Description tsing 2009-02-19 13:58:18 UTC 
when I tpyed this command:
 gst-launch filesrc location=111.jpg ! jpegdec ! filesink location=222
 gst-launch filesrc location=222 ! jpegdenc ! filesink location=111bak.jpg

I think with these commands,I can convert the jpeg file into YUV bitstream,and recover the YUV bitstream to the jpeg. but the error occur when I run with:
gst-launch filesrc location=222 ! jpegdenc ! filesink location=111bak.jpg

the reslut is segment default.Is there any error in my command ,or it is the bugs with the Gstreamer plugins ?

Both. GStreamer crashing is always a bug. It should error out correctly in this case.

However, your pipeline is also wrong. You will need to use a rawvideoparse element if you want to read raw YUV frames from a file (make sure to set the right properties, format/width/height etc.).

    jpegenc: error out instead of crashing if no caps have been set
    
    Don't crash if we receive a buffer without caps. Fixes #572413.
