MediaCoder now supports JM H.264 decoder and encoder (Stanley posted on July 14th, 2008 )

Since 0.6.1.4135, MediaCoder has integrated the support for JM H.264 decoder and encoder. JM H.264 decoder is able to decode the H.264 streams generated by many HD camcorders correctly which other open-source H.264 decoders cannot. JM H.264 encoder is one of the three major open-source H.264 encoder implementations. It has very rich parameters and support most features of H.264. Some frequently used parameters have been added into MediaCoder while the rest of thundreds of paramters can be adjusted by loading a JM configuration file (by specifying the configuration file path at “Configuration File” option). A JM configuration file is a plain text file.



The following is the configuration file with default values. You can use it as a template, alter values of parameters or remove the unchanged ones.

# New Input File Format is as follows
# <ParameterName> = <ParameterValue> # Comment
#
# See configfile.h for a list of supported ParameterNames
#
# For bug reporting and known issues see:
# https://ipbt.hhi.de
