a8fa5a91d2 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

e264d4fcab Fixed a really huge audio issue, related to audio timestamps, gaps, and also mono vs stereo issues. This is the best audio support I've accomplished thus far. =) 2012-12-03 04:51:17 -06:00

d3ef1fac13 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

547a0dbc63 Improved the flush_encoders method to not raise errors if it encounters errors encoding NULL AVFrames. 2012-11-18 10:45:16 -06:00

4a96a3b745 Fixed an invalid audio alignment settings on avcodec_fill_audio_frame, which was crashing everything on newer versions of ffmpeg. 2012-11-17 16:10:01 -06:00

bf05afbfa7 Fixed the flush_encoders method to support older versions of FFmpeg 2012-11-17 03:13:00 -06:00

dbeb8d1c14 Only use avcodec_encode_video2 if FFmpeg major version is 54 2012-11-17 02:47:48 -06:00

d6d885982c Better detection of av_err2str, by using it's macro name 2012-11-17 02:17:38 -06:00

51ef59a8a4 Removed some unneeded code 2012-11-16 17:17:55 -06:00

8fb94cc123 Updated the FFmpegWriter to use compiler #IF commands to be compatible with older and newer versions of FFmpeg. This is still a work in progress, but many of the newer commands are now being protected. 2012-11-16 17:15:44 -06:00

bff37d0072 Added in openMP code to improve performance on the timeline layer merging, which is very CPU intensive. 2012-11-12 17:21:21 -06:00
Jonathan Thomas
5b77abdf27 The timeline classes are finally working correctly, and have the following features: 
1) Layers (unlimited # of layers)
2) IN, OUT, and Position (time)
3) X, Y offset
4) Alpha
5) Rotation
6) Transparency + compositing + overlays

6e9f2a6a9b Changed audio and video PTS to start at 0, and it fixed the final issues I have had with generating valid videos in multiple codecs. 2012-10-28 23:38:24 -05:00
Jonathan Thomas
7dd94a02e4 Added code to flush the encoders, and also write the final frame's audio samples 2012-10-28 03:35:50 -05:00
Jonathan Thomas
60ffebe1fe Replaced avcodec_encode_audio with avcodec_encode_audio2, and completely redid the way PTS values are calculated and set. Another nice improvement! 2012-10-27 21:36:08 -05:00

bf93f6941e Fixed some major issues with the FFmpegWriter, which was not setting the correct PTS values 2012-10-26 17:15:17 -05:00

5fcead37f2 Added frame counter to writer class, to help generate a valid PTS 2012-10-26 02:11:39 -05:00
