Re: [Linphone-users] how to set video codec

[Tahir Jilani]

Hi, I apologize for the dealy in response.

In an earlier project for Android application based on linphone. I was controlling video size and quality from cloud for a specific user like this:

public void setPreferredVideoSize(String preferredVideoSizeFromServer) {

int bandwidth = 512; // VGA (640x480)

if (preferredVideoSizeFromServer) .equals("720p")) { //hd

bandwidth = 1024 + 128;

} else if (preferredVideoSizeFromServer) .equals("qvga")) { //QVGA (320x240)

bandwidth = 380;

}  else if (preferredVideoSizeFromServer) .equals("qcif")) { //qcif

bandwidth = 256;

}

LinphoneManager.getLinphoneCore().setPreferredVideoSizeByName(preferredVideoSize);

LinphoneManager.getLinphoneCore().setUploadBandwidth(bandwidth);

LinphoneManager.getLinphoneCore().setDownloadBandwidth(bandwidth);

}

LinphoneCore.java:

these methods are written as:

/**

* Sets the preferred video size giving a known size name.

*

* This applies only to the stream that is captured and sent to the remote party,

* since we accept all standard video size on the receive path.

* @param name A known video name (eg. vga or 720p)

**/

void setPreferredVideoSizeByName(String name);

void setUploadBandwidth(int bw);

/**

* Sets maximum available download bandwidth

*

*

* This is IP bandwidth, in kbit/s.

* This information is used signaled to other parties during

* calls (within SDP messages) so that the remote end can have

* sufficient knowledge to properly configure its audio & video

* codec output bitrate to not overflow available bandwidth.

*

* @param bw the bandwidth in kbits/s, 0 for infinite

*/

void setDownloadBandwidth(int bw);

Regards,

Tahir

What platform are you running the linphone on? Is it Android, iOS ?

Hello,

I'm trying to place video calls with linphone but with H263 I receive the following error:

linphonec> 2016-02-13 15:49:50:888 ortp-error-no such method on filter MSH263Enc, fid=16392 method index=8

Valid sizes are 128x96, 176x144, 352x288, 704x576, and 1408x1152.Try H.263+.
2016-02-13 15:49:52:843 ortp-error-avcodec_open() failed: -1

I've tried to change size parameter in .linphonerc with qcif, cif, vga, 4cif but result is always the same. Is there any way to change video size for H263 codec?

With H264 video works, but quality is not satisfactory

anyone can help me?
