* avcodec/d3d12va_encode: use correct none flagKacper Michajłow10 days1-1/+1
| | | | | | NFC, it's still 0, but correct enum type so compilers won't complain. Signed-off-by: Kacper Michajłow <kasper93@gmail.com>

* avcodec/jpegxl_parser: add sanity check for frame sizeLeo Izen12 days1-1/+8
| | | | | | | | | | If a frame size is absolutely massive, this can spin the parser as it attempts to decode a permuted TOC. We add a sanity check here for eight times the size of the image for an internal frame to prevent malicious bitstreams from slowing the parser down to a crawl.

* avcodec/ffv1dec: Check k in get_vlc_symbol()Michael Niedermayer2025-07-201-0/+5
| | | | | | | | | | | | The true problem happens in several previous get_vlc_symbol() but checking that is more expensive (involving FFABS()) here its just a simple check between 2 variables we have.

* 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.

* libavcodec/alsdec.c: Add check for av_malloc_array() and av_calloc()Jiasheng Jiang2025-07-121-2/+6
| | | | | | | | | Add check for the return value of av_malloc_array() and av_calloc() to avoid potential NULL pointer dereference.

* avcodec/mpegvideo_dec: Avoid implicit NULL + offsetAndreas Rheinhardt2025-07-112-32/+33
| | | | | | | | | Happens since 4fc874ef0813d39983f9b634cec42798aa94b57a when this code is called via error resilience. Also do the same for wmv2dec.c. Fixes the vsynth_{1,2,3,_lena}-mpeg4-error and wmv2-drm-dec FATE-tests. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/opus/dec: Remove unused parametersAndreas Rheinhardt2025-07-111-5/+2
| | | | | | | | The parameters here are not only unused, but buf_size's value is actually wrong when flushing (it comes from the subpacket of the last packet sent and is therefore outdated). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/get_bits: Remove GetBitContext.buffer_endAndreas Rheinhardt2025-07-111-5/+1
| | | | | | | | | | | It is unused. Furthermore, this automatically fixes the issue that init_get_bits() failure would lead to NULL + 0 (when setting buffer_end) which is UB before C23. This happened in the fic-avi and fic-avi-skip_cursor FATE-tests. This saved 7296B of .text here. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
