Still be less verbose about channel count change from 0 channels.

Only inform the user that the number of channels changed if it was set
before.

The dca parser needs to check that the framesize is actually of a complete
frame, and not of a partial DTS-HD frame, which is not constant size, and
thus the check would fail.

Prevent error condition in case sample_rate is unset or set to a negative
value. In particular, fix divide-by-zero error occurring in ffmpeg due to
sample_rate set to 0 in output_packet(), in code:

                ist->next_pts += ((int64_t)AV_TIME_BASE * ist->st->codec->frame_size) /
                    ist->st->codec->sample_rate;

Fix trac ticket #324.

they wont conflict when they get added to the fork with randomly changed order and values.
Also add duplicate codec_ids to allow maintaining compatibility.
