Module concat_transcode 

Concatenation and joining of multiple media sources. Concatenation and joining of multiple media sources into a single output.

Handles cross-format joining with optional transition effects between segments, automatic audio/video alignment, and gap filling.

Mixed-Source Concatenation

MixedSourceConcatenator handles sequences where sources have different resolutions, frame rates, or codecs. It analyses each source segment, determines whether re-encoding is required, and produces a ConcatPlan that the caller can execute.

Functions
