  • multichannel (dolby digital, DTS, ecc.) delay difference on original master

    17 janvier 2017, par esposito

    I have different flac files with 6/8 channels (this is the audio of movie) and I need to mix with ffmpeg part of rear channels with front channels and sometimes viceversa.

    There is no problem do it the operation work with an automate software.

    But I’am sure there is a phase difference beetween front channels and rear channels and I like to add a delay to compensate this difference (when I listen it is clear there is a phase offset and this degrade the result).

    I don’t have an idea about how many milliseconds I need to add to compensate and what channel and if the difference is negative or positive.

    Someone can help me please to understand approximately what are the range of delay for each channel (a table is very useful) ?

    Thank you !!

  • net core and video transcoding on aws lambda

    14 septembre 2022, par user1765862

    I'm looking for a solution to :

    


      

    1. upload video to s3 bucket

      2. 


    2. after video upload an aws lambda function will be triggered

      3. 


    3. lambda function will use ffmpeg layer in order to transcode video (mainly cropping with other functionalities)

      4. 


    4. save result (transcoded video into s3 bucket)

      5. 


    


    My language of choice inside lambda is c# and net core runtime.

    


    I have found various resources for video manipulation with aws ffmpeg layer using lambda function but no examples in net core lambda.

    


    My question is :

    


    


    Can I use existing FFmpeg/FFprobe Lambda Layer for Amazon Linux such
as this one with lambda function written in c# and .net core ?

    


    


    Another question :

    


    


    Would you suggest Amazon Elastic Transcoder as a better choice with
lambda function .net core integration ?

    


    


  • Unknown input : 'dshow' [on hold]

    2 avril 2018, par Santa Maria

    Я ввела команду ffmpeg -list_devices true -f dshow -i dummy, но нормального результата не было. FFmpeg выдаёт ошибку unknown input: 'dshow'. Что делать ? Прошу прощения, если вопрос глупый
