Re: [Opensvcdecoder-support] multiple simultaneous OSVC decoders

[Mickaël R. <Mic...@in...>]

We tried multiple instance with ffdshowttryout and it was working for us. 
It is still possible to have a bug somewhere with a shard variable between instances.

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 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.
