Unable to decode "BL@L3" and "LC@L3, BL@L3" format profile? about libmpegh

[SakethSathuvalli]

Hi @sclsj,

Can You please let us know if the decode failure happens with our latest commit - 3b23f65 ?

Thanks!

Hi @sclsj,

I was wondering if You got a chance to try decoding the files with our latest commit!

[sclsj]

Yep, still the same problem (error output) with freshly cloned and built project.

With that being said, I'm doing autoreconf -i ; ./configure; make to build the project. It seems like I can also build the project using cmake (which I tried; it gave an error, see below) or the makefile in build/make (which I tried before successfully, but I don't remember how I did it)? Is there any difference between these three way of compiling?

Cmake error (`mkdir buildnew ; cd buildnew ; cmake ../)

Hi @sclsj,

We follwed the steps provided here and the build was successful on macOS. Can You provide details about Cmake version you used and the compiler you are using ?

Got the same error with make.

Apparently by commenting out that line (55) the program is able to compile. I'm not sure if that causes any unexpected behaviors, but it seems like the executable works and passed the smoke test provided.

[sclsj]

Hello.

For your reference, I cloned the latest repo and compiled again using autoreconf and saw no errors.

[sclsj]

Hello, this issue might be a duplicate of #54. Let me know if I should close this issue.

[SakethSathuvalli]

Hi @sclsj,

The fix for #54 is available on latest main now. Please try latest main build once.

Thanks!

Closing due to no activity since long time.
