What is supported profiles of H264 in sample code

Hi,

Could the H264 sample codes of IPP support the base or high profile?

In the sample codes, SetSequenceParameters class said that

// We don't meet any of these contraints yet
m_SeqParamSet.constraint_set0_flag = 0;
m_SeqParamSet.constraint_set1_flag = 1;
m_SeqParamSet.constraint_set2_flag = 0;
m_SeqParamSet.constraint_set3_flag = 0;

I had understand that these indicate that these codes supported only main profile.

However, when I changed the variable 'profile_idc ' of H264EncoderParams class into other profile, such as base profile,

the encoding process is succeed. If I use the component allowed other profile, these sample code could use other profiile?

And I had heard that the sample code used only number of slice is 1. Is thie right?

Please let me know that these ideasare right.

Regards,

TG

Hello,

yes, IPP H.264 encoder should support all profiles. There are some known limitations, please consult with codec's readme.htm file for details.
