#3614 closed enhancement (wontfix)

Targa doesn't work with image2pipe

Reported by: Maverick Owned by:

Version: git-master Keywords: targa

Description

I have image001.tga, image002.tga, image003.tga... all being piped into ffmpeg. I'm expecting ffmpeg to accept the tga files and build them into an mp4. However instead it outputs a number of errors and the resulting mp4 is absent or broken.

ffmpeg command and output:
​http://pastebin.com/GSBUEbEh

Additional notes:
-If instead of piping the tga files in I add them in sequentially using image2 then there are no errors and the mp4 file is created perfectly.
-Using the image2pipe command (as seen in the pastebin) with jpg files works perfectly as well.

Do the targa files differ in size?

Please understand that using external resources is not ok, please post all information here in the ticket.

comment:2 by Maverick, 11 years ago

They do in size, but they all have the same dimensions and bit depth.

comment:3 by Carl Eugen Hoyos, 11 years ago

Component: ffmpeg → avcodec
Keywords: tga added
Version: unspecified → git-master

Then please attach two targa files that allow to reproduce the issue and post the failing command line including complete, uncut console output here to make this a valid ticket.

Sorry about that, I've attached the command line and output text files.

The files you attached have the same size (meaning you can use the rawvideo demuxer option -video_size to decode them), do you have samples from the same sequence with different file size?

Replying to cehoyos:

The files you attached have the same size (meaning you can use the rawvideo demuxer option -video_size to decode them)

Sorry for the typo:
It is the image2pipe demuxer option -video_size

comment:7 by Carl Eugen Hoyos, 11 years ago

And the name of the option is -frame_size...

comment:8 by Maverick, 11 years ago

Actually, after checking this out it looks like all the files are the same size on the disk and they are all 1920x1080.

I'm a little confused given the typo with rawvideo/image2pipe; can you give an example command line I should use?

$ ffmpeg -f image2pipe -vcodec targa -frame_size 6220818 -i -

I am not convinced there ever will be a targa parser (which would be necessary to do this without -frame_size).

comment:10 by Maverick, 11 years ago

Sorry to ask, but what is the calculation behind the frame_size? I'm not sure how you are getting 6220818. Thanks again.

comment:11 by Maverick, 11 years ago

Oh, nevermind. It's just the filesize in bytes. Sorry.
