avcodec/jpegxl_parser : add some icc profile checks
3 octobre 2023, par Leo Izenavcodec/jpegxl_parser : add some icc profile checks
This patch will cause the parser to abort if it detects an icc profile
with an invalid size. This is particularly important if the icc profile
is entropy-encoded with zero bits per symbol, as it can prevent a
seemingly infinite loop during parsing.Fixes : infinite loop
Fixes : 62374/clusterfuzz-testcase-minimized-ffmpeg_IO_DEMUXER_fuzzer

How to encode audio to AAC with profile FF_PROFILE_AAC_LOW
13 octobre 2023, par alijandroI try to encode audio to AAC with profile
FF_PROFILE_AAC_LOW
by the following settings.


oc_cxt->profile = FF_PROFILE_AAC_LOW;




Also from the output of
av_dump_format
, I got this


Metadata:
encoder : Lavf57.36.100
Stream #0:0: Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 192 kb/s




But the output is different. Everything is ok, except the output is
AAC
, notAAC (LC)
. By usingffprobe
to detect, the output information is


$ ffprobe o.m4a
...
Stream #0:0(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 195 kb/s (default)
...




AAC (LC)
is the desired result I need.


But from the command line,
ffmpeg
can generateAAC (LC)
output. Below is a small test.


$ ffmpeg -f lavfi -i aevalsrc="sin(440*2*PI*t):d=5" aevalsrc.m4a
$ ffprobe aevalsrc.m4a
...
Stream #0:0(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, mono, fltp, 69 kb/s (default)
...




How can I select
FF_PROFILE_LOW
to getAAC (LC)
output ?

avcodec/videotoolboxenc : Check and set hevc profile
12 octobre 2023, par Zhao Zhiliavcodec/videotoolboxenc : Check and set hevc profile
1. If user don't specify the profile, set it to main10 when pixel
format is 10 bits. Before the patch, videotoolbox output main
profile bitstream with 10 bit input, which can be confusing.
2. Warning when user set profile to main explicitly with 10 bit
input. It works, but not the best choice.
3. Reject main 10 profile with 8 bit input, it doesn't work.Signed-off-by : Zhao Zhili <zhilizhao@tencent.com>
