Hi all, I've been trying to build a demo app where you can make audio and video calls. I'm using pjsip 2.1.0 with ffmpeg and h264. I'm also using the ios_dev.mmfile and libyuv library that Samuel worked out. I changed some code to present the main and preview windows. My problem: Although i'm able to send video packets correctly, i cannot figure out how to present the ones i'm getting. I get nothing but a green window. When i'm lucky i'm able to see a distorted image. I noticed that there are some ffmpeg errors showing up on the console: *15:53:18.130 ffmpeg h264: non-existing PPS 0 referenced* *15:53:18.130 ffmpeg h264: decode_slice_header error* *15:53:18.130 ffmpeg h264: no frame!* *15:53:18.130 ffmpeg_vid_cod ffmpeg err -1: Operation not permitted* *15:53:18.130 vstdec0x1ada01 codec decode() error: Bad or corrupted bitstream (PJMEDIA_CODEC_EBADBITSTREAM) [err:220087]* When debugging it looks like we're converting a YUV image to a BGRA one, and then presenting it. It all looks good. Does anyone have any hints? Could it be a wrong configuration when compiling ffmpeg or x264? Thank you very much, Jules -------------- next part -------------- An HTML attachment was scrubbed...
