TAF limit 2GB #181

Closed ks61625 closed 5 months ago

ks61625 commented 6 months ago

Problem

Having a web stream assigned to a tag, the playback stops after certain time (~2-3 hours) when 2GB of TAF was reached.

Guess

Maybe there is a (firmware) setting to limit each TAF to 2 GB.

Reproduction

TC Settings:

Opus bitrate = 96
Stream buffer ms = 5000
Stream force restart = true
Sweep stream prebuffer = true
Sweep delay ms = 2000

also tried, with same result:

Stream buffer ms = 2000
Stream force restart = false

Expectation

The TAF should be able to be 4GB as this would be FAT32 limit.

Fix (idea)

If firmware related, maybe this can be patched with another overwrite on sd-card (revvox/boot/patch/4gbTaf.json)

SciLor commented 5 months ago

The max size is INT32, so 2GB is fine. I don't think the reason for the stop is the filesize. Maybe just the streams buffer was empty.

ks61625 commented 5 months ago

Mhm - what exactly ist ment with stream buffer was empty? Or how could it get empty, actualy?

In the test i made, the streaming resource is a 24/7 never ending stream. On the other hand there is ffmpeg on teddycloud, consuming this stream. Do you mean, smth. happend to ffmpeg while encoding, causing the breach / empty buffer to toniebox?

SciLor commented 5 months ago

The buffer of the toniebox could be empty during download. The reason for that could be the toniebox buffer itself. Or the ffmpeg streams buffer.
