ffmpeg – Utilizza filter in android

Sto cercando di utilizzare il filter del film nel mio progetto android con ffmpeg. Io uso una forchetta del progetto guardiano: Cheers-dev

Utilizza una versione recente di ffmpeg (~ 15 giorni di atm). Ho aggiunto l'opzione --enable-filter=movie per triggersre il filter.

  • Emulatore Android chiudere utilizzando telnet tramite script di appium
  • Aggiungi nuovo numero di elementi all'icona sul button - Android
  • Android DevicePolicyManager locknow () non funziona in Lollipop
  • Vedere l'attività Android recente eseguita dall'utente
  • Jenkins non crea nuovo emulatore Android: Imansible analizzare il file di configuration AVD
  • Come utilizzare dispatchTouchEvent?
  • Io uso questa linea di command nel mio progetto android:

     ffmpeg -i input.mp4 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" -strict -2 outputvideo.mp4 

    Funziona perfettamente con la mia versione desktop su Debian Wheezy. Ma è imansible far funzionare il mio Android. Tutti gli altri comandi funzionano.

    Qui l'errore quando non riesce: No such filter: 'movie' .

    Ho anche provato con l'opzione -filter_complex con un errore un po 'diverso:

     $ ffmpeg -y -loglevel debug -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out]" -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4 ffmpeg version N-58429-gccdfa3e Copyright (c) 2000-2013 the FFmpeg developers built on Dec 10 2013 01:12:39 with gcc 4.4.3 (GCC) configuration: --arch=arm --cpu=cortex-a8 --target-os=linux --enable-runtime-cpudetect --prefix=/data/data/info.guardianproject.ffmpeg/app_opt --enable-pic --disable-shared --enable-static --cross-prefix=/opt/android/ndk-r8/toolchains/arm-linux-androidabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androidabi- --sysroot=/opt/android/ndk-r8/platforms/android-14/arch-arm --extra-cflags='-I../x264 -I/Android/cheers/android-ffmpeg/data/data/info.guardianproject.ffmpeg/app_opt/include -mfloat-abi=softfp -mfpu=neon' --extra-ldflags='-L../x264 -L/Android/cheers/android-ffmpeg/data/data/info.guardianproject.ffmpeg/app_opt/lib' --enable-version3 --enable-gpl --enable-yasm --enable-decoders --enable-encoders --enable-muxers --enable-demuxers --enable-parsers --enable-protocols --enable-filter=movie --enable-avresample --enable-libvorbis --disable-indevs --enable-indev=lavfi libavutil 52. 54.100 / 52. 54.100 libavcodec 55. 44.100 / 55. 44.100 libavformat 55. 21.101 / 55. 21.101 libavdevice 55. 5.100 / 55. 5.100 libavfilter 3. 91.100 / 3. 91.100 libavresample 1. 1. 0 / 1. 1. 0 libswscale 2. 5.101 / 2. 5.101 libswresample 0. 17.104 / 0. 17.104 libpostproc 52. 3.100 / 52. 3.100 Splitting the commandline.

    L'output è migliore di quella precedente ma penso che mi manca qualcosa.

    SOLUZIONE : ho rimosso la citazione dall'argomento filter_complex e ha funzionato.

    Ecco il command di funzionamento:

     $ ffmpeg -y -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex [0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out] -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4 

  • Android aggiunge l'annuncio (admob) alla schermata OPENGL-ES
  • il segnale di notifica locale di cordova non funziona in ios e andorid
  • Recuperare il text da un object RemoteViews
  • Come posso impostare la dimensione del layout e del text in DP all'interno del programma?
  • voglio aprire un'image in un'altra attività quando faccio clic sull'elemento nell'elenco
  • Imansible ignorare i methods della class LocationListener

    Per risolvere il mio problema ho rimosso la double citazione attorno all'argomento filter_complex. Ecco il command di funzionamento:

     $ ffmpeg -y -i /storage/sdcard0/test/hsgjr_export.mp4 -i /storage/sdcard0/test/watermark.png -filter_complex [0:v][1:v]overlay=main_w-overlay_w-10:main_h-overlay_h-10[out] -map [out] -map 0:a -codec:a copy /storage/sdcard0/test/hsgjr_watermark.mp4
