016d40011a avcodec/extract_extradata: don't uninitialize the H2645Packet on every processed packet 
Based on hevc_parser code. This prevents repeated unnecessary allocations
and frees on every packet processed by the bsf.

0e782661d6 cbs_h264: Fix overflow in shifts 
The type of the result of a shift operation is unaffected by the type of
the right operand, so some existing code overflows with undefined behaviour
when the element length is 32.  Add a helper macro to calculate the maximum
value correctly and then use it everywhere this pattern appears.

3172b31223 avcodec/mediacodecdec: fix immediate EAGAIN with buffered packet 
In cases where the mediacodec decoder consumed a partial packet,
receive_frame() would start returning EAGAIN if the rest of the
packet couldn't be flushed and no frames were immediately available.

This fixes receive_frame() to perform its normal blocking wait for
new frames before returning EAGAIN. Fixes an issue I could reproduce
fairly often on a FireOS 6 device, and reported to be happening
intermittently by two mpv users.

688060fbb7 vc2enc: properly promote operations to 64 bits 
On Windows machines, the UL suffix still means 32 bits.
The only parts that need 64 bits are (1ULL << (m + 32)) and
(t*qf + qf). Hence, use the proper ULL suffix for the former
and just increase the type of the qf constant for the latter.
No overflows can happen as long as these are done in 64 bits and
the quantization table doesn't change.

936312d18c avcodec/mediacodecdec: add debug logging around hw buffer lifecycle 
Some Android devices are very finicky about how quicky output buffers
are returned back to the decoder, especially when they are associated
with a Surface.

This commit adds a new counter that keeps track of exactly how many hw
output buffers are being retained by the user, along with DEBUG level
logging that makes it easy to track the lifecycle of these buffers.
