--- tags: cofacts, meeting note GA: UA-98468513-3 --- 20240304 會議記錄 ===== :::info - [所有會議記錄](https://g0v.hackmd.io/@mrorz/cofacts-meeting-notes/) - 線上出席: - https://gather.town/app/z3x18KQFgZCX8MeZ/cofacts ::: ## :potable_water: Release pipeline ### :star: Released to production #### :globe_with_meridians: Site https://github.com/cofacts/rumors-site/releases/tag/release%2F20240304 - marcussfu++ ## CCPRIP ### [Op] Transcript spam > nonumpa > https://g0v.hackmd.io/vKCvrqSQTlm7GEx9MAXGaw?view#op-Transcript-spam-處理 contributor 在 snapshot update 時更新 - 可能會有兩個人的 contribution 會記成同一個時間 [name=nonumpa] - 像 google doc 所以 ok [name=mrorz] ### [Comm] article group 收尾 > nonumpa ### [Comm] Thumbnails for video and audio > https://github.com/cofacts/rumors-api/issues/326 > [name=mrorz] - 上次測的問題:忘記升級 media manager package,升級後可以傳送 - 不會等轉檔完才回 LINE,還不錯 - 但仍然有問題:佔用 CPU - 其實轉檔沒有必要在主 API server 處理 - 可以考慮改在 cloud run 做,或 - Alternatives 1. [Cloudflare Stream](https://developers.cloudflare.com/stream/) - 儲存費用每月付 ![](https://s3-ap-northeast-1.amazonaws.com/g0v-hackmd-images/uploads/upload_7f2a3f0cbc63b4d3c7200e0893262431.png) - 假設每個影片 1min,Cofacts 已經有 9214 video / audio --> 9000 min,$50/mo 的範圍 - 播放費用另計,但如果只有查核協作者可以播放的話就會很省 - 目前看起來,關於 thumbnail: - thumbnail 好像不算錢,只有靜止的跟 gif(限 15s 內、fps 限制 1~15) - thumbnail 是 request 來才會即時生成,如果是 gif 的話可能要生數秒鐘,產出十幾 MB 的 gif 送到瀏覽器 - thumbnail 可以指定開始播放的時間,但無法調整播放速度 - 另外關於影片檔案: - 檔案可以做 signedUrl,所以可以在 rumors-api 產出 signed URL 吐在 attachmentUrl 裡頭,也可以在裡面放 thumbnail URL - 可以生成指定長度的 clip 限制播放時長 - 要用的話,一般的做法: - 訊息列表 thumbnail: 用 cloudflare 的 gif thumbnail - 未登入造訪訊息內頁 preview: 用 cloudflare 的 iframe stream player 播放 30s clip - 登入後的使用者可以拿到 original,用 cloudflare 的 iframe stream player 播放原長度影片 - 更省的做法: - 訊息列表 thumbnail: 用 cloudflare 的靜止 thumbnail(jpg,較小) - 未登入造訪訊息內頁 preview: 用 cloudflare 的 gif thumbnail 15s (不用錢,但應該要生一陣子) - 登入後的使用者可以拿到 original,用 cloudflare 的 iframe stream player 播放原長度影片 - 附加好處 - 可以透過 cloudflare retrieve video detail API 拿到影片時長 - 因為有 on-the-fly 的 thumbnail URL 可以用,因此未來如果接了 google video intelligence API 偵測 shot changes,甚至可以做到列出影片分段截圖的功能,對查核影片會超級方便——點擊截圖跳到那個分段、對截圖右鍵來用瀏覽器內建功能以圖找圖等等。 2. Google Transcoding API - 指定要轉的解析度、轉完放哪裡。轉換[算便宜](https://cloud.google.com/transcoder/pricing) (0.015/min for SD thumbnail),儲存就是 GCS - 直接有 sprite sheet! https://cloud.google.com/transcoder/docs/how-to/generate-spritesheet#generate_image_periodically - Google lens 可以只選一幀出來 ![](https://s3-ap-northeast-1.amazonaws.com/g0v-hackmd-images/uploads/upload_05dc6db86196cb855046859d5e151d3d.png) - 跟 bucket、cloud function 串在一起: https://cloud.google.com/use-cases/video-on-demand?hl=en#features - 輸出檔案: - Thumbnail 放 360p 影片, 前 20s、15fps 在 [client side `<video>`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/defaultPlaybackRate) 加速到 2x - Preview 放 sprite,每隔幾秒一格 - 形式 - media manager 上傳原始檔案之後,GCS bucket file change 觸發 cloud function - cloud function 呼叫 transcoding API (batch mode) - 檔案回存到同一個 GCS bucket file 資料夾底下,未來 rumors-api 與 media manager 可以讀得到該 variant - 缺點 - 沒有辦法拿影片長度之類的 metadata,但這可以另外呼叫 ffprobe 搞定 - 目前沒登入就無法看影片 [name=nonumpa] - 上傳色情影片,沒登入就看不到,預覽圖下 google 抓到的機率更大 [name=nonumpa] - 可能就是要上 video intelligence API [name=mrorz] - 模糊化處理,登入才能檢視? :::success - 朝 2 進行 - 寫 design doc - 選項紀錄至 https://g0v.hackmd.io/aJqHn8f5QGuBDLSMH_EinA?both#Video-summarization-for-thumbnails - Updated issue https://github.com/cofacts/rumors-api/issues/326 ::: ### [Op] Google 非營利 - 回信後尚無回音 ## User organization and CoC > https://hackmd.io/ktxqGDX4S4iuBd1MoZqDmQ?view#Cofacts-Editor-Organization-%E6%A9%9F%E5%88%B6 - Organization qualification: 不另外要求 qualification - 但可以想一想,自己無法接受什麼樣的組織來申請 organization? - 更嚴格要求 CoC? - For all contributors:反騷擾原則 - https://www.facebook.com/legacy/notes/2046634208901731/ - 參考 https://hackmd.io/1U4u6d81QCqgtYriyC5kOA?view#II-COSCUP-CoC-%E4%BF%AE%E8%A8%82%E5%88%86%E4%BA%AB---%E9%9D%A2%E5%B0%8D-MeToo-%E7%A4%BE%E7%BE%A4%E8%A9%B2%E5%A6%82%E4%BD%95%E5%9B%A0%E6%87%89 - 因為比較顯眼,所以要求要比一般協作者多: - 要提供錯誤回報更正機制 - 違反 CoC 的話嚴重可能撤銷 organization,全部變回一般查核協作者的樣子 - Progression: CoC draft --> 社群討論是否有意見 --> 公告 apply 到網站內容、小聚 etc - 之後實作 organization、處理都有依歸 [name=mrorz] - 4 月底 [name=bil] - 產出內容避免國籍、性別、種族、年齡歧視 - 參考 OCF - 處置: 內容 --> 修改文字、移除部分段落 or 全篇移除 :::success Bil draft CoC ::: ## 小聚籌備 - [ ] 日期:3/24 (日) - [ ] 食物:要自己清,垃圾桶不能丟 - [ ] 場地:新北青職基地 1F - 一定要 20 人以上,最多坐 60 - 6 個桌子、20 張椅子、麥克風、投影幕、筆電 - [ ] 時間: - 活動時間:14:00 - 17:00 - 時間分配 - 2:00 - 2:20 開場 - 影片 - Slido 暖身 - 2:20 - 2:40 引導註冊網站、介紹評價現有回應 - 2:40 - 2:50 實作評價 - 2:50 - 3:10 介紹補充資訊 - 3:10 - 3:40 實作補充資訊、自我介紹、休息 - 3:40 - 4:10 介紹撰寫新回應 - 4:10 - 4:40 實作撰寫新回應 - 4:40 - 5:00 介紹分類、RSS、合照 - [ ] 投放目標: - 推播日:3/18 (一)推播 - 推播日之前:新北志工優先報名 - 目標:雙北、桃園? - ![](https://s3-ap-northeast-1.amazonaws.com/g0v-hackmd-images/uploads/upload_aff7fe2b732675b4b90f1e90a56fd071.png) - 14 萬人收到、萬分之2報名率 --> 開 30~40 人、預期 20 人到場? - Ref: [past click through rates](https://docs.google.com/spreadsheets/d/1XjEQZ9esNKfkGd8XYd1p3E8DTgB0f5QPDl5ghf-JxE0/edit#gid=0) - [ ] KKTIX:https://cofacts.kktix.cc/events/cofactseditor41 - [ ] 誰會來呢:bil, mrorz, nonumpa - [ ] 記得帶:貼紙、環保杯 - [ ] LINE 文案 Cofacts 要來到新北市舉辦志工培訓啦,三鐵共構板橋站,交通超級方便唷! 地址:新北市青職基地 / 新北市板橋區民權路170號1樓 時間:03月24日(日)14:00-17:00(會很準時開始)請記得攜帶筆記型電腦喔! 活動報名:https://cofacts.kktix.cc/events/cofactseditor41 - [ ] VOOM 發文 ## 協會 About 頁面英文修改 > Source: https://g0v.hackmd.io/6tCmrXsyS3WEGgC_bMcd9w#-Site ChatGPT 建議:https://chat.openai.com/c/50d6faed-c65a-4092-9741-0e4b621b2896 > Cofacts originated as an open-source project in 2016.
