What is the input format for mpi_enc about mpp HOT 15 CLOSED

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:

• Input buffer: It already has had data.
• Output packet: data has had same size with "0 0 0 0 .." value.
  And the mpi_enc_test has not reported any problem.
  The output video is unuseable.
  As I think, maybe:
• mpi_enc_test needs a specific input format.
• Encode module auto recognizes that the input buffer is incorrect format and it gives me the wrong result, doesn't it?

from mpp.

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

from mpp.

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?

from mpp.

@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

from mpp.

@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.

from mpp.

@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.

@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 [email protected]

from mpp.

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

@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.

from mpp.

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?
