<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I have been using the omx264dec to decode a stream coming from a camera, the Logitech C920 which provides an h264 stream, in a Raspberry PI.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">When I try to decode this stream with omx264dec the video is mostly corrupted getting a bit better if there is motion in the video.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">According to my tests the omx264dec works correctly with Apple's h264 sample file and it also works well decoding video encoded by omxh264enc but not video encoded by x264enc.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">On the other hand I have tried decoding the stream of C920 with avdec_h264 and the output is not corrupted at all, leading me to believe in a omx decode bug or incompatibility.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">This problems are reproducible with gstreamer version of raspbian.
<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Can anybody suggest a solution or should I file a bug?<o:p></o:p></p>
</div>
<p class="MsoNormal">Thank you<o:p></o:p></p>
