• 2266a4ab7a Improved Clip class, and worked on constructors, file readers (image and ffmpeg), and more curves (shear, perspective, and crop) Jonathan Thomas 2012-10-04 01:34:45 -05:00
• e96bd5ba98 Added the initial timeline and clip classes, with some of the initial curves and constructors. Jonathan Thomas 2012-10-03 01:55:24 -05:00

• 0f3758bc29 Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single". Jonathan Thomas 2012-08-28 15:53:18 -05:00
• c564a15ced Improved the multi-threaded code, by requiring a minimum of 8 frames to be processed by the reader. Jonathan Thomas 2012-08-26 02:44:05 -05:00
• 27d2cf629d Added a minimum # of packets to read in the FFmpegReader, which really helps utilize the multiple threads... and improved performance by 27% overall. Jonathan Thomas 2012-08-24 17:03:23 -05:00
• ed697a9c15 Added pool of software image scalers to the FFmpegWriter / encoder, and removed OMP critical section. Also, refactored some audio and video codecs, and changed "resize" to "scale" for speed improvements. Jonathan Thomas 2012-08-24 15:57:49 -05:00

• 2b5d317123 Fixed a multi-threaded encoding bug with audio-only files. Jonathan Thomas 2012-08-20 22:23:31 -05:00
• b98b8f8968 Fixed many bugs on the multi-threaded encoder, simplified the API, and removed some memory leaks. Jonathan Thomas 2012-08-20 14:26:49 -05:00
• 97b2717744 Fixed many bugs on the multi-threaded FFmpegWriter. Added audio multi-threading, and it mostly works... with a few bugs remaining. Jonathan Thomas 2012-08-20 02:59:35 -05:00
• 3f2855735e Added experimental multi-threaded features to the FFmpegWriter Jonathan Thomas 2012-08-20 00:02:09 -05:00
• ef2435eaea Updated project plan Jonathan Thomas 2012-08-16 01:27:25 -05:00
• 7cb17bdb5f Some profiling changes to test encoder performance Jonathan Thomas 2012-08-16 00:53:46 -05:00
• d1af1b5fef Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class. Jonathan Thomas 2012-08-15 17:27:14 -05:00
• 9b6d4dc4a1 Added some additional "duration" checks, to fix bugs with reading webm files. Jonathan Thomas 2012-08-12 02:14:15 -05:00
• be802dafb0 Added experimental AddEffect method to the frame object, to apply image effects Jonathan Thomas 2012-08-11 21:13:05 -05:00
• 1bbfa060cf Fixed a huge regression with PTS, that caused all sorts of issues with encoded videos, especially webm. Jonathan Thomas 2012-08-11 20:28:05 -05:00
• 7eeb8f7c80 Added a few new options Jonathan Thomas 2012-08-11 03:39:00 -05:00
• 1b1b84dde8 Added 2 additional options for SetOption, and split the preparing of streams and the writing header into separate methods. Jonathan Thomas 2012-08-11 03:19:52 -05:00
• 191d905299 Improved SetOption to recognize a few codecContext variables as well (such as g, qmin, and qmax) Jonathan Thomas 2012-08-11 02:59:03 -05:00
• 7f159b7189 Fixed python build install paths again Jonathan Thomas 2012-08-09 15:48:10 -05:00
• 2486cb87dc Testing new python install script Jonathan Thomas 2012-08-09 15:08:34 -05:00
• e983e447f1 Changed SONAME to 1 Jonathan Thomas 2012-08-09 11:01:49 -05:00
• fb9cc41ebf Added in cmake rules for SONAME Jonathan Thomas 2012-08-08 17:28:15 -05:00
• 597db2cc86 Simplied the cmake install scripts Jonathan Thomas 2012-08-08 12:36:52 -05:00
• 0dcc8fc7fe Adding a __init__.py python module, for the Debian packaging Jonathan Thomas 2012-08-08 01:13:57 -05:00
• 370a28905c Update cmake build scripts to install the DOC folder, after "make doc" is run Jonathan Thomas 2012-08-07 16:45:30 -05:00
• e41f6210d5 Fixed the cmake install files to correctly copy the header files Jonathan Thomas 2012-08-07 13:11:24 -05:00
• 58fff417d0 Merging branches, which accidentally diverged. Jonathan Thomas 2012-08-07 11:33:49 -05:00
• 98882df918 Fixed a bug in the cmake install file Jonathan Thomas 2012-08-07 11:32:43 -05:00
• d380292210 Removed unneeded rescaling, since the codec and stream always have the same frame rate Jonathan Thomas 2012-08-06 20:13:01 -05:00
• 363cb8f257 Commented out unused error string, which breaks ffmpeg 53 Jonathan Thomas 2012-08-06 17:13:05 -05:00
• 74d30cf7ee Fixed cmake files to install headers and binary library file Jonathan Thomas 2012-08-06 16:33:31 -05:00
• 72d6553f75 Added the ability to specify the image type and scale of any frame when calling the Save() method on a frame. This makes it easy to save any frame as any image type at any size image... very useful indeed. Jonathan Thomas 2012-08-05 16:43:09 -05:00
• 67dba0cd67 Fixed the audio resampling by adding a new class called AudioResampler, which maintains state between calls to the JUCE resampler. Maintaining state allows JUCE to remove the discontinuities between the frames, and removes all the pops and crackles. Jonathan Thomas 2012-08-05 15:17:37 -05:00
