  • Support audio et vidéo HTML5

    10 avril 2011

  • FFmpeg : Reading data from 2 FIFO

    21 septembre 2019, par user3497661

    I am working with FFmpeg 4.1.3. I am trying to read video from one named pipe and audio from another named pipe and creating a new output file. There are 2 RTP processes reading data over the network and writing it to these pipes.

    I am using following commandline
    ffmpeg -report -i /tmp/audio_pipe.pcmu -i /tmp/video_pipe.h264 -y output.ts
    When I try to receive from individual pipes,
    (ffmpeg -report -i /tmp/audio_pipe.pcmu -y output.ts), it works but using 2 pipes in the same command line seems to block.
    I found some 7 year old ticket https://trac.ffmpeg.org/ticket/1663. It says that multiple pipes do not work with FFmpeg.

    I would like to know if input using multiple pipes works with FFmpeg now and if yes, how to achieve it.

  • Detect duplicate frames to create seamless loops in FFMPEG

    19 septembre 2017, par Yasath Dias

    I feel like this should be possible, after I saw a method created with MoviePy for Python (this article). Essentially, I want to import an MP4 at 1920x1080 with say 12000kbps bitrate and have FFMPEG detect when there are duplicate frames that aren’t consecutive and export each one of these small sequences to small individual MP4 files that loop seamlessly (the first frame is almost the same as the last frame like this one).

    A 1920x1080 file may be far too large (in resolution) to process, so I would be fine with downscaling that to around 120px wide. Also, I know that FFMPEG can detect duplicate frames because I’ve often used mpdecimate previously.

    I hope I described the issue well enough, but will be willing to clarify, of course :)

  • lavc/h264dec : don't error out when receiving multiple IDR slices

    26 septembre 2018, par Josh de Kock
    lavc/h264dec : don't error out when receiving multiple IDR slices

    This error isn't particularly helpful as checking for mixed IDR/non-IDR
    
NALUs would need to be done at a higher level to actually be accurate.
    
Removing the error allows an API user to send individual slice NALUs
    
(i.e. incomplete frames) so they can take advantage of slice
    
threading. The ticket which this error was added for (#4408) no
    
longer segfaults after removing this error (as the bug was likely
    
fixed more properly elsewhere).
