Member Function Documentation

◆ compare_timestamp()

int FfmpegVideoCursor::FfmpegBuffer::compare_timestamp ( const Buffer other) const
virtual

Used to sort different buffers to ensure they correspond to the same source frame, particularly important when synchronizing the different pages of a multi-page texture.

Returns 0 if the two buffers are of the same frame, <0 if this one comes earlier than the other one, and >0 if the other one comes earlier.

Definition at line 1261 of file ffmpegVideoCursor.cxx.

◆ get_timestamp()

double FfmpegVideoCursor::FfmpegBuffer::get_timestamp ( ) const
virtual

Returns the nearest timestamp value of this particular buffer.

Ideally, MovieVideoCursor::set_time() for this timestamp would return this buffer again. This need be defined only if compare_timestamp() is also defined.
