  • Video created via shell_exec() does not play, but video created via terminal does

    25 février 2021, par Mukul Kashyap

    I am creating a video from single audio and single image and it is fine when the audio length less than 10 seconds but when the audio length exceeds 10 seconds then video not playing. I am using FFmpeg to create video using shell_exec().
The video is fine when I directly runs the FFmpeg command on the terminal but the only issue comes with the shell_exec command.

    


    This command I am using -

    


    ffmpeg -loop 1 -f image2 -i $this->img_url -i  $this->audio_url -vf scale=1920*1080 -pix_fmt yuv420p -vcodec libx264 -shortest ".$video_local_dir.$video_name;


    


  • How to transcode HLS video (with .m3u8 subtitle file) for MPEG-DASH stream using FFMPEG ?

    15 mai 2017, par Toan Tran

    I’m trying to use ffmpeg to transcode a HLS video.m3u8, which uses a .m3u8 subtitle file, for MPEG-DASH streaming. The subtitle file has been defined in the master manifest video.m3u8 but I receive only the video and audio, the subtitle doesn’t come along. What am I doing wrong ? Your help is very much appreciated.

    This is the command I used :

    ffmpeg -i http://myserver_ip/video.m3u8 -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://myserver_ip/dash/SampleVideo

    This is my video.m3u8 master manifest file :
