Hi There is mistake in formula mentioned in datasheet we will correct it soon. While calculating the size, maxWidht is aligned to 64 and maxHeight aligned to 16 for progressive and 32 for interlace.

Hi Charles, We tried to reproduce it in standalone test app, but could not. Can you please migrate to 02.01.00.09 version. You can get encoder from http://software-dl.ti.com/dsps/dsps_public_sw/codecs/DM36x/index_FDS.html link. latest 02.10.xx.xx encoder supports upto 4096x4096 resolution and many...

Veeranna Hanchinal

Hi, You are setting rateControlPreset = IVIDEO_LOW_DELAY, you need to set rateControlPreset = IVIDEO_USER_DEFINED and rcalgo = 5. When you set rateControlPreset other than IVIDEO_USER_DEFINED, rcalgo param will be not be in use. You can have look at http://processors.wiki.ti.com/index.php/DM36x_Rate_Control_Modes...

Veeranna Hanchinal

Hi, In case of rcalgo = 5, there are some params which controls video quality and "cpb_size_value_minus1". In this case 'LBRmaxpicsize' parameter you needs to set proper value, please check userguide for it. Thanks, Veeranna

zack I try rcalgo = 6 , there has no bitrate overshoot . but there has macroblock when sense change vary large You mean to say using rcAlgo = 6 solves your bitrate overshoot problem, but you are observing blockiness during scene change? It may possible because during scene change encoder will generate...
