I'm fighting with Chinese IP camera modules, one of them has chipset IMX322 and has 2MPX. I managed to connect to this camera (there was no doc.

Golomb coding is a lossless data compression method using a family of data compression codes invented by Solomon W. Golomb in the 1960s. Alphabets following a geometric distribution will have a Golomb code as an optimal prefix code, making Golomb coding highly suitable for situations in which the occurrence of small values in the input stream is significantly more likely than large values.

Fixes may be applied ifone can identify the specific patch(es) that resolve theissues from the upstream (and such patches can bebackported). Reviewing FFMpeg fixes might give youa clue as to which patches to test in your environmentto verify which (if any) help.mythtv-users mailing listmythtv-users@mythtv.orgMythTV Forums.
