| | | | | | | | | | | | | | | | | | | | Pulses are already on the way so expect to see the list gone in the close future. TNS is already of sufficiently high quality to be enabled by default (but isn't yet, so you too can help by testing!). Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* | aacenc_tns: rework the way coefficients are calculatedRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit abandons the way the specifications state to quantize the coefficients, makes use of the new LPC float functions and is much better. The original way of converting non-normalized float samples to int32_t which out LPC system expects was wrong and it was wrong to assume the coefficients that are generated are also valid. It was essentially a full garbage-in, garbage-out system and it definitely shows when looking at spectrals and listening. The high frequencies were very overattenuated. The new LPC function performs the analysis directly. The specifications state to quantize the coefficients into four bit index values using an asin() function which of course had to have ugly ternary operators because the function turns negative if the coefficients are negative which when encoding causes invalid bitstream to get generated. This deviates from this by using the direct TNS tables, which are fairly small since you only have 4 bits at most for index values. The LPC values are directly quantized against the tables and are then used to perform filtering after the requantization, which simply fetches the array values. The end result is that TNS works much better now and doesn't attenuate anything but the actual signal, e.g. TNS removes quantization errors and does it's job correctly now. It might be enabled by default soon since it doesn't hurt and helps reduce nastyness at low bitrates. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* | aac: remove now-unused redundant arrayRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | | | | | This commit removes the array which was made redundant with the last commit. The current prediction system gets the quantization error directly (and without the single-frame delay) in the search_for_pred function. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* | aacenc_pred: rework the way prediction is doneRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit completely alters the algorithm of prediction. The original commit which introduced prediction was completely incorrect to even remotely care about what the actual coefficients contain or whether any options were enabled. Not my actual fault. This commit treats prediction the way the decoder does and expects to do: like lossy encryption. Everything related to prediction now happens at the very end but just before quantization and encoding of coefficients. On the decoder side, prediction happens before anything has had a chance to even access the coefficients. Also the original implementation had problems because it actually touched the band_type of special bands which already had their scalefactor indices marked and it's a wonder the asserion wasn't triggered when transmitting those. Overall, this now drastically increases audio quality and you should think about enabling it if you don't plan on playing anything encoded on really old low power ultra-embedded devices since they might not support decoding of prediction or AAC-Main. Though the specifications were written ages ago and as times change so do the FLOPS. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* | aacenc: change FF_PROFILE_UNKNOWN to AAC-Main if prediction is enabledRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | This was missed when the original commits were done. FF_PROFILE_UNKNOWN is what's in avctx->profile when no audio profile is specified. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>
* | lpc: create a simplified Levinson-Durbin LPC handling float samplesRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit simply duplicates the functionality of ff_lpc_calc_coefs() for the case of a Levinson-Durbin LPC with the only difference being that floating point samples are accepted and the resulting coefficients are raw and unquantized. The motivation behind doing this is the fact that the AAC encoder requires LPC in TNS and LTP and converting non-normalized floating point coefficients to int32_t using SWR and again back for the LPC coefficients was very impractical. The current LPC interfaces were designed for int32_t in mind possibly because FLAC and ALAC use this type for most internal operations. The mathematics in case of floats remains of course identical.

* | aac: move the TNS tables from aacdectab to the shared aactabRostislav Pehlivanov2015-08-29
| | | | | | | | | | | | | | | | | | | | | | | | This commit simply moves the TNS tables to a more appropriate aactab.h since then they can be accessed by both the decoder and encoder. The encoder _shouldn't_ normally need the tables since the specs describe a specific quantization process, but the exact reason for this can be seen in the TNS commit following.

* | avcodec/vc1dec: Re-order init to avoid initting hwaccel too earlyPhilip Langdale2015-08-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At least for vdpau, the hwaccel init code tries to check the video profile and ensure that there is a matching vdpau profile available. If it can't find a match, it will fail to initialise. In the case of wmv3/vc1, I observed initialisation to fail all the time. It turns out that this is due to the hwaccel being initialised very early in the codec init, before the profile has been extracted and set. Conceptually, it's a simple fix to reorder the init code, but it gets messy really fast because ff_get_format(), which is what implicitly trigger hwaccel init, is called multiple times through various shared init calls from h263, etc. It's incredibly hard to prove to my own satisfaction that it's safe to move the vc1 specific init code ahead of this generic code, but all the vc1 fate tests pass, and I've visually inspected a couple of samples and things seem correct.
