LVDS and CODEC Sync

[akashchandra]

Hi,

I am working on a board which is having two LVDS displays and two Audio codecs. I am porting MORTY SDK on it. Gstreamer1.0 package is available in MORTY. I am able to play audio on both the codecs but I am unable to play video on both the displays. Also I am unable to play audio and video simultaneously. Can anyone tell me gst-launch-1.0 pipeline description so that I can sync audio and video at same time?

Thanks.

Hi Igor,

Thanks for your response. According to Linux Guide section7.3.1.3 we should know audio-video decoder and sink plugins. I am unable to find those plugins. I used gst-inspect-1.0 command to find the plugins and tried the following command:

 gst-launch-1.0 filesrc location=/media/Coldplay.mp4 typefind=true ! imxvpudec ! imxipuvideosink &

But it showed the following errors:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstImxVpuDecoder:imxvpudecoder0: VPU decoder was not created
Additional debug info:
../src/vpu/decoder.c(466): gst_imx_vpu_decoder_handle_frame (): /GstPipeline:pipeline0/GstImxVpuDecoder:imxvpudecoder0
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

Do you know how to find the required plugins?

Thanks.
