Hi Jean-Paul,

Yes, I understand that I have two independent Mpeg2 streams. I have been involved with broadcast engineering for some time now. I have been using VLC for as long as it has been about and been watching it evolved over that time.

I have been using VLM files for remapping TS PIDs and IP streaming this data to a QPSK modulator for testing. I can see a lot of potential in doing this with VLC in the future when the cost of IP to ASIDVBequipment comes more affordable. I also in the process of designing a low cost IP (UDP) to DVB RF modulator, if I can see any market potential in a product like this.  I will make all my software and setup information available to all here for any possible changes to VLC at future date.  

So I'm passing on any problems I may come across in doing this research and development work. I'm not sure if anyone here has use VLC this way before to build up multiplexed DVBstreams.

Regards
Grant


Hi Grant,

You are aware that you are not constructing a MPTS stream here, but
merely sending out 2 independent MPEG-TS streams (aka SPTS)?

The last comma, should not be there.

idem

I will comment on the working later when I actually done some testing.

Kind regards,
