[Bug] - Trying to upload a video/mp4 with binary encoding fails

[teophilus]

Current behavior:

$ file -I test_asset_02.mp4

test_asset_02.mp4: video/mp4; charset=binary

Desired behavior:

Trying to upload a video/mp4 with binary encoding fails, I used the same command for Jpegs and such and they work perfect.

Steps to reproduce: (app code and test code)

Upload an video/mp4 with binary encoding

Versions

Cypress: 3.5.0 , operating system: locally OSX but running against a production server (Unix), browser: Electron

Hi @teophilus

Thanks for submitting the issue!
Can you please provide the code snippet? It seems it should work, as binary is one of the supported encodings:

I have same issue, here's my code snippet:

.fixture('sample_video.mp4')
            .then(fileContent => {
                cy.get('#upload-video').upload({
                    fileContent,
                    fileName: 'sample_video.mp4',
                    mimeType: 'video/mp4',
                    encoding: 'binary'
                })
            })

But I'm getting different error.

I got it fixed by setting encoding to 'utf8'.

.fixture('bear.mp4')
            .then(fileContent => {
                cy.get('#upload-video').upload({
                    fileContent,
                    fileName: 'bear.mp4',
                    mimeType: 'video/mp4',
                    encoding: 'utf8'
                })
            })

Hello, in my case where I used mp4box library to have a check on video metadata before sending a video, the above workaround does not work. It produces wrong video metadata. The below workaround works:

• set encoding to base64 in cy.fixture()
• set encoding in cypress-file-upload .attachFile to base64.

            })

The upload not longer work with Cypress 7.3.0 and cypress-file-upload 5.0.7, all you need to do is to change from upload to attachFile.

Hello,
Thank you for this, however, I'm trying to upload large or small video files then accepted, in order to test the right error message. The following result is obtained:

for others this is what worked for me:

            cy.get('[data-testid="video-component-upload-dropzone-input"]').attachFile({

This works great for me, excluding uploading large video files

{ encoding: 'base64' }

What do you mean by large. Approximately how much large
