Requirements backlog

General

• The features are implemented on latest stable version of MPlayer (1.0-rc2) reference version was changed to rc1
• [Additional] implementation compliant with the development (SVN) version of MPlayer

Black frame detection

• Iteration 1
  • The purpose is to detect black frames from video stream. A frame is considered black if the average colour and the highest individual pixel color value are under certain thresholds
  • The video file is ran through the black frame video filter, which generates EDL files
• Iteration x
  • Together with accurate MPEG TS seek EDL files can be used to skip commercials

Support for DVB subs

• Iteration y
  • Support (decoding & timing) for the bitmap DVB subtitle format which YLE channels use
  • [Additional] Support for coloured subtitles (Weber's patch has grayscale subs) problematic for the possible patch

MPEG TS seek

• Iteration x
  • Seek with 1 second accuracy
  • Handles the "26th hour" PTS reset (33-bit counter resets)
  • Handles other PTS resets (examines where the reset happened)
  • [Optional] Handles multiple PTS resets between seek target and current location

Volume filter

• [Optional] Create a new audio filter that can:
  • Change/normalize volume (dynamically) to a certain maximum level
  • Apply a compression to keep the quiet sounds audible if the volume is lowered a lot?

Some DVB subtitle manipulation

• [Optional] Make it easier to use the subs from the DVB stream after it's saved in some other format. Either:
  • Add support for converting the DVB subs to the bitmap-based subtitle format often used with DVD backups
  • Add support for "burning" the subs into the video when converting to some other format (turning them into "hard" subs).
