convert wmv to ogv

[Jerry Geis]

I am trying this pipeline to convert wmv to ogv.

gst-launch filesrc location=../trailer_videos/Amazon_1080.wmv !

                decodebin ! name=demux ! queue ! ffmpegcolorspace ! theoraenc ! 

                oggmux name=mux ! filesink location=../Amazon.ogv  demux. ! queue ! progressreport !

                audioconvert ! audioresample ! vorbisenc ! mux.

and getting this error:

0:00:00.025897773 25225      0x107d200 ERROR           GST_PIPELINE ./grammar.y:735:priv_gst_parse_yyparse: link without source element

WARNING: erroneous pipeline: link without source element

I'm stuck... What do I have wrong.

Thanks,

jerry

If you are trying to name the decodebin "demux", remove the "!" in
"...decodebin ! name=demux..." ?

Just thoughts on how to proceed, I don't have a ready answer. I rarely use decodebin, but it looks like it is trying to find a decoder for video cap video/x-fluendo-va, that it can't load for some reason, or doesn't exist on your system.

Try using GST_DEBUG=<blah>:<x> (see http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gst-running.html) in front of gst-launch to watch the file format discovery and caps negotiation. Be prepared for an avalanche of output.

Also to see what you have installed that handles video/x-fluendo-va, try:

$ gst-inspect -a | grep x-fluendo-va

Perhaps that file can be decoded with filesrc ! avidemux ! ffdec_wmv<n> ?

Last, obligatory suggestion to use gstreamer 1.x if you can (gst-launch-1.0; gst-launch on your system might link to gstreamer 0.10 stuff).

Cheers,

Mark.

Ok so I dropped decodebin and added fluwmvdec, I get a new error.

Not sure how more straightforward this error could be. But let me
explain. You have asked AVI demuxer to demux an ASF (often show as
.wmv). In the previous pipeline, you are asking a fluwmbdec to decoded
something that have not yet been demuxed.

Hi Nicolas,

Thanks for responding... I only tried the avidemux as it was suggested in the previous post.

I do realize the difference between AVI and wmv. :)

However, I wish to use the fluwmvdec and decode/convert this file. I am trying to learn how all this pipe stuff works,

thought I had a good example that I found, tried it and its not working. 

Would greatly appreciated the correct pipeline to convert the wmv to ogv.

Thanks,

Jerry

I'm not sure why you wanted to do this manually, but anyway. Here's a
pipeline that fits the media you have chosen. I have no idea about
fluvmcdec, so I have used avdec_wmv3, you may try and replace it.

gst-launch-1.0  \
  filesrc location=Amazon_1080.wmv ! asfdemux name=demux \
  demux. ! queue ! avdec_wmv3 ! theoraenc ! mux. \
  demux. ! queue ! avdec_wmapro ! vorbisenc ! mux. \
  oggmux name=mux ! filesink location=test.ogg

Obviously you will have to rewrite this pipeline for each media. A more
generic pipeline would be:

gst-launch-1.0  \
  filesrc location=Amazon_1080.wmv ! decodebin name=dec \
  dec. ! video/x-raw ! queue ! theoraenc ! mux. \
  dec. ! audio/x-raw ! queue ! vorbisenc ! mux. \
  oggmux name=mux ! filesink location=test.ogg

If fluwmvdec is a fit for the task and is ranked high enough, decodebin
bin will pick it automatically. All you have to care is to make sure it
is installed.

Hi Nicolas

I see the difference in your command - thanks - however. I still get an error. (see below)

I tried this with both 0.10 and 1.0 and got the same error.

gst-launch filesrc location=../trailer_videos/Amazon_1080.wmv '!' decodebin name=dec dec. '!' video/x-raw '!' queue '!' theoraenc '!' mux. dec. '!' audio/x-raw '!' queue '!' vorbisenc '!' mux. oggmux name=mux '!' filesink location=../test.ogg

Setting pipeline to PAUSED ...

Pipeline is PREROLLING ...

Missing element: video/x-fluendo-va decoder

Thougths?

Hi Jerry,

For support with Fluendo's elements you should probably contact Fluendo.

I would recommend you remove all the Fluendo plugins, you can achieve
the same thing using open source components, namely using asfdemux from
gst-plugins-ugly and ffdec_* (avdec_* in 1.0) from gst-ffmpeg (gst-libav
in 1.0).

Perhaps try the explicit non-decodebin pipeline Nicolas gave you.

FWIW your original pipeline above worked fine for me with gstreamer
0.10, and with slight mods (videoconvert instead of ffmpegcolorspace)
also in gstreamer-1.0, using packages provided by Ubuntu Trusty. So I
suspect there's something going on with your particular install and
collection of elements.

I tested with a source wmv file by the same name that I found online,
with md5sum e326c01834fd88a71763d6a961b9237c.

Cheers,

Mark.
