Please test the following:

If you did not make any changes to the open_video and add_video functions of
the decoding_encoding example, it cannot work. For H264 you need to manually
define a set a of H264 private settings before opening the codec.

Hi All,
I'm now upgrading our application to use the latest ffmpeg version.
In old version the AAC decoder supports packed sample but the latest AAC
decoder only supports planar sample format.
Our application uses avcodec_decode_audio3(AVCodecContext *avctx, int16_t
*samples, int *frame_size_ptr

Please note that only libswresample is supported (and
shold therefore be used).

First 300+ calls to avpicture_alloc succeed; then the next one returns error
despite valid parameters in function call:

Hello,
I'm probably overlooking something but am a bit stuck trying to cross-compile
FFmpeg for win32 (on OS X), linking in libopenjpeg. I've grabbed the
libopenjpeg-1.5.1 binaries from openjpeg.org, but the the configure process
fails on the test app, not finding opj_version. What's the way ar
But the decoding_encoding example works for me without any changes. The problem
is if you just want to encode two frames and flush them all out. With 25 there
doesn't seem to be any issues.

Hello, I'm using FFMPEG to decode video streaming from an IP Camera. all seems
good but I try to decrease the CPU usage of my application when I decompress
several differents streams.
In fact, I have a dual core processor, and if I decode one stream, my CPU usage
is very low (so good). If I deco
All those presets I tried but didn't help.

Hm, i really dont believe your problem is the flushing part itself.
I wonder if the pkt you are sending to the encoder is initialized - at least
i cannot see how. There is a huge number of issues in avcodec_encode_video2
that occur when you send it a pkt that it did not expect.
Here is how
Tried your flushing method too but did not make a difference.
The only way I can get this to work correctly is if I never flush frames until
I know I'm at the end of the video stream. The problem is in my case I don't
