Frame size, frame rate abbreviations:

Note, the names of encoders and decoders do not always match, so there are several cases where the above table shows encoder only or decoder only entries even though both encoding and decoding are supported. For example, the h263 decoder corresponds to the h263 and h263p encoders, for file formats it is even worse.

Note, the names of encoders and decoders dont always match, so there are several cases where the above table shows encoder only or decoder only entries even though both encoding and decoding are supported for example, the h263 decoder corresponds to the h263 and h263p encoders, for file formats its even worse
