  • FFMPEG + HDFS - how to use ffmpeg libraries (.libs) to get file IO in and out of HDFS ?

    15 décembre 2015, par eric frazer

    I’m programming in C, C++, and need ffmpeg to read and write files to HDFS. I know ffmpeg can decompress from packets I already have, but I don’t know how to get it to read from the header, or get it to write to my stream. I don’t look forward to cracking open the source for ffmpeg and writing it myself. It’d be nice if ffmpeg had some ability to read/write from something that looks like an IStream. Has anybody done this ? I also know about mounting the HDFS system on my local machine, but that’s a last resort. Note this question IS specific, and it is about programming, not soliciting advice. Need insight into ffmpeg’s .LIB API and how to get it to read/write from an object I point it to.

  • FFMPEG video streaming error

    2 octobre 2013, par Vigo

    I have downloaded FFMPEG static builds for carrying out audio/video streaming on a LAN. A webcam captures the video and this has to be streamed. I use the following command to know the name of the video device connected.

    ffmpeg -list_devices true -f dshow -i dummy  

    The webcam connected is "USB Video Device".
    Next i use the following command to transmit the video.

    ffmpeg -f dshow -i video="USB Video Device" -vcodec libx264 -tune zerolatency -b 900k -f rtp rtp://10.1.0.102:1234  

    But it throws me the error "Could not run filter. video=USB Video Device : Input/output error" as shown below.

    Please let me know what is the issue here.

  • How to extract H264 video from RTP packets in a .pcap file

    29 septembre 2020, par Ke Chen

    I am using FFmpeg to transmit RTP stream of a video and then capture and save all packets using WireShark into a .pcap file. The FFmpeg command I am using is :

    


    ffmpeg -i video.264 -r 25 -video_size 352x288 -c:v libx264 -f  rtp rtp://127.0.0.1:1234


    


    Now, I want to convert back to video using this pcap file. Can FFmpeg do this ? or Is there other tools available ?

    


    Also, I want to test how packet loss affects the quality of video. So I need to drop several packets in the pcap and then convert back to video to see the effect. Can I get the video back just use the rest of the packets in the pcap file ?

    


    To achieve the goal I said above, I also need to learn which packets are corresponding to what kind of frames right ? So can I acquire the type of frames only looking at the RTP packets in the file. How can I do that ?
