30d0674e7d avvideenc,avvidedec: Filtering hardware en/decoder by flag

80c8c05457 avviddec: Enforce allocate new AVFrame per input frame
... if ffmpeg would reuse the allocated AVBuffer. Reused AVFrame by
the ffmpeg seems to break our decoding flow since the reused AVFrame
holds the initial opaque data (GstVideoCodecFrame in this case), so
we couldn't trace the our in/out frames.
To enforce get_buffer() call per output frame, hold another reference
to the AVBuffer in order to mark the AVBuffer as not writable.

1e8e040fbc avviddec: improve latency calculation
When thread_type is set to FF_THREAD_FRAME, per the documentation
a latency of one frame per thread is introduced:

<https://ffmpeg.org/ffmpeg-codecs.html>, search for thread_type.

Additionally, we need in that case to calculate the automatic
number of threads ourselves, so as to accurately calculate the
latency.

e8f21b510a avviddec: Add thread-type property
The thread-type property allows specifying preferred
multithreading methods by user. Note that FF_THREAD_FRAME
may introduce additional latency especially on non-filesrc usecase,
since it introduces a decoding delay of (number of threads) frames.

603c78b1a1 gstav: Use libavcodec util function for version check
The version of libavutil is printed in the log instead of libavcodec
because avutil_version() returns LIBAVUTIL_VERSION_INT. This can be confusing,

935c21a9a9 avcfg: Override type of bitrate property from int64 to int
See https://gitlab.freedesktop.org/gstreamer/gst-libav/issues/41#note_142808

The switch to the new ffmpeg property system changed the type of the
bitrate property from int to int64, which potentially breaks many
existing applications at runtime as properties are usually set via
g_object_set().

As such, override the type to int until GStreamer 2.0.

ef8a1bdd90 avauddec: fix decoding of APE and Cook audio
.. and other formats where ffmpeg gives us multiple
subframes per input frame.

Since we now support non-interleaved audio, we can't
just concat buffers any more. Also, audio metas won't
be combined when buffers are merged, so when we push
out the combined buffer we'll look at the meta describing
only the first subframe and think it covers the whole
frame leading to stutter/gaps in the output.

We could fix this by copying the output data into a new
buffer when we merge buffers, but that's suboptimal, so
let's add some API to GstAudioDecoder to push out subframes
and use that instead.

1d293764e5 avdemux: fix negative pts if start_time is bigger than the ts
The start time is supposed to be the ts of the first frame.
FFmpeg uses fractions to represent timestamps and the start time may use a
different base than the frame pts. So we may end up having the start
time bigger than the pts because of rounding when converting to gst ts.

See https://gitlab.freedesktop.org/gstreamer/gst-libav/issues/51
for details.

21a18e22e1 avcfg: Ensure that ternary operator always evaluates to int64
When building with MSVC, if the 3rd operator is a double, the entire
expression always promoted double, and is then cast to int64.

When TRUE, this evaluates to (gint64) (gdouble) (INT64_MAX)
which overflows to INT64_MIN on MSVC, but not on C99 compilers.

This causes us to fail the g_return_if_fail inside g_param_spec_int64
when built with MSVC.

962d2a78fe avmux: Place pva case after generic case
In the function gst_ffmpeg_formatid_get_codecids() in the if / else if
construct the special case !strcmp (format_name, "pva") should be
handled before the generic case (plugin->audio_codec !=
AV_CODEC_ID_NONE) || (plugin->video_codec != AV_CODEC_ID_NONE)
This patch fixes the ordering.

gst_ffmpeg_formatid_get_codecids()

4596249496 avauddec: add support for decoding in non-interleaved layout
This removes the internal interleave loop and always negotiates
the native output layout of the libav decoder. Users can use
audioconvert to interleave if necessary.

Special care has been taken to leave the encoder unaffected by
the changes in avcodecmap, since GstAudioEncoder doesn't support
the non-interleaved layout yet.
