commit 3cdd76ba96ab331c30d442769f49c2331a7780f8 Author: Jun Zhao <[email protected]> AuthorDate: Sun Apr 19 08:42:45 2026 +0800 Commit: Jun Zhao <[email protected]> CommitDate: Tue Apr 28 06:14:38 2026 +0000 avcodec/libsvtav1: reject tiny inputs on SVT-AV1 < 3.0.0 SVT-AV1 < 3.0.0 requires input dimensions of at least 64x64. Older versions may otherwise silently accept smaller inputs without producing output and cause the caller to hang. Reject such inputs explicitly in config_enc_params() to produce a clear error. v3.0.0+ supports sub-64px dimensions and validates the input itself, so the check is gated with SVT_AV1_CHECK_VERSION.
