  • FFMpeg Concat Error - What needs to be changed ?

    19 avril 2018, par Andrew Baldinger

    I have a tv episode video (let’s say episode.mp4). I also have a short, 20 second closing credit video that I want to append to various episodes (let’s say closing.mp4) The episode and closing are always Mp4, h264. The frame sizes are also the same. The audio codecs do vary, though. I would like to concat using concat demuxer to avoid having to re-encode. I tried doing this, but it gives me an error. I would like to make any necessary encoding changes to the short closing clip (so I would create multiple closing files, each matching the main episode file I want to add it to). What do I need to additionally make sure matches with the two videos to be able to use concat demuxer ? How would I edit the closing clip to match the episode ?

    Here is a probe of the ending clip :

    I created a version of the ending with the same screen size and audio codec as the episode. But, when I try to concat, the resulting video is much longer (1:03:00) than it should be (about 42 mins), and it freezes when played. Here is the concat :

  • ffmpeg livestream alway stop after 160hours streamming

    2 avril 2018, par JerryJumper88

    I use ffmpeg with this code to run stream youtube 24/7 from Windows VPS. But stream alway stop after 160-167 hours and I don’t know why.

       dir/b/s "C:\Users\NASA\Desktop\ffmpeg\bin\1\*.mp4" > list.txt
    
:encode video
    
:loop
    
for /F "delims=;" %%F in (list.txt)  DO ffmpeg -re -i "%%F" -vcodec libx264 -preset veryfast -maxrate 2500k -bufsize 3368k -vf "format=yuv420p" -g 60 -acodec libmp3lame -b:a 198k -ar 44100 -metadata title="" -metadata artist="" -metadata album_artist="" -metadata album="" -metadata date="" -metadata track="" -metadata genre="" -metadata publisher="" -metadata encoded_by="" -metadata copyright="" -metadata composer="" -metadata performer="" -metadata TIT1="" -metadata TIT3="" -metadata disc="" -metadata TKEY="" -metadata TBPM="" -metadata language="eng" -metadata encoder="" -f flv -s 1280x720 rtmp://a.rtmp.youtube.com/live2/xxxx-xxxx-xxxx-xxxx
    
goto loop

    And this is stream log. I google " Larger timestamp than 24-bit : 0xffffff9f" but nothing about this error. I contacted to admin server system, he comfirmed that has no issue connection. Then I tried again in Windows 7 and Windows server 2012, same result, still drop after 160h on youtube.

        Larger timestamp than 24-bit: 0xffffff9f

  • ffmpeg : StreamNotFound error

    27 janvier 2017, par KMG

    I’m using Adobe Media server and push streams to this server using FMLE.

    My stream name : appvideo

    When I tried to pull the video from the server using ffmpeg/ffplay, I’m not getting "stream not found error". Whereas rtmpdump can stream the video.

    After I see the logs, all the ffmpeg request logs have a stream name with extension .flv like [appvideo.flv]. But rtmpdump not append this extension [ like appvideo].

    FFMpeg/ffplay log in Media server :

    play    stream  2017-01-27  02:26:17    GMT appvideo    10.11.12.202    32715   11  17  _defaultRoot_   _defaultVHost_  live    _definst_   0   404 183.82.250.50   rtmp    -   rtmp://10.11.12.202:443/live    rtmp://10.11.12.202:443/live    -   --  4702122229742256497 3135    3631    normal  appvideo    -   -   rtmp://10.11.12.202:443/live/appvideo.flv   rtmp://10.11.12.202:443/live/appvideo.flv   -   flv 0   0.000000    0   -   0   0   -   -   -   -   1   -   --  -   -   -   -   -   -   -1  -1.000000   -

    Not sure why request append .flv extension at last like this : rtmp ://10.11.12.202:443/live/appvideo.flv
