Hi Everyone,
I’m calling the veo 3.0 model but when I try to download the video that I get as a response I must be doing something wrong beacuse the mp4 storage path is empty, it has 0 bytes, and nothing plays on the mp4 player. So it seems it must be a problem of how im downloading the ai.filesdownload() but can’t quite get it solved:
Not sure if anyone has faced a similar issue even if with a different model, and how I could narrow this down. I explain below:
- Im calling the veo 3.0 as follows:
// Generate video using Veo 3 and Polling until video ready
console.log(`Calling Veo 3 API for ${formatName} video...`)
let operation = await ai.models.generateVideos({
model: "veo-3.0-generate-preview",
prompt: videoObject.prompt,
config: {
aspectRatio: formatData.aspectRatio
},
})
console.log('Video generation operation started:', operation.name)
- Then im polling until the video is ready
let pollCount = 0
const maxPolls = 60 // Maximum 10 minutes (60 * 10 seconds)
while (!operation.done && pollCount < maxPolls) {
console.log(`Waiting for video generation to complete... (poll ${pollCount + 1}/${maxPolls})`)
await new Promise((resolve) => setTimeout(resolve, 10000)) // Wait 10 seconds
operation = await ai.operations.getVideosOperation({
operation: operation
})
pollCount++
}
if (!operation.done) {
throw new Error('Video generation timed out after 10 minutes')
}
if (operation.error) {
throw new Error(`Video generation failed: ${operation.error.message || 'Unknown error'}`)
}
console.log('Video generation completed successfully')
- Then I’m getting the generated video
// Get the generated video
const generatedVideo = operation.response?.generatedVideos?.[0]
if (!generatedVideo?.video) {
throw new Error('No video data in response')
}
console.log('Generated video file:', generatedVideo.video)
Console log above always shows success with the following response, which I assume that means the above is processing correctly:
"Generated video file: {\n uri: \"https://generativelanguage.googleapis.com/v1beta/files/8bem4xshl3ac:download?alt=media\",\n videoBytes: undefined,\n mimeType: undefined\n}\n"
- Then Im downloading the generated Video
// Download the video file
const videoFile = await ai.files.download({
file: generatedVideo.video
})
Then I work accross other sections of the component to give a storagePath and a name to the VIdeoFile as follows , to upload to S3/Supabase Storage:
// Preparing variables to save the Video in S3/Supabase Storage
const timestamp = Date.now()
const randomId = Math.random().toString(36).substring(2, 15)
const fileName = `ai-video-${formatName}-${timestamp}-${randomId}.mp4`
const storagePath = `ai-generated-videos/${fileName}`
// Getting user's bucket for storage
const { data: userBucket, error: bucketError } = await supabaseAdmin
.from('content_buckets')
.select('bucket_name')
.eq('user_id', user.id)
.limit(1)
.single()
if (bucketError || !userBucket) {
throw new Error('User bucket not found')
}
// Upload to Supabase storage
const { data: uploadData, error: uploadError } = await supabaseAdmin.storage
.from(userBucket.bucket_name)
.upload(storagePath, videoFile, {
contentType: 'video/mp4',
upsert: false
})
if (uploadError) {
throw new Error(`Failed to upload video: ${uploadError.message}`)
}
console.log('Video uploaded successfully:', uploadData.path)
//Then I get a sigend URL for display on FrontEnd
// Generate signed URL
const { data: signedUrlData } = await supabaseAdmin.storage
.from(userBucket.bucket_name)
.createSignedUrl(storagePath, 3600) // 1 hour expiry
The problem is that when I load the signed URL I see that the file on that path is empty
Basically I’ve banged my head for the last 4-5 days and tried pretty much everything.
Any help super appreciated!
