[Opensvcdecoder-support] multiple simultaneous OSVC decoders

[Brett S. <bs...@uo...>]

Hello,

In my network simulation, I have an OSVC decoder, which works great.

However, if I have multiple instances of the class, each of which calls the
OSVC library (each running in its own thread, receiving it's own H.264
stream), things start to go wrong. If I disable all but one of the
decoders, so that they packets reaching it are identical, it works every
time. But whenever there are multiple instances of the decoder, after the
first one finishes, the others produce corrupt results, and occasionally
one of the decoders produces corrupt results right from the start.

I'm linking against OpenSVCDec statically. And each decoder
calls SVCDecoder_init with it's own _playerstruct variable. I've tried
omitting the call to SVCDecoder_close, but that has no effect. I
have verified that the binary input into the decoder is the same in either
case, yet it produces different output. The only difference I can see is
having multiple instances or not.

It seemed to work fine with multiple when I was testing with AVC streams,
but once I introduced SVC streams the problems started.

Is this something that should work, or should not work?

Thank you!
