This is a bit ugly as it attempts to keep most of the computation
in integers before the double based fps code. The use of integers
is to reduce the chances of rounding differences between platforms
Previously the timestamp was rounded to the encoder timebase
before being converted back to double precision which could cause loss
of precision

The existing meridian audio test does not test
ff_mlp_rematrix_channel_arm. This sample (first 640k of
https://samples.libav.org/A-codecs/TrueHD/TrueHD.raw) uses
ff_mlp_rematrix_channel_arm. Since this sample has 5.1 channels it also
allows testing the integrated downmixing.
This uses the RIFF header stored size to figure out the expected AVI
file size, instead of the actual file. To work fully it requires handling
failed avio_seek() instead of assuming they always succeed.
Some fate file has been cut off and contains half a frame at the end which
previously was not output during demuxing. This frame is now output to
encoder, thus the fate diff update.

According to the DPX file format description found at
http://www.fileformat.info/format/dpx/egff.htm the ImageElement part of
the GenericImageHeader also contains an an offset to the real image data
beside the same member that can be found in the GenericFileHeader.
Libav keeps this member empty (=0) while some applications expects it to
be filled properly. FATE test updated accordingly.

Only shift limited range luma, and always only shift chroma
for upconversion.

The file is already present in git and by using it we can perform more tests
without the need of fate samples

This is a generic solution that will not reqiore modifications when new options are added.
This also fixes problem with current implementation when qmin or qmax=-1.
Only 8 bits was sent and read back as 255.

Function allows to create string containing object's serialized options.
Such string may be passed back to av_set_options_string() in order to restore options.

According to the DASH spec, Representation IDs should be unique
across all adaptation sets. Fixing that and updating the fate

It is derived from the actual equations of the specs. In
particular, it is closer to the inverse of what the encoder uses.

Uses a similar approach as vf_yadif to flush the last frame in idet.
Quick test with 50 frames from vsynth1:
./ffmpeg.old -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 | grep Multi
(gives) [Parsed_idet_0 @ 0x261ebb0] Multi frame detection: TFF:0 BFF:0 Progressive:48 Undetermined:1
./ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 | grep Multi
(gives) [Parsed_idet_0 @ 0x35a0bb0] Multi frame detection: TFF:0 BFF:0 Progressive:49 Undetermined:1
Fate tests have been updated.
(In testing, it seems this filter will also need a subsequent patch for single frame input)
