Subject: [FFmpeg-devel] [PATCH v2] examples/transcoding: Fix time_base handling
Date: Wed, 5 Feb 2025 15:08:00 +0800
Message-ID: <tencent_B9015FD2D812D48056E8CBC049E2C8F3AC06@qq.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 411 bytes --]
The `dec_ctx->time_base` was incorrectly default set by avcodec_open2(), while `enc_ctx->time_base` was derived from `dec_ctx->framerate`. This mismatch could cause incorrect video duration in the output.
This patch corrects the issue by adjusting the `enc_ctx->time_base` calculation to account for `ticks_per_frame`, ensuring that the time base is consistent between the decoder and encoder contexts.
