Sebastian Dröge 88e060743a mxfdemux: Post an error message if we got EOS before having any source pads 
Otherwise, sending an EOS event has no effect and the application waits
forever for something to happen.

Nirbheek Chauhan 42af2d66d8 Add support for Meson as alternative/parallel build system 
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

Sebastian Dröge cc1feff99f mxfmux: Instead of releasing request pads on stop(), clear them only 
Request pads are requested by applications and as such should only be released
by them again. Instead of releasing them when stopping the muxer, just clear
their state so that they can be used again when starting the muxer again.

Sebastian Dröge 129b04fad0 mxftypes: Generate UUIDs according to RFC4122 version 4 (aka random) 
Instead of fully random UUIDs, these should follow a scheme.

Sebastian Dröge e222f28bf3 mxfmetadata: Best effort values must be written and if unset must contain the distinguished value 
It's invalid to not write them at all.

Sebastian Dröge 070d4312a8 mxful: Add missing OperationalPattern UL, which fixes an off-by-one with the others 2016-01-29 17:36:11 +01:00
Sebastian Dröge 2f40450d8e mxfmux: Our body partition is always complete and closed 
We have no metadata in it.
 2016-01-29 17:07:08 +01:00
Sebastian Dröge 5f3e444aff mxfmux: Use IndexSID of 2 instead of 1 
Some tools complain if essence and index have the same SID.

Sebastian Dröge 3df615a503 mxfmux: Write This Generation UID into the Identification metadata 
It's required according to the standard and we forgot to actually write it to
the file although we stored it in the data structures.

Sebastian Dröge b6696122a0 mxftypes: Don't store pointers in stack allocated guints 
This works usually in this place, unless the compiler optimizes things in
interesting ways in which case it causes stack corruption and crashes later.

The compiler in question here is clang with -O1, which seems to pack the stack
a bit more and causes writing to the guint as pointer to overwrite map.memory,
which then later crashes during unmapping of the memory.

Sebastian Dröge 7ae23d13c8 mxfdemux: Only pre-set position for exactly the same essence track 
The edit rate is only supposed to be the same in a source package, but there
might be multiple source packages with the same essence container. As such
just comparing the body/index SID is not sufficient.
 2015-12-10 12:47:17 +02:00
Sebastian Dröge 39aa2aaa39 mxfdemux: Only pre-set the track position if it's for the same body/index SID 2015-12-10 12:27:04 +02:00
Sebastian Dröge f2eaa68c90 mxfdemux: Only access the index table if it has enough elements 2015-12-09 16:55:00 +02:00
Sebastian Dröge 6e06f8c936 mxfdemux: Use keyframe information from index table segments if available 
We don't implement keyframe detection for all codecs and this will allow us to
implement better seeking.
 2015-12-09 16:49:30 +02:00
Sebastian Dröge b504672fc4 mxfdemux: Collect all index table segments after finding the random index pack 
That way we always have the index table information available, especially the
keyframe-ness of all buffers.
 2015-12-09 16:33:39 +02:00
Sebastian Dröge 6d367d6b48 mxfdemux: Fix handling of IndexTableSegments 
This was completely broken before and could only work on a very constrained
set of files. After these changes it should work except for situations where
PTS != DTS, which is not handled at all in mxfdemux currently.

Sebastian Dröge a02708f924 mxfmux: Add FIXME about enforcing that all tracks in a source package have the same edit rate 
The standard requires this and also the index table segments are not going to
work otherwise.
 2015-12-08 16:45:33 +02:00
Sebastian Dröge df7209a1c5 mxfmux: Write index table segments 
But only for the first essence track, and once for every keyframe every 2
seconds.

Sebastian Dröge 1addfcc0b2 mxfmetadata: Fix static local tag for index sid 2015-12-08 10:14:41 +02:00
Sebastian Dröge 47da7565ce mxftypes: Add function to serialize an index table segment to a buffer 2015-12-08 10:14:41 +02:00
Sebastian Dröge 01f0d16db3 mxfmux: Index table segments must not use the primer pack 
According to S377-1-2009c 9.2 the local tags must not be resolved from the
primer pack, which as a result means that there can't be any other tags than
statically assigned ones.

Sebastian Dröge 8541424d34 mxfmux: Error out if we get a timeout during live mixing 
We can't handle that but need complete streams without gaps.

Sebastian Dröge 73beb1834e mxfmpeg: Use the correct sound essence compression UL for MP3 
There's one for MPEG 1 Layer 1 and one for Layer 2 and 3. We previously
had the second for Layer 1 and 2 and nothing for Layer 3, which was wrong.
 2015-11-21 01:56:46 +05:30
Sebastian Dröge adb01a23da mxfmpeg: Set the essence container UL byte 13 to 0x10 for h264 
0x04 signifies a MPEG elementary stream but according to RP2008, 0x10 should
be used for a h264 byte-stream. This also fixes compatibility of our files
with ffmpeg.

Sebastian Dröge 04a5eee15e mxfmux: Remove some dead code that could never be called
