Error - not working
prof-rt opened this issue · 12 comments
Unfortunately I can't get it to work:
Please note that i compiled this as a dynamic module, using the stock nginx deb dist 1.12.2, I hope this should not make major difference.
ffmpeg ouput:

I used nginx-1.12.2 stable version from official site, but can't reproduce the error. Could you please paste your conf file?
I initially used the example you provided, then tried to simply based on a working example that I had from the original ngx_rtmp_module.

I've tried my best to reproduce the error, but unfortunately, I haven’t made any progress until now. The differences of environment between you and me now are only Linux kernel and gcc versions.
From your error.log, I found a clue on stackoverflow: https://stackoverflow.com/questions/1345670/stack-smashing-detected, that may be the reason.
At last, I advise you to compile nginx with an option '--with-debug', otherwise setting 'debug' for 'error_log' directive makes no sense. Note that if you do so, nginx will log huge information in error.log, but that may be of great help to find out the reason of the error.
ok, the above problem is due to one of my configure settings:

I went back to basics:
nginx src: 1.12.2 from deb src from nginx.org
your vanilla nginx-http-flv-module
I compiled with this option:
:/usr/src/nginx-1.12.2/objs# ./nginx -V
nginx version: nginx/1.12.2

and this compiled, and executed well.
however!
I can't get the video to stream!!
ffmpeg -re -i test2.mp4 -vcodec copy -acodec copy -f flv rtmp://localhost/myapp/mystream -- works

OK, I reproduced the error, turn off the 'gop_cache' directive or comment it out to see if it works, there is a bug. Turning off it will take you a longer time to see the first picture of the video.
Thanks your patient test!
Unfortunately still doesn't work

I had some success with commenting out chunked on; this allowed me to view video in vlc and mpv.
However i could not get flv.js or videojs-flvjs to work in a browser.
So it is certain that mpv doesn't support HTTP chunked transmission, vlc supports both 'Expires: -1' and 'Transfer-Encoding: chunked' HTTP headers, so does OBS.
