DM-365, GStreamer pipeline

Jiri Brabec

Hi,

I try to use GStreamer on DM-365, TI DVSDK 4.0.0.22, but without success. I want to encode a video from a composite source to some file, so I run the following pipeline (that I got from TI sites with examples of pipelines), but I did not get any output and the following warning occured:

gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input-src=composite !
'video/x-raw-yuv,format=(fourcc)NV12,width=720,height=480' !
'TIVidenc1 codecName=mpeg4enc engineName=codecServer' !
'filesink location=output_cap_D1.m4v'

WARNING: erroneous pipeline: could not link v4l2src0 to tividenc10

Thank you

Jiri,

Have you tried runing the pipeline documented in Software Developers Guide ?

Thanks

Brijesh,
thanks for your help.
I run GStreamer on the DM-365 processor from Texas Instruments, and I test pipelines that TI gives as examples on http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines site.

Hi, Jiri!

I also work with composite input. I have a PAL camera.

First check bootargs.

For example, there should be the following options:

davinci_enc_mngr.ch0_output=COMPOSITE

davinci_enc_mngr.ch0_mode=PAL

Next, you can try the following example:

gst-launch -v v4l2src always-copy=FALSE input-src=composite ! 'video/x-raw-yuv,format=(fourcc)NV12,width=640,height=480' ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=test.264

it works! (640x480)

Video can be recorded into the mkv-container.

It also works.

In my case, h264enc works with 320x240, 640x480, but there are problems with other video resolution.

The Software Developers Guide does not contain GStreamer examples for use with D1 (720p only!)

Hi, now it works fine, problem was the video resolution. Thanks for your help, Jiri

Hi, Senchuss

My case is just like you described, I can only get correct picture with the resolution you mentioned. Have you solved this problem? My board is DM368 EVM, dvsdk4.02

Hi,

I have never tried with D1 format, but I succeeded in 720p or 1080i formats.

Here are some things which can make your pipeline not working:
- Have you tried your pipeline with framerate information (for instance : framerate=(fraction)25/1 - or 30/1, if NTSC -) ?
- Also check your bootargs, you must mention what input source you want to use...

Could you tell us what is the error you get, via the log?

Hi, Julien

Thanks for reply.

There were no error, but the video is not correct, just like playing an wrong resolution video.
