Hi,
A recent commit added fmp4 support for HLS [1] but byte-range or
single-file isn't supported [2].
Being able to use a single mp4 file for both Dash and HLS will be super
useful.
Any plans to add it?
What's missing?
Is mp4 different than mpegts in regards to byte-range support?

thanks for getting back to me and taking the time to explain.

Thank you Moritz! I will at least consider doing that, but I was beginning
to suspect a bug myself. I just need to find a solution or work around

Hello and thanks for replying.
Your information is very useful and i thank you!
My colleague uses an older version of ffmpeg and the specific
combination (including pix_fmt)
ffmpeg -y -hwaccel cuvid-c:v h264_cuvid
works without any errors.That was my question.I thought i was doing
something
so i've recently received a few corrupted videos that i'm trying to help
some friends recover.
the videos are encoded in ProRes 422 and encapsulated in .mov
these videos have anywhere from a few to many damaged frames. some
damaged frames simply have a few small colored blocks, and others ha

But that was a conversion, right?

Gyan,
I am still very new to video conversion and ffmpeg, so I don't understand
parts of your reply. Please explain:
What is non-standard about my input video?
I ran many conversion commands, and listed several of them in my original
message. Which one did you use?
What does "Muxing to TS" mean
crf stands for constant rate factor. Allowed values are between 0 and 51,
default is 23. To get better quality, use a lower number. The recommended
start value, if the default does not work for you, is 18. 0 is lossless.
You can read on the topic here: https://trac.ffmpeg.org/wiki/Encode/H.265

I'd be interested to know what "crf 23" actually means.
How do I get it to do, say, 2.5Mbps?

Is there a way to fill up the TS stream during encoding with an still image (or
also an other TS) if packets during a UDP transmission (perhaps because of bat

Apparently, you use a differently built ffmpeg in the script.

Hi,
I just realized that all movies that I converted down to 720p using h264 codec
don't play neither on my TV nor my Gigablue Quad box, but work fine with
mplayer/mpv/xine on my Linux system. On the TV/gigablue the video stream
