* avformat/flvdec: don't skip backwards or over EOFTimo Rothenpieler2025-07-161-2/+10
| | | | | | | | | | | Skipping backwards (and even forwards) resets the EOF flag, and can thus lead to infinite looping if the conditions are just right.

* avutil/hwcontext_vulkan: don't over-map buffers with prior paddingNiklas Haas2025-07-151-1/+2
| | | | | | | | | | | | | If the image data is not at the start of the buffer allocation, such as when the buffer has padding before the image data, this function maps too much memory, since src_data + src_buf->size exceeds the buffer size. Fix this by subtracting the difference between the buffer start and the provided image data pointer from the size of the memory range to map. An easy way to reproduce this issue is using the vf_pad filter, which allocates image data buffers with a nonzero offset whenever padding is requested before the start of the image data.
* aacenc_tns: clamp filter direction energy measurementLynne2025-07-151-9/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The issue is that: float en[2]; ... tns->n_filt[w] = is8 ? 1 : order != TNS_MAX_ORDER ? 2 : 3; for (g = 0; g < tns->n_filt[w]; g++) { tns->direction[w][g] = slant != 2 ? slant : en[g] < en[!g]; When using the AAC Main profile, n_filt = 3, and slant is by default 2 (normal long frames), g can go above 1. en is the evolution of energy in the frequency domain for every band at the given window. E.g. whether the energy is concentrated at the top of each band, or the bottom. For 2-pole filters, its straightforward. For 3-pole filters, we need more than 2 measurements. This commit properly implements support for 3-pole filters, by measuring the band energy across three areas. Do note that even xHE-AAC caps n_filt to 2, and only AAC Main allows n_filt == 3.

As of writing, this generates the following format list: - gbrap - gbrap10le - gbrap12le - gbrap14le - gbrap16le - gbrp - gbrp10le - gbrp12le - gbrp14le - gbrp16le - gbrp9le - gray - gray10le - gray12le - gray14le - gray16le - gray9le - ya16le - ya8 - yuv410p - yuv411p - yuv420p - yuv420p10le - yuv420p12le - yuv420p14le - yuv420p16le - yuv420p9le - yuv422p - yuv422p10le - yuv422p12le - yuv422p14le - yuv422p16le - yuv422p9le - yuv440p - yuv440p10le - yuv440p12le - yuv444p - yuv444p10le - yuv444p12le - yuv444p14le - yuv444p16le - yuv444p9le - yuva420p - yuva420p10le - yuva420p16le - yuva420p9le - yuva422p - yuva422p10le - yuva422p12le - yuva422p16le - yuva422p9le - yuva444p - yuva444p10le - yuva444p12le - yuva444p16le - yuva444p9le - yuvj411p - yuvj420p - yuvj422p - yuvj440p - yuvj444p
* avfilter/vf_thumbnail: support more planar formatsNiklas Haas2025-07-121-5/+20
| | | | | | | | | | | This adds support for high bit depth formats, as well as formats with fewer than 3 planes. The implementation for HBD is the same as for 8 bit formats, just right shifted to 8 bits. It's worth pointing out that this also works for HDR formats (and even DV), because the underlying implementation is just trying to minimize the histogram difference. If anything, using a HDR format will result in a *more* accurate detection, because HDR formats tend to be more perceptually uniform.
