The audio lexers need to know how much data they will be receiving unlike video which has a fixed buffer size.
This means that all the lex function will need to be given a buffer size since they are used as a function pointer with the same signature.
Started working on adding exposure, brightness, saturation and awb flags to revid-cli so that we can control raspivid parameters.
Updated revid logic to give these to raspivid and updated config to consider these parameters in config validation.
Removed packetization flag for revid-cli as no longer required.
Packetization will be decided based on outputs.
Removed buffer type definition and Write receiver func in
mtsSender_test.go as this is now defined in revid.go.
Made ringbuffer size and element size consisten no matter the
output methods, as we're now going to only be putting h264 in there.
Modified H264 lex function to take an io.Writer rather than an
Encoder.
Removed destination []loadSender slice from revids fields and
added an encoder []stream.Encoder slice to hold encoders used
during a particular configuration. Each encoder will write to
the desired outputs.
Modified logic regarding encoder and sender setup. We now check
what outputs we have and add encoders to revid's encoder slice
depending on what each output requires.
Modified outputClips routine such that it ranges through revid's
encoders and encodes to them. They then write to the senders and
they handle logic regarding the amount of data they send out
and when. They also handle actions to perform on send failures.
Wrote multiSender struct which will be written to from encoders.
It will then use it's senders to distribute the data accordingly
to senders that work with the encoding from said encoders.
Modified senders so that their load methods no longer take ring
chunks, but rather slices.
Modified senders such that their release methods no longer
perform chunk closing.
revid-cli: initialising config.Output slice when no outputs are defined so that a default output can still be set
