Created attachment 8594829 [details] testcase.264 Tested with https://github.com/cisco/openh264/commit/864ff21021
I just replicated this crash with the master branch, but I cannot replicate it with the v1.4-Firefox38 branch (gives a 'Feature not supported' message). So we need to fix this before the next version, but this shouldn't hold up the v1.4 rollout.
yes in 1.4 we disabled the recently-built high-profile support in 1.4.
This problem has been fixed in commit dac1363. The high-profile has been supported in master branch now.
