What does "no crop padd module matched 'any'" mean?

[yKevin]

Hi, everyone

I'm working on transcoding of VLC, it's from "mp4v" to "h264".
And when I finished the codec, I try to use the transcoding part to test my codec module,
it seems not work, and the error is like:

[XXXXX]main private debug: looking for crop padd module: 0 candidates
[XXXXX]main private erroe: no crop padd module matched "any"
... ... ... ... ...
Now, my question is:
what is crop, padd?(Sorry, I'm new to the VLC)
And how can I resolve that problem?(I find that many vlc users sufferred it .)
BTW, I used VLC-0.8.6e.

And thanks
Regard

yKevin

Did you specify a crop, padd or canvas option in transcode?

[yKevin]

Did you specify a crop, padd or canvas option in transcode?

Thanks for your reply, dionoea.
And I know nothing about the crop, padd or canvas options in transcode, so I need your help .
Please give me more details, it'll be better if there are some docs(linkage) about these options .

Thanks again.
Regards

Hum ... can you paste the full debug log from your transcode line? (make sure to include -vvv on your command line)

[yKevin]

OK, here comes the full debug info...

These lines look severely wrong:

Do you use your own module to encode only or also to decode? (btw, what does VPU mean?)

Cheers,

[yKevin]

I use my own encoder and decoder both.
Actually, I choose the "transcode" function of VLC is to test the two modules.
OK, and I'm surprised that why do you think the log you quoted is the key point of my problem?

PS. VPU means Video Process Unit or something like that, it doesn't matter.

yKevin

[dionoea]

Well it looks like your decoder forgot to set the aspect ratio. This 0 aspect ratio can in turn trigger a request for the crop padd module in transcode (if I remember correctly).

[yKevin]

Greate, you are the man.
I'll check about that and post a reply about the result.
Thank you.

Regards
yKevin

[yKevin]

And another question I want to get the answer:
Is it correct that I put the decoder and encoder in the same module(.so file), and I'll invoke them in the same process?

Thank you.
Regards
yKevin

[dionoea]

Sure, that's correct (and it's the way we do it for most encoder modules).

[yKevin]

OK, thank you for your warm-hearted.
Good Luck to you.

yKevin

[dionoea]

Did you get all your errors fixed?

[yKevin]

Not yet, actually.
And the problem is still on the transcoding part.
The issue is:
I don't know every member of the structure picture_t exactly, and when I try to return a picture_t variable in decoder module, it will cause a "segmentation fault".
And I want to know which member of picture_t will store the decoded stream(the yuv format data)? I thought it maybe one of these two:
plane_t p[ VOUT_MAX_PLANES ]; or uint8_t *p_data; , but seems something goes wrong.
Here is the definition of struct picture_t:

Code: Select all

struct picture_t { /** * The properties of the picture */ video_frame_format_t format; /** Picture data - data can always be freely modified, but p_data may * NEVER be modified. A direct buffer can be handled as the plugin * wishes, it can even swap p_pixels buffers. */ uint8_t *p_data; void *p_data_orig; /**< pointer before memalign */ plane_t p[ VOUT_MAX_PLANES ]; /**< description of the planes */ int i_planes; /**< number of allocated planes */ /** \name Type and flags * Should NOT be modified except by the vout thread * @{*/ int i_status; /**< picture flags */ int i_type; /**< is picture a direct buffer ? */ vlc_bool_t b_slow; /**< is picture in slow memory ? */ int i_matrix_coefficients; /**< in YUV type, encoding type */ /**@}*/ /** \name Picture management properties * These properties can be modified using the video output thread API, * but should never be written directly */ /**@{*/ int i_refcount; /**< link reference counter */ mtime_t date; /**< display date */ vlc_bool_t b_force; /**@}*/ /** \name Picture dynamic properties * Those properties can be changed by the decoder * @{ */ vlc_bool_t b_progressive; /**< is it a progressive frame ? */ unsigned int i_nb_fields; /**< # of displayed fields */ vlc_bool_t b_top_field_first; /**< which field is first */ /**@}*/ /** The picture heap we are attached to */ picture_heap_t* p_heap; /* Some vouts require the picture to be locked before it can be modified */ int (* pf_lock) ( vout_thread_t *, picture_t * ); int (* pf_unlock) ( vout_thread_t *, picture_t * ); /** Private data - the video output plugin might want to put stuff here to * keep track of the picture */ picture_sys_t * p_sys; /** This way the picture_Release can be overloaded */ void (*pf_release)( picture_t * ); /** Next picture in a FIFO a pictures */ struct picture_t *p_next; };

Thanks

Decoded data is stored in the plane_t structures.
