52ac7cf27a videoparser: comment unused GST_BASE_PARSE_FRAME_FLAG_PARSING
GST_BASE_PARSE_FRAME_FLAG_PARSING value is wrong, and the same flag is
not being used presently. Hence changing the value and commenting it out.
This needs to be included in baseparse.h later on

4d17166b03 mpegvideoparse: Differentiate the mpeg-2 stream from mpeg-1 based on pic_ext
Presence of picture extension header identifies the stream as mpeg2.
We are supposed to set the mpegversion to 2 if there is a picextension
instead of blindly setting the version to 1

830a4aa7f4 mpegvideoparse: look beyond start code before leaping
In case more data than a start code alone is needed to decide whether
it ends a frame, arrange for more input data and decide when available.

7c23a6f23c mpegvparse: Fix last start code position when input buffer is empty
When the input buffer is empty and we need more data to determine
whether or not to terminate the previous frame, the last start code
location needs to be set to 4 bytes before the the current position
(size of start_code is 32-bits)

654744a03c mpegvideoparse: Use sequence_display_extension values to update the src caps
The caps should always represent what the user is supposed to see.
So if there is a sequence_display_extension associated with the
stream then use the display_horizontal_size/display_vertical_size
to update the src caps (if they are less than the values provided
by sequence header).

d10acd3879 mpegvideoparse: cope with new parser API.
Migrate the code to use the new parser API based on GstMpegVideoPacket.

Also try to optimize gst_mpegv_parse_process_config() by using more of
GstMpegVideoPacket and determining the extension_start_code_identifier
prior to calling the parser function for that extension packet.

f1a6d84a6c mpegvideoparse: don't announce incomplete source caps
Don't send any source caps yet if we're still in
drop-buffers-until-we-get-a-sequence-header mode.

Fixes transmuxing of many MPEG-TS/PS streams into
formats which require things like width, height or
codec_data on the input caps.

Also fixes issues when using playbin with decoder
sinks that want width/height etc.

168c8406b5 Unrevert: mpegvideoparse: set timestamp based on pic offset
API is now in baseparse in gstreamer.

Timestamps in MPEG-TS streams are based on the last timestamp
before the start code of the picture.  GstBaseParse sets the
timestamp based on the beginning of the sequence header, if
one exists before the picture.  This fixes the case where the
timestamp occurs in the MPEG-TS stream between the seq header
and picture start code.

9f1257330d videoparsers: Use the peer caps for restrictions instead of the srcpad allowed caps
Otherwise we will intersect with the srcpad template caps and add all the caps fields
that the parser will ever set, no matter if downstream restricts this field or not.
This requires upstream to set this field on the caps to successfully negotiate.

b7d63d3fb1 videoparsers: Disable PTS interpolation in the base parse class
All these formats have re-ordered PTS which the base class gets
wrong. It's better to leave them blank and let the decoder sort it
out. Better yet would be to track and interpolate the timestamps
in the subclasses (FIXME)

c5c44628fc mpegvideoparse: Handle Sequence Display Extension
Change the way the pixel-aspect-ratio is computed by
interpreting the sequence header aspect ratio info
as MPEG-1 values until a sequence extension or
sequence display extension is seen, and then updating
the sequence header struct accordingly.

Fixes incorrect anamorphic display on some MPEG-2 (DVD)
sequences.

a9f46ed059 mpegvideoparse: only apply repeat count when set
When there is no extension header, the repeat_count variable is left to 0 and
then the duration on the output buffers is calculated wrongly. Because the
duration is used to interpolate output timestamps, the output timestamps are
also wrong, causing bad framerates.

7c6093357b videoparsers: Fix GstBaseParse::get_sink_caps() implementations
They should take the filter caps into account and always return
the template caps appended to the actual caps. Otherwise the

know about width, height, etc.

This reverts commit 91210831ee672343a296f31357144359d5c2e768.

Such explicit reset should not be needed as it is arranged for by
the baseclass in unison with monitoring for a new frame by subclass.

As such it might wrongfully hide something else going on ...
