#8629 open enhancement

Allow additional stream specifier when mapping by stream id

Description

Summary of the bug:
Many Blu-ray titles include an AC3 compatibility track in addition to a TrueHD/Atmos one. The problem is that they are identified by the same MPEG-TS PID and there's no way to select one or the other, as you can see below. In fact when using -map i:0x1100 ffmpeg tries to map both of them, while -map i:0x1100:0 gives the following error: Stream map 'i:0x1100:0' matches no streams.. I think a good idea could be to add the ability to specify an additional stream specifier.

How to reproduce:

Why is it a disadvantage to use -map 0:1?

Replying to cehoyos:

Why is it a disadvantage to use -map 0:1?

That the order of the streams is not always known

I noticed I messed up the command in the OP, here it is:

% ffmpeg -y -i sample.m2ts -map i:0x1100 -c copy sample_out.thd

comment:5 by Balling, 3 years ago

But ac3 is a part of TrueHD+Atmos... And is needed to decode EAC3.
