| Summary | 0000180: 'Interleaved' parameter not working | ||||
| Description | Hello everyone, I'm currently trying to evaluate the quality of the intra-frame coding for H.264 and I think I found a little bug in the 'Interleaved' parameter. I modified the file encoder_baseline.cfg (copy-pasted in the 'Additional Information' field) to process my test.yuv file which is YUY2 (packed YUV). I added a line to the .CFG file with Interleaved = 1 (which according to JVT-AD010.doc provides for encoding packed format, the default being planar format). - If I use Interleaved = 1, I'm getting strange results after decoding - If I use Interleaved = 0, I'm getting good results at out but this is not the documented behaviour. In an unrelated matter, is it possible to set a 'quality' parameter like is available for JPEG? | ||||

It seems the file reader is working properly. Only the reconstructed file is still written in plain format. So if you set interleaved to 0 there is not format conversion and the reconstructed file appears to be in the same format. But since the encoder does not interpret the format properly, the coding performance is poor. I'm not sure if this is intended behavior. For quality settings see either the QP parameters or the rate control. |

Assigning this to Alexis who might want to add this functionality. |

Moved config to file attachment for easier access. Hope I fixed all additional line breaks. |
