Do you want to encode videos on your phone into different formats, trim videos, or extract audio? Are you looking for a free solution which will not take your information?

Video Transcoder is an application which uses the open source program FFmpeg to transcode video files from one format to another. By selecting the video to process, details for the video are provided and the desired settings can be configured.

The following media containers are supported: Avi, Flv, Gif, Matroska, Mp3, Mp4, Ogg, Opus, WebM. Additionally, these are the supported video codecs: H.264, MPEG-1, MPEG-2, MPEG-4, VP8, VP9, Xvid.

The application requires very few permissions, and never attempts to access the Internet.

Building

To build, use the gradle wrapper scripts provided in the top level directory of the project. The following will compile the application and run all unit tests:

GNU/Linux, OSX, UNIX:

./gradlew build

Windows:

./gradlew.bat build

Note from Developer

The developer is currently on hiatus from the project. Questions and pull requests may not be looked at for some time. Apologies in advance.

    Eg, like SendReduced does.

    Workflow:

    • gallery app
    • open video
    • share...to transcoder
    • process with last used ( #41 ) or some other profile ( #40 )
    • show share widget again
    • choose some app eg, chat app

  • Cannot load video from extern sd card on Android 7.1

    Cannot load video from extern sd card on Android 7.1

    Error message: Failed to resolve the location of media file It seems like it's nessesary to use the media framework API for loading from extern sd card. If ffmpeg needs direct access to the file and can't use the framework, maybe your app could automatically copy the video to intern storage for editing.

    [Q] which x264 preset is used?

    Quick question, which x264 preset is currently being used? The default medium one?
    According to newest findings the "faster" preset seems to offer the best speed<->quality balance:
    https://streaminglearningcenter.com/blogs/saving-encoding-adjust-encoding-configuration-increase-capacity.html
    It is found to be 70% faster than the default with quality difference that should not be perceptible
    Maybe you could make sure it is the one this app uses?

  • Add custom resolution and FPS option

    Add custom resolution and FPS option

    So I just saw that your app is using wrong 4K format, I thought it would be nice to report my opinions.

    First of all thank you for making such a good application.

    My current requests will be divided into issues so that you can easily close the ones you accomplish.

    You really must remove uncommon resolutions in encoding such as 800x600 and add their corresponding xxP end of the title.

  • No error, just doesn't encode after starting. I suspect it can't write to SDCard?

    No error, just doesn't encode after starting. I suspect it can't write to SDCard?

    So I was trying to encode a clip that's on my SDCard so I could convert it into a GIF in another app, but it would not give me an error message even after several minutes. I'm only guessing that it can't write to the card; only has read access. Is it possible to add an output directory so I could point the new file to internal storage in the next release?

  • Make FilePicker scroll faster for big folders

    Make FilePicker scroll faster for big folders

    Hi,

    thanks for this nice project — and the best and only usable FOSS transcoder for android :+1: .

    On Android phones, people often don’t move pictures and videos around. Thus, the Camera/DCIM-folder (or whatever it’s called on your device), is often crowded, with thousands of pictures and (a little less) videos. Especially since videos come at the end of that list (VID_* > IMG_*), it’s arduous to scroll through ~8000 files to pick your most recent video.

    It’d be great if this could somehow be improved. I have looked over the source quickly, and found you use the excellent NoNonsense-FilePicker. There’s an issue over at their tracker, for exactly this behavior: https://github.com/spacecowboy/NoNonsense-FilePicker/issues/87 The suggested resolution to use https://github.com/timusus/RecyclerView-FastScroll looks quite nice IMO. If you scroll down in the FilePicker issue, you’ll find they even added this in their example code.

    It’d be great if the already very useful Video-Transcoder could be made even more accessible and convenient with this addition.

    Thanks and Best Regards -Dario

  • Using as audio transcoder: allow mp3 m4a ogg files as input

    Using as audio transcoder: allow mp3 m4a ogg files as input

    video-transcoder and ffmpeg can also transcode audio-only files.

    For video-transcoder i have to rename the audio file "someAudio.m4a" to "someAudio.m4a.avi" to allow converting to mp3.

    I would be nice if video-transcoder also accept audio file names mp3 m4a ogg

    Request for acceptance of the Italian translation on Transifex

    I have seen from a previous closed issue that not always the translation requests are forwarded. I already have the translated XML ready, but I'm too much of a lazy noob to do a pull request on GitHub. P.S. This string seems missing from other translated XMLs: <string name=""invalidMediaFile"">The Selected media file is invalid or not supported

    [question/bug] Android 11 partial incompatibility

    Hello.

    Will this great and very useful appl go back into development ? Or at least, will someone have the skills and the goodwill to make fully compatible android 11 at least, what already exists?

    The first very annoying bug noticed is that it seems impossible to access the SD card. Is this the case or did I miss something?

    In the immediate future, any advice for a quality and non-intrusive android video converter, compatible with android 11, would be very useful to me.

    Thanks in advance. Best regards

  • REQUEST: Add

    REQUEST: Add "copy" options for audio and video codecs

    Many times only the audio or video codecs need to be transcoded and not both. Or the file needs to be remuxed into a different container. It would be helpful if you could copy the existing audio, video, or both.

    Process forking options. Gradle will run all tests in a single forked VM by default. This can be problematic if there are a lot of tests or some very memory-hungry ones. We can fork a new test VM after a certain number of tests have run by setting forkEvery.

    This is release v0.1 of Video Transcoder. It provides:

    • Ability to select a video file to process.
    • Pre-populates video/audio settings with that of the selected video file.
    • Ability to change video/audio settings using several pre-selected options.
    • Ability to transcode the selected video to the same or different video format or audio format.
    • Ability to change the start and ending times of the resulting video or audio file.
    • Ability to cancel an in-progress file being encoded.

    Note that this project does not work on recent versions of Android running on x86.

    This project is a bit rough presently. It may work to transcode a file, but it is not yet helpful in guiding a user to a specific goal. For example, if a user wanted to encode a video to be smaller, no guidance is given on how to accomplish that.
