Creating farms of unique websites

VLC and ffplay not receiving video from RTMP stream on Nginx
14 janvier, par EkobaddI'm streaming via OBS 30.1.2 to an RTMP server on a digitalocean droplet. The server is running on nginx 1.26.0 using the RTMP plugin (libnginx-mod-rtmp in apt).


OBS is configured to output H.264-encoded, 1200kbps, 24fps, 1920x1080 video and aac-encoded, stereo, 44.1kHz, 160kbps audio.


Below is the minimal reproducible example. When I attempt to play the rtmp stream with ffplay or VLC, it's a random chance whether I get video or not. Audio is always fine. The output from ffplay or ffprobe (example below) occasionally does not show any video stream.


rtmp {
 server {
 listen 1935;
 chunk_size 4096;

 application ingest {
 live on;
 record off;

 allow publish <my ip="ip" address="address">;
 deny publish all;

 allow play all;
 }
 }
}
</my>

The server has two applications, "ingest" and "live", the former uses the following ffmpeg command to transcode the stream and create a corresponding stream on the latter application :


exec_push ffmpeg -i rtmp://localhost/ingest/$name -b:v 1200k -c:v libx264 -c:a aac -ar 44100 -ac 1 -f flv -preset veryfast -tune zerolatency rtmp://localhost/live/$name 2>>/tmp/rtmp-ingest-$name.log;


As you can see, this produces a log which shows the following :


Output #0, flv, to 'rtmp://localhost/live/ekobadd':
 Metadata:
 |RtmpSampleAccess: true
 Server : NGINX RTMP (github.com/arut/nginx-rtmp-module)
 displayWidth : 1920
 displayHeight : 1080
 fps : 23

 Stream #0:0: Audio: aac (LC) ([10][0][0][0] / 0x000A), 44100 Hz, mono, fltp, 69 kb/s
 Metadata:
 encoder : Lavc61.3.100 aac


The video is not present, though I can see on the digitalocean control panel that the server is pulling 1.2Mbps inbound, which is about the same as my OBS video bitrate. And, although the ffmpeg instance which is transcoding does not appear to see the video stream from the ingest application, ffprobe from my local machine does, sometimes :


> ffprobe rtmp://mydomain.com/ingest/ekobadd
...
Input #0, flv, from 'rtmp://mydomain.com/ingest/ekobadd': 0B f=0/0
 Metadata:
 |RtmpSampleAccess: true

 Stream #0:1: Video: h264 (High), yuv420p(tv, bt709, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 1228 kb/s, 23 fps, 23.98 tbr, 1k tbn
 126.24 A-V: -1.071 fd= 0 aq= 54KB vq= 161KB sq= 0B f=0/0


Sometimes, however, it doesn't see the stream at all :


[rtmp @ 0000022d87d0fe00] Server error: No such stream
rtmp://mydomain.com/ingest/ekobadd: Operation not permitted


Testing the stream with VLC gives the same results.


Of course, the "live" application also doesn't have video. I have, however, streamed video from it before. I assume if I restart nginx enough, that the exec_push ffmpeg command will randomly see the video stream much like ffprobe does. I also have HLS and DASH configured, and they're both working perfect if you're a radio talk show host.


/etc/nginx/nginx.conf : (I'm quite sure I never touched anything in the HTTP section, but it's included just in case)

Build FFmpeg with Freetype2 for ARM
28 avril 2016, par Pawel CalaI’m trying to build FFmpeg binary file with freetype library included ( I need it for drawtext filter ). Unfortunately I cannot configure ffmpeg properly and every try ends with "freetype not found" error.
PS I’ve tried to build guardian-ffmpeg project but i’m getting errors during configure process.
PS2 Building plain ffmpeg works perfectly well
Configuration script :
make distclean &./configure --target-os=linux \

make -j6 && make install || exit 0Directories sctructure :

-ffmpeg dirs/
-freetype2/
-rest of ffmpeg files ( including configure, make, etc )I’ve checked patch sources in guardian-project and I’ve found that ffmpeg configure file might need some changes in
require_libfreetypemethod ?!Thanks in advance ( and sorry for my bad english )
EDIT :
Building on OSX Mavericks,
Last 3 lines ofconfig.log; OSX hasn’t gotpkg-configthereforefalsein 2nd line :require_libfreetype

ERROR: freetype not foundEDIT :
SOLUTION !!!I’ve manadged to solve my issue. I’ve used Xubuntu 14.04 64bit + Freetype 2.5.3 + newest FFmpeg repo + install linux package "pkg_config" and small modifications in ffmpeg configure script ( find pkg_config and check initialization variable )

Why do I get different codecs on Windows and Linux with same code ?
27 janvier 2016, par user3277340I am using the API version of FFMPEG to generate a MP4 file from a series of images. I specify the output by calling
AVFormatContext *oc = NULL ;
avformat_alloc_output_context2 (&oc,NULL,"mp4",NULL) ;Running the exact same code on Windows and Linux I get different codecs assigned. On Windows, the value of oc->oformat->video_code is AV_CODEC_ID_H264 (28), but on Linux I get AV_CODEC_ID_MPEG4.
I tracked this down because on Windows my calls to avcodec_encode_video2(.,.,.,&got_packet) were always returning got_packet=0 so I never called av_interleaved_write_frame. I added a NULL AVFrame at the end to flush the video. But it was very small and did not contain the images I expected to see there.
But on Linux everything worked just fine. So I went ahead and manually changed the value of oc->oformat->video_code and I got the expected results.
My questions :
1) Why do I get different codec types on different platforms with the same code ? Is there a parameter I need to set to force MPEG4 ?
2) Is it "legal" to change this parameter after the call to avformat_alloc_output_context2 ? My concern is that "oc" has been properly initialized and, with the change, something may be inconsistent.
3) Is there a way to force the MPEG4 codec on any machine ?
Thanks.
