Problem with (at least) h263
Opened this issue · 10 comments
What steps will reproduce the problem?
1.Using FFmpeg 1.2.3
2.Using FFmpeg 1.1.6
What is the expected output? What do you see instead?
- Expected : Working Telepresence video flow
- Instead : Green/Black screen (depending the client), and full of
"***ERROR: function: "tdav_codec_h263_encode()"
file: "src/codecs/h263/tdav_codec_h263.c"
line: "297"
MSG: Invalid parameter"
in the Telepresence log.
What version of the product are you using? On what operating system?
Telepresence rev998 hosted on a 64b Ubuntu 12.04.
Please provide any additional information below.
If I use h264 on my Linphone windows client, I have a video flow, but with h263
(my Linphone linux doesn't have h264) I get only errors and no video.

Just for information, I added the support of h264 to my Linphone linux clients.
With h264 on every clients it's working well.
Hope you can help me fixing the problem with h263p/h263.

Thanks for the reply.
Sorry for the lack of informations.
First, in addition to the others details I gave in my first post, I used
Doubango rev998.
So I created a conference room at the number 6302 in my Asterisk 1.4.
Telepresence is currently running on my personnal laptop, while I use Linphone
(1 Linux & 1 Windows) on 2 others laptops for tests purposes.
Like I said previously, it's full working with h264.
But with h263/h263+ the telepresence binary just crash.
I joined the full log.
Thank for your work and your help !

Hi,
I believe it is a typo in doubango:
doubango/tinyDAV/src/codecs/h263/tdav_codec_h263.c:297
remove !out_data from the condition, then recompile and h263 will work

must not remove "!out_data", this is *not* a typo. How do you want to deal with
a null pointer to pointer?

we are talking about the function tdav_codec_h263_encode(tmedia_codec_t* self,
const void* in_data, tsk_size_t in_size, void** out_data, tsk_size_t*
out_max_size)
And as far as i can tell, the out_data is not used anywhere in the function. I
took as a reference the
tdav_codec_h264_encode(tmedia_codec_t* self, const void* in_data, tsk_size_t
in_size, void** out_data, tsk_size_t* out_max_size)
which has the same check
if(!self || !in_data || !in_size){
TSK_DEBUG_ERROR("Invalid parameter");
return 0;
}
and out_data is also not being used anywhere in the h264 encode function (I
assume it is there as a parameter for compatibility?)
I might wrong here, sorry for insisting too much if that's the case.
Thanks,
Sebastian

This is an implementation for a virtual interface at
https://code.google.com/p/doubango/source/browse/branches/2.0/doubango/tinyMEDIA
/include/tinymedia/tmedia_codec.h?r=1062#295. Video codecs doesn't always use
this return parameter because the output size is most likely > MTU while audio
codecs use it. As already said, this parameter must be checked and the code is
correct. "out_data" cannot be null as the encode() function is called from
https://code.google.com/p/doubango/source/browse/branches/2.0/doubango/tinyDAV/s
rc/video/tdav_session_video.c?r=1062#437 and
https://code.google.com/p/doubango/source/browse/branches/2.0/doubango/tinyDAV/s
rc/video/tdav_session_video.c?r=1062#441. Even if "video->encoder.buffer" is
null "&video->encoder.buffer" cannot be null.

Additional info: h263 is listed in the supported codecs (for telepresence) but
it's not maintained and we're planing to remove it.
