gstreamer plugin VPU_DecOpen() fails

alexandershashk — Wed, 14 May 2014 15:29:21 GMT

Hello all,

I'm using gstreamer to play mpeg2 stream from udp, but my vpudec plugin fails to initialize. Here is my pipeline:

gst-launch udpsrc uri=udp://0.0.0.0:1234 ! mpegtsdemux ! queue ! mpegvideoparse ! vpudec ! ximagesink

The error log is following:

0:00:00.736662000 23721 0x4330ec60 INFO     vpudec vpudec.c:1185:gst_vpudec_setcaps: Get upstream caps video/mpeg, mpegversion=(int)2, systemstream=(boolean)false, parsed=(boolean)true, width=(int)720, height=(int)480, framerate=(fraction)60000/1001, pixel-aspect-ratio=(fraction)8/9, codec_data=(buffer)2d01e024249f23821020202620262c2c2c2c2c2c343034363636343434343636363a3a3a4444443a3a3a36363a3a404044444a4c4a464644464c4c50505060605c5c7070748a8aa710111112121213131313141414141415151515151516161616161616171717171717171718181819181818191a1a1a1a191b1b1b1b1b1c1c1c1c1e1e1e1f1f21000001b5148200010000000001b8, profile=(string)main, level=(string)low, interlaced=(boolean)true

For me line "Get codec std 10" looks strange. Why codec 10? From docs I found following typedef used for decoder initialization:

typedef enum {
STD_MPEG4 = 0,
STD_H263 = 1,
STD_AVC = 2,
STD_VC1 = 3,
STD_MPEG2 = 4,
STD_DIV3 = 5,
STD_RV = 6,
STD_MJPG = 7,
STD_AVS = 8,
STD_VP8 = 9,
} CodStd;

And there is no codec with id 10. MPEG2 has id 4. What's wrong or missing?

Here is version of plugin:

vpudec versions :

plugin: 3.0.7

wrapper: 1.0.35(VPUWRAPPER_ARM_LINUX Build on Jul 2 2013 08:38:58)

vpulib: 5.4.12

firmware: 2.1.9.36350

Thank you in advance!

did you use mx6q? could you give me reproduced steps, let me tested it on my board.

The question is old and discussion can be closed. I figured out that board's manufacturer had provided kernel with incorrect settings, that was a cause for this error. I replaced kernel with newer version and problem is gone.
