  • Can't Titan Black use NVENC ?

    13 mars 2016, par SPWW

    I compiled FFMPEG with —enable-nvenc and want to encode with NVENC encoder, but I got this error message when running ffmpeg.

    [nvenc_h264 @ 0x8ed020] 4 CUDA capable devices found

    I have titan black gpu and as the official document said it should be supported.

    my nvenc-sdk version is 5.0

    and the nvidia-smi info is listed below.

  • DASH package (mpd) I made freezes after raising the onratechange event

    7 mars 2016, par Nick Birke

    I am trying to created an adaptive stream from an mp4 file. I have a decent amount of experience at doing streaming, and have successfully implemented smooth streaming via Silverlight. We want a solution for everything that works in HTML5. I am pursuing DASH. So here are the steps I take...

    1. Resample the mp4 to different sizes using ffmpeg.
    2. Ensure the files are properly fragmented using Bento4s mp4Fragment utility.
    3. Create the DASH mpd file and associated segments using Bento4s mp4dash utility.

    I have done a lot of work to learn each of these utilities and create a process that gets to output that I think will work. To create reliable DASH artifacts. But it seems I am doing something wrong. Here are examples of command lines I run.

    For step one I create three different files... for three different rates and sizes... (these may not be the exact command lines, they are from old notes... but the parameter values are the ones I am using for sure)

    ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 1500k -maxrate 1500k -bufsize 1000k -vf "scale=-1:720" C:\_SIMULATED_SHARE_C\ff\output\outputfile720.mp4
    

    
ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 800k -maxrate 800k -bufsize 500k -vf "scale=-1:540" C:\_SIMULATED_SHARE_C\ff\output\outputfile540.mp4
    

    
ffmpeg -y -i C:\_SIMULATED_SHARE_C\ff\big_buck_bunny.mp4 -c:v libx264 -x264opts keyint=24:min-keyint=24:no-scenecut -b:v 400k -maxrate 400k -bufsize 400k -vf "scale=-1:360" C:\_SIMULATED_SHARE_C\ff\output\outputfile360.mp4

    So that gives you the three files that need to be fragmented. So I fragment them using the mp4fragment utility from Bento4. That command line is simple so I will not offer an example.

    The I use Bento4s mp4dash to create the dash. Something like this...

    "E:\\_INSTALL\\Bento4\\Bento4-SDK-1-4-3-607.x86-microsoft-win32-vs2010\\Bento4-SDK-1-4-3-607.x86-microsoft-win32-vs2010\\bin\\mp4dash.exe --mpd-name=\"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\dash\\something.mpd\" -f -o \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\dash\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny360f.mp4\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny540f.mp4\" \"\\\\d9fqt52\\_SIMULATED_SHARE_C\\ff\\output\\bunny720f.mp4\" "

    This runs ok. And creates the mpd file, an audio folder with segment files, an a video folder with 3 folders each with the segment files.

    I am able to configure IIS to play the mpd ok. As well as the segement files. The video plays fine... and then it stops. It freezes between 50 and 60 seconds. Right before it freezes I can confirm that the onratechange event of the HTML5 video tag is raised. This is an event that is raised with the rate of play is changed. I do nothing to change this it just happens.

    The actual video in question is about 1hr long. Also I am using the dash.js library as a player.

    If you can identify any components or specifics I should change please let me know !
