Ffmpeg
RTSP 通過 ffmpeg
我有 4 個無名 ip-cams 並且在擷取 rtsp 流時遇到了麻煩。隨機輸出文件甚至沒有創建。我正在通過 ffmpeg 擷取流。在帶有 snap ffmpeg 的 Ubuntu Server 18.04 和帶有普通 ffmpeg 的 Debian 7 上進行了嘗試。同樣的麻煩。
(/snap/bin/ffmpeg -y -use_wallclock_as_timestamps 1 -hide_banner -loglevel trace -i rtsp://192.168.0.16$1:554/11 -c:v copy -an -flags +global_header $VIDEO_FILE 2> $LOG_FOLDER/cam$1 ) &嘗試過*-loglevel 調試*，但它只顯示成功的 RTSP 連接，僅此而已。使用*-loglevel 跟踪*，我注意到成功和失敗程序之間的區別。

日誌文件未滿，但我認為已經足夠了。這隨機出現在隨機凸輪上。
如何解決？
我自己找到了解決方案。我的問題是數據包的真實性。我嘗試添加強制 tcp 連接標誌（-rtsp_transport tcp）並且它有效。沒有問題了。
