How to start ffprobe with Windows PowerShell
7 mars 2014, par sebastianI am using Zeranoes FFmpeg Builds for Windows and I can start the ff-prompt without installing anything. But how do I start
ff-prompt.bat
with Windows PowerShell ? I have tried a few things likeInvoke-Expression
or changing the$env:Path
but nothing seems to work, because all I get is the message"C :\Users\Administrator>ECHO OFF
bin\ffmpeg.exe could not be found."
Is it even possible to start ff-prompt with PowerShell ? Every suggestion / solution is more than welcome.
My goal is to have a solution that works like this here :
http://spreadys.wordpress.com/2012/12/03/ffprobe-and-windows-powershell/but I want to do that automatically for all my clips, thats why I need to start ffprobe with powershell.

rtmppkt : Handle extended timestamp field even for one-byte header
5 mars 2014, par Martin Panterrtmppkt : Handle extended timestamp field even for one-byte header
Related fix in "rtmpdump" :
https://repo.or.cz/w/rtmpdump.git/commitdiff/79459a2Adobe’s RTMP specification (21 Dec 2012), section 5.3.1.3 ("Extended
Timestamp"), says "this field is present in Type 3 chunks". Type 3 chunks are
those with the one-byte header size.This resolves intermittent hangs and segfaults caused by the read function,
and also includes an untested fix for the write function.The read function was tested with ABC (Australia) News 24 streams, however
they are probably restricted to only Australian internet addresses. Some of
the packets at the start of these streams seem to contain junk timestamp
fields, often requiring the extended field. Test command :avplay rtmp ://cp81899.live.edgefcs.net/live/news24-med@28772

ffmpeg missing blend filter
13 mars 2014, par user2927954I am working on android project using ffmpeg library. I followed instruction from : https://github.com/guardianproject/android-ffmpeg to build ffmpeg library for android. All are OK.
Now, i am testing filters that corresponding to video filter of this library such as : drawtext, scale, pad, ... Most of them worked fine, but i have problem with "blend" filter.
I try with commands : ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex blend=all_expr='if(eq(mod(X,2),mod(Y,2)),A,B)' -y out.mp4 and recieve error : no such blend filter.
Do you know how i configure to enable this filter ?
Here is the output result :
