  • Unable to build ffmpeg for ExoPlayer

    3 janvier 2021, par Steven Rõgrê

    I'm trying to add support for multiple audio formats in my app but cannot seem to build the ffmpeg extension on my mac.

    


    I followed this readme :https://github.com/google/ExoPlayer/tree/dev-v2/extensions/ffmpeg

    


    But I keep getting this error :

    


    mac/NDKK>/toolchains/llvm/prebuilt/darwin-x86_64/bin/armv7a-linux-androideabi16-clang is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.


    


    I tried NDK20 as well as NDK19 but the same error, so need help from someone who is familiar with this.

    


    I'm trying to build the following formats "aac ac3 eac3 dca".

    


    Edit : Here's the full commands and logs :

  • How to mux a raw vp8 to webm with ffmpeg and demux webm to vp8 ?

    23 mai 2017, par Edward_zhuo

    I have a raw vp8 data grabbed from web,and I can not mux it to webm. I use FFmpeg’s latest program, it supports libvpx. I don’t know what’s wrong. Also I can’t demux a webm file to ".vp8" file.

  • passing additional values to s3 event notification for lambda consumption

    8 septembre 2017, par user1790300

    I have to write code in react-native that allows a user to upload videos to amazon s3 to be transcoded for consumption by various devices. For the processing after the upload occurs ; I am reviewing two approaches :

    1) I can use Lambda with ffmpeg to handle the transcoding immediately after the uploading occurs (my fear here would be the amount of time required to transcode the videos and the effect on pricing if it takes a considerable amount of time).

    2) I can have s3 pass an sns message to a rest api after the created event occurs and the rest api generate a rabbitmq message that will be processed by worker that will perform the transcoding using ffmpeg.

    Option 1) seems to be the preferable option based on a completion time perspective. How concerned should I be with using 1) considering how long video transcoding might take as opposed to option 2) ?

    Also, regardless, I need a way to pass additional parameters to lambda or along the sns messaging that would allow me to somehow associate the user who uploaded the video with their account. Is there a way to pass additional text-based values to s3 to pass along to lambda or along sns when the upload completes, as a caveat I plan to upload the video directly to s3 using the rest layer(found this answer here : http://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html#RESTObjectPUT-responses-examples) ?
