Writing raw frames to mpegts [SEC=UNCLASSIFIED]

Durrand, Paul (Contractor)

UNCLASSIFIED

Hi,
 
I am currently trying to develop an application which utilises GStreamer to write and YUV format mpegts file. The driver uses appsrc to write raw RGB frames to a YUV mpegts file.
 
I am trying to get a pipeline together and as I'm new to GStreamer I am not quite sure which plugins and caps to set.I was hoping someone can point me in the right direction.
 
With the pipeline: "appsrc name=\"adsssrc\" caps=\"video/x-raw-rgb,width=704,height=480,framerate=(fraction)25/1\" ! ffmpegcolorspace ! video/x-raw-yuv ! ffenc_mpeg2video ! mpegtsmux ! filesink location=processed.mpg " I get the following errors:

RE: Writing raw frames to mpegts [SEC=UNCLASSIFIED]

Durrand, Paul (Contractor)

UNCLASSIFIED

I am making slight progress with this problem. I have fully defined the caps for APPSRC to match those specified as a SINK in ffmpegcolorspace. My new pipeline is (the rest of the source is below in the original email):
 
  char *fullPipelineDesc = "appsrc is-live=true name=\"adsssrc\" caps=\"video/x-raw-rgb,width=704,height=480,framerate=(fraction)25/1,bpp=24,depth=24,red_mask=255,green_mask=65280,blue_mask=16711680,endianness=4321\" ! ffmpegcolorspace ! video/x-raw-yuv,width=704,height=480,framerate=(fraction)25/1,format=(fourcc)I420 ! ffenc_mpeg2video ! mpegtsmux ! filesink location=processed.mpg ";
 
With this I see the following error:
 
  basetransform gstbasetransform.c:1047:gst_base_transform_acceptcaps:<capsfilter0>ESC[00m transform could not transform video/x-raw-rgb, width=(int)704, height=(int)480, framerate=(fraction)25/1, bpp=(int)24, depth=(int)24, red_mask=(int)255, green_mask=(int)65280, blue_mask=(int)16711680, endianness=(int)4321 in anything we support
This puzzles me as the both the sink and src capabilities match the output I see from "gst-inspect-0.10 ffmpegcolorspace". Am I missing something?
 
Thanks,
Paul

RE: Writing raw frames to mpegts [SEC=UNCLASSIFIED]

Durrand, Paul (Contractor)

UNCLASSIFIED

I resolved my issue by removing the caps filter after the ffmpegcolorspace. I also added in videorate and I generate an mpegts.
 
The new pipeline is:
 
char *fullPipelineDesc = "appsrc is-live=true name=\"adsssrc\" caps=\"video/x-raw-rgb,width=704,height=480,framerate=(fraction)25/1,bpp=24,depth=24,red_mask=255,green_mask=65280,blue_mask=16711680,endianness=4321\" ! ffmpegcolorspace ! videorate ! ffenc_mpeg2video ! ffmux_mpegts ! filesink location=processed.mpg ";
