H.264 low latency - IVIDEO_NUMROWS
H.264 codec user guide describes the functionality of low latency.
This functionality allows user to encode/decode a sub-frame level data
communications. Without low latency, user can only encode/decode a
complete/full frame only.
More information about H264 low latency can be found in codec release
package:
* H.264 Encoder 2.0 on HDVICP2 and Media Controller Based Platform
User's Guide (SPRUHG3), Appendix G - Low Latency / Sub Frame Level
Synchronization
* H.264 Decoder 2.0 on HDVICP2 and Media Controller Based Platform
User's Guide (SPRUHF9), Appendix I - Low Latency / Sub Frame Level
Synchronization
This commit is only implemented low latency with IVIDEO_NUMROWS.
H.264 encoder handles inputDataMode = IVIDEO_NUMROWS with getDataFxn
as callback to get the numRows being filled into the inputBuffer pointer
passed at process call.
From H.264 encoder user guide Appendix G, more details can be found in
sec. G2 H.264 Encoder Input with sub frame level synchronization
H.264 decoder handles outputDataMode = IVIDEO_NUMROWS with putDataFxn as
callback to notify client on the numRows/numBlocks being filled by codec
into the outputBuffer pointer passed at process call.
From H.264 decoder user guide Appendix I, more details can be found in
sec. I.2 Details of using Sub Frame Level data sync at output side.
The changes depend on the changes done on LIBDCE DCE client:
