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.
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.

1e5cffd6db Added the initial API of the FFmpegWriter class, and tweaked the build scripts and reader class. 2012-07-12 15:55:41 -05:00

0e233be34e Added new unit tests for FFmpegReader, which tests actual pixel color values against a test video on 2 different frames. Also, made Seek() method private. 2012-07-09 01:44:36 -05:00

dfae7825ca Refactored FFmpegReader code a bit, fixed many, many memory leaks, and many valgrind errors. Now the memory seems very stable, and the seeking and stream walking seems very solid. 2012-07-08 23:26:44 -05:00

21aa4d6b01 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

fde25cec5a Lots of experimental changes with the FFmpegReader, and caching of packets. 2012-07-02 00:51:10 -05:00

403c7e512e Fixed 2 bugs related to audio samples. Each frame can now determine it's own # of samples, due to some sample rates not being divisible evenly into some frame rates. Also, a bug was fixed that injected a bad sample into a frame's samples, when a frame received samples from multiple audio packets. 2012-02-26 16:40:53 -06:00

da289f93bf Fixed a bug where audio was not being resampled to the correct sample format. Also fixed a bug where the audio buffer was not being incremented correctly, and it was duplicating audio samples. There are still a few audio bugs, but it's mostly working now. 2011-12-18 02:29:34 -06:00

f00c4206be Added a method to get the average # of frames over the initial 5 seconds of video, and adjust an invalid framerate, which sometimes FFmpeg detects. Also, a Reader only initializes it's default values 1 time, and only checks frame rate 1 time, regardless of how many times your Open() and Close() the reader. 2011-12-15 16:11:48 -06:00

ade29c7d68 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

26083f27b7 Fixed a rounding error on mapping audio samples to frames. Also adjusted the sample rate on the frame.Play() method to 48khz. 2011-10-26 14:34:14 -05:00

43fd6c33d0 Some major refactoing of the FFmpegReader, to allow for audio and video packets that are out of order. 2011-10-24 08:22:21 -05:00

1faa168fb3 Began to refactor the FFmpegReader to correctly save the audio samples with the correct frame. 2011-10-14 09:47:05 -05:00
