  • Convert WAV to AIFF with ffmpeg

    12 novembre 2016, par Arete

    How can I convert a wav file to an AIF file with ffmpeg ?

    I need to make various files one in 16 Bit, one in 24 bit and one in 32 Bit.

    I also need to make different sample rates. E.g one in 176,400 kHz and one in 44,100 kHz.

    I know ffmpeg -i input-file.wav output-file.aif will convert the file but I am not sure about the rest.

    https://www.ffmpeg.org/general.html#Audio-Codecs says ffmpeg supports AIFF but there is no documentation on the AIFF encoding : https://en.wikipedia.org/wiki/Audio_Interchange_File_Format#AIFF-C_common_compression_types

  • Capturing video over USB/HDMI/Thunderbolt

    12 novembre 2016, par Yatko

    Looking for a solution for capturing video over USB/HDMI/Thunderbolt from a digital output (e.g. digital camera) to a computer, Mac and/or Windows.

    The goal is to have an URL to a real-time video stream (e.g. IP/PATH/ ?.mp4) that we can further process/transcode/send to a media server.

    I’m looking for tips and ideas -similar to the method below-, maybe someone met a new project that’s focusing on capture-cards and devices, that does’n need a custom FFmpeg build. Something different.

    • we can capture the HDMI stream form a GoPro, using a Blackmagic Intensity Shuttle and DeckLink SDK with custom FFmpeg build using --extra-cflags and --extra-ldflags and the rest is straightforward

    Is there any tool, open-source project, something that’s made for this purpose ? Maybe something that also supports the Elgato Game Capture HD60 as well ? Any experimental projects for capturing and processing the incoming video over USB/HDMI/Thunderbolt ?

    The ultimate goal is live streaming to Wowza, using Cameleon live and a Sony Alpha a7S.

  • FFMPEG detect color bars and tone in video

    23 novembre 2016, par Chris Harvey

    I am trying to detect if a video has any valid content or is just the standard broadcasting bars & tone. So far I’ve looked at this question : http://superuser.com/questions/1036449/detect-color-bars-ffmpeg/1036478#1036478
    which generates bars & tone from the first frame and then compares that against the rest of the stream but in my case I need to run the ffmpeg command within a folder that only has one file that has already been found by my python script.

    Is it possible to use ffmpeg’s blend=difference to check that a short bars & tone clip is a subclip of one of my video files ? I’m thinking of this in the same way you can check if a string is within a string, or is there a better way to check for bars that I’m not thinking of ?

    Thanks !
