• I have a file that purports to be "uncompressed mov" that I want to convert to raw using ffmpeg

  9 août 2015, par Lyman Hurd

  I am running Ubuntu. Here is what I receive and also cannot play the movie with vlc or totem, however the sender insists that these files play on a Mac using QuickTime. Thoughts as to what might be wrong ?

  ~/bin/ffmpeg -i movie.mov ffmpeg version N-50051-g8d0757e Copyright (c) 2000-2013 the FFmpeg developers

  Here’s an "od -c" of the head which at least shows that the file isn’t raw :

• RTMP_ReadPacket, failed to read RTMP packet header

  14 juin 2018, par Dilivio Cat

  I am trying to livestream a 24/7 looping stream from my Ubuntu server to youtube.

  I have a gif that is looping and my music gets shuffled from a music list.

  for i in ./*.mp3 ; do echo "file '$i'" ; done | shuf >mp3list.txt ffmpeg -f 
  
  concat -i mp3list.txt -fflags +genpts -ignore_loop 0 -i giffilename.gif -f 
  
  flv rtmp://a.rtmp.youtube.com/live2/(mykeyhere)

  But I am getting this error when I run my script :

  RTMP_ReadPacket, failed to read RTMP packet header : Unknown error
  occutredm/live2/(mykeyhere)

  I did some research, but couldn’t find anything about this specific error. I opened port 1935 and it did not change anything.

  The OS is Ubuntu 16.04 on a VPS.
  Thanks for your help,

  Dilie

• Unable to get nginx-vod-module plugin to work

  31 octobre 2020, par AAP

  My first time trying hands on nginx-vod-module or any video streaming for that matter.
I just want to play static mp4 videos which I place on the server but via hls instead of direct mp4 access. No actual live streaming

  


  Q1. Am I right in understanding that a mp4 video which I place locally on my server, will automatically get broken down into segments for HLS ?

  


  My nginx installation is here : /opt/kaltura/nginx
The mp4 file is placed at /opt/kaltura/nginx/test/vid.mp4

  


  In ../nginx/conf/server.conf, I have this :

  


  location /hls/ {
            alias test/;
            vod hls;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 4000;

            include /opt/kaltura/nginx/conf/cors.conf;
        }
location / {
            root   html;
        }


  


  Now, I am able to access the m3u8 file :
curl http://104.167xxxxx/hls/vid.mp4/index.m3u8

  


  But when I try to open this file via VLC, I see these errors in errors.log :

  


  *2020/10/31 15:00:08 [error] 12749#0: *60 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-1-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:08 [error] 12752#0: *61 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-2-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:09 [error] 12749#0: *62 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-3-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:10 [error] 12751#0: *63 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-4-v1.ts HTTP/1.1", host: "104.167. ..."*


  


  Q2 : Is https must for this to work ?
Q3 : I dont see any /hls/vid.mp4 folder created anywhere on the server. Do I have to manually run ffmpeg separately to create the hls segments ?

  


  What wrong am I doing ?
