Subject: [FFmpeg-devel] [PATCH v1] avformat/mpegts: fix avformat_find_stream_info take too time with open single video/audio TS stream
Date: Mon, 16 May 2022 19:35:24 +0800
Message-ID: <TYCP286MB2608ADF800E6A464B1BB9F4BC7CF9@TYCP286MB2608.JPNP286.PROD.OUTLOOK.COM> (raw)
From: Jiangjie Gao <gaojiangjie@live.com>
1. ref https://trac.ffmpeg.org/ticket/9782.
2. just check `codec_type`.
3. remove `pos > 100000`, we have AVFormatContext::probesize.
