@defgroup lavc_bsf Bitstream filters
@ingroup libavc
Bitstream filters transform encoded media data without decoding it. This
allows e.g. manipulating various header values. Bitstream filters operate on
@ref AVPacket "AVPackets".
The bitstream filtering API is centered around two structures:
AVBitStreamFilter and AVBSFContext. The former represents a bitstream filter
in abstract, the latter a specific filtering process. Obtain an
AVBitStreamFilter using av_bsf_get_by_name() or av_bsf_iterate(), then pass
it to av_bsf_alloc() to create an AVBSFContext. Fill in the user-settable
AVBSFContext fields, as described in its documentation, then call
av_bsf_init() to prepare the filter context for use.
Submit packets for filtering using av_bsf_send_packet(), obtain filtered
results with av_bsf_receive_packet(). When no more input packets will be
sent, submit a NULL AVPacket to signal the end of the stream to the filter.
av_bsf_receive_packet() will then return trailing packets, if any are
produced by the filter.
Finally, free the filter context with av_bsf_free().

This defines a framework for converting between a coded bitstream
and structures defining all individual syntax elements found in
such a stream.
Conversion in both directions is possible. Given a coded bitstream
(any meaningful fragment), it can be parsed and decomposed into
syntax elements stored in a set of codec-specific structures.
Similarly, given a set of those same codec-specific structures the
syntax elements can be serialised and combined to create a coded
bitstream.

The codec is not known to be init-threadsafe (i.e. it might be unsafe

the codec calls external APIs that are not known to be thread-safe).

This file contains a fast, not so accurate integer implementation of the
forward DCT (Discrete Cosine Transform).
A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
on each column. Direct algorithms are also available, but they are
much more complex and seem not to be any faster when reduced to code.
This implementation is based on Arai, Agui, and Nakajima's algorithm for
scaled DCT. Their original paper (Trans. IEICE E-71(11):1095) is in
Japanese, but the algorithm is described in the Pennebaker & Mitchell
JPEG textbook (see REFERENCES section in file README). The following code
is based directly on figure 4-8 in P&M.
While an 8-point DCT cannot be done in less than 11 multiplies, it is
possible to arrange the computation so that many of the multiplies are
simple scalings of the final outputs. These multiplies can then be
folded into the multiplications or divisions by the JPEG quantization
table entries. The AA&N method leaves only 5 multiplies and 29 adds
to be done in the DCT itself.
The primary disadvantage of this method is that with fixed-point math,
accuracy is lost due to imprecise representation of the scaled
quantization values. The smaller the quantization table entry, the less
precise the scaled value, so this implementation does worse with high-
quality-setting files than with low-quality ones.

This file contains a slow-but-accurate integer implementation of the

A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
on each column. Direct algorithms are also available, but they are
much more complex and seem not to be any faster when reduced to code.
This implementation is based on an algorithm described in
C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
The primary algorithm described there uses 11 multiplies and 29 adds.
We use their alternate method with 12 multiplies and 32 adds.
The advantage of this method is that no data path contains more than one
multiplication; this allows a very simple and accurate implementation in
scaled fixed-point arithmetic, with a minimal number of shifts.

This file contains the basic inverse-DCT transformation subroutine.

I've made lots of modifications to attempt to take advantage of the
sparse nature of the DCT matrices we're getting. Although the logic
is cumbersome, it's straightforward and the resulting code is much
faster.
A better way to do this would be to pass in the DCT block as a sparse
matrix, perhaps with the difference cases encoded.

minimum alignment rules ;)
If you notice errors in the align stuff, need more alignment for some ASM code
for some CPU or need to use a function with less aligned data then send a mail
to the ffmpeg-devel mailing list, ...
!warning These alignments might not match reality, (missing attribute((align))
stuff somewhere possible).
I (Michael) did not check them, these are just the alignments which I think
could be reached easily ...
!future video codecs might need functions with less strict alignment

The following API around MediaCodec and MediaFormat is based on the
NDK one provided by Google since Android 5.0.
Differences from the NDK API:
Buffers returned by ff_AMediaFormat_toString and ff_AMediaFormat_getString
are newly allocated buffer and must be freed by the user after use.
The MediaCrypto API is not implemented.
ff_AMediaCodec_infoTryAgainLater, ff_AMediaCodec_infoOutputBuffersChanged,
ff_AMediaCodec_infoOutputFormatChanged, ff_AMediaCodec_cleanOutputBuffers
ff_AMediaCodec_getName and ff_AMediaCodec_getBufferFlagEndOfStream are not
part of the original NDK API and are convenience functions to hide JNI
implementation.
The API around MediaCodecList is not part of the NDK (and is lacking as
we still need to retrieve the codec name to work around faulty decoders
and encoders).
For documentation, please refers to NdkMediaCodec.h NdkMediaFormat.h and
http://developer.android.com/reference/android/media/MediaCodec.html.

ProgressFrame is an API to easily share frames without an underlying
av_frame_ref(). Its main usecase is in frame-threading scenarios,
yet it could also be used for purely single-threaded decoders that
want to keep multiple references to the same frame.
The underlying principle behind the API is that all that is needed
to share a frame is a reference count and a contract between all parties.
The ProgressFrame provides the reference count and the frame is unreferenced
via ff_thread_release_buffer() when the reference count reaches zero.
In order to make this API also usable for frame-threaded decoders it also
provides a way of exchanging simple information about the state of
decoding the frame via ff_thread_progress_report() and
ff_thread_progress_await().
The typical contract for frame-threaded decoders is as follows:
Thread A initializes a ProgressFrame via ff_thread_progress_get_buffer()
(which already allocates the AVFrame's data buffers), calls
ff_thread_finish_setup() and starts decoding the frame. Later threads
receive a reference to this frame, which means they get a pointer
to the AVFrame and the internal reference count gets incremented.
Later threads whose frames use A's frame as reference as well as
the thread that will eventually output A's frame will wait for
progress on said frame reported by A. As soon as A has reported
that it has finished decoding its frame, it must no longer modify it
(neither its data nor its properties).
Because creating a reference with this API does not involve reads
from the actual AVFrame, the decoding thread may modify the properties
(i.e. non-data fields) until it has indicated to be done with this
frame. This is important for e.g. propagating decode_error_flags;
it also allows to add side-data late.

ThreadProgress is an API to easily notify other threads about progress
of any kind as long as it can be packaged into an int and is consistent
with the natural ordering of integers.
Each initialized ThreadProgress can be in one of two modes: No-op mode
or ordinary mode. In the former mode, ff_thread_report_progress() and
ff_thread_await_progress() are no-ops to simply support usecases like
non-frame-threading. Only in the latter case perform these functions
what their name already implies.
