From 70243b5b76d5d0281f5459b9cfddd636c8cd1ef0 Mon Sep 17 00:00:00 2001 From: nin0dev Date: Sun, 23 Jun 2024 12:21:01 -0400 Subject: [PATCH] Updated videobundler to add concurrency and caching --- videobundler/README.md | 5 +- videobundler/main.py | 159 ++++++++++++++--------------------------- 2 files changed, 56 insertions(+), 108 deletions(-) diff --git a/videobundler/README.md b/videobundler/README.md index 3b317448..54d24caf 100644 --- a/videobundler/README.md +++ b/videobundler/README.md @@ -22,6 +22,5 @@ Takes 2 input streams, downloads them, and spits out a combined file. ## Endpoints - `/`: Will return `{success:true}` if alive. -- `/merge?id=VIDEO_ID&audio_itag=AUDIO_ITAG&video_itag=VIDEO_ITAG`: Starts the merging process. ID is the youtube video ID, and itags are self explanatory. As a response, you will get a job ID that you will be able to use in future requests to query the video or its status. When this process is finished, the inactive autodelete counter will start, which will allow you to fetch the video until the countdown is over. -- `/get?id=JOB_ID`: Queries a merged video and sends it to you. If the video is successfully and fully merged you will get a 200 response with a video. However, if it isn't finished, you will get a `success: false` 404 response. If the video indeed exists and is sent to you, the get autodelete counter will start, which will allow you to fetch it until this countdown is over. -- `/check?id=JOB_ID`: Queries a merged video's status. If the video is successfully and fully merged you will get a 200 response with `success:true`. However, if it isn't finished, you will get a `success: false` 404 response.
