[FFmpeg-devel] [PATCH v1] avformat/mpegts: fix avformat_find_stream_info take too time with open single video/audio TS stream

[gaojiangjie]

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.
