bool KinoMJPEGVideoPipe::CloseVideo (   )  [virtual]

Close the video pipe. Implements KinoVideoPipe. Definition at line 648 of file kino_av_pipe.cc. References frame, output, sigpipe_clear(), and sigpipe_get(). { sigpipe_clear(); pclose( output ); delete[] frame[ 0 ]; delete[] frame[ 1 ]; delete[] frame[ 2 ]; return sigpipe_get() == 0; }

bool KinoMJPEGVideoPipe::OpenVideoPipe (  char *  pipe, int  width, int  height, bool  interlaced = true )  [virtual]

Open the video pipe. Implements KinoVideoPipe. Definition at line 606 of file kino_av_pipe.cc. References frame, output, pitches, sigpipe_clear(), and sigpipe_get(). { sigpipe_clear(); output = popen( pipe, "w" ); this->width = width; this->height = height; pitches[ 0 ] = width * 2; pitches[ 1 ] = 0; pitches[ 2 ] = 0; frame[ 0 ] = new uint8_t[ width * height ]; frame[ 1 ] = new uint8_t[ width * height / 4 ]; frame[ 2 ] = new uint8_t[ width * height / 4 ]; int written = 0; if ( output != NULL ) written = fprintf( output, "YUV4MPEG2 W%d H%d F%s %s\n", width, height, height == 576 ?

bool KinoMJPEGVideoPipe::OutputVideoFrame (  uint8_t *  frame, int  size )  [virtual]

Output a video frame - the input is assumed to be YUV422 and output is YUV420P. Implements KinoVideoPipe. Reimplemented in KinoDeinterlacedMJPEGVideoPipe.
