Subject: [FFmpeg-devel] [PATCH v2] avformat/mpegts: fix the issue where the PMT table can't be retrieved.
Date: Fri, 28 Nov 2025 13:21:09 +0800
Message-ID: <20251128052109.151-1-ganqiuye@gmail.com> (raw)
In-Reply-To: <20251127105233.473-1-ganqiuye@gmail.com>

When analysing PAT, if sid 0 and pmt_pid 0 (current_pid 0 as pat_pid),
it will break out of the loop, so it can't retrieve the next pmt_pid.
