Follow Up

Please try latest svn version r153 i have added an experimental support for MJPEG ( Motion Jpeg ).

Let me know any issue to improve the support to V4L2_PIX_FMT_MJPEG.

Ok seems that motion jpeg needs a Huffman table , because the jpeg data is not complete in a jpeg frame. Let me figure out how to add it to allow jpeg decode properly the jpeg frame.

Answer

I've added an experimental support for MJPEG ( V4L2_PIX_FMT_MJPEG ) in current svn version ( r159 ).

Please test it, open any bug related to problem with it.
