• ffmpeg slideshow video from images creating empty mp4

  27 novembre 2017, par greenthumbtack

  I’m trying to use ffmpeg to create an .mp4 from a set of .JPG files. This is the ffmpeg line I’m using :

  ffmpeg -framerate 1/5 -i image-%03d.JPG output.mp4

  which returns :

  and a output.mp4. When I run this file, it ends immediately without showing any images. I don’t see any errors or problems in the code, so I’m not sure what I’m doing wrong. Do I need to increase the video framerate or something else ?

• FFmpeg : avconv and ffserver - connection reset by peer

  On another machine I can open the flv-stream via VLC by opening the address http://ip.running.ffserver:8090/live.flv.

  So why does it works step by step via the movie.flv file and not directly ?

  What is the difference between

  • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" movie.flv
    followed by
    ffmpeg -stream_loop -1 -i movie.flv http://localhost:8090/feed1.ffm and

  • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm ? Why ends this command with a av_interleaved_write_frame(): Connection reset by peer ?

• ffmpeg command not working from bash script but working from command line [duplicate]

  6 octobre 2023, par SamTech

  I wrote a bash script that is generating command to encode video and create HLS playlist.

  


  Here is the script. To make it short and clear, i fill variables with hard-coded values.

  


  #!/bin/bash

# below variables are generated from some other script

basic="-hide_banner -y -i Sample.mp4 -profile:v main -crf 20 -sc_threshold 0 -g 50 -keyint_min 50 -hls_time 6"

renditions="-c:v:0 h264 -filter:v:0 scale=w=426:h=240:force_original_aspect_ratio=decrease -b:v:0 128k -maxrate:v:0 136k -bufsize:v:0 192k -c:v:1 h264 -filter:v:1 scale=w=640:h=360:force_original_aspect_ratio=decrease -b:v:1 256k -maxrate:v:1 273k -bufsize:v:1 384k -b:a 128k -c:a aac -ar 48000 -ac 2"

mapping="-map 0:v -map 0:v -map 0:a"
stream_map="-var_stream_map \"v:0,agroup:audio v:1,agroup:audio a:0,agroup:audio\""

hls="-hls_list_size 0 -f hls -hls_playlist_type vod -hls_segment_type mpegts -master_pl_name master.m3u8 -y %v_seg.m3u8"

# show final command
echo "Command:"
echo "ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}"

# execute command
ffmpeg ${basic} ${renditions} ${mapping} ${stream_map} ${hls}


  


  Here is complete output from the script, along with the error it is giving.
