Hi All,
I'm trying to get Ffmpeg to package and generate a valid fMP4 file for HLS of
an Audio Only Dolby Digital Plus file. However, the stream that I get is
unplayable and has no audio in its sample tables.
Here's an example command:
ffmpeg -i atmosTest.mp4 -codec copy -hls_time 0.993 -hls_s
Hey All,
I noticed that ffmpeg always seems to generate a SIDX box when it's not really
required for Audio Only content.
Example command:
ffmpeg -i atmosTest.mp4 -codec copy -hls_time 0.993 -hls_segment_type fmp4
-hls_flags single_file -hls_playlist_type vod atmosTestffmpeg.m3u8
ffmpeg version

Not a good idea at all. It generates garbage video.

Ok. So is it possible to concatenate 2 vob's where the audio and video don't
have the same stream numbers ?
VOB do not have stream numbers (FFmpeg is inventing them on the fly), so
the question does not make any sense.

So I assume there's no way of making it use HWA automatically via some build
parameters without getting into the code, right?
I'm using a video source filter which wraps itself around ffmpeg and I need it
to do the HWA, which it does not. So if I had an auto-HWA-enabled ffmpeg build,
I could bu
Hi,
You need to specify hardware accelerator to ffmpeg.
You can give hw acceleration name with
-hwaccel option to ffmpeg.
And if you want to use it with any binary then its example code is located at :
doc/examples/hw_decode.c or doc/examples/vaapi_encode.c or
doc/examples/vaapi_decode.c file
Hello!
I have a couple of questions about ffmpeg tool.
When I use the ffmpeg tool that was compiled with support of one of the
hardware accelerators, will the tool automatically use this acceleration while
working? Or it has to be explicitly specified somehow that it must be used?
And if it at

Hello,
I think this report is interesting.
Creating file for broadcast delivery, is not just about having a file which
play or doesn't play
It's mainly about passing Quality Control.
Even if a file can be play in most of software, if it doesn't pass
broadcaster QC, it will be reject.
