ffmpeg_streaming capture Webcam
10 décembre 2022, par Anoop YadavI am trying to run the following example from https://github.com/aminyazdanpanah/python-ffmpeg-video-streaming : To capture the webcam and convert it to hls.


import ffmpeg_streaming
import logging

from ffmpeg_streaming import Formats

logging.basicConfig(level=logging.DEBUG)

video = ffmpeg_streaming.input(r"Integrated Webcam", capture=True)

hls = video.hls(Formats.h264())
hls.auto_generate_representations()
hls.output(r'C:\PycharmProjects\hls\hls.m3u8')



To list the webcam I used the command :
ffmpeg -list_devices true -f dshow -i dummy


Output :


[dshow @ 0000025f5317ecc0] "Integrated Webcam" (video)
[dshow @ 0000025f5317ecc0] Alternative name "@device_pnp_\\?\usb#vid_0bda&pid_5673&mi_00#6&15ef479&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}\global"

I am getting this error :

I have also tried with alternate name, but error is still same. I think error is with the arguments for
ffprobe
. How can I fix the arguments ?

PGS subtitle track is out of sync after extracting then adding to another video file
23 décembre 2022, par DiericxI have the Japanese and English version of a show. I am attempting to extract the subtitles and audio from the English version and add them to the Japanese version.


The video in both files seems to be exactly the same.


Here is the info for the streams contained in the english file. When playing this source video file
Track 2
subtitles seem to be almost empty whileTrack 1
contains all of them forced.

I extract the english audio


ffmpeg -i s01e01_ja.mkv \
-muxdelay 0 \
-map 0:1 \
-vn \
-acodec copy \
s01e01_en_audio.dts



I extract the english subtitles


ffmpeg -i s01e01_en.mkv \
-muxdelay 0 \
-map 0:3 \
-vn \
-c copy \
s01e01_en_sub.sup



I add the english audio track to the japanese video


ffmpeg -i s01e01_ja.mkv \
-i s01e01_en_audio.dts \
-muxdelay 0 \
-map 0 \
-map 1:a \
-c copy \
-shortest \
s01e01_en_ja.mkv



And finally add the english subtitles to the new japanese video that contains english audio


ffmpeg -i s01e01_en_ja.mkv \
-itsoffset 6 \
-i future_boy_conan_s01e01_en_sub.sup \
-muxdelay 0 \
-map 0 \
-map 1:s \
-c copy \
-shortest \
s01e01_en_ja_subs.mkv



As you can see I need to offset the subtitles by 6 seconds in order to get the subtitles to sync with the audio. The english audio is in sync with the video.


I do not know how to debug this in order to tell if the subtitles are extracted or injected incorrectly causing the time offset. Any help would be appreciated !

ffmpeg works with laptop webcam but not with android camera
28 février 2023, par Rajkumar SomasundaramI am working on Macbook with M1 Chip with this ffmpeg version locally installed.


ffmpeg version 5.1.2 Copyright (c) 2000-2022 the FFmpeg developers 
built with Apple clang version 14.0.0 (clang-1400.0.29.202)



With this, I am able to use my laptop's webcam as input and do my ffmpeg work.


Following command is what worked (avfoundation was needed for OSX)


ffmpeg -f avfoundation -framerate 30 -i 0:0 \
-map 0:v:0 -map 0:a:0 \
-pix_fmt yuv420p \
-c:v libx264 -profile:v high \
-crf 32 -ar 44100 \
-c:a aac \
-filter:v:0 scale=w=480:h=360 \
-utc_timing_url "https://time.akamai.com/?iso" \
-segment_time 8 \
-f dash ${path.join(__dirname, "/output/sample.mpd")}



Now, I am trying to use my android front camera as an input.


But, it is not working. (Errors are mainly in & around camera_index)


I am trying the following command and facing error.


ffmpeg -f android_camera -camera_index 0 -framerate 30 -map 0:v -map 0:a -c:v\
libx264 -profile:v high -c:a aac -filter:v:0 scale=w=480:h=360 \
-utc_timing_url "https://time.akamai.com/?iso" -segment_time 8 \
-f dash ${path.join(__dirname, "/output/sample.mpd")}



This is the stacktrace of the whole error log : https://www.diffchecker.com/Mnnghg7M/

- What is the correct command for android camera as input ?
- Do all stable versions of ffmpeg work with android or any limitations ?
