sample video file encoding in gstreamer

[mfsakht]

I can encode and decode a test video with following pipelines:

gst-launch-0.10 -v videotestsrc num-buffers=2000 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=sample.264

gst-launch-0.10 -v filesrc location=sample.264 ! TIViddec2 codecName=h264dec engineName=codecServer ! filesink location=sample.raw

but I can’t encode a sample raw video file like sample.raw with following pipelines:

gst-launch-0.10 -v filesrc location=sample.raw num-buffers=2000 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=sample.264

ERROR: failed to create video encoder h264enc

gst-launch-0.10 -v filesrc location=sample.raw num-buffers=2000 ! video/x-raw-yuv,width=320,height=240,framerate=30 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=sample.264

ERROR: could not link filesrc0 to tividenc10

The caps are incomplete in the second example (at least the format is
missing), and in the first you don't provide any at all. But even if
you provide complete caps, you need something that reads exactly one
raw video frame per buffer. filesrc can't do that, see the videparse
element.

You should also consider updating to GStreamer 1.x. The 0.10 version is
no longer maintained since more than 3 years and you're unlikely to get
any support for it anymore.
