av 0.5

• Ported read_audio_bin() to pure C, match parameters with read_audio_fft()
• Fix total_time parameter in av_audio_convert() to account for start time
• Unit test now uses CPU time instead of elapsed time (BDR)
• Added start_time and end_time parameters to read_audio_fft()
• Rename av_video_info to av_media_info
• Minor tweaks to configure script

av 0.4

• Windows/MacOS: CRAN binary packages now ship with ffmpeg 4.2.2 + drivers: vorbis, vpx, ogg, lame, xvid, x264
• Removed forced keyframes (gop_size) when encoding video from graphics or PNG images. This reduces output video size, hopefully no major quality regressions.
• New functions for audio! read_audio_fft() and read_audio_bin()
• New method plot.fft_data() for spectogram, e.g: plot(read_audio_fft('sample.mp3'))

• New parameters channel and sample_rate in av_audio_convert()

av 0.3 (2019-08-21)

• Input can now contain video, i.e. multiple images per file. Previously we would only read a single image from each input file, but now we read all of them.
• Major refactoring to suppor the above, hopefully no breakage.
• New functions av_video_convert() and av_audio_convert()
• New function av_video_images()
• Switch to R_UnwindProtect to implement cleanup on exit
• Test, tests, tests, so many tests.
