When users zero-init'd the struct, or left it as-is, the encode
queue family matched the graphics queue family, which led it to be
incorrectly logged as being used for encode.
This just improves the logging so this isn't printed anymore.
In f7ac3512f5b5cb8eb149f37300b43461d8e93af3 the size of the dynamically
allocated buffer was shrunk, but it was made too small for very small
alphabet sizes. This patch restores the size to prevent an OOB read.

Since 432adca5fedcb277b9a715a723cfd40735ec58f8 no decoder
looks at the slice_count and slice_offset fields at all,
so there is no reason to synchronize them between the worker
and the user thread.

Add a pointer parameter that if supplied will be used to return
the updated decode_error_flags. This will allow to fix several
races when using frame-threading; these resulted from AVFrame
that the earlier code updated concurrently being used as source
in an av_frame_ref() call in the decoder's update_thread_context.

When the marker writing code was merged from libav to FFmpeg
in dc62016c, it failed to take into account that the meaning of
cluster_pos had changed in bda5b662; in particular, the special
value for “I'm not currently working on a cluster” had changed
from 0 to -1. This makes the avio_write_marker() call never
be called. Update the if statement to fix it.

The fate-run.sh shell script exports LC_ALL=C before invoking the
test executables; this is probably done for consistency.
When executing Windows binaries with Wine, it normally handles
UTF-8 command line parameters just fine - but with LC_ALL set to
C, it treats them as plain ASCII.
As the unicode command line parameters wasn't the main thing
being tested here, just convert them to plain ASCII, for
portability. This fixes the test for all test configurations that
use Wine.

By default the OpenEXR decoder outputs linear light pixel data by
applying a gamma=1.0 transfer (i.e. a no-op). When it does so, it
should tag the data as linear so color-managed filters or other tools

The goal is to distinguish between APIs provided by the generic layer to
individual codecs and APIs internal to the generic layer.
Start by moving ff_{decode,encode}_receive_frame() and
ff_{decode,encode}_preinit() into this new header, as those functions
are called from generic code and should not be visible to individual
codecs.
This partially reverts commit d0fc1b3507c, which reintroduced a regression
originally fixed in 5e9986fd2d.

This example being first is now misleading because round-tripping
through hwdownload/hwupload is neither required nor recommended. Also,
the comment about avoiding format conversion is unnecessary because
`libplacebo` will now inherit the input frame format by default.
To support bitmap subtitle output, remove AV_CODEC_PROP_TEXT_SUB
property from codec descriptor for AV_CODEC_ID_ARIB_CAPTION.
This is similar to `libavcodec/libzvbi-teletextdec.c`
(AV_CODEC_ID_DVB_TELETEXT).
Instead, each subtitle decoder has to specify a subtitile format.
`libavcodec/libaribb24.c` uses same AV_CODEC_ID_ARIB_CAPTION and
expects AV_CODEC_PROP_TEXT_SUB to be set, so this adds a line to
specify a format there.

nodes (within a scope) in the graph, it just acts like other layers.
tf.nn.conv2d only creates one node in the graph, and no internal
nodes such as 'kernel' are created.

For example, given TensorFlow model file espcn.pb,
to generate native model file espcn.model, just run:
python convert.py espcn.pb
In current implementation, the native model file is generated for
specific dnn network with hard-code python scripts maintained out of ffmpeg.
For example, srcnn network used by vf_sr is generated with
https://github.com/HighVoltageRocknRoll/sr/blob/master/generate_header_and_model.py#L85
In this patch, the script is designed as a general solution which
converts general TensorFlow model .pb file into .model file. The script
now has some tricky to be compatible with current implemention, will
be refined step by step.
The script is also added into ffmpeg source tree. It is expected there
will be many more patches and community needs the ownership of it.
Another technical direction is to do the conversion in c/c++ code within
ffmpeg source tree. While .pb file is organized with protocol buffers,
it is not easy to do such work with tiny c/c++ code, see more discussion
at http://ffmpeg.org/pipermail/ffmpeg-devel/2019-May/244496.html. So,
choose the python script.
