<p>This document describes the media codec, container, and network protocol support provided by the Android platform.</p>

<p>As an application developer, you are free to make use of any media codec that is available on any Android-powered device, including those provided by the Android platform and those that are device-specific. <strong>However, it is a best practice to use media encoding profiles that are device-agnostic</strong>.</p>


<h2 id="network">Network Protocols</h2>

<p>The following network protocols are supported for audio and video playback:</p>

<ul>
  <li>RTSP (RTP, SDP)</li>
  <li>HTTP/HTTPS progressive streaming</li>
  <li>HTTP/HTTPS live streaming <a href="http://tools.ietf.org/html/draft-pantos-http-live-streaming">draft protocol</a>: <ul>
    <li>MPEG-2 TS media files only</li>
    <li>Protocol version 3 (Android 4.0 and above)</li>
    <li>Protocol version 2 (Android 3.x)</li>
    <li>Not supported before Android 3.0</li>
  </ul></li>
</ul>

<p class="note"><strong>Note:</strong> HTTPS is not supported before Android 3.1.</p>


<h2 id="core">Core Media Formats</h2>

<p>The table below describes the media format support built into the Android platform. Note that any given mobile device may provide support for additional formats or file types not listed in the table.</p>

<p class="note"><strong>Note:</strong> Media codecs that are not guaranteed to be available on all Android platform versions are accordingly noted in parentheses&mdash;for example &quot;(Android 3.0+)&quot;.</p>

<h2 id="recommendations">Video Encoding Recommendations</h2>

<p>Table 2, below, lists examples of video encoding profiles and parameters that the Android
media framework supports for playback in the H.264 Baseline Profile codec. While
table 3 lists examples that the framework supports for playback in the VP8 media codec.</p>

<p>In addition to these encoding parameter recommendations,
a device's available <em>video recording</em> profiles can be used as a proxy for media playback
capabilities. These profiles can be inspected using the {@link android.media.CamcorderProfile
CamcorderProfile} class, which is available since API level 8.</p>

<p style="margin-top: 2em">For video content that is streamed over HTTP or RTSP, there are additional requirements:</p>

<ul>
  <li>For 3GPP and MPEG-4 containers, the <code>moov</code> atom must precede any <code>mdat</code> atoms, but must succeed the
      <code>ftyp</code> atom.</li>
  <li>For 3GPP, MPEG-4, and WebM containers, audio and video samples corresponding to the same time offset may be no more than 500 KB apart.
      To minimize this audio/video drift, consider interleaving audio and video in smaller chunk sizes.</li>
