[maemo-users] gst-launch and openmax

[From: Aldon Hynes]

I deliberated whether this was a developer or a user type question.  Since
it was about using existing programs, as is, I opted for user....

Anyway...

When I tried omx_jpegenc I got

WARNING: erroneous pipeline: no element "omx_jpegenc"

When I tried jpegenc I got

WARNING: erroneous pipeline: could not link v4l2camsrc0 to jpegenc0

When I tried pngenc I got

WARNING: erroneous pipeline: could not link v4l2camsrc0 to pngenc0

When I tried dspjpegenc, it captured a picture, but my image was all black.

Sounds a bit like a developer topic.  :) Anyway, that's just the hardware
accelerated jpeg encoder, it's not essential (you can use any other image
format). There have been some gstreamer element shufflings with PR1.1, try
dspjpegenc or simply jpegenc. If you want to get extreme, you could even use
pngenc for lossless imagery :)
