| Summary | 0000126: disable_deblocking_filter_idc - LoopFilterParametersFlag - DFParametersFlag | ||||
| Description | The example encoder configuration files and the software manual indicate that the LoopFilterParametersFlag needs to be used to disable (or adjust) the deblocking filter functionality. The encoder does not parse the "LoopFilterParametersFlag", instead it looks for the "DFParametersFlag". All other deblocking filter related input parameters have similar issues. | ||||

I believe that the input verification of the parameters DFDisableRefXSlice and DFDisableNRefXSlice with X being one of the slice types is incorrect. It only accepts values in the range [0;1] while it should accept values in the range [0;2]. Changing the maximum values in configfile.h seems to take care of the issue. In loopfilter.c the following code, indicating that 2 is a valid value, appears: if (MbQ->DFDisableIdc==2) { ... } Without the change to configfile.h, this 'if' statement will never result in 'true'. |

I have updated the draft version of the user manual for the changed loop filter options. Note, that there are still many more parameter updates to be documented. I also fixed the range of the parameters in my development tree. |
