SunVideo Plus does not provide hardware-based MPEG1 I-B-P compression and XIL does not provide a software-based compressor, Therefore, programs relying on these capabilities will fail. Also, SunVideo Plus MPEG1 encodes non-square-pixel video, so applications expecting MPEG1 in square-pixel format will fail.
Error messages for SunVideo Plus are slightly different from SunVideo, so a program relying on trapping a particular error may not work.
SunVideo Plus's XIL compatibility is the same as that of the XIL library. Applications that make calls directly to the SunVideo driver may not work correctly.
If SunVideo Plus does not provide hardware acceleration for a given XIL molecule, the operation may be performed partly in software. This is currently true for some compression/resolution combinations.
SunVideo Plus supports the JPEG, CellB, and MPEG-1 (I frame) codes under compatibility mode. It also supports the uncompressed formats. SunVideo Plus does NOT support H.261 or MPEG1 (IPB frame) in compatibility mode.
