  • Cannot play audio with FFPLAY

    2 avril 2020, par Javier Urrestarazu

    I am trying to stream the sound of a Linux machine via UDP to a Windows 7 64 bit machine. The command for streaming the audio is :

    



    ./ffmpeg -f oss -i /dev/dsp -f mpegts udp://192.168.99.35:11222


    



    It seems to work well. However, when I try to play the audio with the following command :

    



    ffplay -fflags nobuffer udp://127.0.0.1:11222


    



    I get the following error : No more combinations to try audio open failed

    



    And nothing plays. I have no clue where the issue is coming from.

    


  • How to use ffmpeg faststart flag programmatically ?

    18 mars 2020, par Evgeniy Kharchenko

    I try to convert videos for playback on Android using H264, AAC codecs and mp4 container. Video plays normaly with non-system players. But system player shows error "Can't play this video".
I found out that the problem is in moov atom, which is writed in the end of the file.
When I use "-movflags +faststart" ffmeg flag to convert video, it plays normal, but when I try to do that programmatically, it gives no result. I use following code :

    



    av_dict_set( &dict, "movflags", "faststart", 0 );
ret = avformat_write_header( ofmt_ctx, &dict );


    


  • 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 !
