MPEG1 Encoder Example

janlund1967 — Mon, 10 Jul 2006 22:44:08 GMT

Hi.

Doessomeone have a MPEG1 encoder example in its simplest form?

(ie. no dectection of anything, hardcoded framesize, hardcoded frame rate etc)

Basically, i want to stuff a series of Ipp8u* 's (coming from a framegrabber) into a MPEG-1 file.

Something like this (pseudo C - i am a Delphi programmer :o) :

MyMP1Encoder->Init("C:Test.mpg");

For (x=0; x

{ MyMP1Encoder->AddFrame(MyNewFrame); }

MyMP1Encoder->DeInit;

Howshould i implement the Init, AddFrame and DeInit methods ?

Thanks

Jan

Hi, why do you need in MPEG1? Probably you can also use MPEG2? If so, please take a look on IPP media sample, which contains video_ec_con application to demonstrate how to implement MPEG encoders with IPP and UMC

There is also comments from our MPEG expert

First, we dont support mpeg1 encoding, but do mpeg2. There is no significant difference.

To do encoding a simplest way it is needed to create an encoder object MPEG2VideoEncoder, then create VideoEncoderParams, set there width, height, frame and bit rate.

Then call encoder->Init(params).

After that create VideoData for input and MediaData for output. Than in loop read uncompressed YUV video to VideoData, call encoder->GetFrame, and store MediaData.

Deletre created objects. That is all.

umc_video_enc_con can be used as an example and for more information. Documentation to UMC and components is available as well.
