-Subject: [PATCH] mov: fix edit list issue that can cause A/V desync
-
-Only the first entry in the edit list was factored into the time_offset
-of the first sample in a track. But when there is a delay (empty edit
-entry) the mediatime from the second entry must also be factored into
-the time_offset.

-Subject: [PATCH] movenc: factor initial_padding into edit lists
-
-initial_padding was getting added to the edit list indirectly due to
-initial negative dts. But in cases where the audio is delayed,
-all or part of initial_padding would be unaccounted for. This patch
-makes initial_padding explicit.

-Subject: [PATCH] put_bits: bounds check buffer
-
-This prevents invalid writes outside put_bits' buffer.
-
-It also has the side effect of allowing measurement of the required
-size of a buffer without the need to pre-allocate an over-sized buffer.
-
-This fixes a crash in aacenc.c where it could write past the end of the
-allocated packet, which is allocated to be the max size allowed by the
-aac spec. aacenc.c uses the above feature to check the size
-of encoded data and try again when the size is too large.
