Safari sends excessive HTTP range requests during HTML5 MOV playback
28 mai, par LucyI am currently developing a web application based on React and Next.js, and I use the react-player library to play user-uploaded videos stored on AWS S3. The supported upload video formats are mp4, mov, and mkv, with codecs including H.264 or H.265 (HEVC).


Problem


However, some
H.264videos in themovformat exhibit noticeably poor playback performance only in the Safari browser. The videos do not play smoothly and frequently experience stuttering or delays.

How Safari Handles Range Requests (As I Understand It) :


- 

- Safari first sends a normal GET request to check if the server supports Range requests. If the server responds with the header Accept-Ranges : bytes, Safari closes the connection.
- Then, Safari sends a very small range request like Range : bytes=0-1 to confirm it receives a 206 Partial Content response.
- Next, Safari requests some parts from the beginning and the end of the file to locate metadata such as the moov atom in MP4 files.
- After that, actual streaming begins, but Safari does not request the entire file at once ; instead, it divides the needed parts into multiple small Range requests.










Example of Actual Problematic Requests


Below are some of the Range requests Safari makes for the problematic
.movvideo (H.264 codec) :

# Request - 1
Connection: keep-alive
Range: bytes=0-1

# Response
HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Disposition: attachment;filename*=utf-8''test.mov
Content-Length: 2
Content-Range: bytes 0-1/102801747
Content-Type: video/quicktime

-------------------------------------
# Request - 2
Connection: Keep-Alive
Range: bytes=0-102801746

# Response
HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Disposition: attachment;filename*=utf-8''test.mov
Content-Length: 102801747
Content-Range: bytes 0-102801746/102801747
Content-Type: video/quicktime

-------------------------------------
# Request - 3
Connection: Keep-Alive
Range: bytes=102760448-102801746

# Response - 3
HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Disposition: attachment;filename*=utf-8''test.mov
Content-Length: 41299
Content-Range: bytes 102760448-102801746/102801747
Content-Type: video/quicktime

-------------------------------------
# Request - 4
Connection: keep-alive
Range: bytes=3014656-3080191 # 64KB

# Response - 4
HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Disposition: attachment;filename*=utf-8''IMG_7929.mov
Content-Length: 65536
Content-Range: bytes 3014656-3080191/102801747
Content-Type: video/quicktime


Safari continues to send hundreds of similar small Range requests repeatedly, gradually downloading the file.


This causes increased network load, which ultimately leads to video stuttering or playback delays.


Example of another
.movfile that works properly :

In contrast, another .mov video using the same format and codec (H.264) sends Range requests over much larger byte ranges, downloading about 30MB of data at once. In this case, the video plays smoothly.


# Request 
Connection: Keep-Alive
Range: bytes=1310534-673918954 # Request : 672MB, Actual Downloaded : 32MB

# Response
Accept-Ranges: bytes
Content-Disposition: attachment;filename*=utf-8''mov-example-video-download-4k-uhd-3840x2160.mov
Content-Length: 672608421
Content-Range: bytes 1310534-673918954/673918955
Content-Type: video/quicktime


Question


In Safari, for certain video files, the browser repeatedly closes the connection after receiving only a few kilobytes per request and immediately sends the next request. As a result, dozens or even hundreds of small range requests occur consecutively. This causes increased connection overhead and latency, and although the web server can deliver data at sufficient speed, the player does not receive data in time, leading to poor and stuttering video playback.


- 

- What could be the reason Safari repeatedly makes these very small requests for certain files ?
- Could the internal structure of the video file (such as the moov atom) influence this request pattern ?






f you have any similar experience or advice, please share.


What I'ved tried


- 

- Using
ffmpegto move themoov atomto the beginning of the file with-movflags faststartdoes not resolve the issue — the same problem persists. - Converting the exact same video to MP4 format and testing it results in normal playback without issues.






Test Environment


- 

- Macbook pro 16
- mac OS - Sequoia 15.5
- Safari - Latest








File information


Due to company policy, I am unable to share the problematic video files directly. However, I am attaching the file information obtained via ffprobe for your reference.

avformat/iamf : fix setting channel layout for Scalable layers
17 juin, par James Almeravformat/iamf : fix setting channel layout for Scalable layers
The way streams are coded in an IAMF struct follows a scalable model where the
channel layouts for each layer may not match the channel order our API can
represent in a Native order layout.For example, an audio element may have six coded streams in the form of two
stereo streams, followed by two mono streams, and then by another two stereo
streams, for a total of 10 channels, and define for them four scalable layers
with loudspeaker_layout values "Stereo", "5.1ch", "5.1.2ch", and "5.1.4ch".
The first layer references the first stream, and each following layer will
reference all previous streams plus extra ones.
In this case, the "5.1ch" layer will reference four streams (the first two
stereo and the two mono) to encompass six channels, which does not match out
native layout 5.1(side) given that FC and LFE come after FL+FR but before
SL+SR, and here, they are at the end.For this reason, we need to build Custom order layouts that properly represent
what we're exporting.
Before :

Flutter Android release crash with ffmpeg_kit_flutter_new : Bad JNI version returned from JNI_OnLoad in libffmpegkit_abidetect.so (debug works) [closed]
20 août, par Muhammad Rakha AlmasahProblem
My Flutter app crashes only in release when the FFmpegKit plugin is registered. The app runs fine in debug on the same devices. The crash happens before my UI shows up, during plugin registration.

What’s strange
In debug the plugin loads and prints :


I/ffmpeg-kit: Loaded ffmpeg-kit-full-gpl-arm-v7a-neon-6.0-20250810.


and the app works normally.


Environment


Flutter (stable), Android


compileSdk = 35, minSdk = 24, targetSdk = 35


NDK I tried :


26.1.10909125 (recommended by many plugins)


25.2.9519653


Devices that crash in release :


Samsung SM-A105G (32-bit only, API 30)


Redmi 24094RAD4G (arm64-v8a capable, API 35)


Dependencies (relevant)


I mainly need FFmpeg through a video editor workflow.


Tried these FFmpeg packages :


ffmpeg_kit_flutter_new 3.2.0 → release crash


ffmpeg_kit_flutter_new 1.6.1 → release crash


(for testing) the discontinued ffmpeg_kit_flutter 6.0.3 → gradle couldn’t resolve com.arthenica:ffmpeg-kit-https:6.0-2 in release


Other media deps : video_editor (git), video_thumbnail (git), video_player, etc

APK / AAB inspection


jar tf app-release.apk | findstr ffmpegkit_abidetect shows the library is packaged, e.g. :


lib/arm/libffmpegkit_abidetect.so (on 32-bit build)


lib/arm64-v8a/libffmpegkit_abidetect.so (on 64-bit)


So the .so is present in the release artifact.


What I tried


Switch NDK 25.2 ↔ 26.1 and align with plugins.


Add android:extractNativeLibs="true" in the manifest.


packagingOptions jniLibs useLegacyPackaging true .


Build both APK and AAB, and also flutter run —release -d .


With and without abiFilters.


Full flutter clean, delete Gradle caches, rebuild.


Verified .env files and other assets are included (unrelated but checked).


The crash always happens at plugin startup in release with :
Bad JNI version returned from JNI_OnLoad in ... libffmpegkit_abidetect.so : 0.
