+API, and that means that you can also use QTextStream, QDataStream or

+QuaZIP provides complete abstraction of the ZIP/UNZIP API, for both

+Subject: [PATCH] bufferpool: Fix the buffer size reset code
+
+The offset in gst_buffer_resize() is additive. So to move back the
+offset to zero, we need to pass the opposite of the current offset. This
+was raised through the related unit test failingon 32bit as on 64bit
+the alignment padding was enough to hide the issue. The test was
+modified to also fail on 64bit. This patch will remove spurious
+assertions like:
+
+  assertion 'bufmax >= bufoffs + offset + size' failed
+
+Fixes #316
