Please streaming over nginx

Phat Nguyentan
Hi ffmpeg,
Please help me on this case:
I use openwrt and ffmpeg without h264 and libx264.  try to create m3u8 file
on nginx. I run command:
ffmpeg -loglevel verbose -re -i /dev/video0 -acodec libmp3lame -ar 44100
-ac 1 -f flv rtmp://localhost:1935/hls/movi
It's not working, can't create m3u8 file. When I change to linux with
-vcodec h264, it's working, but on openwrt we don't have codecs.
Thanks

"It's not working" is a very short report. It helps if you post the
complete, uncut console output. (Why would the format flv create an
m3u8? Or do you mean nginx creates the m3u8?)

Seeing that you already figured out that it's the missing codec: Have
you tried a different one? ffmpeg's default codec for flv should be
"flv1", and that is supported natively, without external libraries.

No codecs *at all*? You mean ffmpeg has no video encoders? Please show
us the output of
$ ffmpeg -codecs

Thanks.

Hi Moritz Barsnick,
Thank you so much to help me. Please check this link:
https://drive.google.com/open?id=1KpIVkt9WA0O2CDU3E9BjuSxPhcik8gto
(2 clips, and log ffmpeg -codecs)
Clip 1> Run ffmpeg on ubuntu and nginx server on ubuntu:
- command: ffmpeg -loglevel verbose -re -i /dev/video0 -vcodec libx264
-acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://192.168.1.11:1935/hls/movie
- result: move-01.ts (and movie.m3u8 later),
Clip 2> Run ffmpeg on openwrt:
- command: ffmpeg -loglevel verbose -re -i /dev/video0 -vcodec libx264
-acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://192.168.1.11:1935/hls/movie

- result: working ( but nginx can not create move-01.ts and movie.m3u8
later).
Please help me.

A friendly hint: Instead of creating 12 MB of videos, you could have
just copied the text from the console (after the demonstration) and
pasted it into the email, or into text documents to attach. It makes
it much easier for everyone to look at it.

Understood. This is how we expect it to work.

Which is pretty obvious.

Here, ffmpeg uses the "flv1" codec. Apparently, nginx has a problem
with that. Doesn't nginx have any log messages? /vog/log/httpd/ or
/var/log/apache/ or /var/log/nginx/? If it can't produce output from an
input, it should complain somewhere.

This documentation page:
https://github.com/arut/nginx-rtmp-module/wiki/Getting-started-with-nginx-rtmp#publishing-with-ffmpeg
says:

    RTMP supports only a limited number of codecs. The most popular
    RTMP video codecs are H264, Sorenson-H263 (aka flv) and audio
    codecs AAC, MP3, Nellymoser, Speex. If your video is encoded with
    these codecs (the most common pair is H264/AAC) then you do not
    need any conversion. Otherwise you need to convert video to one of
    supported codecs.

According to that, openwrt's ffmpeg encode to "flv1" should be just
fine! You could try "-vcodec h263" instead, but that's not quite flv,
IIUC.

Furthermore, you will notice another issue: ffmpeg on openwrt/mylinkit
encodes your 640x480 video with 30 fps at a rate of ~5 fps (0.158x).
That is *much* too slow for streaming. I assume the openwrt processor
(is this a router? a settop box?) is just not capable of encoding any
reasonable video. Sometimes, encoding can be tweaked to be faster
(while less efficient), but I don't see where we can gain a factor of
6. (I don't know the FLV1 flags - in x264, we can get it relatively
fast with a profile.)

Good luck,
Moritz

Re: Please streaming over nginx

Hi Moritz Barsnick,
I appreciate your help, I tried with h263, it's not support flv, but nerver
mind, I just want to ask you 1 question about hardware.
Can you recommend 1 development board to good use with ffmpeg? Now I use
linkit 7688 dou, It's not good to use ffmpeg (encoding video).
Thanks

There is no way to compile ffmpeg with libx264? Which other codecs are
available instead?

There is no codec declaration on your command. According to the ffmpeg
documentation the flv1 codec should be called as -vcodec flv on encoding

Re: Please streaming over nginx

Hi Micael Silva,
Thank you for your reply,
1> There are some codec in ffmpeg in openwrt, but no h264 or libx264. Maybe
there is a way to compile for openwrt but it's complicated.
2> codec flv1 for flv but not for nginx rtmp, like Moritz Barsnick said:
nginx rtmp only support h246 and h263(not for flv),
So now I figure out how to streaming without go to server or I will get new
device to working with ffmpeg well. If you know what way correct to video
streaming, please let me know.
Thank in advance.

The problem is that FLV1 is not compatible with HLS, as far as I know you
cannot put a FLV1 inside a MPEG transport stream therfore nginx rtmp will
be incompatible too. Maybe using RTMP only will work, HLS not.

If HLS is really needed it will need a ffmpeg version with H264 or some
sort of transcoder on the way.

Re: Please streaming over nginx

sirk98 qwerty89
Hello try to use this as nginx module server :
https://github.com/arut/nginx-ts-module

Using this module you don't need rtmp and flv container...
A simple schema is this :

ffmpeg -i some_file -f mpegts
http://nginx_ts_module/hls_incoming_stream_dir/some_file

ffplay -i
http://nginx_ts_module/hls_outgoing_stream_dir/some_file/index.m3u8

Re: Please streaming over nginx

Phat Nguyentan
Hi sirk98,
Thank you in advance, I  tried your solution and look like it's working
fine until the end(html play). m3u8 file is created, mpd file is created,
but those can't play. After little bit search I got:
https://github.com/arut/nginx-ts-module/issues/31
It's look like I always need libx264 encode. So I still use rtmp with flash
is acceptable solution right now.
Thanks
