MJpeg and ZdcSocketStream>>upToAll:limit: DNU

That is old. I vaguely remember running that, it did work at the time.

Indeed #upToAll:limit: is SocketStream specific.

I guess you could just (try to) remove the #limit: part, it is just a kind of safety measure to stop when the boundary is not found (as the stream is unlimited).

Hi,

I’m trying to get a video stream in Pharo from a Pi video stream using this lib on the. Pi (https://github.com/jacksonliam/mjpg-streamer)

Then I found this library on Pharo (from 2013).

I had to change a method relative to Annoucment. #on:do: => #when:do:

Now I have a problem in Pharo 7 (same in Pharo 6) with ZdcSocketStream>>upToAll:limit:  (see pic)

Well, you could also try switching the socket stream class Zn uses to the old one:

ZnNetworkingUtils default socketStreamClass: SocketStream.

This is a global setting affecting all Zn operations.

And then move the #limit: back in.

I changed to #upTo:


I have no more DNU, but no streaming is shown beside the test image (I think it comes from MJpeg).

Testing on a public URL gives the same result… (webcam.st-malo.com).

I’ll try more (I’CCed the orignal author).

Thx Sven,

Worked like a charm ;)

Still some windows problem I guess: blue line. But cool :)

Any idea on how to get ZdcSocketStream work instead ?

Thnaks,
