Consider other backends

[Poikilos]

Overview of backends

• av (PyAV, which supercedes pyav module): "PyAV is a Pythonic binding for the FFmpeg libraries. We aim to provide all of the power and control of the underlying library, but manage the gritty details as much as possible."
  • may not be very portable. See https://pypi.org/project/av/
  • Found some examples using GitHub search: "import av" NOT "import ava" NOT "import avd" NOT "import ave" NOT "import avi" NOT "import avl" NOT "import avm" NOT "import avn" NOT "import avo" NOT "import avp" NOT "import avt" language:Python
• cv (OpenCV)
• mpv
• custom MPEG2-TS backend for av: https://github.com/huiminlim/pyav-playground

For preview panel

• mpv-live-filters: Add and remove ffmpeg filters during playback
• pyvidplayer2
• RH-Video-Player if license gets added: Please add license so people have permission to use it RidwanulHaque111/RH-Video-Player#1
• https://github.com/PaulleDemon/tkVideoPlayer based on av (no audio)
• avplayer: no audio, main.py doesn't demonstrate seeking. See also When using tk, "The image queue is full. Drop the current frame" occurs on every frame osom8979/avplayer#3
• pymontage (uses av): https://github.com/xndcn/pymontage
• h264_iframes Detects (and can manipulate) i-frames of H.264 (the frames which don't require other frames to decode)
• Consider tkpixels pythonpixels subclass using PhotoImage #18

For rendering

• AVIDemux: Can make new GOPs to split when not on keyframes (like avcut but that is a smaller project and mkv only)

Both preview and rendering

• https://github.com/Zulko/moviepy (uses imageio_ffmpeg; optionally integrates with pygame)
• https://github.com/ozmartian/vidcutter (uses mpv and ffmpeg)
