I'd perfer if you could forward the ENOMEM error as a function return value and remove the error message.

OK, I'll had to change more code and return the error code for the function first. > > Thanks, > Marton > > > ret = pthread_mutex_init(&s->mutex, NULL); > > if (ret != 0) { > > av_log(h, AV_LOG_ERROR, "pthread_mutex_init failed : %s\n", strerror(ret)); > > -- > > 1.8.3.1 > > > > _______________________________________________ > > ffmpeg-devel mailing list > > ffmpeg-devel@ffmpeg.org > > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > > > To unsubscribe, visit link above, or email > > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
