The start time is supposed to be the ts of the first frame.
FFmpeg uses fractions to represent timestamps and the start time may use a
different base than the frame pts. So we may end up having the start
time bigger than the pts because of rounding when converting to gst ts.
See https://gitlab.freedesktop.org/gstreamer/gst-libav/issues/51
for details.
This commit adds a .gitlab-ci.yml file, which uses a feature
to fetch the config from a centralized repository. The intent is
to have all the gstreamer modules use the same configuration.
The configuration is currently hosted at the gst-ci repository
under the gitlab/ci_template.yml path.

When building with MSVC, if the 3rd operator is a double, the entire
expression always promoted double, and is then cast to int64.
When TRUE, this evaluates to (gint64) (gdouble) (INT64_MAX)
which overflows to INT64_MIN on MSVC, but not on C99 compilers.
This causes us to fail the g_return_if_fail inside g_param_spec_int64
when built with MSVC.
This matches all other plugins in the other gstreamer repos. This is
also necessary for generating the correct libtool archive (.la) files
in Cerbero which are needed for static linking on Android and iOS.
We don't want to export any symbols from the ffmpeg static libraries
we link to when building inside Cerbero. In the Autotools build, we
pass -export-symbols-regex to libtool which ensures this for us.
In the function gst_ffmpeg_formatid_get_codecids() in the if / else if
construct the special case !strcmp (format_name, "pva") should be
handled before the generic case (plugin->audio_codec !=
AV_CODEC_ID_NONE) || (plugin->video_codec != AV_CODEC_ID_NONE)
This patch fixes the ordering.
I stumbled accorss this issue while adding a new format to
gst_ffmpeg_formatid_get_codecids()

This removes the internal interleave loop and always negotiates
the native output layout of the libav decoder. Users can use
audioconvert to interleave if necessary.
Special care has been taken to leave the encoder unaffected by
the changes in avcodecmap, since GstAudioEncoder doesn't support
the non-interleaved layout yet.

We were ignoring these before the port to 4.0, interpreting them
as GST_FLOW_ERROR / GST_ELEMENT_ERROR causes check failures.
We should start using GST_*_DECODER_ERROR in latter commits,
for now simply restore the previous behaviour.
avcodec_align_dimensions2 uses context->pix_fmt to make its
calculations, we thus need to make sure it is adequately set
when calling it.
Fixes:
gst-launch-1.0 videotestsrc ! video/x-raw, width=1920, height=1080 \
! avenc_mpeg4 ! avdec_mpeg4 ! xvimagesink
This showed invalid writes under valgrind, then segfault.
