Try libavfilter, please see transcoding.c again for sream conversions, btw
keep in mind your code may broke during porting from C to C++ or or vice
versa.

How can I get link to this iscussion for snding to others?

Hi all
OPW (Outreach Program for Women) is twice per year (compared to google
summer of code which is just once a year)
FFmpeg can participate in the next round but we need to fund at least
1 intern/student (6250 USD) for that. OPW is not run by a large
corporation with deep pockets.
Thus my mai
I solved the issue. I don't know why. but in C++ buffer size outbuf_size =
10; was too small, so increase of buffer size solves the problem.
Thanks for everyone who read it

Hello.
I have a problem with avcodec_encode_video2.
I send h263 video stream to network, this code works when I compile it with
C, but when I try to use C++ classes it crashes.
Can anyone help me?

yes, I mean transcoding.c, also output example has audio example

You can google for output example, there are example of using it uses
buffers encode_video, but it's deprecated function, but I'm sure libav has
some replacement for this

Thanks for your quick response. I could store the audio stream in a buffer
and then decode the buffer and output to a new buffer, does that sound OK?
BUT I don't know how to decode from a buffer :(
you mean the transcoding.c example?

FFmpeg has transcoding example, but it doesn't work with network because it
can't detect the output format, you can set it manually (edit the code). I
tested it for udp, so currently I have udp video stream.
Ofcourse I made my code, but after investigation ot transcode example, so
the code is works
Hi:
I am doing audio stream transcoding things, the scenario is that I keep
receiving audio data through HTTP protocol, storing it in memory buffer and
meanwhile I have to transcode it to the required target format for further
use. The original audio data may come in various formats. So the whole
I am currently trying to convert a raw PCM Float buffer to an OGG encoded
file. I tried several library to do the encoding process and I finally
chose libavcodec.
What I precisely want to do is get the float buffer ([-1;1]) provided by my
audio library and turn it to a char buffer of encoded ogg d
