cbs_h264: Fix missing inferred colour description fields
...
With video_signal_type_present_flag set but colour_description_present_flag
unset the colour fields would not have had their correct values inferred.

avcodec/cbs_av1: keep separate reference frame state for reading and writing
...
In scearios where a Temporal Unit is written right after reading it using the same
CBS context (av1_metadata, av1_frame_merge, etc), the reference frame state used
by the writer must not be the state that's the result of the reader having already
parsed the current frame in question.
This fixes writing Switch frames, and frames using short ref signaling.

if (current->num_y_points)
num_pos_chroma = num_pos_luma + 1;

num_pos_chroma = num_pos_luma;
Max value for ar_coeff_lag is 3 (two bits), for num_pos_luma 24, and for

Both ar_coeffs_cb_plus_128 and ar_coeffs_cr_plus_128 may have up to

ff_id3v2_parse_priv_dict() uses av_dict_set() with the flags
AV_DICT_DONT_STRDUP_KEY and AV_DICT_DONT_STRDUP_VAL. In this case both
key and value are freed on error (and owned by the destination
dictionary on success), so that freeing them again on error is a
double-free and therefore forbidden. But it nevertheless happened.
Fixes CID 1452489 and 1452421.

avcodec/g729dec: require buf_size to be non 0
...
The 0 case was added with the support for multiple packets. It
appears unintended and causes extra complexity and out of array
accesses (though within padding)
No testcase

avcodec/g729dec: Use 64bit and clip in scalar product
...
The G729 reference decoder clips after each individual operation and keeps track if overflow
occurred (in the fixed point implementation), this here is
simpler and faster but not 1:1 the same what the reference does.
Non fuzzed samples which trigger any such overflow are welcome, so
the need and impact of different clipping solutions can be evaluated.
