• ffmpeg transcoding move to mp4

  16 août 2022, par Paul

  I currently use windows free software called : AnyVideoConverter to convert my iPhone huge MOV files to MP4s that can be played on other devices via my plex server.
I want to automate that process so it runs in the background on one of my linux machines.
However I am struggling to get it working. Here is what I have so far.

  


  Original file details :
Duration : 00:00:13.53
Original Video : 40MB
Video details : Stream #0:0(und) : Video : hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709), 3840x2160, 23453 kb/s, 30 fps, 30 tbr, 600 tbn, 600 tbc (default)

  


  AnyVideoConverted file :
File Size : 5MB
Video Details : Stream #0:0(und) : Video : h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 3840x2160, 2870 kb/s, 24 fps, 24 tbr, 12288 tbn, 48 tbc (default)

  


  This format works great on all my devices

  


  So far the closes I managed to get to that is this ffmpeg command :

  


  ffmpeg -i original.mov -c:v libx264 -profile:v baseline -maxrate 3M -bufsize 3M -c:a aac -b:a 128k x264.mp4


File size:5MB
Video details :     Stream #0:0(und) : Video : h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 2160x3840, 3063 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)

  


  problem is that when I try to play it via plex I get :

  


  Playback Error : This server is not powerful enough to convert video

  


  What am I doing wrong here ?

  


  My knowledge of ffmpeg or video encoding/transcoding is zero. Can someone advise me how to get my mov files converted to mp4 so they can be played via plex without additional transcoding by plex and without reducing the resolution size of the converted video.

  


  Any pointers ?
Thanks

  


• H.264 (MP4) video not play in IE9, but will play in Safari [closed]

  27 septembre 2011, par Austin S

  I have encoded a video using FFMPEG into three formats : WebM, MP4, and FLV. Chrome, Mozilla, and theoretically Opera (although I haven't tested it) should all use the WebM version. IE9, iOS devices, and Adriod should use the MP4 container. While all legacy browsers should default back to the flash version of the file. I'm using video-js to help serve the content. The content is set to preload and autoplay.

  I have found that everything is working as intended except for IE9, where all I get is the poster image and a white dot that typically spins indicating that the file is loading however it is not spinning in this scenario. The MP4 file opens in Safari, an iPad, an iPhone, and an Andriod - verifying that the file is infact legit.

  The following is the specs for the MP4 file when I stream it using VLC. I don't know if this is particularly useful, I'm just trying to provide as much detail as possible.

  VLC Codec Details

  • Stream 0

    Type : Video

    Codec : MPEG-4 Video (mp4v)

    Language : English

    Resolution : 480x270

    Frame rate : 2997

  • Stream 1

    Type : Audio

    Codec : MPEG AAC Audio (mp4a)

    Language : English

    Channels : Stereo

    Sample rate : 48000 Hz

  When accessing videojs.com from my coworkers computer, the video on their main page wouldn't play the video correctly in IE9, but we could hear the audio. When I went to another coworkers computer it played just fine. I'm wondering if IE9, or video-js, is tempermental depending on how updated your OS is.

  The fact that I'm working on XP with IE7 is making this all the more difficult to fix, so if you have any suggestions on what could point me in the right direction, I would greatly appreciate it !

  Thanks,

  Austin S

• My (FFMPEG issue ) RTMP server(freebsd) wont let me hear video when I play a huge file over the server itself :/

  19 avril 2021, par Engi Gang

  Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

  


  rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

  


  any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

  


  Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

  


  Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application live {
            allow play all;
            live on;
            record off;
            hls on;
            hls_nested on;
            hls_path /mnt/hls/;
            hls_fragment 2s;
        }
        
    }
}
