mpv how to identify files?

[Selur]

Using mplayer once could use:

mplayer --identify "PATH to file"

to get detailed information about a file, is really useful especially for DVDs and Blu-rays.
Sadly when calling:

mpv.com --identify "PATH to file"

if get

Option --identify was removed: use TOOLS/mpv_identify.sh

so does someone know how to work around this on Windows where there are no shell scripts?

I guess that something like:

mpv.com --term-playing-msg="???" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config -- "f:\TestClips&Co\files\test.avi"

with the right 'term-playing-msg' might work, but I have no idea how build a proper string to replace the '???' does anyone know it's way around MPV enough to list all infos mpv can provide about a source?

okay, something like:

mpv.com --term-playing-msg="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}\ndWidth: ${dwidth}\ndHeight: ${dheight}\n\nSubtitles: ${sub}\n" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config -- "f:\TestClips&Co\files\test.avi"

seems to do the trick and 'mpc.com --list-properties' lists all the possible properties, now it's mainly a question of 'which properties are interesting' and staying inside the max length for a command line call.

calling:

mpv.com --term-playing-msg="Tracks: ${track-list}\nChapters:\n${chapter-list}" --vo=null --ao=null --frames=1 --quiet --no-cache --no-config dvd:// --dvd-device="F:\TestClips&Co\discs\DVDs\TestDVD"

I get:

Can someone tell me whether there is a way to get rid of those ' �{\alpha&HFF}➜ {\r}�' outputs or what to make of them?

apparently not: https://github.com/mpv-player/mpv/issues/7529

Can't you use ffprobe for extracting file info?

[Selur]

for single files: yes but for DVDs it's not really useful.
Atm. I'm using mplayer + ffmpeg + MediaInfo + tsmuxer + mkvinfo + vstrip in Hybrid.
I mainly used mplayer since I use it as preview player (and for auto cropping and chapter and cut point selection), since some folks keep pestering me about supporting mpv instead of mplayer I wanted to look into it. I figured out how I would incorporate mpv for preview, but just using it for preview and not like mplayer also for xvid encoding and DVD analysis and DVD input handling is simply not worth rewriting the code or adding the additional file size to Hybrid.
-> Since every time I look into mpv it either fails or they drop support for something I will simply give up on mpv for the time being. May be I'll look into it in a couple of years again.
(ffprobe isn't really that interesting since ffmpeg can do everything ffprobe does as far as I can tell and ffplay isn't interesting since from what I can tell it does not support some sort of slave mode to display inside another windows and be controllable by command line or ipc)

To gather mediainfo (mediainfo.dll + code or ffprobe,ffmpeg + code or something else) and preview could be completely separate processes.
So one code gathers data and shows them in UI, other code previews a filepath. Just curious why would you try to shell them as one process.

Sorry, must be my english.
Analysis and preview are separate processes. Still atm. adding mpv simply doesn't make sense.
Preview works fine as it is and mpv can't replace mplayer, so adding it just for preview isn't worth the hours of coding for me.
