Andriy Gelman 662accb728 lavc/cbs_h2645_syntax_template: Fix memleak 
payload_count is used to track the number of SEI payloads. It is also
used to free the SEIs in cbs_h264_free_sei()/cbs_h265_free_sei().

Currently, payload_count is set after for loop is completed. Hence if
there is an error and the function exits, the payload remains zero
causing a memleak.

This commit keeps track of payload_count inside the for loop to fix the
issue. Note that that the contents of current are initialized with
av_mallocz() so there is no need to zero initialize payload_count.

  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
