From 6e65a2a67e075ae8f3e4fe03c732d7772d36f5e1 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Stefan=20P=C3=B6schel?= Date: Fri, 18 Sep 2020 00:26:56 +0200 Subject: [PATCH] [downloader/hls] Fix incorrect end byte in Range HTTP header for media segments with EXT-X-BYTERANGE (#24512) (closes #14748) The end of the byte range is the first byte that is NOT part of the to be downloaded range. So don't include it into the requested HTTP download range, as this additional byte leads to a broken TS packet and subsequently to e.g. visible video corruption. Fixes #14748. --- youtube_dl/downloader/hls.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/youtube_dl/downloader/hls.py b/youtube_dl/downloader/hls.py index 84bc34928..0f2c06f40 100644 --- a/youtube_dl/downloader/hls.py +++ b/youtube_dl/downloader/hls.py @@ -141,7 +141,7 @@ class HlsFD(FragmentFD): count = 0 headers = info_dict.get('http_headers', {}) if byte_range: - headers['Range'] = 'bytes=%d-%d' % (byte_range['start'], byte_range['end']) + headers['Range'] = 'bytes=%d-%d' % (byte_range['start'], byte_range['end'] - 1) while count <= fragment_retries: try: success, frag_content = self._download_fragment( -- 2.39.5
