Updated package description.In most video workflows there will be a transcoding server or serverless cloud function, that encodes the video into various resolutions and bitrates for optimal viewing in all devices and network speeds.

This will save considerable costs, but will put the burden of encoding videos on the clients. This is the software used to encode the video into the H.

There are many other codecs, but seeing as the H. A method to encode the video into multiple bitrates of varying qualityand each bitrate into many small chunks.

The streaming protocol will allow the player to choose which quality the next chunk will be, according to network speed. So if you go from WiFi to cellular data, your player can adapt the bitrate accordingly, without reloading the entire video. In HLS, the video is split to chunks in the form of. Here we'll use the min-gpl-lts package, as it contains the x codec, and can be used in release builds. And in your Podfile replace this line:.

Now we need to configure public read access to the video files, so that we can access them without a token see comment. We check the result code to ensure the operation finished successfully.

Now for the actual video encoding. For this example I used the parameters from this excellent HLS tutorial. This will generate multiple fileSequence.

It will also generate a master. Note: This is a simple encoding example, but the options are endless. Now that encoding is done, we need to upload the files to Cloud Storage. Uploading to Cloud Storage is quite straightforward. We get a StorageReference into the path where we want the file to be stored with FirebaseStorage. Then we call ref. When the uploading is done, the await taskSnapshot.

Now we need to go over all the generated HLS file. But before we do, we need to fix them so that they point to the correct urls relative to their place in Cloud Storage. This is how the. This is the relative path to the. But when we upload this to a folder, it's missing the folder name from the URL.

Also, you should use a stream specifier with the -c option, such as -c:v for video, and -c:a for the audio.

The exception is when you want to stream copy all stream types, but since you're filtering you can't do that filtering requires encoding.

Awesome this works for me, Thanks so much. I was wondering, Is there a way I can centre crop the videos? For example, I want a vertical and horizontally centred video of x, Is this possible?

Or do I have to manually specify it? See the crop filter documentation for more info. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

I have been trying to use ffmpeg to compress a videos file size so I can upload to firebase storage. I've ran the code on windows cmd and it works. But when i run it on flutter the quality of the video is terrible.

I have also specified many values for the -crf param but the output videos quality and file size are always the same.

I had to change the package to video as the execution would fail on the default import as it could not find the -crf param. Am I doing something wrong with the execution arguments or is the import I'm using not the correct package.

Sorry I'm very new to ffmpeg. If you use a GPL licensed package like min-gplhttps-gpl or full-gpl then your output video will be encoded with x and have better quality.
