commit 7646bb4c42e6837a9396c3d9ab8d8cf476e2053b Author: Joshua Rogers <[email protected]> AuthorDate: Tue Aug 4 12:11:55 2026 +0000 Commit: Michael Niedermayer <[email protected]> CommitDate: Wed Aug 12 04:52:00 2026 +0200 avformat/rtpenc_av1: do not narrow the OBU size to (long) (long)obu_size sign-flips values in 0x80000000..0xfffffffd on ILP32/LLP64 targets (32-bit long, e.g. 64-bit Windows), bypassing the size check. Compare as uint32_t; frame_size is non-negative at this point. No PoC as the used setup was 64bit specific (cherry picked from commit b4c199c5906ff53368926c2a5839881f41957e7f) Signed-off-by: Michael Niedermayer <[email protected]> --- libavformat/rtpenc_av1.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavformat/rtpenc_av1.c b/libavformat/rtpenc_av1.c index 934cfb63a3..f7c6aad47a 100644 --- a/libavformat/rtpenc_av1.c +++ b/libavformat/rtpenc_av1.c @@ -177,7 +177,7 @@ void ff_rtp_send_av1(AVFormatContext *ctx, const uint8_t *frame_buf, int frame_s return; } - if ((long) obu_size > frame_size) { + if (obu_size > (unsigned) frame_size) { av_log(ctx, AV_LOG_ERROR, "AV1 OBU size %d larger than remaining frame size %d\n", obu_size, frame_size); return; } _______________________________________________ ffmpeg-cvslog mailing list -- [email protected] To unsubscribe send an email to [email protected]
