    <title>topic MPEG encoder parameter - VideoPacketLength in Intel® Integrated Performance Primitives</title>
    <link>https://community.intel.com/t5/Intel-Integrated-Performance/MPEG-encoder-parameter-VideoPacketLength/m-p/862496#M7912</link>
    <description>&lt;P&gt;Hi experts,&lt;/P&gt;
&lt;P&gt;I am using the ippVideoEncoderMPEG4::EncodeSlice&lt;/P&gt;
&lt;P&gt;function to encode , my purpose is to encode then packetize using RFC 3016 for MPEG packetization.&lt;/P&gt;
&lt;P&gt;I see that whenever the number of encoded bits for a VOP becomes greater than the Video packet length, the macro blocks are marked as invalid for prediction.&lt;/P&gt;
&lt;P&gt;Questions :&lt;/P&gt;
&lt;P&gt;1. Why is the above done ?&lt;/P&gt;
&lt;P&gt;2. When I am packetizing, I would not want to mark any macroblock as invalid for prediction, I would just use another RTP packet to put the remaining macro blocks.&lt;/P&gt;
&lt;P&gt;Is it assumed in the MPEG4 encoded process that one encoded VOP has to fit into the size set by VideoPacketLength.&lt;/P&gt;
&lt;P&gt;I would appreciate it, if any help is given on the above questions.&lt;/P&gt;
&lt;P&gt;Thanks,&lt;/P&gt;
&lt;P&gt;Ram&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
&lt;P&gt;&lt;/P&gt;
