export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-decoder=pcm_alaw"

pcm_alaw decode 打开没有 ？

[flyMan1991]

已经打开,但是还是无法播放,已经设置传输协议为tcp了; 视频地址为:rtsp://admin:admin@59.53.175.163:14554/snl/live/1/2; 请给解决一下问题,谢谢 ffmpeg测试调试信息为:Could not find codec parameters for stream 0 (Video: h264, none, 704x576): unspecified pixel format Consider increasing the value for the 'analyzeduration' and 'probesize' options Input #0, rtsp, from 'rtsp://admin:admin@59.53.175.163:14554/snl/live/1/2': Metadata: title : NVT comment : From NVT Duration: N/A, bitrate: 64 kb/s Stream #0:0: Video: h264, none, 704x576, 90k tbr, 90k tbn, 180k tbc Stream #0:1: Audio: pcm_alaw, 8000 Hz, 1 channels, s16, 64 kb/s Stream #0:2: Data: none Unsupported codec with id 0 for input stream 2 [rtsp @ 0x7fe421002a00] UDP timeout, retrying with TCP 具体不知道问题出在那里:

[muyitimha]

因为你在编译ffmpeg时配置文件里的描述是不支持rtsp的

@flyMan1991 你好，请问，你这个问题后来是怎么解决的？

[yjjwxy2]

@flyMan1991 也遇到这个问题。声音有但是不清楚，都是杂音根本听不清
