<span class="application">MEncoder</span> supports encoding to Sony PSP's video
format, but, depending on the revision of the PSP software, the constraints
may differ.
You should be safe if you respect the following constraints:
</p><div class="itemizedlist"><ul type="disc"><li><p>
<span class="bold"><strong>Bitrate</strong></span>: it should not exceed 1500kbps,
however, past versions supported pretty much any bitrate as long as the
header claimed it was not too high.
</p></li><li><p>
<span class="bold"><strong>Dimensions</strong></span>: the width and height of the
PSP video should be multiples of 16, and the product width * height must
be <= 64000.
Under some circumstances, it may be possible for the PSP to play higher
resolutions.
</p></li><li><p>
<span class="bold"><strong>Audio</strong></span>: its samplerate should be 24kHz
for MPEG-4 videos, and 48kHz for H.264.
</p></li></ul></div><p>
