how to input 1 audio pipe + 1 video pipe ?
by fredericbochmann＠sympatico.ca 24 Sep '05

24 Sep '05

I have a program that I?ve called ?audio_pin? and another that is ?video_pin? they each take several arguments and each output a audio stream and a video stream respectively. I can easily hock my video_pin to ffmpeg like so: video_pin -i videoInputFileAudioLess.mpg - | ffmpeg -f mpeg -i - output.avi And I can easily hock my audio_pin to ffmpeg like so: audio_pin -i audio.wav - | ffmpeg -f wav -i - output.mp3 Now my question is, how can I merge ?audio_pin? ?s output and ?video_pin? ?s output to create a avi that contains audio and video? Thanks in advance Fredz./

Error when encoding mpeg...
by blobster＠tpg.com.au 23 Sep '05

Hi there, I'm trying to encode several thousand frames of POV-ray rendered animation into an mpeg movie using ffmpeg. The frames are called 'framennnn.png' where 'nnnn' is the frame number, and I use this command to set ffmpeg going... $ ffmpeg -i frame%04d.png -target dvd -b 6000 animation.mpg ...but I get this error... *** glibc detected *** double free or corruption (!prev): I grabbed the x86_64 SuSE 9.3 rpm from packman, and it actually works for converting mjpeg encoded avi's into mpgs, but not for converting a pile of pngs into an mpg... Does anyone know of a workaround for this? I've so far tried to set the environment variable MALLOC_CHECK_ to zero, in the hope the error was minor and ffmpeg could continue...it wouldn't! :-( -- Kind regards, Chris Wilkinson, Brisbane, Australia.

silent mode?

Thanks for all. The 2 commands "2>null" and "2>>myLogFile.txt" works fine on command-line. The matter is coming from the coldfusion command which encapsulate the command-line. I have download an extra and nox it works fine. Didier

adding a image before a movie
by ducky＠flukiest.com 22 Sep '05

Does anyone know what switch that I should use if I wanted to add a image before a movie starts? I've look through the list and cannot seem to find anything. -newvideo? Basically I want to add a image with my companies logo before the movie starts. I currently convert all formats to .flv format, so I would like to add a image as the first frame.
