[FFmpeg-devel] [PATCH] avformat/dhav: Fix incorrect non-DHAV chunk skipping logic

DAV files may contain a variable length padding in between chunks filled with 0xff bytes. The current skipping logic is incorrect as it may skip over DHAV chunks not appearing sequentially in the file. We now look for the 'DHAV' tag using a byte-by-byte search in order to handle such situations. A

[FFmpeg-devel] Fix for avformat DHAV parsing issue.

Hello FFmpeg developers, Iv'e noticed some DAV files containing a 0xff's padding in between DHAV chunks. This is possible when the Dahua DVR device generates a DAV file which is concatenated from 2 different DAV files kept on the device hard drive. Here
