FFMPEG with x264 encoding

Without a full version of your code it is hard to see what the actual problem is.

Firstly here is a working example of the FFMPEG library encoding RGB frames to a H264 video:

You could expand on this example by using CImage to load in your JPGs and pass the RGB data to the FFMPEG Class to encode to a H264 video.

A few thoughts on your example though:

• Have you called register all like below?

  avcodec_register_all(); av_register_all(); 

• Also I'd re-write your code to be something like below:

  AVStream *st; m_video_codec = avcodec_find_encoder(AV_CODEC_ID_H264); st = avformat_new_stream(_outputCodec, m_video_codec); _outputCodecContext = st->codec; _outputCodecContext->codec_id = m_fmt->video_codec; _outputCodecContext->bit_rate = m_AVIMOV_BPS; //Bits Per Second _outputCodecContext->width = m_AVIMOV_WIDTH; //Note Resolution must be a multiple of 2!! _outputCodecContext->height = m_AVIMOV_HEIGHT; //Note Resolution must be a multiple of 2!! _outputCodecContext->time_base.den = m_AVIMOV_FPS; //Frames per second _outputCodecContext->time_base.num = 1; _outputCodecContext->gop_size = m_AVIMOV_GOB; // Intra frames per x P frames _outputCodecContext->pix_fmt = AV_PIX_FMT_YUV420P;//Do not change this, H264 needs YUV format not RGB 

• And then you need to convert the RGB JPG picture to the YUV format using swscale as pogorskiy said.

Have a look at the linked example, I tested it on VC++2010 and it works perfectly and you can send it an RGB char array.
