libopenshot

examples

Added some new audio sample scaling code, and fixed a huge bug with scoping the AVPacket in the correct spot, which was breaking many audio codecs... Also added a new mono audio test file.

AudioBufferSource.cpp

FIxed some big audio bugs, and finally got the audio reversing correctly working. Now, audio waves are reversed when a time map is moving backwards. There are still some pops and crackles, but I'll fix those later.

AudioResampler.cpp

FIxed some big audio bugs, and finally got the audio reversing correctly working. Now, audio waves are reversed when a time map is moving backwards. There are still some pops and crackles, but I'll fix those later.

Cache.cpp

Made decklinkOutput keep scheduling the last successfull frame, if the queue runs out. Also, made the timeline multi-threaded, and improved the DecklinkInput.cpp to keep frames in order, by returning the correct frame based on the number.

2013-02-12 01:28:48 -06:00

Clip.cpp

Fixed a bug where Clips were not determining their duration correctly.

2012-12-07 01:05:48 -06:00

CMakeLists.txt

Adding the initial version of the decklink writer, and a fully working (full circle) blackmagic example executabe, which processes real-time HD video and output's it via HDMI.

2013-02-10 02:19:40 -06:00

Coordinate.cpp

Added delta() to a coordinate, to track the change in unique value on the Y axis. This helps in time mapping, to track how many frames have been skipped.

2012-10-19 22:24:54 -05:00

DecklinkInput.cpp

Changes made to the live greenscreen display at SCALE 11X.

2013-06-06 23:15:01 -05:00

DecklinkOutput.cpp

Fixed many, many blackmagic bugs, and have a pretty good demo built.

2013-02-15 00:23:55 -06:00

DecklinkReader.cpp

Optimized the compositing of simple layers (with no transformation), by not resizing it's canvas to match the timeline. Also, improved the Decklink reader to wait for the frame to become available (if it's in the future), and to jump ahead on the timeline if it gets behind. Blackmagic program can now composite 4 layers in real time.

2013-02-12 02:42:18 -06:00

DecklinkWriter.cpp

Improved the timeline compositing performance, fixed some blackmagic bugs, and finally have an actual chromakey demo working!

2013-02-10 21:16:46 -06:00

DummyReader.cpp

Made a few fixes to the frame mapper

2012-10-30 18:53:26 -05:00

FFmpegReader.cpp

Fixed many, many blackmagic bugs, and have a pretty good demo built.

2013-02-15 00:23:55 -06:00

FFmpegWriter.cpp

libavcodec version 54 requires a different formula for nb_samples, used in audio encoding. So, I've added in conditional code, so audio works on the newest version of FFmpeg.

2012-12-03 13:03:04 -06:00

FileReaderBase.cpp

Replaced last_video_frame and last_audio_frame with a single last_frame variable, and refactored some related code. This fixes a big audio seeking bug.

2012-07-06 15:17:57 -05:00

FileWriterBase.cpp

Made Keyframe objects thread safe, by generating the values as Points are added, and the Timeline's Open and Close logic was made thread safe, so a reader is not closed while it's still being accessed on another thread. Also removed some unneeded code and comments.

2012-12-03 22:55:46 -06:00

Fraction.cpp

Fixed tons of issues related to video timebase being different than the video framerate. Also, added new properties for interlaced video, correctly detect pixel ratio, and fixed Display() to adjust for pixel ratio. Also added sample_rate to a frame, so it can playback audio at the correct rate. Refactored FFmpegReader to make most methods private, and only expose the important methods publicly.

2011-12-11 20:42:50 -06:00

Frame.cpp

Changes made to the live greenscreen display at SCALE 11X.

2013-06-06 23:15:01 -05:00

FrameMapper.cpp

Refactored the audio waveform generation into the Timeline class. Added the ability to set the volume, and the ability to mix layers of audio samples together. Also, made the waveform's have a transparent background, so they can be layered on top of other layers.

2012-11-29 16:32:48 -06:00

FrameRate.cpp

Fixed a regression with audio files and seeking, added a few new methods, and more accurately detect the End() of clips.

2012-10-14 02:36:05 -05:00

ImageReader.cpp

Fixed a big audio bug, where varying timestamp values on low precision audio timebases (i.e. 1/1000) would leave small gaps in the audio wave. Also, fixed a few issues related to sample_rate getting lost between the reader and clip and timeline objects.

2012-11-20 16:22:50 -06:00

KeyFrame.cpp

Added alpha to all FFmpegReader source images, which is needed by the timeline class. Also, added alpha to the AddColor() method. Now even the background of the timeline can be transparent, along with all layers... even the bottom layer.

2012-12-04 02:21:01 -06:00

Main_Blackmagic.cpp

Changes made to the live greenscreen display at SCALE 11X.

2013-06-06 23:15:01 -05:00

Main.cpp

Refactored blackmagic capture example into DecklinkCapture.cpp, and added it into libopenshot. Also, added a new, Main_Blackmagic.cpp example program, which invokes the DecklinkCapture.cpp class.

2013-02-06 02:09:21 -06:00

openshot.i

Adding the initial version of the decklink writer, and a fully working (full circle) blackmagic example executabe, which processes real-time HD video and output's it via HDMI.

2013-02-10 02:19:40 -06:00

Player.cpp

Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

2012-10-14 03:43:52 -05:00

Point.cpp

Renamed some of the basic clip property getters and setters, and added some simpler ways to get the value of and add points to a key frame.

2012-10-04 15:07:29 -05:00

TextReader.cpp

Fixed conditional compile flag for black magic, and improved the quality of the TextReader font rendering.

2013-02-08 02:15:16 -06:00

Timeline.cpp

Fixed many, many blackmagic bugs, and have a pretty good demo built.
