Could not open codec 'png': Unspecified error

[JannikRitscher]

Compiled from scretch on amd64. Following error occures:

Bytes ripped succesfully Byte length: 311 Binary ripped succesfully [src/etcher.rs:359] final_frame = 1 Etching frame ended in 664us Instructions written Etching frame ended in 1914us Embedding thread complete! [png @ 0x560d527d6140] Specified pixel format yuv420p is invalid or not supported Could not open codec 'png': Unspecified error Video embedded succesfully at output.avi Etching video ended in 4049us

No video is created. Any help on this error?

Might have something to do with the file being very small. Try to use custom settings with 144p resolution and see if it works ?

Try updating, I made it fall back to what should be a widely used codec

[JannikRitscher]

First of all, thanks a lot for looking into this. Unfortunately the fixed made things worse for me. I updated to the new codebase, recompiled, but now I get the initial error message every time I try to embed a file. Size of the files doesn't affect this behavior. Tried many different files, ranging from 1MB, over 5MB, 20MB up to 100MB.

Anything I can provide you with to help diagnosing this bug?

Welcome to ISG (Infinite Storage Glitch)
This tool allows you to turn any file into a compression-resistant video that can be uploaded to YouTube for Infinite Storage:tm:

How to use:
1. Zip all the files you will be uploading
2. Use the embed option on the archive (THE VIDEO WILL BE SEVERAL TIMES LARGER THAN THE FILE, 4x in case of optimal compression resistance preset)
3. Upload the video to your YouTube channel. You probably want to keep it up as unlisted
4. Use the download option to get the video back
5. Use the dislodge option to get your files back from the downloaded video
6. PROFIT

> Pick what you want to do with the program Embed
> What is the path to your file ? /root/out/out.txt

I couldn't figure out a weird bug that happens if you set the size to something that isn't a factor of the height
If you don't want the files you put in to come out as the audio/visual equivalent of a pipe bomb, account for the above bug

> You can use one of the existing presets or custom settings Optimal compression resistance

I guess your PC just doesn't have png as a codec. We'll need to find a replacement for it

Just to let you know, i was running debian before. Switched to WSL on Windows using the instructions from the newly added Dockerfile and it works just fine.
