Instead of returning EINVAL, which can cause a stream to fail to load, this allows the tag to be passed through to the flv demuxer, where it's summarily ignored. Signed-off-by:

If the selected coder isn't twoloop, this commit temporarily disables IS and PNS. The problem is in the encode_window_bands_info() being confused and setting invalid band_types for non-marked (normal) bands. Signed-off-by:

IS and PNS increase quality a ton so as a result the PSNR changed. Disable the extensions and keep the tests separate such that there will be no red herrings if one test fails. Signed-off-by:

Since the changes made a few week ago (which were done more than a month ago) the quality and stability of intensity stereo has been notably good. There were some requests and wishes to have in on by default and therefore it has been enabled. Should any regressions arise changes will be made to preferably keep it operating rather than just disabling it by default again. Signed-off-by:

It has been in the current encoder in its current implementation for quite some time now, so enable it by default. Will increase quality at all bitrates, especially at low ones. Signed-off-by:

Purely a cosmetic change, most of the zeroing of encoder resources should happen at the top of the main loop. Signed-off-by:

This commit reworks the TNS implementation to a hybrid between what the specifications say, what the decoder does and what's the best thing to do. The filter application function was copied from the decoder and modified such that it applies the inverse AR filter to the coefficients. The LPC coefficients themselves are fed into the same quantization expression that the specifications say should be used however further processing is not done, instead they're converted to the form that the decoder expects them to be in and are sent off to the compute_lpc_coeffs function exactly the way the decoder does. This function does all conversions and will return the exact coefficients that the decoder will generate, which are then applied to the coefficients. Having the exact same coefficients on both the encoder and decoder is a must since otherwise the entire sfb's over which the filter is applied will be attenuated. Despite this major rework, TNS might not work fine on some audio types at very low bitrates (e.g. sub 90kbps) as it can attenuate some coefficients too much. Users are advised to experiment with TNS at higher bitrates if they wish to use this tool or simply wait for the implementation to be improved. Signed-off-by:

Turns out autocorrelating more than 750 coefficients at once will cause a segfault, despite there being enough space to hold an entire frame of samples into the buffer. Signed-off-by:

This commit adds a function to get the reflection coefficients on floating point samples. It's functionally identical to ff_lpc_calc_ref_coefs() except it works on float samples and will return the global prediction gain. The Welch window implementation which is more optimized works only on int32_t samples so a slower generic expression was used. Signed-off-by:
