Description
The app for merging independently coded bistreams into a multiplexed bitstream using differend nuh_layer_id values is outdated.
The main problem is that layers can now share parameter sets, so a simple multiplex is likely to create collisions.
Additional issues:
- NAL unit header syntax is not updated (since an own implementation is used instead of library functions)
- VPS may not contain a proper description of the resulting bistream
- DCI is not filtered
- Start code emulations are not properly handled.
Should the App be removed? Is anybody contributing to fix it?

MR1977 was not referenced here. It provided an improvement for the StreamMergeApp, although the functionality is still very limited. It seems OK to keep the app in this state, so I closed MR 2211.

Note: See TracTickets for help on using tickets.
Since there was no activity on maintaining/fixing StreamMergeApp over the last two years, the broken tool should be removed from the reference software.
