There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: NRonald S. Bultje <rsbultje@gmail.com>

The length is even, so some unrolling can be performed. Timings are for x86: - 32bits: 102c -> 82c - 64bits: 82c -> 69c Signed-off-by: NRonald S. Bultje <rsbultje@gmail.com>

Fixes bug 240, as well as several integer overflows (visible as glitches) in other scaling output routines, e.g. YUV422.

It is used to parse fixed sized fields out of a single octet. The code is simpler without it.

Also, do not keep trying to find and open a decoder in try_decode_frame() if we already tried and failed once. Fixes always searching until max_analyze_duration in avformat_find_stream_info() when demuxing codecs without a decoder.

Use the estimated duration only to calculate missing timestamps if needed.

Also, do not give AVCodecContext.frame_size priority for muxing. Updated 2 FATE references: dxa-feeble - adds 1 audio frame that is still within 2 seconds as specified by -t 2 in the FATE test wmv8-drm-nodec - durations are not needed. previously they were estimated using the packet size and average bit rate.
