MJPG stream is not working with kernel 3.18

[Aardvark]

There is no need for a kernel update. This is nothing wrong with the kernel and the bug report that had been filed for the kernel is now closed. Apps that are patched to properly work with the "bytesused" data behave correctly.

[jtlns]

Thanks for clarifying! So I'll have to wait for a future update of mjpg-streamer.

[mirak123]

Well, you can always apply the patch manually, it should be as easy as (raspberry) pie.

Thanks! Another MJPG_streamer happy user! I received my Pi 2 and thought the issue had something to do with the new board. But was wrong. Back up and running!

I also try to get this running on the Pi2, also tryed the fix, but get no picture/video in the browser. I use a usb webcam which works fine till now with gstreamer.

First I got the error:

$ mjpg_streamer
MJPG Streamer Version: svn rev: 3:172M
ERROR: could not find output plugin output_http.so
Perhaps you want to adjust the search path with:
# export LD_LIBRARY_PATH=/path/to/plugin/folder
dlopen: output_http.so: cannot open shared object file: No such file or directory

I could fix this with "export LD_LIBRARY_PATH=/usr/local/lib/"

when I start mjpg_streamer I get the following:

mjpg_streamer
MJPG Streamer Version: svn rev: 3:172M
o: www-folder-path...: disabled
o: HTTP TCP port.....: 8080
o: username:password.: disabled
o: commands..........: enabled

but the webpage at :8080 only shows:

404: Not Found!
Invalid input plugin number

The following brought me to the next step:

$ /usr/local/bin/mjpg_streamer -i "/usr/local/lib/input_uvc.so" -o "/usr/local/lib/output_http.so -w /usr/local/www"

Now I see in the browser the "MJPG-Streamer Demo Pages". But I get no picture or video. The full log is:

Is there any hints what I could do? Do I need to specify anything else for the video source?
Any help is appreciated

In case someone else also has problems, this worked for me:

[Karllebolla]

hello
First many thanks for this post.
When I call "patch -p0 <input_uvc_patch" always comes "File to patch:".
What file should I specify here?

[JustCullins]

yeah johnnya, those commands are not working out for it. are the commands made for the raspberry pi b+ module or raspberry pi 1

[charlielife]

Hi, guys:
I have the raspberry pi 2 with the last raspbian update and i was able to make mjpeg-streamer work with the following parametres:
./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -y f 15 -r 640x480" -o "./output_http.so -n -w /usr/local/www". It seems that -y and -n are very important in order to make the application run properly.

[charlielife]

I'm sorry, the correct input is:
./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -n -y f 15 -r 640x480" -o "./output_http.so -n -w /usr/local/www". Now it runs smoothly in my pi 2.

[JustCullins]

when i put both of those commands in i get a file not exists.

[trusk]

Sadly, the patch did not work for me. Tried patching multiple repositories of mjpg-streamer, and there was no difference, it did not work. But I'm glad I was able to downgrade to version 3.12 all to you guys, so thanks! Been using for about 4 moths with yuyv mode, which limited me to 1 or 2 FPS, and was awful. Now I can see my turtles while I'am at work, in full 720p glory at about 20-25fps.

So thanks community, again!

[braddo]

I'm attempting this patch and getting the following error:

Hunk #1 FAILED at 405.

Then the messages are so filled with double negatives I don't have any idea what they mean. I just accept the defaults over and over, hoping it didn't destroy anything :-/

[andrewtheart]

Thanks for the information everyone; this is an unfortunate bug.

I went though absolute hell getting guvcview 2.0.1 installed on Raspbian with kernel 3.18; PJ Assis's PPA on Launchpad didn't have an armhf version of the package.

However, I did find one ... just added the below to /etc/apt/sources.list

Code: Select all

deb http://ftp.de.debian.org/debian jessie main

then

Code: Select all

sudo apt-get update

and then 2.0.1 was available

[rriissee]

1) Download mjpg-streamer

Code: Select all

$ svn checkout svn://svn.code.sf.net/p/mjpg-streamer/code/ mjpg-streamer-code

2) Go to mjpg-streamer folder

Code: Select all

$ cd mjpg-streamer-code/mjpg-streamer

3) Safe the patch as some file, e.g. input_uvc_patch

Code: Select all

$ nano input_uvc_patch

Copy and paste the patch into input_uvc_patch file

Code: Select all

Can You help me please!!!!. I already done all steps from 1 - 5. But i have problem with step 6 "sudo make DESTDIR=/usr/local install"
I have message:

[daniel_moreink]

Hello there, I really hope I'm not alone with my problem.

Besides being absolutely new to working with Pi's, I actually managed to patch mjpeg-streamer with your help to actually use mjpeg instead of YUV and boost the fps from 3 to around 15-20. This works very well via the webinterface (IP:8080) and likewise with the VLC stream function. BUT - and this is where I am stuck - I can't find a way to have OMXPlayer (Pi A runs mjpeg-streamer, Pi B runs OMXPlayer) stream from Pi A. I tried different sources, like a mp4 video I put on my server, and there was no problem whatsoever.

Did anyone else have this issue and found a solution? Any Ideas?

Thanks a lot,
Daniel

[spotratz]

I am in the same situation as Daniel. Many thanks for the patch that worked flawlessly and help me get real time streaming to work correctly. But I am also interested in the other end with OMXPlayer. Any assistance with that would be awesome.

Steve

[jurmelius]

Well.. I have the same kind of problems with Jessie 03-2016.. Had to investigate myself and here is the solution

[user12345]

Why you make other people live very difficult?
You make a patch public, its clear the patch works only for a special Version of input_uvc.c an will fail at other Versions.
You dont give a source for the special Version.
Why to hell you dont upload a whole package of mjpg-streamer with included patched input_uvc.c???

The Patch didnt work, first it dont find the file. If you give it the full path it says "malformed patch at line 4"
