Sebastien, we use other conventions. In this case, the bug is reproduceable w/o
ffmpegcolorspace. Convert the image to PNG using GIMP and run:

gst-launch filesrc blocksize=9999999 location=in.png ! pngdec ! ffmpegcolorspace
! jpegenc ! filesink location=out.jpg
gst-launch filesrc blocksize=9999999 location=in.png ! pngdec ! pngenc !
filesink location=out.png
gst-launch filesrc blocksize=9999999 location=in.png ! pngdec ! ffmpegcolorspace
! video/x-raw-yuv ! ffmpegcolorspace ! pngenc ! filesink location=out.png

All are fine. Now run:

gst-launch filesrc blocksize=9999999 location=in.jpg ! jpegdec ! jpegenc !
filesink location=out.jpg
gst-launch filesrc blocksize=9999999 location=in.jpg ! jpegdec !
ffmpegcolorspace ! video/x-raw-rgb,bpp=32,depth=32 ! ffmpegcolorspace ! jpegenc
! filesink location=out.jpg
gst-launch filesrc blocksize=9999999 location=in.jpg ! jpegdec !
ffmpegcolorspace ! pngenc ! filesink location=out.png

All have random data as first few bytes for each line except the first per
block. This automatically implies that the bug is in jpegdec and that
ffmpegcolorspace is bugfree.
