Title Body

I'm looking for some universal way to dump rtsp stream. I want to figure out, that some rtsp stream is working well and server is sending some watchable video. openRTSP At first, google recommends me openRTSP tool. openRTSP -4 ${stream_link} > ${output_file} But output video file dumped by that tool is not really correct. Video decoder (ffdec) returns many errors like "Failed to decode video packet" and "[h264] no frame!", which don't suit me. ffmpeg Then I've tried to dump rtsp stream with ffmpeg tool. ffmpeg -loglevel debug -i "${stream_link}" -s 640x480 -vcodec copy -acodec copy -y ${output_file} But streaming process was interrupted often by error: Application provided invalid, non monotonically increasing dts to muxer in stream 0: 730672 >= 730672 av_interleaved_write_frame(): Invalid argument I'm trying to use --fflags igndts but ffmpeg doesn't ignore these errors. It doesn't make any sense, because that error actually means that audio and video streams are sending asynchronously. The worst thing is that dumped file, resulted by that interrupted dump, is not correct too. Ffdec return some error: ERROR [mov,mp4,m4a,3gp,3g2,mj2] moov atom not found ERROR [ffdec] av_open_input_file: Operation not permitted After a nice cup of googling I've found, that it's really old ffmpeg's muxer bug . mplayer Than I've tried to use mplayer with LIVE_555 lib. mplayer -noframedrop -dumpfile ${output_file} -dumpstream ${stream_link} But I've got some errors too. Stream not seekable! Core dumped ;) Question I think I'm doing somethin
