  • How to play sequentially received video clips

    21 novembre 2017, par Ye Li

    I’m working on a prototype project in which some small video clips are sequentially sent over a network. These clips are chunked (using ffmpeg) from a complete video file. Each of the clips is separately playable (containing exactly one GOP). At the destination, I need to smoothly play the sequentially received files as if I were streaming the video, i.e., play the files at the receiver side one by one in one process. May I know whether this is doable ? And if yes, what is the best practice to do this task ?

    The network transmission/receiving parts are written in Python, but I’m open to use any other languages/tools for doing the task.

  • How can I stream then play YUV format with/without VLC/FFMPEG ?

    13 janvier 2023, par orfruit

    I'm able to play a local YUV file through VLC (as expected)

    


    .\vlc.exe --demux rawvideo --rawvid-fps 25 --rawvid-width 480 --rawvid-height 360 --rawvid-chroma I420 out.yuv


    


    Also FFPLAY is playing well

    


    .\ffplay.exe -f rawvideo -pixel_format yuv420p -video_size 480x360 out.yuv


    


    Conversion to YUV was done with FFMPEG

    


    .\ffmpeg.exe -i "video.mp4" -c:v rawvideo -pixel_format yuv420p out.yuv


    


    However, I'm not able o stream it and play'it over local network.
I know, it sounds crazy :) but I plan to use VLC as a monitor/debugger for some YUV data.

    


    The original MP4 file is streamed/played fine with VLC (test on the same computer)

    


    .\vlc.exe "video.mp4" --sout="#std{access=http, mux=ts, dst=:55555/}"
.\vlc.exe http://192.168.0.174:55555/


    


    So the big question !
How can I stream the YUV format and VLC recognise an play it as well ?

    


    All that I tried with VLC is not playable.

    


    Thanks for any hints !

    11 juillet 2017, par Cheng Jeiry

    I’m using Html5 audio api play m4a on IOS
    I converted mp3 to m4a by ffmpeg. here is the script

    ffmpeg -ss 0 -i ./Uploads/" + str(current) + ".mp3 -t 15 -c:a aac -b:a 64k ./Uploads/" + str(current) + "_lite.m4a

    then I play the m4a by audio api on IOS. and I got the error

    undefined:1 Uncaught (in promise) DOMException: Failed to load because no supported source was found.

    then a try mp3 mp4 format, works fine.

    Is there a solution to resolve this error ? Thank you very much !
