Corrupt JPEG data: premature end of data segment [GSPCA v2]
Question
Hi. I'm trying to use a USB WebCam using GSPCA v2 (with V4L2) but I'm getting [1] Corrupt JPEG data: premature end of data segment. The camera is working only on Ekiga with no problem using V4L2. I tried before with a GSPCA V1 (with V4L1) and It worked in Motion but I was getting a black dotted bar in the bottom of the stream. (I was getting that bar also on other software). So for that reason I decided to try the new driver.[0] Processing thread 0 - config file motion.conf [0] Motion 3.2.9 Started [0] ffmpeg LIBAVCODEC_BUILD 3352064 LIBAVFORMAT_BUILD 3344896 [0] Thread 1 is from motion.conf [1] Thread 1 started [1] cap.driver: "zc3xx" [1] cap.card: "USB Camera (046d:089d)" [1] cap.bus_info: "usb-0000:02:0a.1-2" [1] cap.capabilities=0x05000001 [1] - VIDEO_CAPTURE [1] - READWRITE [1] - STREAMING [1] Supported palettes: [1] 0: JPEG (JPEG) [1] Test palette JPEG (320x240) [1] Using palette JPEG (320x240) bytesperlines 320 sizeimage 29390 colorspace 00000007 [1] found control 0x00980900, "Brightness", range 0,255 [1] "Brightness", default 128, current 127 [1] found control 0x00980901, "Contrast", range 0,256 [1] "Contrast", default 128, current 128 [1] found control 0x00980910, "Gamma", range 1,6 [1] "Gamma", default 4, current 3 [1] found control 0x00980912, "Auto Gain", range 0,1 [1] "Auto Gain", default 1, current 1 [1] mmap information: [1] frames=4 [1] 0 length=32768 [1] 1 length=32768 [1] 2 length=32768 [1] 3 length=32768 [0] motion-httpd/3.2.9 running, accepting connections [0] motion-httpd: waiting for data on port TCP 8001 [1] Using V4L2 [1] Error capturing first image [1] Thread finishing... egorian@ubuntuServer:~$ sudo motion -d20 -c motion.conf [0] Processing thread 0 - config file motion.conf [0] Motion 3.2.9 Started [0] ffmpeg LIBAVCODEC_BUILD 3352064 LIBAVFORMAT_BUILD 3344896 [0] Thread 1 is from motion.conf [1] Thread 1 started [1] cap.driver: "zc3xx" [1] cap.card: "USB Camera (046d:089d)" [1] cap.bus_info: "usb-0000:02:0a.1-2" [1] cap.capabilities=0x05000001 [1] - VIDEO_CAPTURE [1] - READWRITE [1] - STREAMING [1] v4l2_select_input: name = "zc3xx", type 0x00000002, status 00000000 [1] - CAMERA [1] Device doesn't support VIDIOC_G_STD [1] Supported palettes: [1] 0: JPEG (JPEG) [1] Test palette JPEG (320x240) [1] Using palette JPEG (320x240) bytesperlines 320 sizeimage 29390 colorspace 00000007 [1] found control 0x00980900, "Brightness", range 0,255 [1] "Brightness", default 128, current 127 [1] found control 0x00980901, "Contrast", range 0,256 [1] "Contrast", default 128, current 128 [1] found control 0x00980910, "Gamma", range 1,6 [1] "Gamma", default 4, current 3 [1] found control 0x00980912, "Auto Gain", range 0,1 [1] "Auto Gain", default 1, current 1 [1] mmap information: [1] frames=4 [1] 0 length=32768 [1] 1 length=32768 [1] 2 length=32768 [1] 3 length=32768 [0] motion-httpd/3.2.9 running, accepting connections [0] motion-httpd: waiting for data on port TCP 8001 [1] Using V4L2 [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] processing jpeg image - content length 2044 [1] Corrupt JPEG data: premature end of data segment [1] Error capturing first image [1] Thread finishing...

Answer
You can try to ignore warning of jpeg : if (ret == 1) {
if (debug_level >= CAMERA_WARNINGS)
motion_log(LOG_ERR, 0, "%s: Corrupt image ... continue", __FUNCTION__);
ret = 2;
} Replacing ret = 2 to ret = 0 : And build again motion ( make ; sudo make install ) -- AngelCarpintero - 04 Sep 2009 Thanks for your help Angel. I forced to ignore the jpeg warning and I got an image from Motion. But I'm still getting an image with a bar at the bottom as using V4L1. I posted an image example (http://img245.imageshack.us/i/screenshotwebcam.jpg/) at the bottom of the image there is a gray bar. Do you think this is a problem with a buggy driver? -- EstuardoGorian - 04 Sep 2009sed -ie 's/ret = 2/ret = 0/g' video_common.c
Yah , looks like the issue is in the driver, JPEG works good with uvcvideo driver. -- AngelCarpintero - 04 Sep 2009
