Composite video to .264 using gstreamer issue
 
|
Hi, My requirement currently is to get continuous frames from a composite input and dump it into a .264 file using the gstreamer. I kept the gst-launch script to a minimum and ran it (see below) and the output was an error.
root@dm365-evm:/home# gst-launch -v v4l2src always-copy=FALSE num-buffers=800 in put-src=composite ! video/x-raw-yuv, format= (fourcc)NV12, width=720, height=480 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=/home/ gr8.264 -sh: syntax error: "(" unexpected
After a few trials I removed the (fourcc) and tried again. This is what I got (below)
root@dm365-evm:/home# gst-launch -v v4l2src always-copy=FALSE num-buffers=800 in put-src=composite ! video/x-raw-yuv,format=NV12,width=720,height=480 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=/home/gr8.264 WARNING: erroneous pipeline: could not link v4l2src0 to tividenc10
I believe this is preliminary stuff, but I am following one off examples from the ti wiki for gstreamer. Any help!

Please try escaping the parentheses characters. \(fourcc\)NV12 2012/8/20 kartik natarajan <[hidden email]>: > > > > Hi, > > My requirement currently is to get continuous frames from a composite > input and dump it into a .264 file using the gstreamer.

David, Thanks a ton for your precise and prompt reply. Use of the ' ' makes the script work and I have just hit another roadblock. The input I want is the composite in from a camera, but here the input defaults to the highlight, a series of capture events follow to end in a segmentation fault. [SEE BELOW]
Please advice. N.Kartik root@dm365-evm:~# gst-launch -v 'v4l2src always-copy=FALSE mum-buffers=800 input -src=composite ! video/x-raw-yuv, format=(fourcc)NV12, width=720, height=480 !

Ok, so now I have tried using the \(fourcc\)NV12, as Ruben suggested and without the single quotes.
I found more stuff happening on the console. The gr8.264 file got created as well but it seems corrupted. Somehow my camera is not being read is what I feel. Could you please help me with this. Here is the console snapshot

Thanks Guys for you help.
I just had to change the resolution. All works fine now with 640x480 and even 736x480 resolution Regards, N.Kartik Senior Developer | Renu Electronics Pvt. Ltd.
