HTTP video source serves individual JPEG images

Guillermo Rodriguez Garcia
Hello all,

I am trying to use gstreamer to stream video (sort of) from a HTTP source
that serves individual JPEG images. This is not a MJPEG stream -- instead,
a new HTTP request is required for each frame that is to be retrieved.

This pipeline works for MJPEG:

gst-launch souphttpsrc location=http://user:pass@hostname/path ! jpegdec ! xvimagesink

If I try to use the same pipeline for an HTTP source that serves individual
JPEG images, only one image is shown (since the HTTP response actually
contains just one single image).

Is there any way to have souphttpsrc make additional requests periodically
from the specified location?

Is there any other way to achieve this?

Thanks,

GRodriguez

gst-launch souphttpsrc location=http://user:pass@hostname/path ! multipartdemux

Thanks for your answer. This pipeline does work for MJPEG (just like
the one I provided above), but does not solve the problem.

I don't have an MJPEG stream. What I have is a HTTP source that serves
individual JPEG images (one single JPEG image per HTTP request). What
I actually need is a way to have souphttpsrc (or another HTTP src) make
additional HTTP requests periodically from the same URL. Is this
possible? If not, can anyone suggest how this could be implemented?

Thanks,

G Rodriguez

Re: HTTP video source serves individual JPEG images

Kocsis Tibor
Maybe you should request the frames manually and use appsrc to push
jpeg images as buffers into a decoding pipeline.

You'd need to modify souphttpsrc to support this. We wouldn't want to have the souphttpsrc element reconnect by default after the video ends, of course, so it should be indicated with a property.

Implementing this is unfortunately non-trivial, because of the multithread behaviour of souphttpsrc. In the gst_soup_http_src_got_body_cb() and gst_soup_http_src_finished_cb(), you need to re-send the message rather than sending EOS. You can try to set src->read_position to 0 and src->retry to TRUE, but I'm afraid it won't be that simple...

Regards,

Arnout

In reply to this post by Guillermo Rodriguez Garcia
For those sources I would suggest to periodically set the pipeline to
NULL when you
get an EOS event. When you want to get a new image, set it back to PLAYING,
and then you repeat this.

Re: HTTP video source serves individual JPEG images

Good idea, but wouldn't that wreak havoc on the output file in case it's a filesink instead of an xvimagesink?

Re: HTTP video source serves individual JPEG images

I think the file would just be overwritten with new contents because
the filesink
would reopen (not in append mode) the file.

Re: HTTP video source serves individual JPEG images

Wim Taymans
You could also wrap the source and decoder in a bin, patch up a buffer
timestamp,
catch the EOS event, set things to NULL internally and schedule a timeout for
the next frame. You could then more easily mux things.

There's the curlsrc plugin, which was implemented by its original author for the same purpose.
You could download and try it.

Dear Wim, Arnout,

Thank you very much for your answers, I'll have a look and if I get somewhere
