Some mpegh conformance streams fail to decode about libmpegh

Hi @miartad ,

Thanks for trying our decoder! Please find below details about the decode failures You are observing.

File Name	Cause for decode failure
O20_3_FD.mhas	This is a MPEG-H profile level 4 stream. Our decoder supports only upto profile level 3.
C2_5_FD_Tcc-2.mhas	This is a MPEG-H high profile file. Our decoder does not support MPEG-H high profile.
C104_5_FD_Tcc-0-1-2-2-1.mhas	This is a MPEG-H high profile file. Our decoder does not support MPEG-H high profile.
C6_0_FD.mhas	MPEG-H Low complexity profile level 3 decoder does not have support for sampling frequencies above 48kHz
C6_1_FD.mhas	MPEG-H Low complexity profile level 3 decoder does not have support for sampling frequencies above 48kHz
O24_3_FD.mhas	This is a MPEG-H profile level 4 stream. Our decoder supports only upto profile level 3.
C6_2_FD.mhas	MPEG-H Low complexity profile level 3 decoder does not have support for sampling frequencies above 48kHz
C2_5_FD_Tcc-1.mhas	This is a MPEG-H high profile file. Our decoder supports MPEG-H low complexity profile.
C104_3_FD.mhas	The decoder fails to decode as cicp index of this stream represents any setup.
C6_34_FD.mhas	MPEG-H Low complexity profile level 3 decoder does not have support for sampling frequencies above 48kHz
C0_3_FD.mhas	The decoder fails to decode as cicp index of this stream represents any setup.

The streams C104_3_FD.mhas and C0_3_FD.mhas may be expected to be decoded. We will check this and add support for these.
The cause for decode failure of the rest of the streams appear to be in-line with the specification for MPEG-H low complexity profile level 3, and baseline profile level 4 decoder.

Thanks!

Hi @miartad ,

The latest master - e6ebfaa - has fix for the decode failure of C104_3_FD and C0_3_FD files.

Thanks!

thanks a lot, I will check it out!

[amiartus]

confirmed both files decode and play after the patch, thanks!
