Script to quickly convert and crop videos from within mpv

#README:

This script for mpv intends to offer the fastest and simplest way to convert parts of a video—while you’re watching it and not really more work intensive than making a screenshot. A short demonstration: https://d.maxfile.ro/omdwzyhkoa.webm

##Installation:

You need:

  • yad (at least 0.26) (AUR)
  • mpv (at least 0.4)
  • notify-send (optional, to send a notification when the encode is done) (to be found in libnotify on Arch)
  • mkvmerge (optional, for stream copy)
  • imagemagick (optional, for gifs)
  • linux

Install it by putting the script into ~/.config/mpv/scripts/ or ~/.mpv/scripts/ (mpv 0.8+) and ~/.config/mpv/lua/ ~/.mpv/lua/ respectively (mpv 0.4 through 0.7)

##Usage:

alt + w activates the script. First activation marks one end of the clip, the second one the other, order does not matter.

Cropping doesn’t really work well with the OSC.

##Configuration:

Configuration works in the same way as configuring the OSC does. You can bind it to another hotkey in your input.conf with <key> script_message convert_script and set some options in mpv/lua-settings/convert_script.conf or with --script-opts (mpv 0.7 and earlier: --lua-opts)

audio_bitrate
Default: 112
In kbps. The script tries to compensate for audio when going for a file size limit (2pass). You’ll only need to change this if you modify mpv’s audio encoding options, for example with oacopts-add=qscale=0 in the [encoding] section of your mpv.conf (in which case this option would need 64). 

bitrate_multiplier
Default: 0.975
To make sure the file won’t go over the target file size, set it to 1 if you don’t care.

output_directory
Default: $HOME
Where the script saves your converted files. 

use_pwd_instead
Default: no
Use your working directory as the output directory. Overrides output_directory.

use_same_dir
Default: no
Use the directory of the original video file. Overrides output_directory.

libvpx_threads
Default: 4
Number of threads to use for encoding, libvpx only because it apparently doesn’t have auto detection. 

crop_individually
Default: yes
Whether you want only the last crop argument to count—no—or you want to crop all segments individually—yes. In that case the final video will inherit the aspect ratio of the first segment. 

libvpx_options
Default: --ovcopts-add=cpu-used=0,auto-alt-ref=1,lag-in-frames=25,quality=good
Higher quality at the expense of processing time.

legacy_yad
Default: no
If you don’t want to upgrade your yad. Features like appending segments won’t be available. 

libvpx_fps
Default: --oautofps
FPS settings (or any other settings really) for libvpx encoding. Set it to --ofps=24000/1001 for example. 

Warning: Some of these options aren’t very robust and setting them to bogus values will break the script.

This script crashes when yad returns numbers with a comma as decimal mark. Lua's tonumber() will return nil when you feed it a number separated by a ','
a shitty fix: insert

yad = string.gsub(yad, ',','.')

on line 545

Launching yad with LC_NUMERIC=C should solve that, I guess?

Same issue now with tonumber(yad_table[1]), uses of yad_table[6], and possibly others.

Encoding fails when playing a file with non-48 kHz audio (e.g. 44.1 kHz) and encoding to WebM with audio included: [ffmpeg] libopus: Specified sample rate 44100 is not supported

(Note that the solution is not as simple as specifying --oacopts-add=ar=48000, you have to insert a resample filter e.g. --af=resample:srate=48000)

Could you please convert it to a true repository? I want to package it, and would like to submit a PR.

Also, a permissive license would be nice.

I'm getting this error when trying to convert to webm(vp8)

Error parsing option ovc (option not found)  0.000
Setting command line option '--ovc=libvpx' failed.

Any idea why?

@lop125 I was told on IRC that encoding is disabled in the latest release by default. You need to recompile with encoding enabled. They also told me it was enabled again in the upcoming version.

If you use nix(os) I’m going to incorporate that change soon.

Can you please make a script that just lets me draw a rectangle to crop the video to a custom portion just for playback? I don't want to save/convert the cropped video, I just want to keep watching the video, but cropped to a specific portions.

Like pressing Shift+C would bring up the rectangle tool, and then on release crop the video, and pressing Shift+C again would reset the crop.

@horusra I've just started a project to do just that here. Still needs work... but the core cropping functionality is there.

I’ve added the transient hint to the notify-send command, so the calls won’t stack – it can only hold about 20 messages and then new messages are not shown until you clean the messages by hand.
Apparently, I cannot create a pull request for a gist, but you can copy the change from my fork.

How would you edit this to default to using -c:a libvorbis for the audio codec?

I seem to get the following regardless of what I try when going to convert a video

The mpv API has changed in 0.26.0, some of the options have been deprecatad;

Here’s a patch that fixed it for me. As far as I understand, these options already existed in earlier versions:

As an aside, I can’t do a pull request. Maybe it is time to convert this gist to a normal repo?
