Ok thank you.
As I do not control the input parameters I will go for the transcode
option. Is there an easy way to duplicate all required decoder parameters
to the encoder?

Like doing this, but with all important params in one step:


outst->codec->width = this->codec_ctx->width;
outst->codec->height = this->codec_ctx->height;
outst->codec->pix_fmt = this->codec_ctx->pix_fmt;
outst->codec->time_base = this->codec_ctx->time_base;
