From bcec568ea7556d122b79bf802b1ac3ff814531f6 Mon Sep 17 00:00:00 2001 From: Kenshin Date: Mon, 24 Jan 2022 22:47:14 +0100 Subject: [PATCH] Add ffmpeg progress tracking to FFmpegFD Add ffmpeg progress tracking to FFmpegPostProcessor Apply changes from the code review Fix a bug where the subprocess didn't capture any output thus an empty stdout and stderr were sent back Add missing hooks Revert "Add missing hooks" This reverts commit a359c5ea10bb35b965e80801e736f43cdbcf3294. Add support of -ss=132 timestamp format Infer filename from ffmpeg args instead of info_dic Remove redundant parenthesis and switch from to_stodout to to_screen Add info kwarg with multiple files and ffmpeg to track progress Moved format progress function to util Moved format progress function to util Add progress tracking to postprocessing operations Fix typing error Handle self._downloader is None at __init__ Move format progress functions to utils Move format progress functions to utils Handle case where ydl passed is None Handle case where ydl passed is None Handle case where _multiline isn't initialized Handle case where _multiline isn't initialized Fix streams incorrectly returned Fix case where ydl is nested in the downloader Add progress_hook attribute Fix bug after merge Fix import bugs after merge Catch up with upstream Fix merge errors #1 Adapt tests and implementatation for ffmpeg progress tracking args --- test/test_downloader_external.py | 11 +- yt_dlp/downloader/common.py | 77 ++------- yt_dlp/downloader/external.py | 38 ++--- yt_dlp/downloader/http.py | 5 +- yt_dlp/downloader/rtmp.py | 5 +- yt_dlp/postprocessor/common.py | 132 +++++++++++++-- yt_dlp/postprocessor/ffmpeg.py | 277 +++++++++++++++++++++++++++++-- yt_dlp/utils/_utils.py | 48 ++++++ 8 files changed, 473 insertions(+), 120 deletions(-) diff --git a/test/test_downloader_external.py b/test/test_downloader_external.py index 62f7d45d4..c610ba012 100644 --- a/test/test_downloader_external.py +++ b/test/test_downloader_external.py @@ -120,19 +120,22 @@ class TestFFmpegFD(unittest.TestCase): downloader._call_downloader('test', {**TEST_INFO, 'ext': 'mp4'}) self.assertEqual(self._args, [ 'ffmpeg', '-y', '-hide_banner', '-i', 'http://www.example.com/', -
