H264最大的nal size限制无效

更新下 develop 分支的代码试一下，不超过 1500 的话，可以配置得更小一些，比如 1200

void os_log_error(const char* tag, const char* msg, va_list list)会崩

看下为啥崩，是输入什么了

void os_log_error(const char* tag, const char* msg, va_list list)会崩

有个 mpp_log_test 测试用例，跑一下看看~

Reduce H265 decoding latency

Do you check the packet and frame with the same pts? And also the stream reroder feature may effect the frame output order. Try control IMMEDIATE_OUT for decoding order output.

Reduce H265 decoding latency

If you can split the stream into a packet with the whole frame then you can set MPP_DEC_SET_PARSER_SPLIT_MODE to zero.

Reduce H265 decoding latency

I mean split the stream before put_packet

Reduce H265 decoding latency

Just enable MPP_DEC_SET_PARSER_SPLIT_MODE and send packet by slice or by length. Refer to mpi_dec_test or mpi_dec_mt_test.

Reduce H265 decoding latency

The hardware driver supports only frame by frame decoding so all slice in one frame should be all collected then start the hardware decoding.

如何在Python中使用MPP

目前不支持 python，需要做图像拷贝会影响效率

How to request stride alignment when decoding

Yes, 64 align is ok for mpp. But for some resolution like 4096 width the hardware performance is lower then expected. So we use 256 odd align to keep the...
