    • Move muxer initialization off application thread · 194a32c0 
      Problem: We are initialising muxer as soon as we start the transformation. Now the startTransformation() method can be called from main thread, but muxer creation is an I/O operation and should be not be done on main thread.

Solution: Added lazy initialisation of muxer object. The actual transformation happens on background thread so the muxer will be initialised lazily from background thread only.

Another way was to provide an initialize() method on MuxerWrapper which will explicitly initialise muxer object but with this approach the caller need to call the initialise method before calling anything else. With current implementation the renderers are calling MuxerWrapper methods on various callbacks (Not sequentially) and also we are sharing same muxer with multiple renderers so It might become confusing for the caller on when to call the initialise() method. Also there are few methods on MuxerWrapper which dont really need muxer object. So in short it might make MuxerWrapper APIs more confusing.

Validation: Verified the transformation from demo app.

    • HDR: Set decoder codec profile and level if available. · 09698192 
      This should be necessary to ensure decoders see fewer errors.

Setting this resulted in removing native_dequeueOutputBuffer errors on OMX.MTK decoders for in-app tone mapping prototyping.

    • Make adding ad live breaks more robust · f06e8ee7 
      This change makes adding ad events in live streams more robust by allowing ad
groups to grow in number of ads if more ad events are received than initially
announced by the SDK.

With the IMA prefetch feature, an AdPod can grow in size in certain conditions
like from initially 2 ads to 4 ads being part of the ad group. With this change,
if an additional ad event arrives while the ad group is still being played,
the ad group is expanded. If the event arrives late and the ad group is already
completed, a new group is created for the remaining ads.

This also covers the case where we join the live stream while an ad is being
played and we missed at least one LOADED event from the SDK. Ads of the group
before the first LOADED event are ignored in such a case.

    • Fix `Cea608Decoder` handling of service switch commands in field 2 · 6b3bec86 
      From ANSI-CTA-608-E R-2014 section 8.4:
> When closed captioning is used on line 21, field 2, it shall conform
> to all of the applicable specifications and recommended practices as
> defined for field 1 services with the following differences:
> 1. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x14, 0x20 to 0x14, 0x2F in field 1,
>    shall be replaced with 0x15, 0x20 to 0x15, 0x2F when used in field
>    2.
> 2. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x1C, 0x20 to 0x1C, 0x2F in field
>    1, shall be replaced with 0x1D, 0x20 to 0x1D, 0x2F when used in
>    field 2.

This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.

The `isMiscCode`  method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.
