[Libav-user] How to set AVInputFormat when using AVCodec (For Mobotix MxPEG stream)

[Gal Bar Mashiah]

Is it possible to set a specific AVInputFormat when working with the
AVCodec functions?

The way I'm trying to decode the video is:

*ppCodec = avcodec_find_decoder(AV_CODEC_ID_MXPEG);

*ppCodecContext = avcodec_alloc_context3(*ppCodec);

avcodec_open2(*ppCodecContext, *ppCodec, NULL)

and then decode using avcodec_decode_video2(...)

The decode succeeds only for the first frame. I think I need to set the
AVInputFormat to "mxg" in order for this to work for the Mobotix MxPEG
stream, but I'm not sure how.

The error message I'm getting is that got_picture_ptr from
avcodec_decode_video2 returns with 0 for all but the first frame.
