Veebiteenuse analüüs

Kirjeldus

Team Echo on kooli videosalvestuste mahamängimise veebirakendus. Selle abil konverteeritakse olemasolevad flash videod mp4 formaati, et seda oleks hea ja mugav meie veebirakenduses maha mängida. Selle boonuseks on sujuv ja probleemivaba salvestuste vaatamine, ning vanade salvestuste kätte saamine kui tulevikus echo360 tarkvara uueneb. Salvestused on kategoriseeritud kooli ja aine alusel. Salvestuste vaatamiseks pole vaja kasutajat, kuigi redigeerimiseks/lisamiseks on vaja.

Must have

Video konverteerimine
Kategoriseerimine EIK ainete alusel
Video striimimine meie veebiliides
Videode lisamine / eemaldamine
Logi kirjete kogumine
mp4 exportimine

Nice to have

Timestamp ja nende avalik kommenteerimine salvestusele
Konveteerimise progress
Kategoriseerimine Kooli ja aine alusel
Kooli kasutajaga sisselogimine
Videote otsing aine/õppejõu alusel
Saab vaadata playlist alusel

XML

Miks ei leia siit xml failist CDATA kirjeid?

Sest, CDATA ei anna midagi juurde xml masin lugemisele. Sama hästi võiks problemaatilised märgid asendada vajalike paomärkidega mis oleks ka palju turvalisem.

 ==Veebiteenuse analüüs==
 === Kirjeldus ===
+Team Echo on kooli videosalvestuste mahamängimise veebirakendus. Selle abil konverteeritakse olemasolevad flash videod mp4 formaati, et seda oleks hea ja mugav meie veebirakenduses maha mängida. Selle boonuseks on sujuv ja probleemivaba salvestuste vaatamine, ning vanade salvestuste kätte saamine kui tulevikus echo360 tarkvara uueneb. Salvestused on kategoriseeritud kooli ja aine alusel. Salvestuste vaatamiseks pole vaja kasutajat, kuigi redigeerimiseks/lisamiseks on vaja.
+====Must have====
+* Video konverteerimine
+* Kategoriseerimine EIK ainete alusel
+* Video striimimine meie veebiliides
+* Videode lisamine / eemaldamine
+* Logi kirjete kogumine
+* mp4 exportimine
+====Nice to have====
+* Timestamp ja nende avalik kommenteerimine salvestusele
+* Konveteerimise progress
+* Kategoriseerimine Kooli ja aine alusel
+* Kooli kasutajaga sisselogimine
+* Videote otsing aine/õppejõu alusel
