Is there any way to get MPEG-4 video fils’s profile-code using standard Android API?
Sample profile-codes are: baseline
, main
, high
and so on.
I don’t want to include ffmpeg
binary in the android app just to get this information.
I found reference of list of profiles in MediaCodecInfo.CodecProfileLevel class. Can any body confirm if this is the one I should be using?
Here is an example screenshot of video info taken from MX Player app
- UPDATE #1: I looked into MX Player app, looks like they use
ffmpeg
binary, so I can safely say they use that to extractprofile-code
. - UPDATE #2: I also looked into ExoPlayer v1 APIs, they also don’t seems to have specific API to get this info.
Profile code can be found using MediaExtractor
Based on API documentation it seems that the encoding profile-code is only available from API level 24 (Nougat) and up.
Here is method I wrote to extract the profile code, feel free to modify to meet your need.
/**
* Get video profile-code from video file.
*
* @param videoFilePath Path of the video file.
* @return One of predefined AVC profiles from {@link MediaCodecInfo.CodecProfileLevel} when found, or {@code -1} if
* Android API level does not support extracting profile data.
*/
@TargetApi(21)
public int getVideoEncodingProfile(final String videoFilePath) {
int videoProfileCode = -1;
File inputFile = new File(videoFilePath);
if (!inputFile.canRead()) {
throw new RuntimeException("Unable to read " + inputFile);
}
MediaExtractor mediaExtractor = new MediaExtractor();
// Initialize MediaExtractor and configure/extract video information
try {
mediaExtractor.setDataSource(inputFile.toString());
} catch (IOException e) {
Log.e(TAG, "Unable to set MediaExtractor source.", e);
throw new RuntimeException("Unable to set source.");
}
MediaFormat videoMediaFormat = findVideoMediaFormat(mediaExtractor);
// MediaCodecInfo.CodecProfileLevel of the video track
if (videoMediaFormat != null && videoMediaFormat.containsKey(MediaFormat.KEY_PROFILE)) {
videoProfileCode = videoMediaFormat.getInteger(MediaFormat.KEY_PROFILE);
} else {
// Current API level does not support encoding profile information.
Log.w(TAG, "Video profile code is not supported by current API level.");
}
mediaExtractor.release();
mediaExtractor = null;
return videoProfileCode;
}
/**
* Find video MediaFormat from MediaExtractor.
*
* @param mediaExtractor The MediaExtractor which is used to find video track.
* @return MediaFormat for video track, or {@code null} when video track is not found.
*/
private MediaFormat findVideoMediaFormat(final MediaExtractor mediaExtractor) {
MediaFormat videoTrackMediaFormat = null;
int totalTracks = mediaExtractor.getTrackCount();
for (int i = 0; i < totalTracks; i++) {
MediaFormat trackFormat = mediaExtractor.getTrackFormat(i);
if ((trackFormat.containsKey(MediaFormat.KEY_MIME)
&& trackFormat.getString(MediaFormat.KEY_MIME).contains("video"))
|| (trackFormat.containsKey(MediaFormat.KEY_WIDTH) && trackFormat.containsKey(MediaFormat.KEY_HEIGHT))
) {
videoTrackMediaFormat = trackFormat;
break;
}
}
return videoTrackMediaFormat;
}
And here is sample code on how to use it.
String TAG = "DEBUG"; // Define your tag
int profileCode = getVideoEncodingProfile(videoInfo.getLocalVideoPath());
switch (profileCode) {
case MediaCodecInfo.CodecProfileLevel.AVCProfileBaseline:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileBaseline");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileMain:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileMain");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileExtended:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileExtended");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileHigh:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileHigh");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileHigh10:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileHigh10");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileHigh422:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileHigh422");
break;
case MediaCodecInfo.CodecProfileLevel.AVCProfileHigh444:
Log.d(TAG, "getVideoEncodingProfile() returned AVCProfileHigh444");
break;
default:
Log.d(TAG, "getVideoEncodingProfile() returned unsupported profile code or code not found.");
}
Hope it helps. If you have other way which supports at least Jelly Bean API level 16
let me know.
For reference, here is a snapshot of MediaFormat
of a video track taken from Nougat 7.1.1
device. (NOTE: Lower level API will return less attributes)
