commit 68e18d3a1cf7c8c83360260d7025de4a03d8a3b7 Author: Jun Zhao <[email protected]> AuthorDate: Mon Mar 9 08:40:53 2026 +0800 Commit: toots <[email protected]> CommitDate: Wed Mar 18 02:08:09 2026 +0000 doc/examples/encode_audio: fix hardcoded stereo sample stride The sample generation loop hardcodes a stride of 2 (stereo) with samples[2*j], but the channel count is dynamically selected by select_channel_layout() which picks the layout with the highest channel count. If the encoder supports more than 2 channels, samples will be written at wrong offsets. Use c->ch_layout.nb_channels as the stride instead.
