编码器找不到，但解码器可以找到
// 查找解码器
rk_h264_decodec = avcodec_find_decoder_by_name(DECODEC_NAME);
if (!rk_h264_decodec) {
std::cerr << "Codec '" << DECODEC_NAME << "' not found" << std::endl;
exit(1);
}
else
{
std::cerr << "decoder '" << DECODEC_NAME << "' found" << std::endl;
}

// 查找编码器
rk_hevc_encodec = avcodec_find_encoder_by_name(ENCODEC_NAME);
if (!rk_hevc_encodec) {
std::cerr << "Codec '" << ENCODEC_NAME << "' not found" << std::endl;
exit(1);
}
else
{
std::cerr << "encoder '" << ENCODEC_NAME << "' found" << std::endl;
}

运行结果是：decoder 'h264_rkmpp' found
Codec 'hevc_rkmpp' not found
