  • Ffmpeg hardware acceleration unsupported formats betwen transpose and auto_scaler_0

    11 août 2021, par Eduard6421

    I am trying to develop a transoding service which makes use of nvidia hardware acceleration capabilities ( The gpu used in this process is a Tesla T4) ; I want to generate a mpeg-dash playlist for my video so that i can stream it ;

    


    ffmpeg -y -hwaccel cuda -hwaccel_output_format cuda -i mobil1.mp4 -c:v h264_nvenc -c:a aac  \
-map v:0 -b:v:0 1000k -maxrate:0 1500k -bufsize:0 2500k -filter:v:0 "scale_npp=1920:1080:force_original_aspect_ratio=decrease" -map 0:a -b:a 128k \
-f dash dash.mpd


    


    But when mobile videos are uploaded ( which have rotation metadata ) I encounter the following error :

    


    Impossible to convert between the formats supported by the filter 'transpose' and the filter 'auto_scaler_0'
Error reinitializing filters!
Failed to inject frame into filter network: Function not implemented
Error while processing the decoded data for stream #0:0


    


    How can i solve this issue ? I am using the following docker image :
jrottenberg/ffmpeg:4.4-nvidia

    


  • Python to generate a video mpd file (even a node package) [on hold]

    14 mars 2017, par Junior

    I am in the midst of developing a video streaming app and I’m currently stuck at the Adaptive Bitrate Streaming part.

    Is there a python or node module that can (run server-side and) generate a mpd file of a video after it is uploaded, this way it is easy to link the file to Dash.js.

    So to clarify, I would just upload my video and have the server generate an mpd file for the video. The next time I use Dash.js, i just attach this file.

    Thanks.

  • HLS for on demand streaming

    15 septembre 2017, par Awais fiaz

    I have been working on DASH (Dynamic adaptive streaming over http) in the past but as DASH is not supported on IOS based devices so i am moving to HLS (http live streaming) as it works on all devices.

    I am in need of a guide of HLS for on demand streaming to understand encoding flow and techniques being used in this process.

    i am using FFMPEG as encoding library PHP for server side scripting and apache2 as server.

    any help regarding this would be really appreciated thanks.
