MPEG2/PS with VBI data?

[intel6]

Hi,

I'm trying to write VBI data into an MPEG2/PS stream - but it seems to have problems initializing the muxer. Specifically, when trying to initialize the chunk writer for the VBI stream (in umc_mpeg2_muxer.cpp:490, MPEG2Muxer::Init) it references a PMTTableWriter which is not initialized in that case.

Is this unsupported by the MPEG2 standard, or not yet implemented in the UMC 5.2 libs?

Thanks,
Tilman.

Hello Tilman,

there is comment from our expert:

1) VBI data could be written into MPEG2/TS stream only. (No failure for VBI+MPEG2PS is an issue which should be fixed in the next version of IPP media sample)

2) VBI presents in the source code but is not fully supported yet (and is not mentioned insample documentation). So you can extend this but please do not rely on VBI support implementation completeness in this version.

Regards,
Vladmir
