  • Safari on Yosemite doesn't get total media duration from init file of video generated using MP4Box

    30 avril 2015, par sonam

    I am trying to play HTML5 video using MediaSource Extesion. I am generating dash fragmnets using MP4Box. I am creating init fragment and respective dash fragments.

    I am creating mediasource and adding init fragment to it. When this is done, all the browsers where media source extension is supported(chrome, firefox developer version, android chrome, windows 8 IE11), return correct media duration. But the same doesn’t work with safari on Yosemite, where spec says media source is supported. So on safari, media duration is updated as and when data fragments are appended to it progressively. How can I make it work in safari ? Is there something that is missing from init fragment and how to add it ?

  • ffmpeg error during encoding : EOF timestamp not reliable

    5 décembre 2019, par Massimo Vantaggio

    I have noticed that some videos processed by the following command displays an error in the preliminary phase of the process :

    [Parsed_movie_0 @ 0x7fb06cf00d80] EOF timestamp not reliable

    All this happens while I’m testing the ffmpeg command line that generates the encoding with the specific required by dash :

    ffmpeg -y -i inputfile.mp4 -c:a aac -b:a 384k -ar 48000 -ac 2 -async 1 -c:v libx264 -x264opts keyint=60:min-keyint=60:no-scenecut -r 30 -b:v 2400k -maxrate 2400k -bufsize 1200k -t 3600 -vf "scale=-1:$size" -vf "movie=logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]" format.mp4

    It work fine with some videos with small duration but by testing with some movies downloaded it give this error and i believe that could be a problem for MP4Box when dashing which other errors.
    Does anyone have any notices about it ? Is the command line suitable for dash ?
    Thanks

  • Remove characters from string using cmd.exe batch file and ffmpeg

    26 décembre 2023, par user2498772

    Here is the code...

    


    @echo off
:: set paths (no quotes)
set ffmpeg=F:\Video\Ffmpeg\ffmpeg.exe
set infolder=F:\Downloads
set outfolder=F:\Video\Finished



@echo.
@echo on
for %%f in (%infolder%\*.mp4) do "%ffmpeg%" -i "%%~dpnf.mp4" -c copy "%outfolder%\%%~nf.mp4"
@echo off
if errorlevel 1 pause
@echo.


    


    This code converts an mpeg-dash file to mp4.
An mpeg-dash is a streaming file format.

    


    The input and output file looks like this : "filename - DASH_V.mp4". (no quotes)

    


    I would like the output file to have the " - DASH_V" removed, so it looks like "filename.mp4". (no quotes)

    


    Any help would be appreciated. Could be a quick fix like changing "%% dpnf -13.0.mp4" to last command, but I am clueless on syntax as you can see.

    


    Tried a million things and got nowhere. Clueless on syntax.
