hello guys im coding a new webrtc while the codec function works fine in chrome edge brave browsers it picks opus and H246 If i try opera gx it pick rtx and AUDIO G722

function forceH264Codec(sdp) {
    const lines = sdp.split('\r\n');
    let mLineIndex = -1;
    for (let i = 0; i < lines.length; i++) {
        if (lines[i].startsWith('m=video')) {
            mLineIndex = i;
            break;
        }
    }

    if (mLineIndex === -1) {
        console.warn("No 'm=video' line found in SDP, cannot force H264");
        return sdp;
    }

    const h264PayloadTypes = lines
        .filter(line => line.startsWith('a=rtpmap') && line.includes('H264'))
        .map(line => line.split(':')[1].split(' ')[0]);

    if (h264PayloadTypes.length === 0) {
        console.warn("No H264 payload types found in SDP, cannot force H264");
        return sdp;
    }

    const originalMLine = lines[mLineIndex];
    const mLineParts = originalMLine.split(' ');
    let preferredMLine = mLineParts.slice(0, 3); // 'm=video', port, protocol
    preferredMLine.push(...h264PayloadTypes); // Add H264 payload types first

    // Add back other non-H264 payload types if any were present (though usually not needed when forcing H264)
    const existingPayloadTypes = new Set(mLineParts.slice(3));
    const otherPayloadTypes = [...existingPayloadTypes].filter(pt => !h264PayloadTypes.includes(pt)); // Ensure no duplicates
    preferredMLine.push(...otherPayloadTypes);


    lines[mLineIndex] = preferredMLine.join(' ');
    return lines.join('\r\n');
}

@BOSSXXXL I don't think you can add codecs to Opera

@leocg I'm not trying to add actually the codecs are already there but the parameters are different from chrome

@BOSSXXXL Maybe Opera uses different codecs?
