  • I could not encode using the Intel® Media Server Studio on the ZOTAC ZBOX PI225

    22 avril 2018, par Ubunkun

    I’ve succeeded to install the Intel® Media Server Studio to the

  • Destreamer (FFMPEG / Youtube-DL) - Can't download video, Invalid DTS, Invalid timestamps message

    1er avril 2020, par toprun91

    I'm using Destreamer a program that essentially lets you download microsoft stream videos by passing a key URL with a cookie down to Youtube-dl which then calls into ffmpeg.

    



    Whenever I try to download a video using this program I get tons of repeating lines of text (errors ?) like this :

    This continues to fill the screen and scroll with the same type of lines of text and then after a couple of hours it does eventually download the video but without sound.

    



    I am trying to work out why this is happening and why the video downloads without sound.

    



    Some key information :

    



      

    • I am using windows + powershell but also experience the same thing on
Linux (Kubuntu)

      • 


    • I am using the latest versions of FFMPEG, youtube-dl node.js

      • 


    • The program (destreamer) brings up a chromium window to authenticate.
In the Chromium window the video doesn't actually play properly and
gives Error code 0x20400003 The video plays fine in all other
browsers I have including Edge, Chrome, and Firefox

      • 


    



    Thanks for your help !

    


  • ffmpeg encoded mp4 with faststart not playing in firefox [duplicate]

    12 mars 2018, par adam smith

    This question already has an answer here :

    i am having problems getting mp4 files encoded by ffmpeg to play using firefox without it downloading the entire thing first ; while chrome plays immediately. I am using ffmpeg to encode the mp4 and applying ’-movflags faststart’ to make sure the moov atom is at the start, and i have used Atomic Parsely to check the output structure.

    I have checked that the server is using byte range etc, all good and other files are working well.

    I have compared the Atomic Parsely return from a file encoded using flipfactory that does playback in firefox immediately ; its moov atom contains a iod atom that is not present in the ffmpeg encoding.

    example of ffmpeg command :

    -i source_file_path -c:v libx264 -vf scale=1024 :-1 -preset veryfast -b:v 1000k -ac 2 -bsf:a aac_adtstoasc -b:a 128k -movflags faststart -f mp4 proxy_output_path

    i am not sure that adding the iod atom will resolve the issue, but thats all i can see that is different. I cannot however find anything in the ffmpeg documentation that seems to help.

    any recommendations for resolving using ffmpeg would be great.
