- Fill in the rest of the FFmpeg test output code for testing so it actually properly outputs data. - Improve the main video subsystem to be a bit more optimal and automatically output I420 or NV12 if needed. - Fix audio subsystem insertation and byte calculation. Now it will seamlessly insert new audio data in to the audio stream based upon its timestamp value. (Be extremely cautious when using floating point calculations for important things like this, and always round your values and check your values) - Use 32 byte alignment in case of future optimizations and export a function to get the current alignment. - Make os_sleepto_ns return true if slept, false if the time has already been passed before the call. - Fix sinewave output so that it actually properly calculates a middle C sinewave. - Change the use of row_bytes to linesize (also makes it a bit more consistent with FFmpeg's naming as well)
