Function Documentation

pjmedia_vid_codec_h263_parse_fmtp()

pj_status_t pjmedia_vid_codec_h263_parse_fmtp	(	const pjmedia_codec_fmtp *	fmtp,
		pjmedia_vid_codec_h263_fmtp *	h263_fmtp
	)

Parse SDP fmtp of H.263.

Parameters

fmtp	The H.263 SDP fmtp to be parsed.
h263_fmtp	The parsing result.

Returns

PJ_SUCCESS on success.

pjmedia_vid_codec_h263_apply_fmtp()

pj_status_t pjmedia_vid_codec_h263_apply_fmtp

(

pjmedia_vid_codec_param *

param

)

Parse, negotiate, and apply the encoding and decoding SDP fmtp of H.263 in the specified codec parameter.

Parameters

param

The codec parameter.

Returns

PJ_SUCCESS on success.

pjmedia_vid_codec_h264_parse_fmtp()

pj_status_t pjmedia_vid_codec_h264_parse_fmtp	(	const pjmedia_codec_fmtp *	fmtp,
		pjmedia_vid_codec_h264_fmtp *	h264_fmtp
	)

Parse SDP fmtp of H.264.

Parameters

fmtp	The H.264 SDP fmtp to be parsed.
h264_fmtp	The parsing result.

Returns

PJ_SUCCESS on success.

pjmedia_vid_codec_h264_match_sdp()

pj_status_t pjmedia_vid_codec_h264_match_sdp	(	pj_pool_t *	pool,
		pjmedia_sdp_media *	offer,
		unsigned	o_fmt_idx,
		pjmedia_sdp_media *	answer,
		unsigned	a_fmt_idx,
		unsigned	option
	)

Match H.264 format in the SDP media offer and answer. This will compare H.264 identifier parameters in SDP fmtp, i.e: "profile-level-id" and "packetization-mode" fields. For better interoperability, when the option PJMEDIA_SDP_NEG_FMT_MATCH_ALLOW_MODIFY_ANSWER is set, this function may update the answer so the parameters in the answer match to ones in the offer.

Parameters

pool	The memory pool.
offer	The SDP media offer.
o_fmt_idx	Index of the H.264 format in the SDP media offer.
answer	The SDP media answer.
a_fmt_idx	Index of the H.264 format in the SDP media answer.
option	The format matching option, see pjmedia_sdp_neg_fmt_match_flag.

Returns

PJ_SUCCESS when the formats in offer and answer match.

pjmedia_vid_codec_h264_apply_fmtp()

pj_status_t pjmedia_vid_codec_h264_apply_fmtp

(

pjmedia_vid_codec_param *

param

)

Parse and apply the encoding and decoding SDP fmtp of H.264 in the specified codec parameter. This will validate size and fps to conform to H.264 level specified in SDP fmtp "profile-level-id".

Parameters

param

The codec parameter.

Returns

PJ_SUCCESS on success.

pjmedia_vid_codec_vpx_parse_fmtp()

pj_status_t pjmedia_vid_codec_vpx_parse_fmtp	(	const pjmedia_codec_fmtp *	fmtp,
		pjmedia_vid_codec_vpx_fmtp *	vpx_fmtp
	)

Parse SDP fmtp of VPX.

Parameters

fmtp	The VPX SDP fmtp to be parsed.
vpx_fmtp	The parsing result.

Returns

PJ_SUCCESS on success.

pjmedia_vid_codec_vpx_apply_fmtp()

pj_status_t pjmedia_vid_codec_vpx_apply_fmtp

(

pjmedia_vid_codec_param *

param

)

Parse and apply the encoding and decoding SDP fmtp of VPX in the specified codec parameter. This will validate size and fps to conform to VPX level specified in SDP fmtp "max-fr" and "max-fs".

Parameters

param

The codec parameter.

Returns

PJ_SUCCESS on success.
