Commit 6b05263b44 for ffmpeg
commit 6b05263b44c0e0915873cf258fed9b89db968e4b
Author: Jun Zhao <barryjzhao@tencent.com>
Date: Sat Oct 24 15:40:00 2026 +0800
tests/fate: add an AU G.726LE encoding tag round-trip test
Cover 2-, 3-, 4- and 5-bit G.726LE, bit-rate fallback when
bits_per_coded_sample is unset, and rejection of unsupported bit widths.
Compare explicit widths with bitrate fallback for two-channel streams too.
Use an initialized payload and the existing memory-backed AVIO helper for
deterministic readback without custom read/seek callbacks.
