TI Gstreamer Demo Problem

Other Parts Discussed in Thread: TVP7002

Hi,

I am using the DVSDK_DM368_EVM_4_01_00_09 for my DM368 board. Since I am new to all this, I followed the DM368 Developers Guide to get everything set up.  I tried out all the example commands. I was able to encode/decode video files and images, but I was having problems with all the gstreamer examples.  I have tried google the error messages, but I was unable to find any solutions. Any help from you guys here are much appreciated! 

 

Command: To decode 1000 frames of AAC audio to headphone output execute:

# ./audio_decode1_dm368.x470MV -c aac_dec  -n 1000 -i /usr/share/ti/data/sounds/davincieffect.aac

Output:
 Sample rate 44100 detected
################################Failed to write audio buffer
End of application.

 

Command: This pipeline decodes MPEG-4 video decode to 720P component output:

    shake hands, I got a lot of trouble using gstreamer on DM368 board too.

    What's working on my DM368EVM running DVSDK4.02:

    gst-launch videotestsrc  peer-alloc=false ! TIDmaiVideoSink useUserptrBufs=true numBufs=3 videoStd=720P_60 videoOutput=component

    gst-launch filesrc location=/usr/share/ti/data/videos/davincieffect.mpeg4 ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! queue max-size-buffers=2 max-size-time=0 max-size-bytes=0 ! TIDmaiVideoSink videoStd=720P_60 videoOutput=component sync=false hideOSD=true numBufs=3 useUserptrBufs=TRUE

    What's not working:

    gst-launch v4l2src always-copy=false num-buffers=1 ! video/x-raw-yuv,width=640,height=480 ! filesink location=test.raw

    Stuck at: New clock: GstSystemClock

    Hello,

    Please note the current v4l2src does not support capturing from camera, whereas it has been patched to work with component and composite input. So you are trying  to use camera then you may need to patch it a bit further. And if you are using composite or component input then make sure your bootargs are set right.

    Thanks

    Brijesh:

    Can you point me to the source files I should look into?

    Thanks.

    I have exactly the same problem as HongFeng had with DM368. I have a DM365 EVM. I was able to run the encode/decode demo to 720P camera input to a file and play it back. I was also able to play the recorded file using gstreamer. But when I tried:

    gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input-src=component ! 'video/x-raw-yuv,format=(fourcc)NV12,widt                                                                                        
    h=1280,height=720' ! filesink location=xxx      

    I got the following output:

    But the file "xxx" has 0 bytes. Does this mean I'll need to extend v4l2src to be able to capture camera inputs, is there any alternatives I can try?
