Mpeg4 and H264 playback

Manuel Guerrero

I have a DM365 design and I am using the DVSDK_2_10_01_18 and the Montavista tools V5. My host runs Red Hat Linux 4.

I have been having problems playing mpeg4 and h264 files. These are the davinci_effect.mpeg4 and h264 demo data files respectively that come with the DVSDK. When I start playing them I get the message "failed to decode video buffer data". Curiously it will play files I created with a DM355 EVM a while back. I have also tried using ffmpeg and adding the VOL header with no success. I didn't think it would work since I can't even play the demo files included in the DVSDK.

I know and have confirmed that in the Rules.mak I have the PLATFORM=dm365 definition set correctly . I can build the DVSDK successfully. One thing I have noticed is that the codec_engine_2_24 is not part of the build from the top level directory. If I cd to where the Makefile is and start a make it complains that it's missing dm355 directories. This is probably correct since I am building for a dm365. I do make use of the mp4dec.a library that is included in this directory to satisfy the calls from the algorithm tables I have included at the end of this email.

My code successfully opens the codec engine and the decoder as in Engine_open() and Vdec2_create(), Videc_setBufTab(). The Loader is being created with the proper attributes and buffer sizes by calling Vdec2_getInBufSize() and then opening the loader. All of this is confirmed by the fact that the MPEG4 files created with a DM355 play. I have various MPEG4 files of different view and length sizes. From full 726x576 to 320x240 , etc.

The problem occurs during priming when I call Vdec2_process() which returns a -1 and prints on the console failure deciding buffer data.

The fact that it plays old DM355 files seems to point to some configuration problem with the codecs, but everything I seem to look for is correctly set up. I would appreciate if you could give me some clue or if you want me to capture more data or give you any other information.

Thank you in advance for any help

Hi,

Can you send us the error code which you are getting from the process call ? You say that you see this behaviois for both Mpeg4 and H.264, pls send the error codes for both the codecs. Trace log with CE_DEBUG = 3 will also be helpful.

regards

Any ideas anybody?

Manuel,

Please remember that the dm365 mpeg4 is not a universal decoder, and will not be able to decode all mpeg4 streams.

The dm365 mpeg4_hdvicp decoder is universal and will be able to decode all mpeg4 streams.

I have seen the behavior you describe when I tried to decode some mpeg4 streams with the mpeg4 decoder. The problem was solved when I used the mpeg4_hdvicp decoder

Thanks

How do I use that codec?

The Engine_AlgDesc engineAlgs0 that I show earlier in the post describes the actual algorithm used

Do I have to do anything special when building the DVSDK?

Thanks for your help

Hi,

You can download universal Mpeg 4 decoder from below. MPEG4 Decoder, Version 2.00.00.05

http://software-dl.ti.com/dsps/dsps_public_sw/codecs/DM365/index_FDS.html

The integration guide of that codec in DSVDK 2.1 is below.

I installed all the files and recompiled the DVSDK with no errors. When I try to run the decode application I get the errors shown below

I use the loadmodules_hd.sh that comes with the DVSDK as follows
