The first bug of RTSP streaming feature on B2G is bug 831645, which implemented most of the framework of our RTSP. <br>
{{Bug|831645}} - Support rtsp streaming framework <br>
{{Bug|831645}} - Support rtsp streaming framework <br>
This is the first bug of RTSP streaming feature on B2G, which implemented most of the RTSP framework in Firefox OS. <br>
{{Bug|992568}} - [RTSP] Refactor RtspChannel to support HTTP->RTSP redirection and rendering inside the browser
Although the basic framework was ready, before FFOS v1.4, RTSP on B2G is render in the video app and supports only <a> and <video> tags. <br>
We had made a decision (in https://bugzilla.mozilla.org/show_bug.cgi?id=963565#c13) to render RTSP directly inside the B2G browser app. <br>
This bug serves as the collective implementation of several features, including:
* Support RTSP in URL bar and <iframe>.
* Support HTTP->RTSP redirection.
* Render RTSP inside the browser.


In B2G v2.0, we had a huge progress in improvements of RTSP. The meta bug of RTSP in v2.0 is bug 957937. <br>
{{Bug|957937}} - (b2g-RTSP-2.0) [META] RTSP for 2.0 <br>
{{Bug|957937}} - (b2g-RTSP-2.0) [META] RTSP for 2.0 <br>
This is the meta bug of RTSP features in v2.0. We made a huge improvement in quality and reliability of RTSP feature in this version. <br>
