<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>Hi dear community,<br>
I have a problem with the encoding using x264. After I call x264_encoder_encode(
h, &nal, &i_nal, pic, &pic_out) function I have nal= NULL,
i_nal=0 and the function return 0. I'm sure that pic contain the correct image.
The x264_t h is open using the default parameters, i only change width and
length of the video. The function don't give me any error, it seems that it not
encode any data. I include the code of encoding function that I implement
watching x264.c.<br>
<br>
void MyFunction()<br>
{<br>
x264_param_t param;<br>
x264_t *h;<br>
x264_picture_t pic;<br>
<br>
//Set the default parameters<br>
x264_param_default( &param );<br>
<br>
//Video settings<br>
param->i_width = WIDTH;<br>
param->i_height = HEIGHT;<br>
<br>
//Open the encoder<br>
if( ( h = x264_encoder_open( &param ) ) == NULL )<br>
{<br>
fprintf( stderr, "x264
[error]: x264_encoder_open failed\n" );<br>
return -1;<br>
}<br>
<br>
/* Create a new pic */<br>
x264_picture_alloc( &pic, X264_CSP_I420, param.i_width,
param.i_height );<br>
<br>
//Launch the encode routine <br>
Encode_frame( h , &pic );<br>
<br>
//Release resoirce<br>
x264_picture_clean( &pic );<br>
x264_encoder_close(h);<br>
}<br>
<br>
int Encode_frame( x264_t *h , x264_picture_t *pic)<br>
{<br>
x264_nal_t *nal;<br>
int i_nal, i;<br>
x264_picture_t pic_out;<br>
static int mux_buffer_size = 0;<br>
uint8_t *mux_buffer = NULL;<br>
int size;<br>
<br>
//Set YUV420<br>
pic->img.i_csp = X264_CSP_I420;<br>
pic->img.i_plane = 3;<br>
<br>
//I take the YUV image from a
decoded image decode with ffmpeg<br>
if (picture) {<br>
for(i = 0; i <
3; i++){<br>
pic->img.plane[i] = picture->data[i];<br>
pic->img.i_stride[i] = picture->linesize[i];<br>
}<br>
<br>
pic->i_pts =
picture->pts;<br>
pic->i_type =
X264_TYPE_AUTO;<br>
}<br>
<br>
//pic contains the correct image. <br>
if( (i = x264_encoder_encode( h,
&nal, &i_nal, pic, &pic_out)) <0)<br>
return
-1; <br>
<br>
/*<br>
* In this point nal is
null, i_nal is 0. There isn't any error message in the routine.<br>
* As consequence the
next loop don't execute any step.<br>
*/ <br>
<br>
<br>
//packetize the encoded information
in nal unit<br>
for( i = 0; i < i_nal; i++ )<br>
{<br>
int i_size;<br>
<br>
printf("\nNal unit n° %d",i);<br>
<br>
if(
mux_buffer_size < nal[i].i_payload * 3/2 + 4 )<br>
{<br>
mux_buffer_size = nal[i].i_payload * 2 +
4;<br>
free( (void*) mux_buffer );<br>
mux_buffer = (uint8_t*) malloc(
mux_buffer_size );<br>
}<br>
<br>
size = size +
mux_buffer_size;<br>
i_size =
mux_buffer_size;<br>
x264_nal_encode(
mux_buffer, &i_size, 1, &nal[i] );<br>
write_nal_unit(
mux_buffer , i_size ,"outframe.mpeg4" );<br>
}<br>
<br>
return size;<br>
}<br>
<br>
I'm excuse in advance. I'm not sure that is the correct mailing list (if not is
very appreciated if suggest me what mailing list is the right).<br>
Many thanks. <o:p></o:p></span></font></p>
