ChunkSampleSource had a null check solely for the VTT case,
where DashChunkSource wasn't setting a MediaFormat on VTT
chunks. It's trivial to do so, and is more consistent, so I've
done that and removed the null check. Also done some small
tidying.
This OMX component is listed but can't be instantiated on this device.
According to the GitHub issue, some other devices are also affected, so these
will have to be added too.
Issue: #377
They're current location is annoying, because it creates a dependency
from the dash package to the webvtt package. For apps like Play Movies
where WEBVTT isn't used, it's nice just to delete the whole package at
import time, which requires that this dependency be removed.
- There's definitely potential for more code sharing in these
classes, but deferring for now.
- Also made no-scheme default to file://, and allowed smoothstreaming
URLs to be specified with or without the /Manifest suffix.
Before preparation, and when seeking, Mp3Extractor did not handle retrying:
- synchronizedHeader was set before the header was known to be valid, which
means that after seeing one valid frame header and then failing to read, the
synchronization would be treated as complete.
- The input buffer would keep data loaded during synchronization but on the next
call to synchronize when retrying it was not returned to the mark position to
re-parse the data.
This change fixes these issues.
- Make HlsPlaylistParser treat non-positive dimensions as unknown.
- Make HlsPlaylistParser parse floating point resolutions, because
technically that's how they're spec'd.
- Make VideoFormatSelectorUtil treat non-position dimensions as unknown.
