 and 7 connections when playing back
the video.
After awhile the connections on the video clips would drop out
unexpectedly (similar to what someone was reporting earlier).
We removed the thumbnail functionality and that cleaned up our number of
connections, but we are still experiencing connections dropping suddenly
on vide clips.
Any suggestions on what might be happening would be appreciated. I have
not yet gotten around to checking the log files but will do so this
week.
The original article is here.

| I played with that example a while back and found it buggy as well. I
don't remember all the details, but some of the stuff I recall was:
* adding a NetConnection onStatus handler (really a must for any
FMS app, you'll never figure out what's happening otherwise)
=09
* adding trace() statements in the onStatus events for streams
as well as the new NetConnection handler.
=09
* cleaning up some really odd ActionScript (like the
ns.connect() call, an non-existing function)
* adding a "snapshottime" attribute to the file XML, as the
start frame of most videos is a pretty useless thumbnail (how many black
screens or copyright notices do you want to see?)
I think the overall concept of that example is good, but I have to admit
I was disappointed at the quality of the code, lack of testing and how
unreliable the app ran. Our examples and technical articles should work
better.
I sorry but I can't post the fixed source as it's morphed into another
project and would take too much time to extract.

| Sorry I can't help with the dynamic thumbnail part. We opted to make thumbnails manually. However I might know what's happening with the video clips dropping out unexpectedly.
It took some digging into Macromeida's FLV Playback code to figure this out. Under the hood, the FLV Playback component creates an instance of a video player object each time you ask it to play a new video. It seams that the component does not do a good
job of making sure responses from the server only affect the associated video. So what happens is if you switch to a new video before it ends when that previous video stops playing it also stops playing any current video that might be playing. Maybe th
is is what is happening in your case. If it is here is how I fixed it...
// Note: I have a n instance of an FLVPlayback component named "player"
private function _playVideo(url:String) {
// Before we start playing a new video, first delete the current video object
// Note: you can't delete the default video object that resides at index 0
// Also I start the player using index 1 so that the one at 0 never interferes
if (player.activeVideoPlayerIndex > 0) {
player.closeVideoPlayer(player.activeVideoPlayerIndex);
delete player.getVideoPlayer(player.activeVideoPlayerIndex);
}
// Set a new video player index and make it the active and visible video player object
// Note: in my class i have a field to keep track of the index (nextVPIndex)
player.activeVideoPlayerIndex = ++nextVpIndex;
player.visibleVideoPlayerIndex = nextVpIndex;
//Now we can play the next video
player.play(url);
}
Hope that helps,
Steve
