Failed parsing MP4 file recorded with xiaomi phone

jozefchutka commented 10 months ago

The following video mp4box_issue354.mp4 was recorded with Xiaomi phone and can be played in every player I have tried (chrome, safari, quicktime player, xiaomi players on device) so I believe its a valid example of a common mp4 file. However, trying to parse the video with mp4box v0.5.2 is problematic. I have also tried more Xioami phones with the same result...

Observed issues:

when calling mp4.appendBuffer() with chunk size 65536, the returned value (next offset to be requested) is the same as the fileStart. Which ends in infinite loop of "requesting" the very same data over and over.

<script src="mp4box.all.js"></script>
<script>
(async () => {
const size = 65536;

const blob = await (await fetch("mp4box_issue354.mp4")).blob();
const mp4 = MP4Box.createFile();
let offset = 0;

let buffer = await blob.slice(offset, offset + size).arrayBuffer();
buffer.fileStart = offset;
offset = mp4.appendBuffer(buffer); // returns 405294

buffer = await blob.slice(offset, offset + size).arrayBuffer();
buffer.fileStart = offset;
offset = mp4.appendBuffer(buffer); // returns 405294
})()
</script>

when chunk size is increased to 1048576 (1024*1024), BoxParser logs error (in dev console), however there is no way to handle this error in code as its not being returned or thrown out of mp4box:

<script src="mp4box.all.js"></script>
<script>
(async () => {
const size = 1048576;

const blob = await (await fetch("mp4box_issue354.mp4")).blob();
const mp4 = MP4Box.createFile();
let offset = 0;

let buffer = await blob.slice(offset, offset + size).arrayBuffer();
buffer.fileStart = offset;
offset = mp4.appendBuffer(buffer);

buffer = await blob.slice(offset, offset + size).arrayBuffer();
buffer.fileStart = offset;
offset = mp4.appendBuffer(buffer);

buffer = await blob.slice(offset, offset + size).arrayBuffer();
buffer.fileStart = offset;
offset = mp4.appendBuffer(buffer);
// [0:00:00.230] [BoxParser] Box of type '\x00\x00\x00\x00' has a size 1751411826 greater than its container size 224
})()
</script>

This error seems to be related to https://github.com/gpac/mp4box.js/issues/309 and https://github.com/gpac/mp4box.js/issues/120 , however I believe there are more things to be resolved:

parser fix for .mp4
make sure appendBuffer() throws error or return different value than the provided buffer.fileStart
make BoxParser error handleable (via mp4.onError() api)

jozefchutka commented 9 months ago

The workaround for my file is as following:

use const size = 524288; or greater
once onReady and onSamples is invoked, offset for appendBuffer() to be calculated from the most recent received sample offset = samples[0].offset + samples[0].size

samples can be red now, however BoxParser would still throw the reported error
