  • Getting av_interleaved_write_frame(): Operation not supported for ffmpeg segment

    31 August 2016, by user1805861

    I am able to get segments of video file in Linux directory by using:

    ffmpeg -i rtmp://10.11.11.11:8080/temp.avi -acodec copy -f segment -segment_time 3 -vcodec copy -reset_timestamps 1 -map 0 -an temp%d.mp4

    But when same command I am using for mounted filesystem I am getting error

    [segment @ 0x47aa8e0] Failure occurred when ending segment 'temp0.mp4'd=1.12x
    
av_interleaved_write_frame(): Operation not supported

    Any ides why is this so?
    I even checked the space available on the mounted file system by df -h but it’s not full.

  • How to use libavformat to concat 2 video files with same codec (re-muxing)?

    27 September 2013, by Tarhan

    I have downloaded videos from CDN in flv format (video H264 and audio AAC) and remux to them to MP4 format. But videos are limited by length. So i've downloaded each video in several parts: started at start point, at point 1, at point 2 (by using seek parameter in url). Each point starts little earlier than ending of previous one.
    Using av_read_frame i scanned all parts and found that intersecting packets not only have same sizes and order but also their dts/pts shifted from each other by constant value. So to concat starting video with video started at point 1 I must do following:
    1. Create output header in output file
    2. Copy all non-intersecting packets from starting video.
    3. Copy all non-intersecting packets from video started at point 1 with changed dts values by shifted it by constant

    How to do all of this using libav (not ffmpeg)? I read How can libavformat be used without using other libav libraries. But in libav it is not working since there not avformat_alloc_output_context2 in libav. Also source avconv.c source is too complex for newbie like me to isolate parts related to stream copy operations.
    Can someone provide me example to:

    - open input_file1 and input_file2 (only needed if procedure differs from standard in generic tutorials)

    - open and write header for output_file with same container format and same video and audio formats

    - write packets from input_file1 to output_file up to packet with for example pos == XXX

    - write packets from input_file2 to output_file changing their dts (or whatever needed) by constant value

    - write correct trailer

    Calculating of time shift in dts i made before.
