Hello guys, I used to program myself to organize video sources and then live broadcast it, but I was so tired to implement complex functions until I found CasparCG, it is all what I need.
I need some function which can be done by FFMpeg parameters, but looking into CasparCG wiki, I don’t how to use FFMpeg parameters as producer (not as consumer)
for exmaple, I need "rtsp_transport tcp " for rtsp stream
when I do
play 1-9 rtsp://172.16.10.3:8554/vlc -rtsp_transport tcp
rtsp video played, but still shows udp on the log, did I put it wrong or is it not supported?
any suggestion?
also, I will need to do 3d lut apply to video stream by using ffmpeg parameters later
I succeed to get 3dlut filter working
but still no luck on -rtsp_transport tcp
without this, I got a lot packet missing error

and video got glitch sometimes
I did a workaround
just add some code
if (url_parts.first == L"http" || url_parts.first == L"https") {
FF(av_dict_set(&options, "http_persistent", "0", 0)); // NOTE https://trac.ffmpeg.org/ticket/7034#comment:3
FF(av_dict_set(&options, "http_multiple", "0", 0)); // NOTE https://trac.ffmpeg.org/ticket/7034#comment:3
FF(av_dict_set(&options, "reconnect", "1", 0)); // HTTP reconnect
FF(av_dict_set(&options, "referer", filename_.c_str(), 0)); // HTTP referer header
} else if (url_parts.first == L"rtmp" || url_parts.first == L"rtmps") {
FF(av_dict_set(&options, "rtmp_live", "live", 0)); // HTTP referer header
}
**else if (url_parts.first == L"rtsp" || url_parts.first == L"rtsps") {**
** FF(av_dict_set(&options, "rtsp_transport", "tcp", 0)); // HTTP referer header**
** }**
hopefully, it will be fixed in future release
it’s me again,
I just tried to enable Nvdec for decoding, but no lock, any one have some ideas?
FF(av_dict_set(&options, "hwaccel", "cuvid", 0)); // HTTP referer header
FF(av_dict_set(&options, "codec:v", "h264_cuvid", 0)); // HTTP referer header
hello wher is this file or location to edit ?
thanks
just search the whole code “rtmp”
you will find the location, and then add rtsp parameters for rtsp stream
