* af_hdcd: disable auto-convert by defaultBurt P2016-10-05
| | | | | | | | | | As all known valid HDCD sample formats and sample rates are now handled by the filter, remove the scan that "invades the privacy" of the filter graph and turn off autoconvert by default as requested by Nicolas George. http://ffmpeg.org/pipermail/ffmpeg-devel/2016-August/197571.html Signed-off-by: Burt P <pburt0@gmail.com>
* af_hdcd: add experimental 20 and 24-bit decoding supportBurt P2016-10-05
| | | | | | | | | | I don't have any legitimate 20 or 24-bit HDCD to test. It is known that the PM Model Two would insert packets into 20 and 24-bit output, but I have no idea what differences in behavior existed when decoding 20 or 24-bit. For now, as with 16-bit, PE (if enabled) will expand the top 3dB into 9dB and LLE (gain adjust) will be applied if signaled. Signed-off-by: Burt P <pburt0@gmail.com>
* af_hdcd: hdcd_scan() and hdcd_integrate() handle stereo and single channelBurt P2016-10-05
| | | | | | | | | | | New versions of hdcd_scan() and hdcd_integrate() that also do the work of hdcd_scan_stereo() and hdcd_integrate_stereo(). Some code split into previously separate functions to remove duplication is now merged back into each function in the single place where it is used. Signed-off-by: Burt P <pburt0@gmail.com>
* af_hdcd: support s16p (WavPack) directlyBurt P2016-10-05
| | | | | | | The buffer is already being copied anyway, so interlace the planar format during the copy and remove one use of auto-convert. Signed-off-by: Burt P <pburt0@gmail.com>
* af_hdcd: allow all HDCD sample ratesBurt P2016-10-05

* af_hdcd: for easier maintenance alongside libhdcdBurt P2016-08-25
| | | | | | | | | | | | | | Mostly just re-arranges some code to make it easier to update this filter and libhdcd together. filter_frame() is much simpler as a result. * use the HDCD detection data structure and functions from libhdcd, moved detection code out of filter_frame() * moved analyze_mode preparation out of filter_frame() into hdcd_analyze_prepare(), from libhdcd * moved some macro definitions to the top so they are all together Signed-off-by: Burt P <pburt0@gmail.com>

| | | | | | | | | | A new mode, selected by filter option, to aid in analysis of HDCD encoded audio. In this mode the audio is replaced by a solid tone and the amplitude is adjusted to signal some specified aspect of the process. The output file can be loaded in an audio editor alongside the original, where the user can see where different features or states are present. Signed-off-by: Burt P <pburt0@gmail.com>

* af_hdcd: Process stereo channels together, fix #5727Burt P2016-08-01
| | | | | | | | | | | | | | | Issue #5727: gain adjustment should only be applied if matching gain value from a valid packet in both channels. The existing functions process each channel separately, so it was not possible. * New versions of hdcd_process(), hdcd_scan(), hdcd_integrate() named hdcd_*_stereo() that process both channels together. * target_gain applied will be the last matching target_gain. * The old single channel functions remain as an option. They can be used by: -af hdcd=process_stereo=0. Signed-off-by: Burt P <pburt0@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
