FFmpeg:协议不在白名单“文件"上！ [英] FFmpeg: Protocol not on whitelist 'file'!

问题描述

我想从RTP流中读取，但是当我在avformat_open_input()中指定"test.sdp"时，会显示以下消息:

I want to read from an RTP stream, but when I specify "test.sdp" to avformat_open_input() I get this message:

[rtp @ 03928900] Protocol not on whitelist 'file'!
Failed: cannot open input.
avformat_open_input() fail: Invalid data found when processing input

通常，如果我在控制台上使用ffplay，我会添加选项-protocol_whitelist file,udp,rtp，它将正常工作.

Normally if I were using ffplay on the console, I would add the option -protocol_whitelist file,udp,rtp and it would work fine.

所以我尝试了这个:

AVDictionary *d = NULL;           
av_dict_set(&d, "protocol_whitelist", "file, udp, rtp", 0); 
ret = avformat_open_input(&inFormatCtx, filename, NULL, &d);

但是仍然弹出相同的消息.有什么想法吗?

But the same message still pops up. Any ideas?

推荐答案

这很尴尬...

avformat_open_input失败，因为我有空格.现在可以删除空格.

avformat_open_input failed because I have white spaces. Removing the whitespaces now work.

av_dict_set(&d, "protocol_whitelist", "file,udp,rtp", 0);
