  • CANNOT LINK EXECUTEABLE ffmpeg android

    18 décembre 2019, par eilon marinberg

    I am building an app for android that uses FFMPEG native code, and whenever I run the FFMPEG command I am getting an error that says :

    V/onFailure : CANNOT LINK EXECUTABLE "/data/user/0/com.android.pprojecct/files/ffmpeg" : "/data/data/com.android.pproject/files/ffmpeg" has text relocations

    I am using an implemented lib I found :

    implementation 'nl.bravobit:android-ffmpeg:1.1.7'

  • Blackmagic Deck Link Quad 2 and Multiple Streams with FFmpeg

    23 juin 2018, par SpacePirateRob

    I am trying to accomplish streaming videos from 4 or more feeds on a local display from a DeckLink Quad 2 using FFmpeg as my transcoder. I can play two different videos (I only have two sources I can use simultaneously at my desk) fine, but struggle with connecting them into a single video if they are both on the DeckLink. The code I have for a single stream run as a .bat is below...

    ffplay  -video_size 1280x720 -framerate 60 -pixel_format uyvy422 -f dshow -i video="Decklink Video Capture" \ pause

    Reading most forums it would seem that sticking them together with a complex filter should work, as such :

    ffmpeg -video_size 1280x720 -pixel_format uyvy422 -framerate 60 -vsync drop -f dshow -rtbufsize 150M -i video="Decklink Video Capture (5)" -i video="Decklink Video Capture" -i video="Decklink Video Capture (5)" -i video="Decklink Video Capture" -an -filter_complex "[0:v][1:v]hstack[t]; [2:v][3:v]hstack[b]; [t][b]vstack" -c:v libx264 -preset ultrafast -f mpegts pipe: | ffplay pipe: -vf scale=1280:720 \ pause

    And, with two videos not from the DeckLink (i.e. DeckLink and file), it does work ! But with both coming from the DeckLink I get the following in the console :

    Input #0, dshow, from 'video=Decklink Video Capture (5)':0B f=0/0
    
  Duration: N/A, start: 71582788.354257, bitrate: N/A
    
    Stream #0:0: Video: rawvideo (HDYC / 0x43594448), uyvy422(tv), 1280x720, 60 fps, 60 tbr, 10000k tbn, 10000k tbc
    
video=Decklink Video Capture: No such file or directory
    
pipe:: Invalid data found when processing inputKB sq=    0B f=0/0

    And that stream works running on its own too. So my optimistic concern is just that I’m using the wrong naming scheme ; my only other idea is that I can’t read two streams from the DeckLink card simultaneously (though I feel like I’ve read I can). Another concern is introduced here too : one of my streams does not run with frame rate set to 60fps, I need to set it to 59.94fps to work, otherwise it is a black screen.

    Would I need to split these into multiple processed to run each stream simultaneously, save them to a temporary file or a pipeline, then combine them in another stream to display ? I am concerned about the latency that program would introduce though. Thank you in advance !

    avfilter/video : pick sar from link

    It should not be needed for each filter that sets sample aspect ratio
    
to set it explicitly also for each and every frame, instead that is
    
automatically done in get_buffer call.
