Hi,
I want to decode a video. The decoded datas are embedded in a AVFrame, and the
encode data will be encode in a AVPacket. In order to decode my video, I need
to tweak the AVCodecContex. The problem is that I don't know how to get the
informations I need to fill the AVCodecContext. Here is the sample of code :
AVFrame* dataDecode;//frame fill with the decoded data
codecContext->bit_rate = ???; codecContext->width = dataDecode->width;
codecContext->height = dataDecode->height; codecContext->pix_fmt = (enum
AVPixelFormat)dataDecode->format; /* frames per second */
codecContext->time_base= dataDecode->???; codecContext->gop_size = ???;
/* emit one intra frame every ??? frames */ codecContext->max_b_frames=
???;
How could I fill this attributes ? Do we need to fill this attributes if we
want to encode to a image ? By the way, which AVPixelFormat match with the
AV_CODEC_ID_JPEGLS codec ?
Thanks,Guillaume Bersac237bis rue de Pessac33000 Bordeaux06.65.30.89.43
