• playback of ffmpeg converted video on LDPI device (Samsung S5300 240 x 320)

  25 décembre 2013, par user737486

  I have Full HD video taken by Samsung Galaxy S4 camera.
  video stream info as follows :

  {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"High","codec_type":"video","codec_time_base":"1\/180000","codec_tag_string":"avc1","codec_tag":"0x31637661","width":1920,"height":1080,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":40,"r_frame_rate":"30\/1","avg_frame_rate":"21240000\/707831","time_base":"1\/90000","start_pts":0,"start_time":"0.000000","duration_ts":1415662,"duration":"15.729578","bit_rate":"16553536","nb_frames":"472","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"rotate":"90","creation_time":"2013-12-24 10:19:18","language":"eng","handler_name":"VideoHandle"}}

  in short it is 1920x1080, 16KK bitrate, rotation : 90.
  I'm converting it using ffmpeg by the following command :

  ffmpeg -y -threads 8 -i input.mp4 -vcodec libx264 -vpre ipod640 -s 324x576 -strict -2 -b:v 512k -acodec aac -ac 1 -ar 16000 -ab 32000 -vf "transpose=1" -metadata:s:v:0 rotate=0  output.mp4

  The output video stream info :

   {"index":0,"codec_name":"h264","codec_long_name":"H.264 \/ AVC \/ MPEG-4 AVC \/ MPEG-4 part 10","profile":"Constrained Baseline","codec_type":"video","codec_time_base":"1\/48","codec_tag_string":"avc1","codec_tag":"0x31637661","width":324,"height":576,"has_b_frames":0,"sample_aspect_ratio":"0:1","display_aspect_ratio":"0:1","pix_fmt":"yuv420p","level":30,"r_frame_rate":"24\/1","avg_frame_rate":"24\/1","time_base":"1\/12288","start_pts":0,"start_time":"0.000000","duration_ts":72192,"duration":"5.875000","bit_rate":"521597","nb_frames":"141","disposition":{"default":1,"dub":0,"original":0,"comment":0,"lyrics":0,"karaoke":0,"forced":0,"hearing_impaired":0,"visual_impaired":0,"clean_effects":0,"attached_pic":0},"tags":{"language":"eng","handler_name":"VideoHandler"}}

  The output video being played without any problem, on many different devices and OSes including different iOs and androids, but Samsung S5300 doesn't play it. From the device log I can see the following exception :

  E/AwesomePlayer( 1349): This resolution [324X576] Not Supported

  But, when I change the width and height to 576x324 the video can be played on S5300, but in wrong rotation.
  What should I add in ffmpeg parameters to make it play in correct orientation ?

  ffmpeg version :

  ffmpeg version git-2013-12-22-911676c Copyright (c) 2000-2013 the FFmpeg developers built on Dec 22 2013 22:55:31 with gcc 4.4.5 (Debian 4.4.5-8)

  Thanks

• How to stream 24/7 on youtube (audio + video) with FFMPEG

  29 septembre 2023, par Carter510

  I plan to create a 24/7 stream with a video and a musical background which is located in a /Playlist folder.
I would like the music playlist to be played randomly and if a piece of music is corrupted or cannot be played, the program moves on to the next one.

  


  The problem is that with my command every time the music changes the stream stops.
Any suggestions ?

  


  #!/bin/bash

VBR="4500k"
FPS="30"
QUAL="superfast"

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="XXXX-XXXX-XXXX-XXXX"

VIDEO_SOURCE="fireplace.mkv"
AUDIO_FOLDER="/home/administrateur/Documents/Youtube/Playlist"

while true; do
    # Joue la vidéo en boucle
    ffmpeg -re -stream_loop -1 -i "$VIDEO_SOURCE" \
    -thread_queue_size 512 -i "$(find "$AUDIO_FOLDER" -type f -name "*.mp3" | shuf -n 1)" \
    -map 0:v:0 -map 1:a:0 \
    -map_metadata:g 1:g \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 6 -qscale:v 3 -b:a 320000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"
done


  


  I would like the fireplace.mkv video to play without interruption, for the music to be chosen randomly without ever stopping. And if one of the songs cannot be played, it is skipped.
