No Video With Supported Format
For a full HD video (1920×1080 px), the best video format for YouTube, according to the platform, is the MP4 file type in combination with an H.264 codec, 15-20 Mbps, a standard aspect ratio of 16:9, and audio codec AAC-LC. A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size. A video file normally consists of a container (e.g. In the Matroska format) containing video data in a video coding format (e.g. VP9 ) alongside audio data in an audio.
A video file format is a type of file format for storing digital video data on a computer system. Video is almost always stored using lossy compression to reduce the file size.
A video file normally consists of a container (e.g. in the Matroska format) containing video data in a video coding format (e.g. VP9) alongside audio data in an audio coding format (e.g. Opus). The container can also contain synchronization information, subtitles, and metadata such as title. A standardized (or in some cases de facto standard) video file type such as .webm is a profile specified by a restriction on which container format and which video and audio compression formats are allowed.
The coded video and audio inside a video file container (i.e. not headers, footers, and metadata) is called the essence. A program (or hardware) which can decode compressed video or audio is called a codec; playing or encoding a video file will sometimes require the user to install a codec library corresponding to the type of video and audio coding used in the file.
Good design normally dictates that a file extension enables the user to derive which program will open the file from the file extension. That is the case with some video file formats, such as WebM (.webm), Windows Media Video (.wmv), Flash Video (.flv), and Ogg Video (.ogv), each of which can only contain a few well-defined subtypes of video and audio coding formats, making it relatively easy to know which codec will play the file. In contrast to that, some very general-purpose container types like AVI (.avi) and QuickTime (.mov) can contain video and audio in almost any format, and have file extensions named after the container type, making it very hard for the end user to use the file extension to derive which codec or program to use to play the files.
The free softwareFFmpeg project's libraries have very wide support for encoding and decoding video file formats. Need for speed underground 2 unlock everything mod. For example, Google uses ffmpeg to support a wide range of upload video formats for YouTube.[1] One widely used media player using the ffmpeg libraries is the free software VLC media player, which can play most video files that end users will encounter.
List of video file formats[edit]
| Name | File extension(s) | Container format | Video coding format(s) | Audio coding format(s) | Notes |
|---|---|---|---|---|---|
| WebM | .webm | Matroska | VP8, VP9, AV1 | Vorbis, Opus | Royalty-free format created for HTML5 video. |
| Matroska | .mkv | Matroska | any | any | |
| Flash Video (FLV) | .flv | FLV | VP6, Sorenson Spark, Screen video, Screen video 2, H.264 | MP3, ADPCM, Nellymoser, Speex, AAC | Use of the H.264 and AAC compression formats in the FLV file format has some limitations and authors of Flash Player strongly encourage everyone to embrace the new standard F4V file format[2] de facto standard for web-based streaming video (over RTMP). |
| F4V | .flv | MPEG-4 Part 12 | H.264 | MP3, AAC | Replacement for FLV. |
| Vob | .vob | VOB | H.262/MPEG-2 Part 2 or MPEG-1 Part 2 | PCM, DTS, MPEG-1, Audio Layer II (MP2), or Dolby Digital (AC-3) | Files in VOB format have .vob filename extension and are typically stored in the VIDEO_TS folder at the root of a DVD. The VOB format is based on the MPEG program stream format. |
| Ogg Video | .ogv, .ogg | Ogg | Theora, Dirac | Vorbis, FLAC | |
| Dirac | .drc | ? | Dirac | ? | |
| GIF | .gif | N/A | N/A | none | Simple animation, inefficient compression, no sound, widely supported |
| Video alternative to GIF | .gifv | HTML | any | none | Not standardized, and not a real video file in the classical meaning since it merely references the real video file (e.g. a .webm file), which has to exist separately elsewhere. A .gifv 'file' is simply a HTML webpage which includes a HTML5 video tag, where the video has no sound. As there were large communities online which create art using the medium of short soundless videos in GIF format, GIFV was created as a functionally similar replacement with vastly smaller filesizes than the inefficient GIF format. |

When defining the formats that ExoPlayer supports, it’s important to note that“media formats” are defined at multiple levels. From the lowest level to thehighest, these are:
- The format of the individual media samples (e.g., a frame of video or a frameof audio). These are sample formats. Note that a typical video file willcontain media in at least two sample formats; one for video (e.g., H.264) andone for audio (e.g., AAC).
- The format of the container that houses the media samples and associatedmetadata. These are container formats. A media file has a single containerformat (e.g., MP4), which is commonly indicated by the file extension. Notethat for some audio only formats (e.g., MP3), the sample and container formatsmay be the same.
- Adaptive streaming technologies such as DASH, SmoothStreaming and HLS. Theseare not media formats as such, however it’s still necessary to define whatlevel of support ExoPlayer provides.
The following sections define ExoPlayer’s support at each level, from highest tolowest. The last two sections describe support for standalone subtitle formatsand HDR video playback.
Adaptive streaming
DASH
ExoPlayer supports DASH with multiple container formats. Media streams must bedemuxed, meaning that video, audio and text must be defined in distinctAdaptationSet elements in the DASH manifest (CEA-608 is an exception asdescribed in the table below). The contained audio and video sample formats mustalso be supported (see thesample formats section for details).

Progressive container formats
Streams in the following container formats can be played directly by ExoPlayer.The contained audio and video sample formats must also be supported (see thesample formats section for details).
| Container format | Supported | Comments |
|---|---|---|
| MP4 | YES | |
| M4A | YES | |
| FMP4 | YES | |
| WebM | YES | |
| Matroska | YES | |
| MP3 | YES | Some streams only seekable using constant bitrate seeking** |
| Ogg | YES | Containing Vorbis, Opus and FLAC |
| WAV | YES | |
| MPEG-TS | YES | |
| MPEG-PS | YES | |
| FLV | YES | Not seekable* |
| ADTS (AAC) | YES | Only seekable using constant bitrate seeking** |
| FLAC | YES | Using the FLAC extension or the FLAC extractor in the core library*** |
| AMR | YES | Only seekable using constant bitrate seeking** |
| JPEG motion photo | YES | Only the MP4 content is extracted |
* Seeking is unsupported because the container does not provide metadata (e.g.,a sample index) to allow a media player to perform a seek in an efficient way.If seeking is required, we suggest using a more appropriate container format.
** These extractors have FLAG_ENABLE_CONSTANT_BITRATE_SEEKING flags forenabling approximate seeking using a constant bitrate assumption. Thisfunctionality is not enabled by default. The simplest way to enable thisfunctionality for all extractors that support it is to useDefaultExtractorsFactory.setConstantBitrateSeekingEnabled, as describedhere.
*** The FLAC extension extractor outputs raw audio, which can be handledby the framework on all API levels. The core library FLAC extractor outputsFLAC audio frames and so relies on having a FLAC decoder (e.g., a MediaCodecdecoder that handles FLAC (required from API level 27), or theFFmpeg extension with FLAC enabled). The DefaultExtractorsFactory uses theextension extractor if the application was built with the FLAC extension.Otherwise, it uses the core library extractor.
Sample formats
Fix Video Format Not Supported
By default ExoPlayer uses Android’s platform decoders. Hence the supportedsample formats depend on the underlying platform rather than on ExoPlayer.Sample formats supported by Android devices are documentedhere.Note that individual devices may support additional formats beyond those listed. Vengeance torrent samples.
In addition to Android’s platform decoders, ExoPlayer can also make use ofsoftware decoder extensions. These must be manually built and included inprojects that wish to make use of them. We currently provide software decoderextensions forAV1,VP9,FLAC,Opus andFFmpeg.
FFmpeg extension
The FFmpeg extension supportsdecoding a variety of different audio sample formats. You can choose whichdecoders to include when building the extension, as documented in theextension’s README.md. Thefollowing table provides a mapping from audio sample format to the correspondingFFmpeg decoder name.
| Sample format | Decoder name(s) |
|---|---|
| Vorbis | vorbis |
| Opus | opus |
| FLAC | flac |
| ALAC | alac |
| PCM μ-law | pcm_mulaw |
| PCM A-law | pcm_alaw |
| MP1, MP2, MP3 | mp3 |
| AMR-NB | amrnb |
| AMR-WB | amrwb |
| AAC | aac |
| AC-3 | ac3 |
| E-AC-3 | eac3 |
| DTS, DTS-HD | dca |
| TrueHD | mlp truehd |

Standalone subtitle formats
ExoPlayer supports standalone subtitle files in a variety of formats. Subtitlefiles can be side-loaded as described on the Media source page.
| Container format | Supported | MIME type |
|---|---|---|
| WebVTT | YES | MimeTypes.TEXT_VTT |
| TTML / SMPTE-TT | YES | MimeTypes.APPLICATION_TTML |
| SubRip | YES | MimeTypes.APPLICATION_SUBRIP |
| SubStationAlpha (SSA/ASS) | YES | MimeTypes.TEXT_SSA |
No Video With Supported Format Or Mime Type
HDR video playback
ExoPlayer handles extracting high dynamic range (HDR) video in variouscontainers, including Dolby Vision in MP4 and HDR10+ in Matroska/WebM. Decodingand displaying HDR content depends on support from the Android platform anddevice. SeeHDR Video Playbackto learn about checking for HDR decoding/display capabilities and limitations ofHDR support across Android versions.
No Video With Supported Format
When playing an HDR stream that requires support for a particular codec profile,ExoPlayer’s default MediaCodec selector will pick a decoder that supports thatprofile (if available), even if another decoder for the same MIME type thatdoesn’t support that profile appears higher up the codec list. This can resultin selecting a software decoder in cases where the stream exceeds thecapabilities of a hardware decoder for the same MIME type.
