CDVDVideoCodecC1: Failed to open C1 Amlogic Codec

[SamuelBrucksch]

I always get the error that it failed to open the codec. I use an odroid c1+ and i tried the aml-libs that are delivered from odroid as debian package and i compiled it myself from here: https://github.com/mdrjr/c1_aml_libs

Tried running as root as well but didnt make a difference. Can you help me setting up the codec correctly so that this works?

Thanks!!

[Owersun]

Hello, do you use the c1_aml branch? The master branch is for Samsung Exynos chips, it uses different process.

[SamuelBrucksch]

Yes i use the c1 aml branch... What i do is i either use the deb or the driver from github and compile it. No error occur. Then i adjust rights in /usr/include/am* and /usr/lib/aml_libs so it is readable and then i compile your mymfc in c1_aml branch. But it keeps saying that it cannot load the codec.

How did you install the codec? Did you do any additional steps? And are you using the c1 as well? I use the default ubuntu image from hardkernel.

[Owersun]

Yes, that's mostly everything you need to do. I did test it on C1 as well. Can you paste couple of lines that are printed before the final message, as well as 10 last lines from dmesg after you try to run the program.

I use this video: http://download.openbricks.org/sample/H264/big_buck_bunny_1080p_H264_AAC_25fps_7200K.MP4

BTW that CBitstreamConverter::Open avcC data too small or missing does not come with a mpeg1 or 2 testfile, but the result is the same. It says cannot find codec...

[Owersun]

I'll give it a look this evening, but right now it looks like there is no codec initialized in the kernel for you, since dmesg doesn't change. There should be at least some messages about something happening to the codec. Can you install a Kodi for C1 and try to play any video, look at what logs would say, are they player using the codec or ffmpeg?

And in KODI see attached screenshot.

[Owersun]

Yeah, this one is right, meaning the codec is present in the system. I'll take a look into what could be wrong with the console program this evening, in 8-9 hours.

[SamuelBrucksch]

Cool. Thanks for your help.

[SamuelBrucksch]

BTW i just found out, that false is returned at this point: https://github.com/Owersun/mymfc/blob/c1_aml/LinuxC1Codec.cpp#L534

width or height is zero... Maybe that helps identifying the issue.

I just added additional output in main.c: Main::main - Header of size 138848, width: 0, height: 1920

Even when i use different video sizes width is always zero but height works...

[Owersun]

Yeah, this is the issue, for some reason the size of the video is reported to have 0 as one dimensions. It will not work to just comment out the check, since the screen size is set base on that after as well. Can you maybe update your ffmpeg libraries? Becuase to parse the video the ffmpeg is used and the program totally relays on what the ffmpeg gives as video properties to it.

This is what i get. Its the systems default ffmpeg. Which version do you use?

[Owersun]

I compile my own from their git master branch most of the time, since I deal with that features a lot. Can you do ffprobe on the file you are trying to play and see what is going to be the output?

[Owersun]

Well this looks fine, still hints are coming from here: https://github.com/Owersun/mymfc/blob/c1_aml/main.cpp#L90 and codecCtx is AVCodecContext type, which is purely ffmpeg internal stuff... So I cannot tell much where width and height becoming 0 and why. Maybe you can add a debug right after these assignment too see what you are getting from ffmpeg?

[SamuelBrucksch]

Will update ffmpeg first and see what happens then.

[SamuelBrucksch]

Ok new FFMPEG version detects width & height correctly: CDVDVideoCodecC1::Open Opened C1 Amlogic Codec. DisplayWidth: 1920, DisplayHeight: 1080

But now i get errors like this: CLinuxC1Codec::Decode CLinuxC1Codec::get_pts_video get_pts_video: 0 CLinuxC1Codec::Decode rtn(2), m_cur_pictcnt(0), m_cur_pts(0.000000), lastpts(0.000000) Main::main - Extracted frame number 285 of size 1 CBitstreamConverter::Convert: error converting.

Video is not displayed at all...

[Owersun]

Bitstream converter is something mapping the data in each frame h264 bitstream to annexb bitstream. The frame size of 1 byte look very suspicious, and very probably error on conversion could happen. And again, the CBitstreamConverter that does that I took as the whole block from Kodi codebase, didn't modify a bit in it. So it's even the ffmpeg is again preparing corrupt data for the input, or bitstream converter from Kodi cannot deal with the data coming from ffmpeg... Did you prepare in any way the video you are trying to play, or is it the normal .avi/.mkv file?

[SamuelBrucksch]

It is a normal mp4 h264 test video. Worked on all other systems where i tested with hardware acceleration and in kodi it worked as well... guess i have to look for changes in kodi and update your classes... Will report back if i get it to work.
