Hey all,

we are currently facing a problem with the i.MX6DL and MPEG4-2 encoded videos.
The decoder seem to fail to decode videos of certain resolutions (video output becomes green).
For the latest test run, we used Linux kernel 5.4.2 and GStreamer version 1.16.1.

When hunting the problem down, it seems like the problem is related to the YUY2 (= YUYV) output format.
Unfortunately, gst always takes YUY2 as the default format for the v4l2mpeg4dec sink pad and 
forcing a different format does not work (video becomes even more green).

We saw commit d40e98c13b3e7cb1aa16e9c14f35db3c8c3dd033, which added YUYV if VDOA is used,
but could not find anything related in the i.MX 6Dual/6Quad VPU API Linux Reference Manual except:
"One pixel value of a component occupies one byte and the frame data is in YCbCr 4:2:0 format 
for H.264, H.264 and MPEG-4 codecs." [sic] (Rev. L3.0.35_1.1.0, 01/2013)

For debug purposes, we changed the dst_formats of the decoder driver to only support YUV420 (= I420).
All tested resolutions are working with this setup.

Does anyone else face similar issues?

Please just drop me a mail if we should perform further debug actions or provide further debug output.

BR,
Benjamin

The VDOA is documented in the "i.MX 6Dual/6Quad Applications Processor
Reference Manual" because it is not part of the VPU IP core, but an
i.MX-specific adapter between the VPU and the IPU. It is managed by the
coda driver to provide a better abstraction to user space.

If you use a different format other than YUYV (or disable the VDOA
using the disable_vdoa module parameter), you bypass the VDOA and
directly get whatever the VPU is producing.

Not sure if I understand correctly. Did you remove all other formats
except for YUV420 from the driver? Once you did that, all resolutions
are decoded correctly? What happens if you force the driver to produce
NV12 as destination format?

The height of the working resolutions seems to be a multiple of 16,
which is the macroblock size. Thus, there might be a problem with the
cropping the destination frames. Do you see the problems only with
videos that are encoded by the CODA or also with other mpeg4 encoded
videos?

Hi Michael,

thanks for your fast reply.

> Did you remove all other formats except for YUV420 from the driver? 

Exactly.

> Once you did that, all resolutions are decoded correctly?

Exactly.
But it happens very often that decoding the resolutions 320x200 and 400x300 
fails completely (see log on bottom). This occurs independent from the format in use.
However, independent from that, the decoding is correct, even on videos with a height
not divisible by 16.

> What happens if you force the driver to produce NV12 as destination format?

Artefacts appear on the top of each video with a height not divisible by 16.
The amount of incorrect pixel rows varies.
For example, with 480x500 the top 23 pixel rows and with 400x270 the top 3 pixel rows 
are "wrong".
We again removed all other formats in the driver.

> The height of the working resolutions seems to be a multiple of 16, 
> which is the macroblock size. 

We can confirm that. 
We tried a couple more heights, the problem seems to be related to that.
However, the width seems to have no influence.

> Do you see the problems only with videos that are encoded by the CODA or
> also with other mpeg4 encoded videos?

We also tried videos that are encoded with libxvid with the same outcome.


For further debugging, we also disabled the VDOA (by setting disable_vdoa=1) with the unmodified driver.
The result is exactly the same as forcing the I420 with a gst filter, as previously described.
The decoded output turns out to be completely green, also for "working resolutions".

Another finding, when modifying the driver: 
When forcing NV12, the VDOA is only enabled on the two "working resolutions" (dmesg output).
When forcing YUV420, the VDOA is always disabled (dmesg output).

BR,
Benjamin

Hey Michael,

any news from your side?
We did some further testing with MPEG4-2 videos and the new 5.5 kernel.

Summary:
1.) decoding of videos with a height not divisible by 16 (macroblock size) brings erroneous pixels/fragments in the top area.
2.) decoding of videos with BVOP2 (2 B-Frames) [a] results in macroblock errors [1].
3.) decoding of "static" videos with low bitrates and a GoP size > 1 results in timeouts [2].
4.) encoded videos with low bitrates and GoP size > 1 show ffmpeg errors [3] during re-encoding with a different tag (in software) [b].

ad 1.)
When running [c], the fragments are not shown.
But when the stream is stored in a file and then played (as in [d]), some of the top pixel rows are erroneous.
These fragments also occur on other videos, encoded with different software libraries.

ad 3.)
This is especially the case if the video is static and the size of a P-frame packet is low.
Can e.g. be reproduced with [e], but also happens during decoding with in software encoded videos with similar attributes.
The size of a P-frame packet of such a video is around 94 bytes. Is it possible that there is a limitation regarding minimum packet size?

ad 4.)
Did [b] with a bitrate from 100k to 2M in 25k steps and a GoP size from 1 to 16.
The following combinations result in at least P-frame errors. Some also contain I-frame errors, as can be seen in [3]:
100k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
125k: 4, 5, 7, 8, 9, 10, 13, 14, 15
150k: 4, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
175k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
200k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
225k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
250k: 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
275k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
300k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
325k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
350k: 2, 3, 4, 6, 7, 8, 9, 10
375k: 2, 3, 4, 5, 6, 7, 8, 10
400k: 2, 3, 4, 5, 6, 7, 9, 10, 11, 13, 15, 16
425k: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16
450k: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
475k: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15
500k: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
525k: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16

GoP size of 1 did not show any errors.

=> Point 3.) and 4.) might be related?

Also noticeable: The expected/configured bitrate strongly varies from the detected bitrate.


If you need further info or if we should take further actions, just drop us a mail.

thanks & br,
Benjamin
