Saxon e57e14678a container/mts: using RealTime type from utils package instead of global vars with mutator functions 2019-08-26 13:29:07 +09:30
Saxon b9cd6b3f13 container/mts/encoder.go: using NALTypeSPS from h264dec package 2019-08-26 09:24:18 +09:30
Saxon 817cc86a34 revid: now have MinPeriod and ClipDuration params 
This change included a rename of IntraRefreshPeriod to MinPeriod, and the addition of the ClipDuration param. PSI are now written before IDR. Clips are no longer outputed
based on PSI but rather a time ClipDuration, where ClipDuration >= MinPeriod, however, PSI must still be at the beginning of each clip. Also created functionality to update
meta time even if we don't have a response to update.

Saxon c55cd9a64e container/mts: wrote test for FindPSI and corrected bugs 
Wrote the FindPSI test which revealed a bug regarding creation of a PMT using comcast gots. This was fixed by writing Payload function and
extracting payload of PMT packet before giving to psi.NewPMT.
 2019-07-26 14:16:05 +09:30
Saxon 0825799cfa container/mts/mpegts.go: renamed IndexPid to FindPSIs and change such that only looked for PSI 
We have only ever used this function to find PSI so it makes sense to make it exclusive for this. It now also returns the streams found in the PMT. So that
we can actually retrieve the PIDs of the media and their types.

The contents within metaEncode_test.go were strongly related to the contents
in encoder.go, so the code was moved and the file was deleted.

Saxon 2bd7a009ce container/mts: BytesForMetaInterval renamed to TrimToMetaRange and now returns Clip for similar reasons to previous commit 2019-06-15 02:12:17 +09:30
Saxon ceee163b74 container/mts: BytesForPTSInterval renamed to TrimToPTSRange, and now returns a Clip 
It was concluded that it would be more useful if a function that provided a data segment from
the original clip just provided a new Clip, i.e. useful things like PTS and meta is still
available in the segment. So, BytesForPTSInterval was renamed to TrimToPTSRange and now
provides a Clip. The test for this function was updated accordingly.

Saxon 1323cbcae3 container/mts: filled Clip.Bytes 
writing Clip.Bytes required a change to the Clip type. The Clip type now possess a slice that
references the memory in which the Frames should reference for the media. Appropriate changes have
been made to Extract and TestExtract to accomidate this change.

Saxon 8f434e9703 container/mts: added payload_test.go and fixed bugs in Extract 2019-06-13 15:52:25 +09:30
Saxon b473451288 container/mts: added payload.go file with Extract function and types 
payload.go has been added which will contain functionality for dealing with MTS
payloads. A function has been added called Extract, which will return a Clip. Clip
is a type representing a sequence of media frames ([]Frame). Type Frame has been
added which represents a media frame. It provides fields to hold the media as
byte slice, PTS to hold the PES timestamp, an ID for identification of codec type
and finally the relevant Meta from the most recent PMT.
 2019-06-12 01:17:14 +09:30
Saxon e4bce3bcb3 container/mts: added ExtractMeta function and testing 
Added function to extract meta from first PMT found in a mpegts clip. This simply
wraps the logic we've used in vidrecord, i.e. Finding the PMT, converting to a
comcast gots psi.PSIBytesm, using HasDescriptor to get the meta descriptor, and
then mapping metadata. Also added testing.

Saxon 9af964cfc9 container/mts/meta: added GetAllAsMap function 
This function is very similar to GetAll, except that is returns a map[string]string rather
than a [][2]string. It's become apparent that a map[string]string might be more useful in
some circumstances.
