Use the following command to reproduce this issue:
make fate-vp8-size-change HWACCEL="vaapi -vaapi_device \
/dev/dri/renderD128 -hwaccel_output_format yuv420p"
SAMPLES=../fate-suite/.
At the same time, reconstruct the public logic as a function.

Before this patch persistent http connections would work only for media segments.
The playlists were still opening a new connection everytime.
This patch extends persistent http connections to playlists as well.

Since close is not called, during http persistent connection,
flush needs to be called so that output is written on time.

With FCPX 10.4, Apple has expanded the set of colorspace, primaries,
and trc flags officially supported in QuickTime files. The expanded set
matches the codepoints used in ffmpeg and many other specs.

If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.
Added option allows users to select between replacement and composition.
Tested and documented.

avcodec: add metadata to identify wrappers and hardware decoders
This commit is a noop, see b945fed629
Merged-by: James Almer <jamrial@gmail.com>
Explicitly identify decoder/encoder wrappers with a common name. This
saves API users from guessing by the name suffix. For example, they
don't have to guess that "h264_qsv" is the h264 QSV implementation, and
instead they can just check the AVCodec .codec and .wrapper_name fields.
Explicitly mark AVCodec entries that are hardware decoders or most
likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing
API users listing hardware decoders in a more generic way. The proposed
AVCodecHWConfig does not provide this information fully, because it's
concerned with decoder configuration, not information about the fact
whether the hardware is used or not.
AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software
implementations in case the hardware is not capable.

Hypothetical Reference Decoding (HRD) model assumes that data flows
into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
Smaller BufferSizeInKB means smaller frame size variations,
but more difficult to maintain HRD.
