      Refactor Tensor conversion in StreamReader (#3170) · 014d7140
      moto authored 
      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.

      Enhance UX on TorchAudio pages to improve awareness of doc versioning (#3167) · 92f2ea89
      Carl Parker authored 
      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.

      Refactor StreamReader - let StreamProcessor own codec context (#3157) · a8f4e97b
      Moto Hira authored 
      Summary:
Pull Request resolved: https://github.com/pytorch/audio/pull/3157

AVCodecContext plays central role in decoding and encoding.
Currently in StreamReader, the object is owned inside of Decoder class
and it's not accessible from other objects.

This commit move the ownership of AVCodecContext out of Decoder to
StreamProcessor class so that other components can check access its field.

Also, the Decoder class, which is super thin wrapper around AVCodecContext
object, is now absorbed to StreamProcessor class.

      moto authored 
      Summary:
This commit adds fields to OutputStream, which shows the result
of fitlers, such as width and height after filtering.

Before

```
OutputStream(

    filter_description='fps=3,scale=width=320:height=320,format=pix_fmts=gray')
```

After

```
OutputVideoStream(
    source_index=0,
    filter_description='fps=3,scale=width=320:height=320,format=pix_fmts=gray',
    media_type='video',
    format='gray',
    width=320,
