  • Stream with ffmpeg over LAN ?

    5 septembre 2018, par Kalpit

    I’m trying to stream a mpegts file over LAN, with the command

    ffmpeg -re -i in.ts -vcodec copy -acodec copy -f mpegts "udp://localhost:5000/live/stream"

    And trying to capture 10s chunks of it over LAN(at server) at

    ffmpeg  -i udp://192.168.xx.xx:5000/live/stream -c copy -f segment -segment_time 10 -strftime 1 "in /%Y-%m-%d_%H-%M-%S.mp4"

    This isn’t working. I tested the stream in VLC, and there’s nothing to play.

    Now, I suspect this is a port issue, since FFMPEG doesnt seem to write/listen over the 5000 port specified. I used netstat to check, and there are no PID including ffmpeg on the port. However, the command

    ffmpeg  -i udp://127.0.0.1:5000/live/stream -c copy -f segment -segment_time 10 -strftime 1 "in/%Y-%m-%d_%H-%M-%S.mp4"

    generates the desired output on my machine(localhost), as does ffplay. Can anyone help ?

  • ffmpeg not producing duration value when converting a media file. If this media is used in an html player, seeking fails on some browsers

    4 décembre 2020, par David

    I'm asking this question because I didn't find information on the web and this seems to be uncommon issue. After a lot of trial and error I'm creating this answer for reference.

    


    I'm using python which runs the ffmpeg command to convert an MP4 into WEBM file. I noticed that some of the conversions didn't seek when displaying in the webpage but other webm files worked on the same server. I was converting from two different machines. The core problem was the ffmpeg command was using pipe during the conversion process on one machine and output directly to a file on the other.

    


    Apparently doing this doesn't populate the duration attribute in the file but if I ran ffmpeg with the same switches, same order and output to a file on the system, the duration attribute would populate.

    


    I was converting from MP4 to WEBM format using opus for the audio. This issue might only impact certain file types, webm as an example and not others.

    


  • How to create m3u8 playlist from mp4 video url ( stored in amazon S3 ) and store the video chunks ( .ts files) and .m3u8 file back to another S3 ?

    19 mai 2019, par dexter2019

    I am building an application where user can upload video and others can watch them later. I am aiming for HLS streaming of the video on the client side, for which the video format should be .m3u8. I am using node fluent-FFmpeg module to do the processing, however, I have a huge doubt, that, how to ensure that all the .ts files (chunks) are also stored back in s3 bucket along with the m3u8 file after ffmpeg processed the mp4 file ?

    Because the ffmpeg command only takes the location of the m3u8 file ? How handle it when I want the input and output location to be S3 ?

    Any help will be greatly appreciated.

    I am following the answer from this question Ffmpeg creating m3u8 from mp4, video file size , which is working absolutely fine in my local machine, how to achieve the same for s3 ?
