KongQun Yang 3f7ecd4e29 Workaround extra AUD in the access unit
VLC seems to generate access units with extra AUDs. In #526, the below
sequence is seen:

  AUD | SPS | PPS | SPS | PPS | AUD | SEI | SEI | SEI | IDR_SLICE

Previously we exit early when seeing AUD, which results in delayed
processing of the access unit.

The behavior is changed to continue processing the following NAL units
to workaround the content issue.

Closes #526.

KongQun Yang 33792ca2da Workarounds TS contents with dts moving backwards
Negative duration is not allowed, so set the duration of that sample to
an arbitrary small value in case it is needed to decode future samples.

Issue #451.

Kongqun Yang c223bc9144 Keep slice data partition NALs in clear
CENCv3 recommends only encrypting video data in slice NALs. Slice
data partition NALs should not be encrypted.

In the code, differentiate is_vcl and is_video_slice. They are the
same for H265; for H264, vcl NALs include slice data partition NALs
but video_slice NALs do not.

Kongqun Yang 09891dcd9e Fix access unit detection problem for H264
In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.

Fixes #134.

Jacob Trimble 9bb6c5d8d2 Add more unit tests for EsParserH26x.
This add several unit tests for EsParserH26x to test the various
NAL unit orders and access unit contents.  Some tests are disabled
and will be fixed in another patch.
