Compression mode in m2ts (with TrueHD) is not detected correctly

Oops, fixed, for next version.

almirus commented 3 years ago

@JeromeMartinez please also pay attention to the Stream size, it it also incorrect, must be larger

JeromeMartinez commented 3 years ago

True, I reopen the ticket for the bitrate part, will be longer to implement (not sure about how I'll show that, I know the core bitrate but I don't know the global bitrate due to TS which does not store such info, I need to reorganize a lot of code for a good and generic handling of such kind of stream)

almirus commented 3 years ago

@JeromeMartinez TrueHD havent the core... i could be wrong, but the container holds two different streams: AC3 (640kbps) and TrueHD (8Mbps)

havent the core

It has a core. It is just not needed for TrueHD, it is needed for EAC3 dependent stream.

"core" is when it is an part of sound file (trueHD) like a DTSHD, but here is two different file

almirus commented 3 years ago

No, AC3 (if it present) and TRUEHD is different files, not part of each other But DTS is part of DTSHD (one stream) https://en.wikipedia.org/wiki/Dolby_TrueHD#Blu-ray_Disc

once again image

your test file have two different (independent) stream TrueHD and AC3 (physically in one file TrueHDAC3.thd​), typical for Blu-ray Rip for example my file haven't ac3 stream

almirus commented 3 years ago

it's not core, it is sub (different) stream TrueHD doesn't contain AC3 stream
