Subject: [FFmpeg-devel] [PATCH] avformat/mpegts: initialize max_packet_size when sub-demuxer
Date: Sat, 5 Feb 2022 18:52:42 +0530
Message-ID: <20220205132242.52049-1-ffmpeg@gyani.pro> (raw)
bca30570d2 added a user option to set max_packet_size replacing
a hardcoded value. This had a side-effect of leaving the field
set to 0 when packet demuxing is carried out from another demuxer
using avpriv functions, which could lead to demux failure.
Hardcoded max_packet_size inside avpriv_mpegts_parse_open to
2048000 to avoid this. Value chosen to be 10x that of default value
to accommodate large payloads.
