I have been using H263 codec and MPEG4 Simple Profilecodec and wanted to know what is the performance (CPU utilization) of each of the codec.
I am seeing that if I use MPEG4 decoder with short headerto decode a H263 stream the CPU utilization is higher than if I use H263 decoder by itself.
Thanks

Hi Jimish,
MPEG4 standard requires support for simple H.263 mode whereas H.263 spec itself have many extensions which are not part of MPEG4 spec. That is why we have two codecs.

Vladimir
