Currently float are converted to 16b uint in input part
using src depth (32 bits) in hScale16To19 and hScale16to15,
make an invalid shift for the data

So shift the value when using float input
like 16 bpc uint.

Add fix a memory leak issue as James's comments.

This is a temporary workaround for transcoding scenarious using libaom-av1
encoder, which currently can't propagate extradata during initialization.

This fixes the creation of the hls manifest in hlsenc.c by writing the
entire manifest at the end for VOD playlists. Live & Event Playlists are unaffected.
This also fixes the behavior with HLS_TEMP_FILE to work correctly when
-hlsflags temp_file is specified, instead of always relying on use_rename, which caused these problems.

This reverts commit e45ed155.

The Matroska spec was updated to not remove Sequence Header OBUs from key
frames, so this is no longer needed.

This will get ISOBMFF and Matroska up to date with the revised AV1 Codec
Configuration Box spec.
For now keep propagating raw OBUs as extradata until all libavcodec modules
are adapted to handle AV1CodecConfigurationRecord formatted extradata.

Also only initialize it in ff_av1_packet_split() and not ff_av1_extract_obu(),
same as h2645_parse, so GetBitContext specific failures may not affect the
latter.
