[FFmpeg-devel] [shan.wb at gmail.com: [libav-devel] Decoder for CEA-608 and World System Teletext]

Hi Shan, I'm forwarding this to the appropriate mailing list and adding
Anshul in CC.

Am I interpreting your mail correctly if I say you do not plan to
contribute yourself to the project?

Subject: [libav-devel] Decoder for CEA-608 and World System Teletext

Just a FYI,

I noticed the recent, but limited CEA-608 decoder addition to the ffmpeg
project.  I have developed my own version to translate these to 25
frame STL files a while ago in my own time for the broadcaster I work
for. I would have submitted them, but I loath using git for any thing
but basic retrival.  My code has a lower memory footprint, has full
char support with ASS styling, with built-in MXF VANC and DVB support.
I've put it up on my google site at
http://sites.google.com/site/xhelmboyx/code.

So if any one wants to include it can go ahead.

PS, for MXF you may need to add these lines to the demuxer:

static const MXFCodecUL mxf_data_essence_container_uls[] = {
// data essence container uls
{ { 0x06,0x0E,0x2B,0x34,0x04,0x01,0x01,0x09,0x0D,0x01,0x03,0x01,0x02,0x0D,0x00,0x00 },
14,   AV_CODEC_ID_NONE },    /* Generic VBI Data */
{ { 0x06,0x0E,0x2B,0x34,0x04,0x01,0x01,0x09,0x0D,0x01,0x03,0x01,0x02,0x0E,0x00,0x00 },
14,   AV_CODEC_ID_MXF_VANC }, /* Generic ANC Data */
{ { 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00 },
0,      AV_CODEC_ID_NONE },
};

{ { 0x06,0x0E,0x2B,0x34,0x02,0x53,0x01,0x01,0x0d,0x01,0x01,0x01,0x01,0x01,0x5C,0x00 },
mxf_read_generic_descriptor, sizeof(MXFDescriptor), Descriptor }, /*
VANC */

PPS, I not on this mailing list either.
