What is
OGM?
Ogg Media (OGM), meaning
Ogg Media File, is a container format (for video, audio and subtitle streams).
It was developed by Tobias Waldvogel and can do a few things the common AVI
format cannot.
OGG Media is a video file format with OGG container. It is not as popular
as Matroska.
To convert OGG media files to other formats with River Past software,
please have either Torbias' OGG
DirectShow Filters or Radlight
Ogg Media Filters installed. You may also need CCCP.
What is
MPA?
There are three "layers" in the MPEG-1
Audio specification.
In MPEG Audio Layer-1, a simple 32-subband audio compressor using a floating
point representation for subband samples. Resolution and scale factor are stored
for groups of 12 subsamples. MP1 is only used for Philips DCC Digital Compact
cassette with data rates of 384 kbps.
Both MPEG-1 and MPEG-2 files use MPEG-1
Audio Layer-2.
MPEG-1 Audio Layer-3 becomes
the widely popular MP3.
MPEG.ORG is an excellent source for additional
information on MPEG format and usage.
To encode MPEG Audio, you will need River
Past MPEG-2 Booster Pack in addition to your audio software.
