is it possible to get other sounds to a divx as it is with getting subtitles?
what is that format of that?
Yes, you can have multiple audio streams in your video file. Here's some more information (I'm guessing you're using AVI as your container format).

We have a Video file we want to stream it over UDP in mpegts.
This is working perfectly with ffmpeg API.
Now we want to add subtitle's to this stream.
i'll try to load subtitle file and add stream to our output context not working
i'll try to dynamicaly add subtitle not working too
If Anyone has an idea.
Thanks to all.
MPEG-TS format only supports DVBSUB or DVBTELETEXT formats and both are bitmap-based.
I am trying to generate a video with libavformat/Libavcodec with a bunch of images that are in memory.
Can someone point me in the right direction, please?
Thanks in advance.
First, the basics of creating a video from images with FFmpeg is explained here.
If you simply want to change/force the format and codec of your video, here is a good start.
For the raw FFmpeg documentation you could use the Video and Audio Format Conversion, the Codec Documentation, the Format Documentation the and the image2 demuxer documentation (this demuxer will manage images as an input).
If you just want to take images and make a simple video out of it, just look at the 2 first links. FFmpeg's documentation gives you powerful tools but don't use them if you don't need them.
A sample command to create a video from images is:
ffmpeg -i image-%03d.png video.mp4
This will take all the files in sequence from image-000.png to the highest number available and make a video out of it.
You can force the format with the extension of the output file. To force the video codec use -c:v followed by a codec name available in the codec documentation.
i'm looking for a script that can convert a video in 2 formats for my website :
mp4 and Webm
i also want it to create a jpeg of the first frame and make all at 640*360
I'm a begginer with ffmpeg so i don't really know where to start. this is what i have for the moment, but that doesn't work
ffmpeg -i /tmp/video.off /tmp/video.webm /tmp/video.mp4
the ideal situation is to have a drag and drop conversion tool, but a folder based can do the trick too
Thank you
I've a C# program generating JPEG images in realtime, i need to (continuously) generate a video from the images and stream it (also in realtime).
I've used ffmpeg to transcode an input video source and stream it, doesn't ffmpeg have an option to get the input as a set of images(always being generated) and make the video out of it ?
Cheers
Actually I used VLC for the streaming....
Actually I just found at that I could:
ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg
But i need to tell ffmpeg to keep doing it, I mean, if it doesn't find another image ffmpeg should wait for another one to be generated... is this possible ?
Anyone know how to convert a JPEG image to MPEG still frame format? I'd love to do it in java but a linux command line process would be ok. (I saw something on code project that does this for c sharp).
I haven't done it myself but here is an overview of converting JPEG's into MPEG's. I would take a look at using FFMPEG.
