Hi,
I am having problems programmatically extracting metadata like size
and pixel format from a dpx image using a custom AVIOContext. Should
that work or does the image2 demuxer only work with files even in the
single-file case? Or is there something I need to watch out for when
using it this
I want to read a video stream from a UDP address using libavcodec functions. To
do so, I use the following code:
char *url = udp://127.0.0.1:1000;
AVFormatContext *oc = NULL;
avformat_open_input(oc, url, NULL , NULL);
If we run this code, then function avformat_open_input starts listening on

Thanks for the response, it works! :) I was thinking to put such a code within
a thread. Whenever avformat_open_input finds a stream at the given address,
then the thread can be terminated. In the meantime, the program can do other
stuffs. But do you know how I can make a thread with libavcodec

Hi guys,
I am trying to do a stream player in android but I need to read a array of
bytes and then decode every packet of array of bytes. In the end started to
make my AAC decoder work with the ffmpeg example of decoder. But I ran into
the same problem of this guy:

Thank you for correcting me!
There is also a image2pipe, which can read the data from a avio
context, but in my experience it also didn't work properly because its
designed for a pipe scenario where

Yeah it only works on img formats which have a
parser to re-assemble full images, so its use is
a bit limited.
Note that I (?) implemented -frame_size for image
formats with constant frame size.

Marcelo, have you initialized the ffmpeg using av_register_all()?
Also, when building the ffmpeg, have you included encoding/decoding/
parsing support for aac?
