Added the property 'id' to the MediaFormat class
which serves as an identifier for the track.
DASH Representations will have the "id's" from their
Media Presentation Description mapped to the id property
in the MediaFormat class that will represent the track.
We needed this for an use case where we wanted to read the 'id'
value from the DASH representation and present it to the user
in order for the user to select the right track.
1. Change package name (rm "datasource")
2. Require injection of OkHttpClient through all constructors, and
remove allowCrossProtocolRedirect/connectTimeout/readTimeout
constructor arguments. The client should be configured with these
prior to injection.
3. Fix code style to be consistent with the project.
4. Simplify call to get contentLength. I'm pretty sure okhttp returns
the correct value when gzip is enabled, so there's no need to check
this in the data source.
5. Misc cleanups.
This change keeps the proportion offset * 256 as a floating point value rather
than rounding it before linear interpolation, which will increase precision
slightly when seeking in streams with XING headers.
In practice, this won't make much of a difference because precise seeking in VBR
MP3s with XING headers seems not to be possible without reading the entire file,
due to the fact that the (uneven) distribution of bits is represented by a fixed
number of table of contents entries.
- The old approach was technically incorrect, because the checks
were "capacity < sampleSize" and hence neglected the fact that
the buffer position may be greater than 0 (e.g. if the caller
wants to prefix the sample with some additional data).
- Also proactively throw an exception if the buffer is too small,
rather than wait for the failure when we actually do the write.
- Line parameter
- Added support for value and line alignment attributes.
- Support negative numbers when line is an absolute number (not a
percentage).
- Position parameter
- Added support for value and position alignment attributes
- Added support for WebVTT comment blocks
- Percentage values now accept decimal numbers (as webvtt spec states)
- Added new WebVTT tests for testing all new implemented features
