Re: Having trouble getting more than one chunk sent with chunked encoding

[Pedro Côrte-Real <pedro pedrocr net>]

Here is a minimal testcase extracted from my app:

https://github.com/pedrocr/camerasink/blob/c082d41c2427711a86f194c012277ca4ae4fc2f3/bin/testcase_libsoup.c

It listens on http://localhost:4000/mjpeg and shows the behavior I've described.

Any pointers would be most welcome.

Thanks,

Pedro
