Add a new HDV1080 format

[Samuel]

Summary of the wish:
HDV-HD format is not available yet.
​​https://en.m.wikipedia.org/wiki/HDV

How to reproduce:

% ffmpeg -i input -f hdv1080 output

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

[Samuel]

Maybe this is an invalid wish, if you could explain why.

[Elon Musk]

No samples provided.

[Samuel]

Oh...​sorry for having missed that it was need in that case :(

This file is already supported.

I believe a better explanation is that you have to provide a use case: This is typically not necessary if you provide a multimedia file that is not supported by FFmpeg but can be played with another player but it is needed for unclear feature requests such as yours. The use case should not be a Wikipedia link or some random specification but should contain an explanation what you wanted to achieve and why, what you tried and what didn’t work.

[Samuel]

Ok i see.

The PS3 doesn't support HD H.264 and is very picky on the 720p and FFmpeg tickets show that muxing or transcoding output are not reliably accepted by the PS3, so MPEG-2 is sadly the best supported format.

So to keep the HD definition a convertion to MPEG-2 is prefered, and HDV-HD is know to be well supported AFAIK.

[Elon Musk]

Unclear request. MPEG-2 is supported.

[Samuel]

As i said in precedent explaination attempt, that is to avoid to have to set the bufsize, maxrate and others video settings.
Like FFmpeg already do for other formats as DVDs for exemple.

[Carl Eugen Hoyos]

Am I correct that this is the first time you mention the PS3?

Please provide a file that is supported by the PS3 and has the properties you like.

Replying to cehoyos:

I realize that this was a little unclear: This is of course not about a use case but about your use case that you are able to test and reproduce.

Not related to this ticket, this page seems to disagree:
​https://manuals.playstation.net/document/en/ps3/current/video/filetypes.html
It's mentioned elsewhere that 1080@30 is supposed to play.

[Samuel]

We all know the official specifications and discovered some of their limitations or omission over time, like it support AC-3 but not the one produced by FFmpeg.

Nothing best than real tests ;-)

Not related to this ticket, these pages seem disagree:
​https://trac.ffmpeg.org/ticket/2515

As well as hundred of forum threads since many years, that probly explain why media server are streaming MPEG-2 to the PS3 ;-)

[Samuel]

Yes, i never mentioned PS3 before because i didn't see the need, so if was wrong i apology for that.

[Samuel]

@Richard Yes, but encoding MPEG-2 HD with ffmpeg show plenty of overflow warning# messages in the log, like the mpeg format was only done for SD. Changing the bufsize and maxrate didn't fixed it.
