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.

In these cases, only drop dts. Because if we drop both we have no
timestamps at all for some files.

The decoder is float-based and the test needs to allow for some fuzz.

It is hardcoded to 15fps.

Every supported format is converted to RGB.

This allows running all the tests individually and/or in parallel.

Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

It has not been properly maintained for years and there is little hope
of that changing in the future.
It appears simpler to write a new replacement from scratch than
unbreaking it.

Over-counting occurs if framerate is not set.

Fixes calculating the ts offset for audio codecs with delay.

Do not fall back on the codec timebase, since that can be anything for
VFR video.

This results in DefaultDuration not being written when the framerate is
not known, but as this field is purely informative, this should not
break any sane demuxers.

This corrects the bug that caused the checksums to change in
9767d7c0.

It caused the EOS flag to be set incorrectly; the ogg spec does not
allow it to be set in the middle of a logical bitstream.

Before, header information for ogg format files was sent with the
first encoded packet.

This patch makes it so that it is possible for API users to
differentiate between headers and encoded audio. This is useful, for
example, when creating an audio stream where you want to send one set
of headers for every client that connects and then the encoded stream
of audio.

Also, stop using AVCodecContext.codec_name as fallback, since it will be
deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.
