• getting errors from FFMpeg when spawned from .NET

  18 mars 2014, par Brannon

  When I run FFMpeg from the command line like this

  ffmpeg.exe -hwaccel auto -re -i "C:\Users\Public\Videos\Sample Videos\Wildlife.wmv" -an -sn -c:v bmp -pix_fmt bgr24 -f rawvideo - > junk.bin

  it works fine. However, when I spawn the exact same thing (minus > junk.bin) I get this nasty "bad header" error after a few seconds of playback. What is causing this ? I have trouble believing my process blocks the pipe longer than the filesystem does, but it should be able to block the pipe indefinitely without defeating the decoding. The truncated stderr is below. My code to spawn the thing is here.

• Buffer overrun Blackmagic Intensity 4K as input to FFmpeg

  24 mai 2016, par colossus47

  I am trying to take direct video output from a 4k Sony Handycam, via HDMI directly into a Blackmagic Intensity Pro 4K. I can verify that the camera, Hdmi and blackmagic card are working as I can capture and view video using the provided "Media Express" program. When use ffmpeg I do get video output but I also get a buffer overrun.

  Here is the command :

  time ffmpeg -f decklink -i "Intensity Pro 4K@20" -c:v nvenc -b:v 100M -vf yadif=0:-1:0" -pix_fmt yuv420p -crf 29.97 -strict -2 output.mp4

  And I get the following output :

  But whatever setting i try the video ends up very laggy and the duration ends up much longer than the original file, even when I play it through VLC. It is a little hard to explain so I will provide a sample file here with the result after the conversion :

  Is it something wrong with the file or with ffmpeg itself and how do I solve it ?

  


  Firstly I tried this command :

  


  ffmpeg -i "G:\test\test.ts" -map 0:0 -map 0:1 -vcodec libx265 -crf 23 -filter:v yadif=1 -acodec ac3 -ab 384k "C:\Users\User name\Videos\test.mkv"


  


  And then I tried this with the same result :

  


  ffmpeg -i "G:\test\test.ts" -map 0:0 -map 0:1 -vcodec copy -acodec copy "C:\Users\User name\Videos\test.mkv"


  


  The sample file is converted with the first command.
