What is the input format for mpi_enc #1

Closed dalmatele closed 3 years ago

dalmatele commented 6 years ago

Hi, I've a problem when using MPP lib. I can not understand what type of data to input for MPP encode. When I feed data to mpi task, I always got the packet with same size.

HermanChen commented 6 years ago

mpi task is a container of MppFrame and MppPacket. You can refer to mpi_enc_test. There is sample of how to attach frame to task and send to mpp. Then output task will carry a packet with its length as its valid data size. The packet size is the fix buffer total length.

@HermanChen: Thanks for your reply. When I tried mpi_enc_test, I've given it an input file and I've outputed the value of input buffer and output data of packet but I've had the same problem:

And this is output I've dumped:

@dalmatele

  1. you should specify input data format in cmd line when use mpi_enc_test
  2. can you describe how you use it? such as how do you use mpi_enc_test like ./mpi_enc_test -i xxx -o xxx -f x -t x -w x -h x
  3. can you upload a input file and dump file?

the above may help us to deal your problem

dalmatele commented 6 years ago

This is my command: sudo ./mpi_enc_test -i ../../data/small.mp4 -w 560 -h 320 -f 4 -t 7 -d 2 -o output_enc.mp4 But, now I saw in kern.log: mpp_dev_ioctl:545: unknown mpp ioctl cmd 40086c03 Maybe we have something wrong in kernel?

sliver-chen commented 6 years ago

@dalmatele i see your cmd line sudo ./mpi_enc_test -i ../../data/small.mp4 -w 560 -h 320 -f 4 -t 7 -d 2 -o output_enc.mp4

  1. you specify the input file as small.mp4 so small.mp4 is a mp4 file? maybe you need to specify as a yuv file accroding to choosed format
dalmatele commented 6 years ago

@sliver-chen no, the extension is only my file's name. In fact that it's a YUV file. But my output_enc.mp4 is unusable. As I said above, maybe we have bug in kernel VPU driver.

sliver-chen commented 6 years ago

@dalmatele ok let we get more message from the error log you can set proc debug option to get more about it. just do like tihis, echo 0xffff > /sys/module/vcodec_service/parameters/debug it is a kernel debug switch,then wo can get more about error

and i suggest you test source file with ffmpeg using ffmpeg tools to identify it. ffmpeg -s 560x320 -i small.yuv output_enc.h264 then play it with vlc or elecard tools

Because i can get correctly compress stream by using mpi_enc_test So maybe we need above operating to check it.

Or you can provide your souce yuv file to me? i think it is the best method to resolve it. In addition to that，tell me your chip type.

Sorry, but I can not find this file. I've tried to change /sys/module/rk_vcodec/parameters/debug instead. But output is the same. I've attached my list of files in /sys/module directory. My chip is RK3328.

dalmatele commented 6 years ago

@sliver-chen Maybe I've known problem. In mpp_device.c we had:

define VPU_IOC_MAGIC 'l'

define VPU_IOC_SET_CLIENT_TYPE _IOW(VPU_IOC_MAGIC, 1, unsigned long)

define VPU_IOC_GET_HW_FUSE_STATUS _IOW(VPU_IOC_MAGIC, 2, unsigned long)

define VPU_IOC_SET_REG _IOW(VPU_IOC_MAGIC, 3, unsigned long)

define VPU_IOC_GET_REG _IOW(VPU_IOC_MAGIC, 4, unsigned long)

define VPU_IOC_PROBE_IOMMU_STATUS _IOR(VPU_IOC_MAGIC, 5, unsigned long)

define VPU_IOC_WRITE(nr, size) _IOC(_IOC_WRITE, VPU_IOC_MAGIC, (nr), (size))

But in kernel we defined, mpp_dev_common.h:

define MPP_IOC_MAGIC 'l'

define MPP_IOC_SET_CLIENT_TYPE _IOW(MPP_IOC_MAGIC, 1, u32)

define MPP_IOC_GET_HW_FUSE_STATUS _IOW(MPP_IOC_MAGIC, 2, u32)

define MPP_IOC_SET_REG _IOW(MPP_IOC_MAGIC, 3, u32)

define MPP_IOC_GET_REG _IOW(MPP_IOC_MAGIC, 4, u32)

define MPP_IOC_PROBE_IOMMU_STATUS _IOR(MPP_IOC_MAGIC, 5, u32)

@dalmatele please send your source file to my email to recurrence problem my email is sliver.chen@rock-chips.com

dalmatele commented 6 years ago

@sliver-chen I've sent you sample file. Please check it. Thank you.

sliver-chen commented 6 years ago

@dalmatele I get the correctly result in my board. With these check,i think maybe your kernel version is too late You had better to update it.

dalmatele commented 6 years ago

I've used this kernel: Linux rock64 4.4.77-rockchip-ayufan-93 #1 SMP Tue Aug 29 09:35:00 UTC 2017 aarch64 GNU/Linux I think it's the newest version. Can you show me your kernel version?
