23  * Pixel remap filter
24  * This filter copies pixel by pixel a source frame to a target frame.
25  * It remaps the pixels to a new x,y destination based on two files ymap/xmap.
26  * Map files are passed as a parameter and are in PGM format (P2 or P5),
27  * where the values are y(rows)/x(cols) coordinates of the source_frame.
28  * The *target* frame dimension is based on mapfile dimensions: specified in the
29  * header of the mapfile and reflected in the number of datavalues.
30  * Dimensions of ymap and xmap must be equal. Datavalues must be positive or zero.
31  * Any datavalue in the ymap or xmap which value is higher
32  * then the *source* frame height or width is silently ignored, leaving a
33  * blank/chromakey pixel. This can safely be used as a feature to create overlays.
34  *
35  * Algorithm digest:
36  * Target_frame[y][x] = Source_frame[ ymap[y][x] ][ [xmap[y][x] ];

AVERROR
Filter the word “frame” indicates either a video frame or a group of audio as stored in an AVFrame structure Format for each input and each output the list of supported formats For video that means pixel format For audio that means channel sample they are references to shared objects When the negotiation mechanism computes the intersection of the formats supported at each end of a all references to both lists are replaced with a reference to the intersection And when a single format is eventually chosen for a link amongst the remaining all references to the list are updated That means that if a filter requires that its input and output have the same format amongst a supported all it has to do is use a reference to the same list of formats query_formats can leave some formats unset and return AVERROR(EAGAIN) to cause the negotiation mechanism toagain later. That can be used by filters with complex requirements to use the format negotiated on one link to set the formats supported on another. Frame references ownership and permissions
