Questions about iMx61solo in MJPEG encoding mode

We'd like to use iMX61Solo as the video processing processor for one of our projects, which presents the following requirements:

1. MJPEG encoding;

2. input image size: 12Mpixes;

3. encoded frame rate: >=13fps;

4. compression ratio: >=20:1


From the data sheet of iMX61Solo, there will be no problems for the first three requirements,

since MX61Solo supports MJPEG encoding BP standard.

But how about the last one? Since MJPEG encoding  is an intraframe compression,

probably the compression ratio depends on the input image heavily.  Right?


Is there any lower or upper limits on the compression ratio of iMX61Solo in MJPEG encoding mode?


And how about the bitrate?  Giving the input image size is 12Mpixel and 2Bytes/pixel (I420), 13fps.

Has the gstreamer  multimedia framework been ready for supporting iMX61Solo?


Best regards,
