Tool/software: Linux
i'm trying to get the encode and decode example together. i start my work based on encode example.(D-M-3-6-8.) and i can run these examples seperately.
i think there are many things i hava to do.
first of all ,the encode example :codec.c and encode.cfg engine do not have decoder ,so i have to add it.
second,i have to add the decode process .
but in the first step.
codec.c
static Codec videoDecoders[] = {
{
"mpeg4dec",
"MPEG4 SP Video",
mpeg4Extensions,
NULL,
NULL
},
{
"h264dec",
"H.264 HP Video",
h264Extensions,
&H264_PARAMS,
NULL
},
{
"mpeg2dec",
"MPEG2 Video",
mpeg2Extensions,
NULL,
NULL
},
{ NULL }
};
/* NULL terminated list of video encoders in the engine to use in the demo */
static Codec videoEncoders[] = {
{
"mpeg4enc",
"MPEG4 Video",
mpeg4Extensions,
NULL,
NULL
},
{
"h264enc",
"H.264 HP",
h264Extensions,
NULL,
NULL
},
{
"mpeg2enc",
"MPEG2",
mpeg2Extensions,
NULL,
NULL
},
{ NULL }
};
/* Declaration of the production engine and encoders shipped with the DVSDK */
static Engine encodeEngine = {
"encode", /* Engine string name used by CE to find the engine */
NULL, /* NULL terminated list of speech decoders in engine */
NULL, /* NULL terminated list of audio decoders in engine */
videoDecoders, /* NULL terminated list of video decoders in engine */
speechEncoders, /* NULL terminated list of speech encoders in engine */
audioEncoders, /* NULL terminated list of audio encoders in engine */
videoEncoders /* NULL terminated list of video encoders in engine */
};
/*
* This assignment selects which engine will be used by the demo. Note that
* this file can contain several engine declarations, but this declaration
* determines which one to use.
*/
Engine *engine = &encodeEngine;

when i create myEngine,only the h264dec can't be added.when it was added .the encode example have problems and can run correctly.
the message is as follows:

i need help very much. i consider memory if not enough,but other decoders and encoders all can be added except the h264dec.do anyone have any sugesstions for me ? thank you verymuch.
