#14 DashCast SIGSEGV in dc_read_configuration()

[Urs Muller]

Hi,

Running DashCast (r4780) on Ubuntu 12.04 64bit results in a segmentation fault in cmd_data.c:128 (strcpy(p_vconf->psz_codec, gf_cfg_get_key(p_conf, psz_sec_name, "codec")).

Apparently, the key "codec" is not found and gf_cfg_get_key() returns NULL;

I'm using the example dashcast.conf file from http://gpac.wp.mines-telecom.fr/dashcast/ and a simple example mp4 file from http://download.wavetlan.com/SVV/Media/HTTP/H264/Talkinghead_Media/H264_test1_Talkinghead_mp4_480x360.mp4

The exact call is:
DashCast -av H264_test1_Talkinghead_mp4_480x360.mp4 -seg-dur 1000 -frag-dur 200

I'm probably doing something wrong. Any ideas?

Thanks,
Urs

Hi Urs,

The parsing of incomplete config files was not robust enough. Can you update again and retry?

Thanks,

Romain

Hi Romain,

Yes, that fixed the problem. The code no longer crashes.

Thanks for the very quick turnaround.
