Comment (by sysrqb):

 Okay, on older Android versions (Jellybean and earlier) Fennec uses a
 custom async wrapper around Android built-in MediaCodec system for
 handling media files/streams. On newer versions, Android provides an async
 MediaCodec library, and Fennec uses that directly. Therefore, it seems
 like this should work on all supported versions, but the error log above
 indicates this isn't the reality:
 {{{
 E/MediaCodec( 2336): Codec reported an error. (omx error 0x80001001,
 internalError -2147483648)
 W/System.err( 2336): java.lang.IllegalStateException
 W/System.err( 2336): java.lang.IllegalStateException
 W/System.err( 2336):    at
 android.media.MediaCodec.dequeueInputBuffer(Native Method)
 W/System.err( 2336):    at
 org.mozilla.gecko.media.JellyBeanAsyncCodec$BufferPoller.pollInputBuffer(JellyBeanAsyncCodec.java:216)
 }}}

 I'll dig into this a little more (and GeKo suggested testing a vanilla
 Fennec build, so I'll try that, too).
