gstreamer-vaapi MJPEG streaming

[lopezavila69]

Hello,

I would need to know the correct pipeline to decode MJPEG streaming with gstreamer-vaapi. I don't know even if it is possible in this case.

I am working with "special" PowerVR SGX 545 GPU and I load the "pvr" driver in xorg.conf. I would like to connect to an IP device which sends MJPEG streaming, so I am using souphttpsrc as the first element in the pipeline.

For instance, if I use the following pipeline:
gst-launch -v souphttpsrc location='http://a.b.c.d/' ! valve ! jpegdec ! ffmpegcolorspace ! vaapiupload ! vaapisink

Streaming ends with the following errors:

[0x05b0abe2]psb_drv_video error(6812:0xb76fb6c0) target VAImage fourcc should be NV12 or IYUV

[...] And the streaming freezes after a pair of seconds:

[0x05b0b4ad]psb_drv_video error(6812:0xb64ffb40) psb_putsurface_textureblit: Failed to get source PVR2DMEMINFO!
Caught SIGSEGV accessing address 0x10
#0  0xb77e9424 in __kernel_vsyscall ()
#1  0x43e54c50 in ?? ()
Spinning.  Please run 'gdb gst-launch 6812' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

I am working with gstreamer-0.10.36 and gstreamer-vaapi-0.5.2.

Any help is appreciated.
