The research shows that ordinal pattern distribution of unified IPMs can improve their tolerance to changes in encoder settings.
#Mediacoder x64 video settings update#
Experiments with different IPM-based descriptors, on a subset of the TRECVID/CCD 2011 collection with content-preserving visual distortions, compare the performance of four H.264/AVC encoding profiles ( High10, High, Baseline and Main) and also investigate the impact of three encoders ( FFmpeg, MediaCoder and JM). update MediaCoder build 3288 add raw video frames are retrieved from video source (MPlayer, AVISynth etc.) and sent to video encoders instead of letting video encoders to do decoding (in other words, MediaCoder is no longer a just launcher for various video encoders but can help them to decode what they cant, just like what MediaCoder. Similarly, applying different encoding-profiles can also have a negative impact. In content-based video retrieval using different encoders between a video and its copy can affect performance. However, in spite of their efficiency and effectiveness, they can be sensitive to encoder settings such as encoder-type and encoding-profile. Intra-prediction modes (IPMs) of H.264/AVC, as visual feature components, are easily extracted from the compressed domain.
