There were some errors in the calculation as well as an entire unnecessary loop to find the gain coefficient. Merge the two loops. Thanks to @ubitux for the suggestions and testing.

Having it as a float didn't even allow enough precision to check for INT_MAX/2. Signed-off-by:

av_warn_unused_result is added to functions whose return status should be checked. Currently does not trigger any warnings, but should be useful for future robustness. Reviewed-by:

The fate test command line is supposed to serve as an example. It's nicer to explicitly state the profile rather than setting options to force it for you.

Fails on some newer systems (archlinux with a modern GCC version).

Since it became the default option, in order to prevent interference with the other tests, disable it.

In light of the recent changes to the TNS system, it has been deemed worthy and robust enough to be turned on by default.

Changes: - strongly prefer dual filters to a single filter - less strict about using 2 filters w.r.t. energy - scrap the usage of threshold and spread, useless - use odd-shaped windows to set the filter direction - use 4 bits instead of 3 bits for short windows - simplify and reduce the main loop to a single level - add stricter regulations for short windows All of this now makes the TNS implementation operate as good as it can and it definitely shows. The frequency thresholds are now even better defined by looking at the spectrals and the overall sound has been improved at the price of just a few bits that are well worth it.

It's simpler and has 2 less levels than the previous which was practically lifted from the decoder with put_bits() instead of get_bits().
-
Rostislav Pehlivanov authored
Too much effort and work has been spent on such a simple function. It simply refuses to work as the specifications say, the transformation is NOT lossless and creates some crackling and distortions. Therefore disable it by default and add a couple of warnings to scare people away from touching it or wasting their time the way I did.
-
Rostislav Pehlivanov authored
The decoder does this so I guess we better do that as well. There's barely any difference between the autoregressive and the moving average filters looking at spectrals though.

Silences warnings regarding `clCreateCommandQueue` being deprecated. Only a very limited number of products support 2.0. Since the replacement API (`clCreateCommandQueueWithProperties`) is only available in 2.0, we should not update it just yet.

GCC 3.4 miscompiles it on sunos. Date of release? The second of August two thousand and five, anno Domini. That's ten years two months and fourteen days ago. Three thousand seven hundred and twenty seven days ago. One sixth of the average life expectancy of a person living in a country with a human development index of zero point eight hundred and eight, equality adjusted. GCC 4.3 also miscompiles it, though not as bad.

The LTP encoding and the test is a bit slow currently, taking twice the amount of time the other tests do, so in the future the total time to encode might be cut down on that test.
-
Rostislav Pehlivanov authored
It didn't work out because of the exceptions that needed to be made for the "-1" cases and was overall more confusing that just manually checking and setting options for each profile.

Commit bf0d2d60 introduced av_warn_unused_result to avfilter/formats, whose associated warnings were mostly fixed in 6aaac24d. This fixes the issues in avfilter/avfiltergraph. Tested with FATE. Reviewed-by:

Long Term Prediction allows for prediction of spectral coefficients via the previously decoded time-dependent samples. This feature works well with harmonic content 2 or more frames long, like speech, human or non-human, piano music or any constant tones at very low bitrates. It should be noted that the current coder is highly efficient and the rate control system is unable to encode files at extremely low bitrates (less than 14kbps seems to be impossible) so this extension isn't capable of optimum operation. Dramatic difference is observable with some types of audio and speech but for the most part the audiable differences are subtle. The spectrum looks better however so the encoder is able to harvest the additional bits that this feature provies, should the user choose to enable it. So it's best to enable this feature only if encoding at the absolutely lowest bitrate that the encoder is capable of.

Apparently it was set to be enabled by default but after the profile commits it was reverted to be off by default because I didn't notice. Works well so (re)enable it.

Needed because LTP uses predictor_present as well.

An oversight, probably because of copy-pasting the TNS line.

Functionally identical, doesn't change anything.
