Apparently some A/V receivers do not behave well if "normal" DTS is passed through using the high bitrate spdif format normally used for DTS-HD (other receivers are fine with it). Parse the first packet passed to ad_spdif by decoding it with libavcodec in order to get the profile. Ignore the --ad-spdif-dtshd if it's not DTS-HD. (If the codec profile changes midstream, the user is out of luck. But this is probably an insignificant corner case.) I thought about parsing the bitstream, but let's not. While it probably wouldn't be that much effort, we are trying to keep it down on codec details here - otherwise we could just do our own spdif framing instead of using libavformat's spdif pseudo-muxer. Another possibility, using the codec parameters signalled by libavformat, is disregarded. Our builtin Matroska decoder doesn't do this, and also we do not want on the demuxer having to decode some packets in order to retrieve codec params (as libavformat does). Fixes #1949. |
