AM572x EVM fails to decode MP4 files

Leon Pollak

Other Parts Discussed in Thread: AM5728

Hello, all.

We are running the EVM with both SDK versions (see below) and trying to play the file of MP4 container with one h.264 encoded stream (from DM8148 board).
All known to us video players (VLC, WMP, ffplay, mplayer,...) play this file without a problem.
But our attempts to play it in te EVM fails (while some other originated files are played OK).

Here is the explanation:

*** PC with FC23 runs this command perfect:
gst-launch-0.10 filesrc location=/home/out.mp4 ! decodebin ! queue ! ffmpegcolorspace ! autovideosink

*** AM572x EVM - ERROR! (PSDK 2.0.2.11):

Hello,

In the pipeline which you are using I do not see demuxer, parser elements.
Please check this guide:

Thank you, Margarita.

I am afraid this is not the source of the problem, because there are files played by my pipe, but some files are not.

Nevertheless, I built the pipe as recommended by your link - still, this(!) file is not played by EVM, although it is played by all popular players including QT 7.6 for Windows.

Here is the pipe and logs:

Hello,

I see that the pipeline is moving to playing state (GstSystemClock) but execution is ended after 0:00:00.001146619.
Could you add gst-debug=3.
Could you replace kmssink with with " fakesink silent==false"?

Hello, Margarita.
It looks like we are moving, but still not clear the direction...:-)

Just to remind - the file is played perfect by all known players....
The last group of 9 log lines is repeated till the end of the mp4 file...

Hello,

I see there are codec errors.
Are you able to play this video stream when ffdec_h264 element?
Do you observe this problem only with this video stream?

Thank you, Margarita.

First, there is a strange thing: if we brake the pipe into two pipes inserting the filesink - the thing works!
See below:
- the (1) is the original pipe and log file.
- the (2) is the splitted pipe.
- the (3) is the PC Linux pipe working as you said. The problem is that we do not find ffdec_h264 in none of SDK we use. We are trying to find it still...

Finally, to your last question - all the files produced by the MP4V2 library (which generates the MP4 container from the h264 stream coming from DM8148) produce this kind of error. But only gstreamer in AM572x EVM has this problem. All other players and gstreamer in PC play these files without any issue.

Hello,

Leon Pollak said:

I am sorry this element is for gstreamer version 0.10.

You could try gst-inspect-1.0 | grep "dec" or gst-inspect-1.0 "avdec_h264"

Leon Pollak said:

I see you are playing this on version 0.10 on PC, what about if you play it with gstreamer version 1.0 on PC?

There are differences between both versions.

Thank you, Margarita!

Yes, the avdec_h264 exists in the 1.0 version. We tried it and it does not work too on the EVM.
Using the 1.0 gstreamer in PC works also - all PC variants of all versions work fine.

Note: We noticed that all files that are playable in the EVM are of progressive type, while files which fail to play are of interlaced type. May this be some cause of the issue? We do not understand how can it be, because splitting the pipe solves the problem, while splitting the pipe can't convert interlaced video to progressive type.

Thank you again.

0 Margarita Gashova over 7 years ago in reply to Leon Pollak

Hello,

When you splitting the pipeline you have this "'video/x-h264, stream-format=byte-stream'".
Could you share the stream?
Could you try :

gst-launch-1.0 filesrc location=out.mp4 ! qtdemux ! 'video/x-h264, stream-format=byte-stream' ! h264parse ! ducatih264dec ! fakesink

TI__Guru* 80190 points

Hello,

I remove the spaces from the link but I see error "video can't be played because the file is corrupt. "
Could you recheck the uploaded video file?

One more could you try this pipeline:
gst-launch-1.0 filesrc location=out.mp4 ! qtdemux ! h264parse ! 'video/x-h264, stream-format=byte-stream' ! ducatih264dec ! fakesink --gst-debug=3

It is like union between the both pipelines which was working for you
(2a. Work on ARM! (mp4 ---> file_h264 ---> display)
gst-launch-1.0 filesrc location=out.mp4 ! qtdemux ! h264parse ! 'video/x-h264, stream-format=byte-stream' ! filesink location=out.h264
2b.
gst-launch-1.0 filesrc location=out.h264 ! h264parse ! ducatih264dec ! kmssink).

When you trying with avdec_h264 what you observe on EVM? When you say that on PC is working with version 1.0 you tried with avdec_h264 element right?

Hi Leon,

I think I could help you with this issue. I was able to play a file of MP4 container with one h.264 encoded video. This was the pipeline I used:

I am using gstreamer 1.8.1 on AM5728 EVM Ridge-Run SDK image. You can follow this link ( https://developer.ridgerun.com/wiki/index.php?title=Gstreamer_pipelines_for_AM572x ), here you will find a set of gstreamer (1.8.1 version) tested pipelines for AM5728 EVM with RidgeRun SDK images.

I display the video on the on-board LCD and also trough HDMI port (by changing the connector on kmssink caps)

I hope I was able to help you.

================================================================================================================

After a quick review and debugging with GDB I could determine that the error is related with some wrong or missing metadata in the video buffers. There is something in the video that the ducatih264dec doesn't like, but this is what I take out only from a quick and superficial debug with gdb.

I tested the AM5728 EVM and ducatih264 decoder with a generated video with the same resolution of your sample video, and with progressive and interlaced mode; in all cases the pipeline executes well and the video was displayed.

Also, I tested on the AM5728 EVM the following pipelines with your out.mp4 sample video. This pipelines works perfectly and give no errors.

1) Decode the video with avdec_h264 software decoder and send it to a fakesink. From the out log, you can see a successful execution and buffers being processed and sent to the filesink

gst-launch-1.0 -e filesrc location=out.mp4 ! qtdemux ! h264parse ! avdec_h26
4 ! queue ! fakesink sync=true silent=false -v

OUT:

=====================================================================================================================

# gst-launch-1.0 -e filesrc location=out.mp4 ! qtdemux ! h264parse ! avdec_h26

2) Transcode the video. I run a pipeline on the EVM that decodes the video with avdec_h264 decoder and encoded again with openh264enc and send it to a filesink. Then I run another pipeline that decodes the video with ducatih264dec and displays it on the EVM LCD with kmssink. The pipeline work perfectly and the trasncoded video could be displayed without problems. This are the pipelines I used:

Transcode the video:

gst-launch-1.0 -e filesrc location=out.mp4 ! qtdemux ! avdec_h264 ! queue !
openh264enc ! qtmux ! filesink location=transcoded.mp4

Decode and play the video:

gst-launch-1.0 filesrc location= transcoded.mp4 ! qtdemux name=demux demux.v
ideo_0 ! 'video/x-h264, stream-format=avc' ! queue ! h264parse ! h264parse ! 'vi
deo/x-h264, stream-format=byte-stream' ! ducatih264dec ! kmssink scale=true conn
ector=30

Both videos (out.mp4 and transcode.mp4) are encoded in h264 and has an mp4 container. From mediainfo the principal difference I can see between the videos are:

File out.mp4:

-) Format : MPEG-4

-) Format profile : Base Media / Version 2

-) Codec ID : mp42

-) Format profile : High@L3.1

-) Format : AVC

-) Format/Info : Advanced Video Codec

File transcode.mp4:

-) Format : MPEG-4

-) Format profile : QuicTime

-) Codec ID : qt

-) Format profile : Baseline@L3.0

-) Format : AVC

-) Format/Info : Advanced Video Codec

I hope this info could help you.

Thank you, Daniel for spending time on our case.

From your extensive study I understand that you came to the same conclusion that we did: the Ducati element has some problem decoding our out.mp4.
This problem does not exist with any other element substituted instead of the Ducati decoder.
As far as I was able to understand, Margarita also agrees with this conclusion and TI are looking at the issue trying to evaluate and hopefully fix it.

So, your study also proved my understanding and i thank you very much for this.

We are waiting patiently...:-)

Hi Pollak,
We reproduced the issue. The issue is for this mp4 stream, parser fills two fields(Top and bottom) in the input buffer but decoder is consuming only first field and ignores second. This leads to decoder getting only TOP fileds and throws error 0x800000201 error.

We extracted h264 elementary stream from mp4 and then tried to decode. For this scenario parser fills only one field and proper decoding happens.

If I understand you correctly, the decoder does not know to treat correctly the interlaced video -am I correct?
If I understand correctly, it is not clear from your mail what should be the next step to solve the issue.
Thank you very much, but please, advice, what shall we do next...:-)

Hi Leon,

The ducatih264dec effectively supports interlaced video. I tested it with a sample video with the following characteristics taken out from mediainfo:

I used the following pipeline to decode and display the video:

# gst-launch-1.0 filesrc location= mm6-30-16FINAL.mp4 ! qtdemux name=demux de

After a analyze a little bit more the case with different sample videos I have (H264 enc, mp4 container, Scan type: progressive/interlaced/MBAFF), I conclude that the error is caused by incomplete or wrong metadata of the out.mp4 video. After analyzing different sample videos with mediainfo, all the videos that works fine with the ducatih264dec indicates the SCAN TYPE. In the case of the out.mp4 video it doesn´t indicates the SCAN TYPE, so I think maybe the cause of the error is around this.

I ran a pipeline that transcode the out.mp4 video on the AM5728 EVM. That pipeline decodes the video with avdec_h264, then encodes again with openh264enc and send it to a mp4 container. The I ran a pipeline to decode and display that trasncoded video, and it displays on the on-board LCD with no problems.

Transcode Pipeline:

# gst-launch-1.0 filesrc location= out.mp4 ! qtdemux ! h264parse ! avdec_h264
! queue ! openh264enc ! qtmux ! filesink location= transcode.mp4

Decode and play pipeline:

# gst-launch-1.0 filesrc location= transcode.mp4 ! qtdemux name=demux demux.vi
deo_0 ! queue ! h264parse ! ducatih264dec ! kmssink scale=false connector=30

One of the principal differences between the out.mp4 and transcode.mp4 is that out.mp4 doesn´t indicates the SCAN TYPE with media info. I will put below the mediainfo log for each video:

Hello,

I am able to play out.mp4 on EVM.

Could you try this pipeline:

root@am57xx-evm:/usr/share/ti/video# gst-launch-1.0 filesrc location=out.mp4 ! qtdemux ! h264parse ! 'video/x-h264, stream-format=byte-stream' ! h264parse ! ducatih264dec ! kmssink

Hello, Margarita.
Yes, the pipe with doubled h264parse works fine.
Please, can you be so kind to briefly explain what is the purpose of this duplication?
Thousands of thanks !!!

Hello, Daniel.
We carefully studied your recommendation about the "fiel" atom, which provides the information about the interlaced mode. It seems to be logic what you say. The only problem we have is that we were not able to find this atom in any one mp4 file we played successfully on the EVM. We still were trying to insert this atom into our mp4 file, when the post from Margarita came.
As I asked her, I do not understand what is the reason behind doubling the parser - which problem does it solve?
Is this somehow connected to the 'fiel' atom?
Thanks.

Hello Leon,

I am sorry for the delay.

We reproduced the issue with this pipeline gst-launch-1.0 filesrc location=out.h264 ! h264parse ! ducatih264dec ! kmssink.

I extracted the elementary stream from out.mp4 by using this:

gst-launch-1.0 filesrc location=out.mp4 ! qtdemux ! h264parse ! 'video/x-h264, stream-format=byte-stream' ! filesink location=test.h264

I played the elementary stream with :

gst-launch-1.0 filesrc location=test.h264 ! h264parse ! ducatih264dec ! kmssink

The issue was not observed when the elementary stream was played on the board.

So we assumed that the issue was with demuxer or parser, not the decoder.

In this case: gst-launch-1.0 filesrc location=out.h264 ! h264parse ! ducatih264dec ! kmssink

Demuxer/Parser is filling two fields in the input buffer but decoder consumes only one field and second is ignored(refer Ram Prasad's answer) .

Since I know in h264 streams there are a few different modes of encoding so sometimes you need to do a small conversion.

You could check h264parser element:

Capabilities:

video/x-h264

parsed: true

stream-format: { avc, avc3, byte-stream }

alignment: { au, nal }

After the h264parser's permutation (... h264parse ! 'video/x-h264, stream-format=byte-stream' ! h264parse ...) the second parser seems to sending only one field.
