Selur's Little Message Board - How to identify files with MPV,...

From time to time I play with the thought to drop mplayer/mencoder in favor for mpv.
MPlayer atm. is used in Hybrid to:

analyse the input
provide crop preview
provide normal Preview
provide subitle Preview
handle DVD input when neither Avisynth nor Vapoursynth are used

So starting with the 'analyse the input', I tried to figure out how to get mpv to report data about the input.
To collect data about normal files one can use:

Code:
mpv.com --term-playing-msg="XXX" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config "PATH TO FILE"

To collect data about DVD one can use:

Code:
mpv.com --term-playing-msg="XXX" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config dvd://[title] --dvd-device="F:\TestClips&Co\discs\DVDs\TestDVD"

To collect data about Blu-rays one can use:

Code:
mpv.com --term-playing-msg="XXX" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config bd://[title] --bluray-device="F:\TestClips&Co\discs\BDs\TestBD"

the important part now is on how to specify the XXX
Here's how it looks atm:

Code:
"Filename: ${filename}\nPath: ${path}\nStart: ${stream-start}\nEnd: ${stream-end}\nLength: ${stream-length}\nDemuxer: ${demuxer}\nContainer length: ${length}\nChapters: ${chapters}\nEditions: ${editions}\nTitles: ${titles}\nDuration: ${duration}\nAudio: ${audio}\nAudio bitrate: ${audio-bitrate}\nAudio codec: ${audio-codec}\nAudio codec name: ${audio-codec-name}\nVideo: ${video}\nAngle: ${angle}Video bitrate: ${video-bitrate}\nVideo codec: ${video-codec}\nVideo format: ${video-format}\nVideo aspect ratio: ${video-aspect-override}\nContainer fps: ${container-fps}\nWidth: ${width}\nHeight: ${height}\nDisplay Width: ${dwidth}\nDisplay Height: ${dheight}\n\nSubtitles: ${sub}\nTracks: ${track-list}\nChapters:\n${chapter-list}"

here a bit more readable: ('\n' replaced by new line)

Code:
Filename: ${filename}

Path: ${path}

Start: ${stream-start}

End: ${stream-end}

Length: ${stream-length}

Demuxer: ${demuxer}

Container length: ${length}

Chapters: ${chapters}

Editions: ${editions}

Titles: ${titles}

Duration: ${duration}

Audio: ${audio}

Audio bitrate: ${audio-bitrate}

Audio codec: ${audio-codec}

Audio codec name: ${audio-codec-name}

Video: ${video}

Angle: ${angle}Video bitrate: ${video-bitrate}

Video codec: ${video-codec}

Video format: ${video-format}

Video aspect ratio: ${video-aspect-override}

Container fps: ${container-fps}

Width: ${width}

Height: ${height}

Display Width: ${dwidth}

Display Height: ${dheight}

Subtitles: ${sub}

Tracks: ${track-list}

Chapters:\n${chapter-list}

see: https://mpv.io/manual/master/#property-expansion and https://mpv.io/manual/master/#property-list

atm. I have no clue how to get mpv to:

list all the available titles on a DVD/Blu-ray
get mpv to output something more readable, see: https://github.com/mpv-player/mpv/issues/7529

Ps.: this is mainly to a let others know how this could be done and also keep track of what I found so far, so that I don't have to search my notes on where I was,..
