OK. I admit it. I'm being thick.
How do I write a single frame from any video source to a jpeg file. The command line version of FFMPEG will obviously do it, and the libavcodec source file mjepgenc.c will write the JFIF header, so I would guess that getting the library to do all the tedious DCT stuff for me should be fairly obvious, it's just that I can't quite see how at the moment. Is it as simple as using img_convert to set the output format to one of the PIX_FMT_YUVJ4xxP formats and writing the resulting AVPicture data to disk (as I would if it were a PPM/PGM file that I needed to create)? Sorry if the answer's obvious and I've just missed something.
