Endode - Fourcc codec

Most PC based video players support multiple FOURCC codes for any codec. If the one your are using works for you, then better stick to it since support is typically player dependent.

You have not specified which codec you are using. Common usage is as follows:
For H.264 you can use H264, AVC1.
For MPEG4 you can use FMP4, M4CC, MP4V
For H.263 you can use H263.

Oks, thank you.

When I chose a bad FOURCC appeared a lot of visual artifacts. Now, I've chosen one of these FOURCC and only appeared a few visual artifacts.

Is this a known issue? Are there any solution to remove them?

I use next configuration. If I change "rateControlPresent" and "maxBitRate" the result is the same: a few visual artifacs.

I send you a mpeg video, where appear visual artifacs at frames 6,7,8, 33,34,35 and 37.

The visual artifacts always appear at the bottom of the image.

I thank you your help.

//Configuration

    //Static Parameters

    //Dynamic Parameters

m_DynamicParams.mbDataFlag = 0;

Hi santipami,

I have checked the bit stream; it could be the issue with respect to padding or saturation.

Can you try setting qpmin to 8, this is an extended dynamic parameter.

Please share the algorithm release version number getting used?

Also share the input YUV sequence

Regards

sangita

The algorithm release version number is 2.00.004.

In the extended dynamic parameters there isn't any "qpmin" parameter. Did you refer qpIntra or qpInter?

I'm sending you a mpeg video and its related yuv video today.

Thanks.

This is the avi File (width 638, height 478). There are artifacs in the following frames:

From 13 to 16
From 23 to 29

Thanks.

This is the mpeg stream.

This is the yuv file.

Warning! I've canged the ".yuv" fil extenstion to ".zip" file extension because I couldn't upload it. Please. change ".zip" to ".yuv".

Hi santipami,

Thanks for sharing the details. I have verified the issue is re-producible with 2.00.004 version. However 2.00.004 is quite old release, done in 2009.

 Please try using 02.03.00.00 algorithm version released in April 2010. This has a bug fix for non multiple of 16 resolution sequences. Issue is fixed in this version of algorithm release.

Sangita

Where could I find this codec?

I searched in "TI Home > Digital Signal Processors & ARM Microprocessors > Get Support > Find Software & Tools - Overview > Algorithms/Codecs"

I work with DM6446, so I searched codecs in "http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C64XPlus_Video/index_FDS.html".

I didn't found 02.03 version. The lasted version is "MPEG4 Encoder, Version 2.02.04.00".

Thanks
