Hi,
The following part in the function "gst_x264_enc_header_buf" is changed in
the latest release of gst-plugin-ugly.
From:
buffer[0] = 1; /* AVC Decoder Configuration Record ver. 1
*/
buffer[1] = sps[0]; /* profile_idc
*/
buffer[2] = sps[1]; /* profile_compability
*/
buffer[3] = sps[2]; /* level_idc
*/
buffer[4] = 0xfc | (4 - 1); /* nal_length_size_minus1
*/
To:
buffer[0] = 1; /* AVC Decoder Configuration Record ver. 1
*/
buffer[1] = sps[1]; /* profile_idc
*/
buffer[2] = sps[2]; /* profile_compability
*/
buffer[3] = sps[3]; /* level_idc
*/
buffer[4] = 0xfc | (4 - 1); /* nal_length_size_minus1
*/
Ubuntu uses libx264 of build 67. At least for this version, I think the
original implementation was right. I do not understand why it was changed.
Please help.
Thanks,
Yiliang
