Attached patch aggregates information about dropped packets and only prints a message when dropping starts, and a summary when dropping ends.https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/494ttmlparse: Collect buffers until detecting complete xml document2020-10-29T18:57:01ZBugzilla Migration Userttmlparse: Collect buffers until detecting complete xml document## Submitted by Seungha Yang

## Description
As discussed on the mailing list here: https://lists.freedesktop.org/archives/gstreamer-devel/2018-April/067657.html
It appears that the passphrase parameter for the SRT plugins are not functioning correctly.
Copied from my original post in the mailing list:
We've been playing with the new SRT plugins as part of gst-plugins-bad and
all seems well apart from a couple of features.
Using it like so on the client (sender):
... srtclientsink passphrase=eb55dec3c22f4e0879baadfe2fd50151
uri=srt://10.10.10.10:6000...
And on the server (listener):
... srtserversrc passphrase=eb55dec3c22f4e0879baadfe2fd50151
uri=srt://:6000...
The first one being the passphrase parameter. At first, I assumed it was
working fine and the stream was encrypted, but after accidentally setting
the wrong password on the srtserversrc, to my surprise, the stream sill
worked. After some investigation, it seems that it works with or without a
passphrase, even if the passphrase is set on the srtclientsink.
I've tried everything it feels like to try and get this to work, this
includes:
- Setting the key-length to 16 even though that's the default
- Trying the other key-lengths
- Wrapping the passphrase in "quotes"
- Using different passphrases with different lengths
- Using only integers for the passphrase instead
... all on both sides of the pipeline.
However, it always seems that the stream is being sent unencrypted. Even
with debug level set on both plugins, there are no complaints or logs to
suggest anything is wrong.
I've scoured the web for examples but none can be found where the
passphrase is being used. So I'm now thinking there is either a bug or we
are doing something incorrectly here.
If we are doing something wrong, then I would have thought that something
should at least error or give a warning, rather than allow the stream to go
through unencrypted...

## Description
When mpegtsmux is in PLAYING oder PAUSED state, I can add sink-pads, but when I activate it and put data in, I get the Error:
Stream on pad sink_xxx is not associated with any program.
With this patch, a new pad is added to the default, when it is not associated with any program. So it's possible to simply add streams during state PLAYING and PAUSED.

## Description
Noticed when generating images with imperfect PTS, that when they get into the mxf stream with perfect PTS derived from the frame rate.
Expected result: original PTS are stored in the MXF stream.
Illustration: following generates a stream of ~ 3 fps declared as 30 fps, in mp4 and mxf.
The mysrc element is a quick & dirty element that takes stuff from stdin and sends it with arbitrary caps (based off videotestsrc).

The stream is then checked:

I didn't check the file to see if the mux or demux is the issue.

Various MXF files that actually have frame reordering output DTS>PTS. We have to offset all DTS backwards by the maximum difference between the two for this to work properly, by looking at the index.
This additionally will need the segment to be adjusted so that negative DTS are possible, just like in qtdemux.Edward HerveyEdward Herveyhttps://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/80mxfdemux: Add D10 mapping (MPEG-2 variant)2021-08-06T06:13:20ZBugzilla Migration Usermxfdemux: Add D10 mapping (MPEG-2 variant)## Submitted by Baldur Gislason

## Description
h264parse drop frames when there was no previous picture headers ( GST_H264_PARSE_STATE_VALID_PICTURE_HEADERS).
But some H264 encoder generate SPS header without PPS header following ...
The code in plugins-bad/gst/videoparsers/gsth264parse.c when receiving SPS GST_H264_NAL_SUBSET_SPS reset h264parse->state to 0 (meaning that previous SPS and PPS headers are ignored), instead of just considering SPS state only
So the change would be something like :
h264parse->state &= GST_H264_PARSE_STATE_GOT_PPS;
instead of
h264parse->state = 0;
