[MPlayer-dev-eng] [PATCH]SPDIF pass through decoder

[Naoya OYAMA]

Hi.

Thank you for your test resport.

ad_spdif.c has two problems.
The patch coping with a problem is attached.

[problem 1]
If demuxer specify -demuxer lavf,
MPlayer will judge that ad_spdif.c:init() went wrong.

Because bps and srate value were 0.
Native demuxers are automatically choosen,
bps and srate value were not 0.

[problem 2]
If demuxer specify -demuxer mpegps,
bellow line will failed.

lavf_ctx->oformat = av_guess_format(FILENAME_SPDIFENC, NULL, NULL);

Because av_register_all() was not executed.

Thank you.
