[Live-devel] Incomplete decoded image data

[Guy.Bonneau at miranda.com]

This is a guessing but by digging in the encoded parameters you'll probably
be able to confirm this hypothesis.

If the "display" picture is really 800x600 as provided by the attached png
file then the stream parameter might specify a 800x600 video display. Yet
the camera might encode only the 592 lines since 600 is not a multiple of
16 lines. The last 8 lines from the FFMPEG (VLC) decoder seems shifted and
might be an artefact of the internal buffer decoding. However the Cuda
decoder might "realize" that the encoded video is only 592 lines and might
replace the  last missing 8 lines with black data.

Note that this doesn't explain why the last valid macroblock of Cuda seems
to be corrupted.

Use Elecard StreamEye Analyzer ! it will probably help by giving you more
hints.

If the only difference between your two systems is the decoder that you
use, then that's a rather strange conclusion to draw.
