conversationRequest: fail to send group request with avatar

Should be handled by a test in conversationRequest (big payload)

Scenario

• On client-qt (I'm a bit out-of-date 202408241514), create a group, add avatar and title
• Image used for avatar:
• Add a connected contact to the swarm

Expected

• Request is sent

Current result

• Request fails
• PJ_ETOOLONG error

@AmarOk1412 Interesting, because this reproduces one of the rare cases that never worked.

There is a 64000 limit that prevents invitations to exceed the DHT max value size, however PJSIP_MAX_PKT_LEN was always set to 8000, causing the problem when the profile size is between 8000 and 64000, which happens when selecting your image with the Qt client.

The obvious fix is to increase PJSIP_MAX_PKT_LEN to more than 64000, such as 65536.

If the image (avatar) makes the profile size more than PJSIP_MAX_PKT_LEN will:

1. the user be prompted with a dialog box that the image size is too large and that the image will not be added? Perhaps there could be an error message advising something like reduce the image size and try again.
2. the user be prompted with a dialog box that the image size is too large and the image will be automatically reduced?
3. the user be prompted with a dialog box that the image size it too large and that the image will be reduce to maximum dimensions of, say, 256 pixels by 256 pixels keeping the original ratio.

Thank you

Some of codecs support target size, but the values of BPP (Bits Per Pixels) will probably be much lower than 1.

Was trying to figure out for the longest time why invites wern't being sent. It was because I had an avatar set for the swarm. This is a really annoying glitch lol.
