318efbfc10 h264: change unsupported bit depth message to error level
Unsupported bit depth is certainly an error the user will

07b77fe387 rtpdec: Read the packet length for all RTCP packet types
This allows skipping past unsupported RTCP packet types, as
RFC 3550 section 6.1 mandates.

Currently this only has any practical effect if a sender puts
an unrecognized type before RTCP_BYE in a compounded packet, or
(incorrectly) does not put RTCP_SR first.

c682514a8f qdm2: fix signed multiplication overflow
This code relies on the result wrapping as for unsigned
values, and the sign is not used.  Thus an unsigned type
is proper here.

5e87222fd1 flvdec: Don't export metadata entries that aren't proper metadata
This avoids writing these entries doubly if transcoding from
flv to flv, since the muxer blindly writes any and all metadata
keys set, in addition to the fixed fields that the muxer
always writes.

fdba370f8a h264: fix HRD parameters parsing
The bit_rate_value_minus1 and cpb_size_value_minus1 elements
allow a wider range than get_ue_golomb() supports.  This
adds a get_ue_golomb_long() function supporting up to 31
leading zeros, which is the maximum for these syntax
elements, and uses it in decode_hrd_parameters().

The level_code expression includes a shift which is invalid in
those cases where the value is not used.  Moving the calculation
to the branch where the result is used avoids these.

be1242a3f2 h264: fix detection of optional trailing PPS elements
The PPS may contain a few trailing elements whose presence is
only signalled by data remaining after the the mandatory part
has been parsed.  The current code fails to take into account
the rbsp_trailing_bits() when deciding whether to parse these
optional elements.  Assuming no unnecessary padding bytes are
passed to this function, the optional elements are present if
either more than 8 extra bits remain or the remaining bits do
not form a valid rbsp_trailing_bits() after the mandatory PPS
elements have been parsed.
