[bug] corrupt when loading local hls files with asset protocol

[conanchen]

Describe the bug

currupt when loading local hls files with asset protocol

Reproduction

1. copied player code from vimejs
2. used convertFileSrc

<script lang="ts">
  import { convertFileSrc } from "@tauri-apps/api/tauri";

  import { onMount } from "svelte";

  let showPlayer = false;
  let player;

  onMount(async () => {
    const { defineCustomElements } = await import("@vime/core");
    defineCustomElements();
    showPlayer = true;
  });

  const posterlocal = convertFileSrc("/Users/CC/posterlocal.png");
  const datasrclocal = convertFileSrc(
    "/Users/CC/resources/master.m3u8"
  );
  console.log("posterlocal=", posterlocal, " datasrclocal=", datasrclocal);
</script>

<div class="w-full h-full">
  <div><img alt="poster.png" src={posterlocal} /></div>
  <br /><br />
  {#if showPlayer}
    <vm-player bind:this={player}>
      <vm-hls version="latest" poster={posterlocal}>
        <source data-src={datasrclocal} type="application/x-mpegURL" />
      </vm-hls>

      <!-- We turn off the controls that come with the default UI. -->
      <vm-default-ui no-controls>
        <!-- We setup the default controls and pass in any options.  -->
        <vm-default-controls hide-on-mouse-leave active-duration="2000" />
      </vm-default-ui>
    </vm-player>
  {/if}
</div>
<svelte:head>

[lucasfernog]

Thanks for the report. I'll look into this over the weekend.

[lucasfernog]

I don't think the webview supports loading m3u8 files directly. I also tried on Chrome and on Safari and it didn't work. Do you see any evidence this might work?

[conanchen]

asset::// protocol works with local m3u8 file.
I added println! to manager.rs to check the range parsing

        // handle 206 (partial range) http request
        if let Some(range) = request.headers().get("range").cloned() {
          let mut status_code = 200;
          let path_for_data = path_for_data.clone();
          println!("path_for_data={}",path_for_data);
          let (headers, status_code, data) = crate::async_runtime::safe_block_on(async move {
            let mut headers = HashMap::new();
            let mut buf = Vec::new();
            let mut file = tokio::fs::File::open(path_for_data.clone()).await.unwrap();
            // Get the file size
            let file_size = file.metadata().await.unwrap().len();
            // parse the range
            let range_ = HttpRange::parse(range.to_str().unwrap(), file_size);


            println!("path_for_data file_size={} {:?} range_={:?}",file_size , range.to_str(), range_);
          
            let range = range_.unwrap();

            // FIXME: Support multiple ranges

and found it return an invalid range:

path_for_data file_size=375 Ok("bytes=0-*") range_=Err(InvalidRange)
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: InvalidRange', /Users/CC/github/tauri-apps/tauri/core/tauri/src/manager.rs:352:32

1. test with correct local m3u8 master and sub files , the player can play local m3u8 files

[conanchen]

test with below updated manager.rs by checking file/range before unwrap(), works now.

        // handle 206 (partial range) http request
        if let Some(range) = request.headers().get("range").cloned() {
          let mut status_code = 200;
          let path_for_data = path_for_data.clone();
          println!("path_for_data={}", path_for_data);
          let (headers, status_code, data) = crate::async_runtime::safe_block_on(async move {
            let mut headers = HashMap::new();
            let mut buf = Vec::new();
            let mut file = tokio::fs::File::open(path_for_data.clone()).await;

            if file.is_ok() {
              let mut file_ = file.unwrap();
              // Get the file size
              let file_size = file_.metadata().await.unwrap().len();
              let file_size_ = format!("{}", file_size);
              let ss = range.to_str().unwrap();
              // parse the range
              let range_ = HttpRange::parse(&ss.replace("*", &file_size_), file_size);

              println!(
                "path_for_data file_size={} {:?} range_={:?}",
                file_size,
                range.to_str(),
                range_
              );

              let range = range_.unwrap();

              // FIXME: Support multiple ranges
