Hi Roozbeh
I have this Sanyo camera which stream H.264 data. I'm just trying to decode the H.264 data received from this camera. According to the documentation I can use libavcodec To decode the data and display it and was just wondering how to do this...

You may use it's source code to understand APIs or samples, Download the binaries here: http://ffmpeg.arrozcru.com/builds/ Then, you may use output_example.c example in ffmpeg source code. It creates some images files, compress them and append them to video streams of files. You need to do this: 1- Create an .mp4 file or .h264 using libavformat functions 2- Create a video stream 3- Capture images from camera (probably using RTSP or HTTP protocols, I will tell you specifically if you tell me your camera model) 4- Append the frame captured from camera to video stream (DO NOT PASS THEM TO CODEC INTERFACE, YOUR FRAMES ARE ALREADY COMPRESSED) 5- Do 3,4 steps till something happens 6- Close Video Stream I did do that with ffmpeg and it works. So, just take your time and play with API and use output_example as your base sample. Let me know if you need additional help.
