  • Errors when use mps in NVDEC ?

    4 avril 2019, par johnsondeng

    I use ffmpeg compiled with cuda, support nvdec to decode h264 in gpu devices. MPS(https://docs.nvidia.com/deploy/mps/index.html) can share context with different processes, and this can use less gpu storage when use multi-process to decode h264 stream. But when I use ffmpeg in this mode, error got like this.

    Input #0, mpeg, from '/data/yt_traffic/media/nianjianbiao.mp4':
    
Duration: 00:16:57.97, start: 7833.134000, bitrate: 4219 kb/s
    
Stream #0:0[0x1e0]: Video: h264 (High), yuv420p(progressive), 1920x1080, 25 fps, 25 tbr, 90k tbn, 50 tbc
    
File '1.yuv' already exists. Overwrite ? [y/N] y
    
[AVHWDeviceContext @ 0x4444840] Could not initialize the CUDA driver API
    
Stream mapping:
    
Stream #0:0 -> #0:0 (h264 (h264_cuvid) -> rawvideo (native))
    
Error while opening decoder for input stream #0:0 : Unknown error occurred

    But when mps is shutdown, ffmpeg works fine. Anyone can help ?

  • Android and JNI, pipe data to FFmpeg

    2 décembre 2014, par William Seemann

    I’m trying to create a metadata retriever based on FFmpeg. Since raw Android application resources are often only accessible using a file descriptor I need a way to pipe this data to FFmpeg via JNI. I know FFmpeg supports a "pipe" protocol :

    UNIX pipe access protocol.
    

    
Allow to read and write from UNIX pipes.
    

    
The accepted syntax is: 
    

    
    pipe:[number]
    

    
number is the number corresponding to the file descriptor of the pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr). If number is not specified, by default the stdout file descriptor will be used for writing, stdin for reading.
    

    
For example: cat test.wav | ffmpeg -i pipe:0

    My question is, how do I programmatically emulate cat test.wav | ffmpeg -i pipe:0 using JNI and avformat_open_input using a FileDescriptor ? Is this possible ?

  • RFC 4175 support in ffmpeg ?

    28 novembre 2018, par Morix Dev

    As of today, is RFC 4175 (aka SMPTE 2110-20) currently supported in the released version of ffmpeg (4.1) ?

    Surfing the web I am only able to find these two references :

    But it is not clear to me if it has been merged into the released version or not...

    If so, are there some examples of ffmpeg / ffplay command lines for testing that ?
