  • 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.

    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 ?

  • Where can I find my output video file after execution of ffmpeg command

    7 août 2019, par Giri Aakula

    I run this command to capture my screen

    ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

    I didn’t find the output.mp4 file anywhere in my HDD. I checked in the bin folder of ffmpeg it is not there.
    I searched the whole PC I didn’t find it anywhere. Can anyone please help me out to find the file.
    The console output is

    C:\Users\USER>ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4
