Updated patch for ticket #3720.
Above is an acceptable commit message, slightly
better would be:
"

I applied your patch with git am and what I get as commit
message is:
Updated patch for ticket #3720. flv: Add XV (Xunlei Video) support

This is not ok.

The following probably doesn't work for some very large files:

+    offset = ((avio_r8(ic) + rot & 0xff)<<24) |
+             ((avio_r8(ic) + rot & 0xff)<<16) |
+             ((avio_r8(ic) + rot & 0xff)<<8) |
+             ((avio_r8(ic) + rot & 0xff)) + 0x200000;


I suggested:
offset = ((avio_r8(ic) + rot & 0xff) << 24 |
           (avio_r8(ic) + rot & 0xff) << 16) |
           (avio_r8(ic) + rot & 0xff) <<  8) |
           (avio_r8(ic) + rot & 0xff)) + 0x200000;

The suggested notation is wrong, are you want to suggest ?

offset =((avio_r8(ic) +rot &0xff) <<24|
(avio_r8(ic) +rot &0xff) <<16|
(avio_r8(ic) +rot &0xff) <<8|
(avio_r8(ic) +rot &0xff)) +0x200000;

There are still "for(" that should be "for (", "if(" that should be "if ("
and "+ rot )" that should be "+ rot)" (or no parentheses).
The script tools/patcheck should find them, it will also tell you
to add a line to Changelog and bump libavformat minor version.
