    用ffmpeg -i 'rtmp://xxx'会报以下错误

    [h264 @ 0x7fc471809c00] missing picture in access unit with size 242

    像是推流过程中某些NAL丢失了图像帧

    网络应该没有问题,pilot和我本地电脑用的都是wifi,本地电脑用OBS推同样码率和分辨率的视频流没有出现这些报错

    不好意思,我让飞手重新拍了下照片,是这个版本号,之前我看的mqtt发上来的firmware_version,看岔了,看成电池的固件版本了。。。

    webrtc对网络要求会高一点, 本地电脑用OBS推同样码率和分辨率的视频流时,移动端拉流会卡顿吗?

    不论是将rtmp转为webrtc,还是hls,移动端都卡顿,移动端直接用的chrome或者safari播放的hls,pc端浏览器播放没有任何问题

    但是用obs推同样码率和分辨率的视频流,移动端用浏览器就不会卡

    目前如果不转webrtc或者hls,直接播放rtmp格式会卡顿吗?

    移动端由于浏览器不能直接播放rtmp,用的移动端的vlc播放的,vlc不论是播放rtmp还是hls都不卡顿(移动端浏览器hls卡顿),查了下资料,可能是pc端浏览器和vlc对于视频的容错率高,移动端浏览器的容错率低,应该还是推流侧的码流有些问题

    这样的话只能拉日志进行分析了。
