Hi guys,

I've seen a few questions on this, but I couldn't find a definitive answer..
.

When using VP6 encoded video with progressive download, metaData (for height
, width) etc is retrived fine.

However, when streaming through FCS, not only do I not seem to get any metaD
ata, the onMetaData function doesn't even fire... is this somethign well kno
wn or have I had my head under a rock?

If there is a problem with FCS sending metadata, does FCS at least *read* me
tadata.. so I could extract it on the server end and send it to the client?

Any thoughts greatly appreciated.

Dave

PS. On a side note, has anyone experienced slight audio glitches when stream
ing VP6? Every now and then a little high pitched squeek? They are not prese
nt when playing it locally.. so it's not an encoding issue.

Dave,

Have your tried using Buraks' Metadata Injector? I've used it, and f
it's the best metadata tool I've seen for FLV files, and I've used it
for both PDs and streaming FCS. The best part is that it's free:

Hi Bill,

I did think about that.. but things like width and height etc should be pres
ent in the VP6 file already...  indeed they are if the file is PD'ed but as 
soon as the same file is used via FCS (1.5) my onMetaData function doesn't f
ire any more..

This is only a problem as we've just started using VP6... it was ok before (
i think..)

Best,

Dave

Definitly upgrade to FCS 1.5.2 if you haven't already.

Dave,

Let me give it a spin on FMS2 and see if it works w/o any injection.
A couple years ago I worked extensively w/ metadata for MM, and while
I ran into some problems, I didn't experience the ones you
mention, ...but they weren't set up using VP6 then.

I'll get back to you later this morning.

Hi Stephan,

Upgraded as you suggested.

And no, looping through the contents of onMetaData shows nothing.. and traci
ng out something like "I've been called!" at the beginning of  onMetaData sh
ows nothing... hence, i'm pretty sure the problem is that the stream is just
 never getting called.

However, there is potentially one piece of information I've left out... The 
server actaully publishes the stream (from local file) and then all other li
steners tune into the stream, so this way it is possible to to TV-style deli
very of a program. Is it po
ssible that the stream the subscribers are listening to does not have metada
ta in, as the metadata is not inject from the file by the server?

Thanks for all the advice so far..

Cheers,
Dave

Bingo,
That's probably it.

onMetadata fires at the very beginning of a stream. If you tune into an
existing live stream (or indeed a pseudo-live stream as you describe - I
assume that's a serverside stream) then there is no way of firing onmetadata
again as the beginning is over so to speak.

You have several choices from here:
- capture onmetadata serverside when you start up the stream, save to a
SharedObject and work on the client from that
- depending on what metadata info you need you can let the server tell you
the total duration. The height and width can be figured out without
metadata. Maybe you are familiar with that. If not then post again.

Hi Stephan,

Yeah, looking back through all my old code (and looking at my comments!) I r
ealized i have alwasy had this problem.....

The way I got around it was to have a checkAspect() function which was calle
d on a timer.  This made sure that my video display window was the right siz
e for the stream, and centered it in the viewing area etc etc.  However, wit
h VP6 video, sometimes the
width and height of the stream comes back as 0, and I have no idea why.  It 
seems compltely random... I enabled my old debug traces, to tell me what hei
ght it was trying to set to.. and about 1 in 5 plays of the stream it just g
ets a stream width/height o
f 0,0 and never recovers.

This, interestingly, is new behaviour after using VP6.  All the old video us
ing MX flv is absolutely fine - works every time.

I also can't just check the values at onBufferFull becuase the server can po
tentially stream several files (of different aspect ratios) one after anothe
r, and so you can see the mistake there..

Perhaps a shared object is the answer... and the server simply writes the us
eful metadata into it everytime it reads a new file.

Please let me know if I have missed anything in a method to get size in anot
her way.

Cheers,
Dave

Bingo,
That's probably it.

onMetadata fires at the very beginning of a stream. If you tune into an
existing live stream (or indeed a pseudo-live stream as you describe - I
assume that's a serverside stream) then there is no way of firing onmetadata
again as the beginning is over so to speak.

You have several choices from here:
- capture onmetadata serverside when you start up the stream, save to a
SharedObject and work on the client from that
- depending on what metadata info you need you can let the server tell you
the total duration. The height and width can be figured out without
metadata. Maybe you are familiar with that. If not then post again.
