From: Niklas Haas <ffmpeg@haasn.xyz> To: ffmpeg-devel@ffmpeg.org Cc: Niklas Haas <git@haasn.dev> Subject: [FFmpeg-devel] [PATCH] avfilter/vf_libplacebo: don't explode on zero FPS information Date: Mon, 17 Mar 2025 15:24:32 +0100 Message-ID: <20250317142432.403855-1-ffmpeg@haasn.xyz> (raw) From: Niklas Haas <git@haasn.dev> While technically not specifiad as valid by the AVFilterLink documentation, it is currently possible to get an FPS of zero from various sources inside libavfilter (notably vf_buffersrc). Avoid a division by zero and resulting infinity when this happens. --- libavfilter/vf_libplacebo.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavfilter/vf_libplacebo.c b/libavfilter/vf_libplacebo.c index 0c245cda7f..86e1f43dea 100644 --- a/libavfilter/vf_libplacebo.c +++ b/libavfilter/vf_libplacebo.c @@ -1073,7 +1073,7 @@ static int libplacebo_activate(AVFilterContext *ctx) in->qstatus = pl_queue_update(in->queue, &in->mix, pl_queue_params( .pts = out_pts * av_q2d(outlink->time_base), .radius = pl_frame_mix_radius(&s->opts->params), - .vsync_duration = av_q2d(av_inv_q(l->frame_rate)), + .vsync_duration = l->frame_rate.num ? av_q2d(av_inv_q(l->frame_rate)) : 0, )); switch (in->qstatus) { -- 2.48.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
