我曾經不得不從IP攝像機（Sony SRG 300SE）錄製視頻。我通過啓動從硬盤上（已錄製）原始RTSP流中解複用H264
gst-launch-1.0 rtspsrc location="rtsp://192.168.0.100/video1" ! filesink location="recording.raw"
它完美地跑這樣做了。 現在，我想從該文件解複用音頻和視頻（aac和h264）。我現在知道，在接收流時做這件事會更聰明，但是，我沒有。
我已經嘗試過
gst-launch-1.0 rtspsrc location="recording.raw" ! ...，這會導致 「沒有有效的RTSP URL中提供」（GStreamer的1.10.2）;ffmpeg -i recording.raw -c:v copy -c:a copy recording.mp4，這隻會導致「處理輸入時發現無效數據」（3.2.2的ffmpeg）gst-launch-1.0 filesrc location="recording.raw" ! application/x-rtp ! rtph264depay ! h264parse ! matroskamux ! filesink location=out.mkv，導致WARNING: from element /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0: Could not decode stream. Additional debug info: gstrtpbasedepayload.c(503): gst_rtp_base_depayload_handle_buffer(): /GstPipeline:pipeline0/GstRtpH264Depay:rtph264depay0: Received invalid RTP payload, dropping
有什麼辦法，我得到至少視頻輸出的那個流？
更新： 4. cat recording.raw | ffmpeg -i - -c:v copy -c:a copy recording.mp4導致pipe:: Invalid data found when processing input在FFMPEG 3.2.2，並在舊的編譯如下：

...從而創造一個AAC只有文件。據我所知，AAC是沉默的（但情況可能如此）。

嘗試'ffmpeg -f rtsp -i file：//recording.raw -c：v複製-c：複製記錄。 mp4'或'cat recording.raw | ffmpeg -i - -c：v copy -c：副本recording.mp4' – Mulvya
謝謝。第一個根本不起作用： FFMPEG用'file：/// [path] /recording.raw：連接被拒絕'退出' 後者給我一個只包含AAC流的文件，沒有視頻。如果我放棄一個'-an'選項，就會得到'輸出文件＃0不包含任何流'，就好像輸入文件中沒有H264流一樣。 –
@aergistal也許你有一些想法。 – Mulvya
