jpegenc_sn.dll64P that works?

[Jeff Mills]

I've been trying to get the dspjpegencoder to work for the last couple days or so on my beagleboard-XM. I want to use it to encode mjpeg from my webcam. I know the one in  L23.i3.8 doesn't work, so I tried to get the one from L23.i3.3, but I get an "algo error"

The binaries I've been using are from http://gst-dsp.googlecode.com/files/tidsp-binaries-23.i3.8.tar.gz (which I thought had a working jpegencoder). 

This line works great without dsp: 

gst-launch videotestsrc num_buffers=200 ! jpegenc ! fakesink -v

With dsp binaries from tidsp-binaries-23.i3.8.tar.gz: 

gst-launch videotestsrc num_buffers=200 ! dspjpegenc ! fakesink -v

dspmp4venc and dsph263enc work fine so I know DSP is working. I've tried compiling gst-dsp with both SN_API=1 and SN_API=2, still not works.

Is there anyway to get mjpeg encoding on the beagleboard's DSP with ubuntu?

The README explains it:

Note that the jpeg encoder in L23.i3.8 doesn't work (they compiled it wrongly),
and the one in L23.i3.3 might hang on some pipelines; you might have to turn
off enable-last-buffer, since only one output buffer would be available at any
given time.

Have you tried that property in the video sink you are using?
