[Mp4-tech] H.264 Long term reference frame

Mayank,
I went through that process rather painfully and I'm not done yet. My
advice would be to debug some conformant H.264 bitstreams (their names
start with MR letters), you can download from ITU or MPEG sites and then
try to learn more about how these bitstreams are using MMCO operations
(dump_dpb() is very helpful)
Best regards,
Andrew

Subject: [Mp4-tech] H.264 Long term reference frame
Dear List members,
I am using JM 9.6 encoder_baseline.cfg encoder. I wanted to use long
term reference (LTR) frame. I can see that it is implemented in this
version of software but is not enabled. I tried to enable it in various
ways but with no success. I couldn't find anything in the archieves
regarding LTR referencing. Can anybody help me in this regard? 
Regards,
Mayank
