Ensures filenames end with the appropriate extension (necessary for
communicating the output format to both FFmpeg and OIIO) and moves overwrite
check from file dialog to render since it's still possible to type the
intended filename. Also checks the intended output directory and creates it
if it doesn't already exist.
Minor code path improvement. Since EncodeFrame() will try to stop the debug
timer if the encode is finished, it doesn't make sense to always start it
unconditionally after calling EncodeFrame().
Implemented the ability to copy/paste blocks/clips in the timeline. This did
require some large scale changes and reworking of the copy/paste system
introduced a few commits ago, but should be largely functional now.
Since waveforms are generated during the cache process, if clips don't cache,
a waveform isn't generated for them. Therefore for now, this optimization will
be disabled but should be re-enabled later when waveforms are improved to handle
this situation.
Since the node graph can have transform cross nodes, input keyframes may occur
at a different times requiring transforming between sequence time and media
time. This commit implements such a mechanism in all UI classes that need it.
Updates drag mime data to include a variable determining which streams are
enabled and which ones aren't (a binary qint64 where the 0s are disabled
and the 1s are enabled) rather than relying solely on the stream->enabled
values which can't be modified as part of the drag process.
Since other parts of the UI use OpenGL (through Qt), the viewer's context can
sometimes become non-current until the next time it draws. Since the color
processor is created before the main drawing function, the context could
occasionally be non-current causing its creation to fail. Subsequently trying
to use that color processor would trigger a segfault. This commit addresses that
by always making the context current before creating the color processor shader.
We don't develop with MSVC, we only use it for Windows builds so constantly
having to synchronize the warnings between it and GCC seems like a waste of
time.
