Can't get plug-in to work, despite reSnap working

[alexnegron]

Hi, hope to get the plug-in working, looks awesome! Trying to run this on a Mac M1. I believe I set up reSnap properly since calling ./reSnap.sh (tablet usb-connected) pulls up a capture of the tablet's screen in XQuartz.

Here's the error code from Obsidian.

plugin:obsidian-remarkable:5846 Found CM editor

Given the errors in lines 177, 178, and 188 I'm led to believe it has something to do with lz4, feh, and ffmpeg? Calling which for each of these gives: /opt/homebrew/bin/lz4 /opt/homebrew/bin/feg /opt/homebrew/bin/ffmpeg

Not sure if its a path issue with these guys, or something else entirely.

Hmm, I'm not immediately sure how that's happening. Should probably work, but just to make sure, what's the output of command -v ffmpeg in your shell?

One thing you could maybe try is changing this line https://github.com/cobalamin/obsidian-remarkable/blob/master/main.ts#L96 in your local copy to const process = spawn(executable_path, args, {"shell": "/bin/bash"});.

Hi, sorry, haven't been up to date with things and sort of tabled RM stuff. Thanks for the help!

command -v ffmpeg returns /opt/homebrew/bin/ffmpeg

I made the suggested change now to the main.js file (this is the new one for the 1.1.1 release, installed via BRAT). The error I get now is

Uncaught (in promise) Nonzero exitcode.

Just wanted to pop a note here and say that I'm also having this problem. "Could not insert your rM drawing! Is your tablet connected and reachable at the configured address?"

I can confirm that everything works fine when I run reSnap manually via the terminal.

Any ideas?

[alexnegron]

I managed to fix the issue I was having. I'm not sure exactly why it works, or if it generalizes to the issue you may be having, but I'll explain what I did.

• I did a fresh reinstall of feh, ffmpeg, lz4. For lz4, I freshly installed it both on my remarkable and my computer. I was suspicious of a path issue, so figured this was a good first step.
• Verified that reSnap worked manually via terminal; running the script opened whatever was on the tablet in XQuartz.
• Attempted to insert the image into Obsidian using the plugin. Same error: "Could not insert your rM drawing! Is your tablet connected and reachable at the configured address?"
• Obsidian developer mode told me the issue was in the reSnap.sh file itself, saying that the commands in lines 166, 167, and 177 were not found.
• Ok, so this is what made me think it was a path issue. For whatever reason, when called from inside the plugin itself, reSnap wasn't accessing lz4/ffmpeg/feh properly. With no smart way to fix this, I literally just put in the absolute paths. Specifically, I changed lines 160-178 to:

FFMPEG_ABS="$(command -v /Users/alexnegron/opt/anaconda3/bin/ffmpeg)"
LZ4_ABS="$(command -v /opt/homebrew/bin/lz4)"

echo "$FFMPEG_ABS"

# read and compress the data on the reMarkable
# decompress and decode the data on this machine
ssh_cmd "$head_fb0 | $compress" |
  "${LZ4_ABS}" -d |
  "${FFMPEG_ABS}" -y \
    -f rawvideo \
    -pixel_format $pixel_format \
    -video_size "$width,$height" \
    -i - \
    -vf "$filters" \
    -frames:v 1 "$output_file"

• There are 2 notable changes I made: (1) I put in the absolute paths to ffmpeg and lz4, and (2) I deleted lines 175-178 in reSnap.sh. At first, I only did (1). When I would try inserting into Obsidian, it would work, no error was thrown, but the image would launch in XQuartz, get inserted into a rm file folder in Obsidian, but not get put into the actual note. Have no idea why. But deleting 175-178 solved this issue, and everything worked from there.

Hope this helps! Sorry if this was a bit hacky, I have very little idea what I'm doing with all this; sort of just tried different things until it finally worked.
