Pull Request resolved: https://github.com/pytorch/audio/pull/3223

Each `StreamProcessor` is responsible for processing a source stream. In the case where we support packet passthrough, `StreamProcessor`'s choice of decoder is irrelevant as no decoding is performed. Currently, however, `StreamProcessor` requires decoder params and fixes a decoder at construction time. To accommodate this future packet passthrough use case, this PR decouples the construction of `StreamProcessor` from the configuration of the decoder that it uses.

Summary:
This commit adds the equivalent of `qscale` option in FFmpeg to StreamWriter.CodecConfig.
`qscale` enables variable bit rate.

The following figure illustrates the difference between currently available configs.
From top to bottom; original, `compression_level=1`, `compression_level=9`, `bit_rate=192k`, `bit_rate=8k`, `qscale=9`, `qscale=1`.

Summary:
This commit adds support for changing the spec of media
(such as sample rate, #channels, image size and frame rate)
on-the-fly at encoding time.

The motivation behind this addition is that certain media
formats support only limited number of spec, and it is
cumbersome to require client code to change the spec
every time.

For example, OPUS supports only 48kHz sampling rate, and
vorbis only supports stereo.

To make it easy to work with media of different formats,
this commit makes it so that anything that's not compatible
with the format is automatically converted, and allows
users to specify the override.

Notable implementation detail is that, for sample format and
pixel format, the default value of encoder has higher precedent
to source value, while for other attributes like sample rate and
#channels, the source value has higher precedent as long as
they are supported.

This commit removes some tests for file-like object from StreamWriter test.

The rational is that testing things after the output file is opened are
same for file-like object and regular files. Things like filter-graph and
encoder format change does not affect how the encoded bynary are written.

Summary:
In https://github.com/pytorch/audio/issues/3178, a mechanism to cache HW device context was introduced.
This commit applies the reuse in StreamWriter, so that
when using GPU video decoding and encoding, they are shared.

This gives back about 250 - 300 MB of GPU memory.

 ---

Q: What is HW device context?
From https://ffmpeg.org/doxygen/4.1/structAVHWDeviceContext.html#details
> This struct aggregates all the (hardware/vendor-specific) "high-level" state, i.e.
>
> state that is not tied to a concrete processing configuration. E.g., in an API that supports hardware-accelerated encoding and decoding, this struct will (if possible) wrap the state that is common to both encoding and decoding and from which specific instances of encoders or decoders can be derived.

Summary:
Pull Request resolved: https://github.com/pytorch/audio/pull/3205

This commit refactors the initialization of EncodeProcess.

Interface-wise, the signature of the constructor of EncodeProcess
has made simpler just to take rvalues of its components, and the
initialization of the components have been moved to helper functions.

Implementat-wise, the order that the components are initialized is
revised, and the source of initialization parameters is also revised.

For example, the original implementation first creates AVCodecContext,
and passes it around to create the other components. This relied on
an assumption that parameters AVCodecContext has (such as image size
and sample rate) are same as the source data. This is not always right,
and as we will introduce custom filter graph and allow on-the-fly
transform of rates and dimensions, it will become even less correct.

The new initialization constructs source AVFrame, TensorConverter and
FilterGraph from source attributes. This makes it easy to introduce
on-the-fly transform.

Summary:
Some audio encoders expect specific, exact number of samples described as in `AVCodecContext.frame_size`.

The `AVFrame.nb_samples` is set for the frames passed to `AVFilterGraph`,
but frames coming out of the graph do not necessarily have the same numbr of frames.

This causes issues with encoding OPUS (among others).

This commit fixes it by inserting `asetnsamples` to filter graph if a fixed number of samples is requested.

Note:
It turned out that FFmpeg 4.1 has issue with OPUS encoding. It does not properly discard some sample.
We should probably move the minimum required FFmpeg to 4.2, but I am not sure if we can enforce it via ABI.
Work around will be to issue an warning if encoding OPUS with 4.1. (follow-up)

Summary:
StreamReader behaves differently when dealing with YUV formats.
It implicitly converts the image format to YUV444P because
otherwise image planes do not have the same shape and it is not
possible to express it as a regular PyTorch Tensor with dedicated

This is commit adds warnings to such conversions.

Summary:
OPUS encoder and VORBIS encoders require "strict=experimental" flags. This commit enables it automatically.

The rational behind of it is typically we care if we can encode these formats at all and not how they are encoded. (This might be concern when these encoder becomes more mature on FFmpeg side and providing flags would result in weird behavior)

Also when writing high-level functions that uses StreamWriter, if we do not set these flags, then these high-level functions have to add new options that should be passed down to StreamWriter, which turned out to be very painful in https://github.com/pytorch/audio/issues/3163

Summary:

Refactor the process after decoding in StreamRader.

The post-decode process consists of three parts,
1. preprocessing using FilterGraph
2. conversion to Tensor
3. store in Buffer

The FilterGraph class is a thin wrapper around AVFilterGraph
structure from FFmpeg and it is agnostic to media type. However
Tensor conversion and buffering consists of bunch of different
logics.

Currently, conversion process is abstracted away with
template, i.e. `template<typename Conversion> Buffer`, and the whole
process is implemeted in Sink class which consists of `FilterGraph`
and `Buffer` which internally contains Conversion logic, even
though conversion logic and buffer have nothing in common and beter
logically separated.

The new implementation replaces `Sink` class with `IPostDecodeProcess`
interface, which contains the three components.
The different post process is implemented as a template argument of the
actual implementation, i.e.

```c++
template<typename Converter, typename Buffer>
ProcessImpl : IPostDecodeProcess
```

and stored as `unique_ptr<IPostDecodeProcess>` on `StreamProcessor`.
([functionoid pattern](https://isocpp.org/wiki/faq/pointers-to-members#functionoids), which allows to eliminate all the branching based on the media format.)

Note:
This implementation was not possible at the initial version of
StreamReader, as there was no way of knowing the media attributes coming out
of `AVFilterGraph`. https://github.com/pytorch/audio/pull/3155 and https://github.com/pytorch/audio/pull/3183
added features to parse it properly, so we can finally make the post processing strongly-typed.

Tweak internals of StreamReader
1. Pass time_base to Buffer class so that
    * no need to pass frame_duration separately
    * Conversion of PTS to double type can be delayed until when it's popped
2. Merge `get_output_timebase` method into `get_output_stream_info`.
3. If filter description is not provided, fill in null filter at top-level StreamReader
4. Expose filer and filter description from Sink class to get rid of wrapper get methods.

Fix the GPU memory leak introduced in https://github.com/pytorch/audio/pull/3183

The HW frames context is owned by AVCodecContext.
The removed `av_buffer_ref` call increased the ferenrence counting unnecessarily,
and prevented AVCodecContext from feeing the resource.

Summary:
This commit adds CUDA frame support to FilterGraph

It initializes and attaches CUDA frames context to FilterGraph,
so that CUDA frames can be processed in FilterGraph.

As a result, it enables
1. CUDA filter support such as `scale_cuda`
2. Properly retrieve the pixel format coming out of FilterGraph when
   CUDA HW acceleration is enabled. (currently it is reported as "cuda")

Summary:
Currently, when the Buffer converts AVFrame* to torch::Tensor,
it checks the format at each time a frame is passed, and
perform the conversion.

This commit changes it so that the conversion operation is
pre-instantiated at the time outside stream is configured.

It introduces Converter implementations for various formats,
and use template to embed them in Buffer class.
This way, branching like if/switch are eliminated from
decoding path.

Summary:
- Boldface the version-selection UX and increase size by three percent.
- Add text to breadcrumbs to indicate version and stability.
- New `breadcrumbs.html` in `_templates` overrides Sphinx version.

I create a new variable in `conf.py`, **version_stable**, which has the version number for the most-recent stable release. I define this variable in the **html_context** dictionary so that it is visible to the templates.

I use this approach because I was not able to find any other way of discerning the current stable release during the build. Note that the `versions.html` file--which identifies the current stable release--appears to be available only in the **gh-pages** branch and so it is not available at build time.

However, this means that someone will need to update `conf.py` whenever the current stable release changes.
