Lagarith is a lossless video codec intended for editing and archiving. Lagarith offers better compression than codecs like Huffyuv, Alparysoft, and CorePNG. There are a few lossless codecs that can compress better than Lagarith, such as MSU and FFV1; however Lagarith tends to be faster and stabler than these codecs.

Revision History:

Version 1.3.27
  • Release Date: Dec 9, 2011
  • Download(s):
  • Fixed a crash that could occur when the source video buffer is not aligned to a multiple of 8 for 32 bit systems. The issue still exists for 64-bit systems, but the fix for them isn't nearly as easy and it is a very rare issue so I am leaving it alone for now. Thanks to Peter Dimov for reporting this and providing a way to reproduce the issue.
  • Restored a table entry in the Fibonacci coder I accidently deleted; this would cause video corruption or crashes when playing back high-resolution video.
  • Fixed some pointers being treated as 32-bit integers when instantiating the codec; this could result in the pointer being trucated and the application crashing on 64 bit systems. Thanks to Stuart MacKinnon for reporting this and tracking down the cause.
  • Added exception handling in the range decoder; I am still getting a few reports of issues with Adobe products, and this will help me determine if there is still a buffer overrun in certain cases.
